Even the most well-planned commercial construction projects can fail if the ground beneath them isn’t properly prepared. One common reason behind this is inadequate soil compaction: a critical step that involves the mechanical densification of soil to form a firm foundation that will support structures. 

Poorly compacted soil may not exhibit any signs of failure immediately; rather, such signs emerge gradually: a microscopic crack on the concrete surface, a door that cannot be shut, or an area of road surface beginning to sink.

In this blog, we break down the very causes behind these consequences of poor soil compaction and the right approach to preventing it, so you know exactly what to watch out for on your next commercial project!

What Does Soil Compaction Mean?

Picture the soil as a sponge packed with tiny air pockets. On its own, those gaps keep the ground soft, unstable, and likely to shift the moment any real pressure is applied. Soil compaction is the process of closing those gaps, pressing the particles together until the ground is dense and solid enough to actually hold what’s being built on top of it.

What does it do?

Once those air pockets collapse and the particles lock into place, the ground transforms. It ceases to be a flexible material that is hard to predict and begins to behave like a stable foundation for other building materials, such as foundations, slabs, and pavements. It offers resistance to movement, distributes loads evenly on the surface, and maintains its shape. On top of all that, it avoids any future problems associated with uneven settling and moisture intrusion.

Causes of Poor Soil Compaction

Poor soil compaction is usually the result of improper timing, unsuitable soil conditions, poor equipment use, or lack of site-specific planning. When these issues are ignored during early site preparation, the ground may fail to reach the density needed to support heavy commercial structures, pavement, utilities, and drainage systems.

Compaction of Wet Soil

It is not advisable to perform compaction when the soil is moistened. This is because operating equipment on wet soil will displace the particles instead of compressing them. Ultimately, due to excessive water content, wet soil particles will not adhere to one another.

Too Few Passes

Compaction isn’t a one-pass job. Operators who don’t make enough passes over the same piece of soil leave air voids behind that aren’t visible on the surface but will absolutely show up later, in the form of settling, cracking, and shifting. 

Low Organic Content in Soil

Soil with high organic content has a built-in structural integrity. The organic material binds all the elements together without being compressed. In soil lacking in organic content, there is no cohesive substance holding it up, thus making the soil highly susceptible to bad compaction right off the bat.

Ignoring Soil Variability Across the Site

Most commercial sites don’t have uniform soil throughout. Pockets of clay, sand, or fill material all behave differently under compaction from varied equipment, as different soils require different types of rollers. Whereas soils such as gravel and sand can readily yield to the vibrations used in soil compaction, soils such as clay and silt need much more labor-intensive methods.

In addition, the effectiveness of the compaction depends on the proper excavation of construction project and preparation of the site.

What are the Consequences of Poor Soil Compaction?

Poor soil compaction can create serious structural, operational, and financial problems long after construction is complete. From foundation movement to pavement failure and drainage issues, weak soil support can compromise the safety, performance, and lifespan of a commercial property.

Uneven Foundation Settlement

The condition of poor soil compaction creates an uneven subsurface, meaning different sections of the ground respond differently under load. Areas with loosely compacted or higher air-void content compress more under pressure, while denser sections remain relatively stable. Because of this differential stress, cracks form, sloping floors occur, and once tightly fitting doors no longer close!

Cracks and Buckles in Concrete Slabs

A major part of soil compaction problems is that the movement of unstable soils causes concrete to pull away from the ground. Cracks develop, the slab sags, and the structure becomes a danger rather than serving as a durable surface for commercial activity. 

Failure of the Drainage System

Water drains differently when the underlying soil is unstable. Instead of flowing where you want it to go, it goes somewhere else or settles in spots where you do not want it. Poor soil conditions are one of the leading reasons underground utility installation requires careful planning on commercial sites.

Pavement and Parking Lot Wear

In commercial spaces, parking lots and access roads take constant traffic. When the base isn’t properly compacted, these surfaces start to deform under repeated use, leading to uneven areas, tire ruts, and a noticeably rough driving surface much sooner than expected. 

Legal and Financial Fallout

Structural failures that trace back to poor ground preparation don’t stay quiet. They turn into lawsuits, insurance claims, and reputations that take years to rebuild. The fix always costs more after the fact than it ever would have upfront. 

Construction decisions made early in a project carry their own long-term consequences, as outlined in our breakdown of the pros and cons of prefabrication in modern construction!

How to Prevent Poor Soil Compaction?

Preventing poor soil compaction starts with proper testing, planning, equipment selection, and continuous site supervision. By verifying soil conditions and compacting each layer correctly, commercial construction teams can reduce settlement risks and build a stronger foundation for long-term performance.

Have a Soil Test Prior to Starting Work

Prior to using any piece of machinery, a geological survey should have been conducted on the land already. This provides an understanding of the nature of the soil and its moisture content. This will form the basis of planning the process and type of equipment need for soil compaction.

Compact the Soil in Layers

It is recommended that soil be compacted in layers not exceeding a thickness of 6 to 8 inches at one go. Filling a large area in one go will result in loosely compacted soil underneath. Also, make sure the systems beneath the structure are just as solid as the structure itself, including avoiding common failures in commercial gas piping systems.

Test and Verify

Commercial construction typically requires 95-98% compaction of maximum dry density, verified through the Proctor compaction test. To prevent soil compaction problems, regular field density tests are conducted throughout the process.

On-Site Inspection and Supervision 

Even if there is an appropriate plan in place, the process may not be successful without sufficient supervision during its implementation. Site inspections are necessary to verify that the lifts, water content, and equipment usage are carried out appropriately.

Earthmoving construction services involve using appropriate equipment to handle various construction tasks effectively. Each task, such as digging, leveling, and clearing the land, requires many different types of earthmoving equipment to be used. 

These machines help make the work process faster, safer, and more efficient, and help builders and other construction professionals plan a project that requires effective, efficient services. So, in this guide, we will help you to get a clear understanding of the equipment required in construction work. 

Essential Earthmoving Equipment and Its Uses

Essential earthmoving equipment helps with digging, leveling, moving materials, and preparing land. It makes construction work easier, faster, and more accurate. Below are the main types and their uses.

Excavators

Excavators are usually machines that are used for digging deep into the ground. They are very helpful in making foundational pits, trenches, and drainage line systems. Their long arms can reach the difficult areas and can break hard surfaces with special attachments such as a hydraulic breaker, grapple, or ripper very easily. Excavators work well on harsh land and are commonly used at the starting of any project. 

Bulldozers

These are earth moving construction machines used to push heavy materials like soil and rocks. Their wide front blade helps them clear the land, remove tree roots, and spread the soil evenly. Bulldozers are especially useful for cutting slopes and preparing rough ground before any construction work begins. 

Backhoe Loaders

Backhoe loaders are very useful machines that can perform both digging and material handling. They have a bucket in front of it and a digging arm at the back. It is great for small jobs, such as digging pits, moving soil, and cleaning sites. 

Wheel Loaders

This earth mover construction equipment is especially useful for handling and moving materials, soil, and sand with ease. They use a large bucket to quickly load the truck and shift it around the site. Wheel loaders are usually used for cleaning work and transporting materials on construction sites. Their strong wheels allow them to move smoothly on solid ground. 

Motor Graders

Used mainly for making the ground smoother and even. They help in leveling the land and shaping it properly. Their long blades can be adjusted to create slopes so that the water can easily flow. They also spread soil and gravel evenly to fix the defected areas, and help to prepare a strong and stable foundation. 

Rollers

Soil compactors or rollers are the earth mover construction equipment that are used for pressing the soil or gravel tightly in the ground so that it can become strong. They work by pressing the materials down with the heavy weight to remove any air gaps between them. It helps to keep the surface firm and stable so that buildings can be built on it carefully. 

Which Factors to Consider When Selecting Earthmoving Equipment?

Choosing the right earthmoving equipment depends on factors like project size, soil type, site conditions, budget, and required efficiency. Considering these helps ensure smooth, safe, and cost-effective work.

Construction Work Type

The type of work to be performed is the most fundamental factor in selecting earthmoving equipment. Different machines are designed for specific operations such as excavation, hauling, grading, or compaction. For example, excavators are ideal for digging and trenching, while bulldozers are better suited for pushing and leveling. Choosing equipment that does not match the task leads to inefficiency, increased cycle time, and higher operational costs. 

Material Characteristics

Another critical factor is the type and characteristics of the material being handled when selecting. Soil properties such as density, moisture content, and hardness directly affect equipment performance. Loose, dry soil can be handled easily with loaders, while wet clay or rocky ground may need heavy-duty machines with special attachments. Choosing the wrong equipment can reduce productivity and increase wear and tear. 

Site Conditions and Terrain

Terrain characteristics such as slope, ground stability, and surface condition play a critical role in equipment selection. Tracked machines provide better traction on soft or uneven ground, while wheeled machines are more efficient on firm and flat surfaces. Site constraints like limited space or obstacles may also restrict equipment size.

Project Size and Duration

The size and duration of the project also matter, as they determine how many earth mover construction equipment will be needed and how long it will take to complete the project. Large projects require large machines that can work for longer hours, while the smaller projects need small machines. If you ignore these factors, it can lead to very common excavation mistakes, such as using the wrong machine for the project. 

Load Capacity

The distance between the excavation site and the dumping area significantly influences equipment choice. Short distances are best handled by bulldozers or loaders, medium distances by scrapers, and long distances by dump trucks or articulated hauliers. Using unsuitable equipment for a given haul distance reduces efficiency and increases fuel consumption.

Machine Fuel Usage and Cost

It shows how a machine will consume the fuel during a project and what the overall cost will be. Machines with high fuel consumption can increase your daily expenses, especially if you are working on a longer project. So make sure to choose the fuel-efficient earth moving construction equipment to reduce your costs and re-fuel time for continuous work. 

Machine Handling Skill Requirements

For these machines, skilled operators are needed who have the level of training to use these equipment. These skilled workers know how to control machines and follow the safety rules on the site. This is very important, especially in commercial and government construction, where each work should be done with strict rules and regulations and high accuracy.

To make it easier to choose the right equipment for your project, seeking professional assistance can be a smart decision. To help you identify a dependable service provider, here are some useful tips for finding the best commercial plumbing company.

Each project needs specific construction equipment, and also working with the right and experienced team can make a lot of difference. Dub-L-EE Construction provides reliable construction services using the right machines for excavation, land clearing, grading, and efficient site preparation across all project types. 

FAQs

Can one machine be used for multiple tasks on a construction site?

Yes, machines like backhoe loaders are designed to handle both digging and material handling, making them a versatile choice for sites where budget or space limits the number of machines used.

What is the difference between a wheel loader and a bulldozer?

A wheel loader is primarily used for picking up and transporting materials like sand and soil, while a bulldozer is built to push heavy materials and clear rough terrain using its front blade.

What type of earthmoving equipment is best suited for soft or unstable ground?

For soft or waterlogged ground, tracked machines like excavators or tracked bulldozers are preferred over wheeled equipment because their wider tracks distribute weight more evenly and reduce sinking.

How does improper equipment selection affect project timelines?

Using an undersized or wrong machine for the job leads to slower progress, more trips, and higher fuel consumption, all of which can delay the project and significantly increase overall costs.

Do operators need specific certifications to run earthmoving equipment?

Yes, most earthmoving machines require operators to hold relevant training certifications or licenses, especially on commercial or government projects where safety compliance and regulatory standards are strictly enforced.

Because of this, it needs to be done carefully, safely, and on schedule. However, excavation work doesn’t always go as planned. Unexpected commercial excavation issues can arise that lead to structural problems, project delays, higher costs, and even safety risks. So what are the common mistakes that occur once the digging begins? In this blog, we’ll walk through some of the most common excavation mistakes and practical ways to avoid them. So let’s begin!!!

Common Excavation Mistakes You Might Be Making and How to Avoid Them

Skipping Proper Site Investigation Before Excavation

One common excavation mistake that is often seen on commercial sites is crews starting excavation without really understanding the ground conditions. When soil testing or utility checks are skipped, surprises show up quickly. Like unstable soil, hidden rock, or groundwater. Suddenly equipment slows down, excavation plans change, and the project schedule starts slipping.

How to avoid? 

Conduct a proper site investigation. In that:

• Geotechnical engineers should analyze soil conditions, 
• Surveyors map the land and locate utilities.

These reports will help plan excavation methods, choose suitable equipment, and prevent unexpected commercial excavation issues once digging starts.

Ignoring Underground Utilities Before Digging Begins

Never start the excavation without confirming what kind of utilities are underground. There can be buried gas lines, water pipes, electrical cables, or communication lines that run through the site. And at the time of digging, one can accidentally strike, and it can 

• Immediately stop the work 
• damage infrastructure
• create serious safety risks for workers.

How to avoid?

• Utility locating specialists should scan and mark underground services. 
• Then, review utility maps and coordinate with local utility providers. It will help crews know exactly where to dig and prevent dangerous and costly accidents.

Handling Excavated Soil the Wrong Way

Safety agencies such as OSHA warn that soil is far heavier than many workers realize. Just one cubic yard of soil can weigh more than 3,000 pounds, roughly the weight of a small car. This makes trench collapses extremely dangerous when excavated soil is placed too close to the trench edges. The pressure created by this extra weight can weaken trench walls and increase the chances of sudden cave-ins.

How to avoid?

• Keep excavated soil at least two feet away from the trench edge. It will keep the excavation stable. 
• You can use trench supports or barriers.

Overlooking Drainage Planning on the Site

Have you forgotten to include a drainage system while planning? Now, the rainfall or groundwater may collect in the pit. And due to this, the soil can become muddy and unstable. And how will it create an excavation problem? Well, this will slow down the equipment movement and can even weaken trench walls.

How to avoid? 

Plan temporary drainage. Use pumps, drainage channels, or sump pits to control water buildup.

Overlooking Basic Safety Practices on the Excavation Site

Sometimes, you are taking care of the small safety steps, like: 

• missing protective barriers around trenches, 
• workers entering excavations without proper access ladders, a 
• lack of warning signs, or 
• ignoring regular safety inspections

These can quietly increase the risk of falls, cave-ins, or equipment-related accidents, and that is why proper excavation is critical.

How to avoid?

Create a strict daily safety routine. 

• Conduct pre-shift inspections, 
• Assign a competent person to monitor excavation conditions, and 
• Safe entry and exit points are installed. 

Letting Miscommunication Slow Down the Entire Excavation Process

Excavation involves several teams: surveyors, engineers, equipment operators, and site supervisors. When communication between them isn’t clear, mistakes can happen easily. For example, incorrect excavation depth or digging in the wrong location can occur simply because instructions or updated plans were not properly shared across the team. And in this situation, the role of technology in modern construction project management becomes important, as digital tools help teams share updated plans and site information quickly.

How to avoid:

• Hold short coordination meetings every day. 
• Give clear instructions, and
• Update site drawings 

Using the Wrong Equipment for the Excavation Job

Have you ever seen teams trying to dig through hard soil with a small excavator just because it’s available on-site? Situations like this waste time and increase equipment strain. The machine has to work much harder than it is designed for, which can slow down the excavation process. In many cases, it can also lead to faster wear, breakdowns, and unnecessary project delays.

How to avoid:

Select excavation equipment based on soil type, project scale, and site conditions. When the right equipment is used from the start, the work progresses faster and with fewer operational excavation problems.

Conclusion

As you can see, most of the common mistakes committed in commercial construction are preventable with the right planning and coordination. To stay up to date, it is always helpful to review the latest excavation safety guidelines and industry standards. Doing so ensures that no critical step is overlooked and every stage of excavation is carried out with proper planning, safety, and efficiency.

Cast iron or PVC are the two most commonly specified options, each offering distinct advantages depending on soil conditions, load requirements, noise control, and project scope. While one material is valued for its strength and durability, the other is favored for corrosion resistance and installation efficiency. Understanding these differences helps engineers, contractors, and property owners avoid costly repairs, premature failures, and unnecessary maintenance. 

Hence, to help you make a confident decision, the sections ahead break down why material choice matters in commercial drainage and outline the key differences between PVC and cast iron, showing exactly where each option performs best and where it may fall short.

Why Material Choice Matters In Commercial Drainage

The role of technology in modern construction has made it clear that material selection is a defining factor in commercial drainage performance, influencing multiple factors. Let’s check them below: 

Durability & Load Resistance

Commercial drainage pipes must withstand constant pressure. Heavy water flow, foot traffic, and equipment weight all push against the system. If the material isn’t strong enough, it will bend or fail. That’s why choosing a tough, load-bearing material is essential.

Corrosion & Chemical Resistance

The drainage systems at many commercial environments regularly encounters detergents, industrial chemicals, and fluctuating pH levels. Some materials react badly to these substances, weakening over time. When you use a corrosion-resistant material, the pipes stay intact longer, maintain smooth flow, and reduce maintenance needs.

Flow Efficiency

When commercial underground drainage pipes have smooth internal surfaces, wastewater moves faster and more consistently. This reduces resistance inside the system, limits debris accumulation, and significantly lowers the chances of blockages, an important factor for reliable performance in commercial facilities.

Compliance & Safety

In the United States, commercial drainage materials must comply with codes such as the International Building Code (IBC), International Plumbing Code (IPC), or the Uniform Plumbing Code (UPC). Approved materials meeting ASTM International and NSF International standards ensure safe wastewater handling, prevent contamination, reduce liability risks, and protect occupants from health hazards, flooding, and structural damage. 

Temperature Tolerance

Systems frequently carry high-temperature wastewater from sources such as commercial kitchens, dishwashers, boilers, laundries, and industrial cleaning processes. Repeated exposure to hot discharge can cause low-grade materials to soften, expand, or lose structural integrity, leading to joint failure or pipe deformation. So it’s important to choose materials with high temperature tolerance that can maintain dimensional stability, resist thermal shock, and ensure long-term reliability even under continuous heavy-duty use.

Noise Reduction

In high-flow commercial drainage systems, wastewater movement can generate significant noise due to turbulence, vibration, and impact against pipe walls. The choice of material directly affects how much sound is transmitted through the building structure. Dense or acoustically engineered materials absorb vibration and reduce sound transfer through walls and floors, making them especially important in hotels, hospitals, offices, and multi-story commercial buildings where noise control is critical.

What Are The Key Differences Between Cast Iron Vs PVC Drainage Pipes

Below, we have mentioned the key differences between cast iron vs PVC drainage pipes in detail:

Best Applications For Each Material

Best Commercial Uses For Cast Iron Drainage Pipes

• High-Rise Commercial Buildings: Ideal for multi-floor structures requiring strong, fire-resistant drainage systems that handle heavy loads.
• Acoustically Sensitive Facilities: Reduces drainage noise in hospitals, hotels, offices, and other occupied commercial spaces.
• Heavy-traffic commercial zones: Can be used in heavy-traffic commercial areas with high parking, loading docks, and other vehicle-accessible zones.
• Legacy Infrastructure & Retrofit Projects: Ensures compatibility with the existing commercial systems for renovation or partial upgrades.

Best Commercial Uses For PVC Drainage Pipes

• Retail, Office Parks, and Commercial Plazas: Suited for long horizontal underground runs serving restrooms and shared commercial utilities.
• Food Service & Light Industrial Facilities: Supports consistent wastewater flow in kitchens, food prep, and light processing operations, where drainage performance must safely coexist with heat-producing equipment and adjacent commercial gas systems used for cooking and process applications.
• Large-Scale Commercial Developments: Allow quicker installations on the vast underground networks of warehouses and facilities.
• New Commercial Construction Projects: Allows flexible system design and efficient routing in modern commercial drainage layouts.

Conclusion

With the guidance above, selecting between cast iron and PVC becomes a more informed decision aligned with a project’s functional and operational needs. Thoughtful material selection during the design stage supports efficient installation, consistent system performance, and reduced disruptions over the life of a commercial facility. When these factors are overlooked, it reinforces why underground utility installation is crucial in new commercial developments. Partnering with experienced professionals such as DUB-L-EE helps evaluate site-specific conditions early, ensuring drainage systems are planned for long-term reliability, compliance, and reduced risk.

FAQ’s

Does Soil Type Affect The Choice Between Cast Iron and PVC Pipes? 

Yes, aggressive soils could affect the lifespan of cast iron, and in unstable soils, the techniques of installing reinforced PVC could be required.

How Does Pipe Material Affect the Accuracy of CCTV Inspection and Leak Detection?

The pipe material also determines the visibility and accuracy of leak detection during inspections. In contrast, while cast iron has a more rugged surface topography, its corroded surface can hide joints, defects, and developing leaks.

Are There Differences In Failure Warning Signs Between Cast Iron And PVC Pipes? 

Yes. Cast iron usually presents some predictive symptoms of failure in the form of corrosion scaling, leaks, rust staining, or a decrease in flow rate. The PVC usually manifests very minimal predictive symptoms and may fail due to cracking, separation, or deformation under load. 

Can Pipe Material Influence Storm water Or Grease Management Compliance? 

Material properties of pipes provide compliance as they are related to grease resistance, joint sealing, and sediment growth. These materials include cast iron, which withstands high temperatures and is amenable to impact, and PVC, which is resistant to corrosion and grease adhesion.

Stormwater management is a very important aspect of a commercial building, especially when considering the impact of heavy rainfall and weather conditions on building infrastructure. If stormwater is not managed and regulated properly, it results in flooding, foundation damage, surface erosion, and operational disruptions.

This is where storm piping becomes essential. It prevents large volumes of water from accumulating around buildings, parking areas, and underground infrastructure quickly and safely. Understanding why your commercial property needs storm piping is the first step toward safeguarding your investment against the growing impact of severe weather, and that’s exactly what this blog will explore.

Understanding Storm Piping Systems

A​‍​‌‍​‍‌​‍​‌‍​‍‌ storm piping system is a series of underground large-diameter pipes made of either concrete, steel, HDPE, or PVC that are designed to collect and carry stormwater. The system collects water that falls on the streets, roofs, roads, and driveways. When it rains, water is collected from the surface through surface drains and catch basins and then flows downhill by gravity. The water is then discharged into safety outlets such as ponds, drainage channels, or rivers that are close by. Also, this system helps prevent flooding and water buildup in cities and works separately from sanitary sewer systems.

What Is The Importance Of Storm Piping For Commercial Properties?

This section explains why underground utility installation is crucial when managing stormwater on commercial properties:

Flood Prevention

Commercial properties generate high runoff due to large impervious areas such as roofs, parking lots, and service roads. Storm piping captures this runoff at collection points and conveys it through engineered pipe networks sized for peak rainfall events. This controlled stormwater drainage system prevents surface ponding, water intrusion into buildings, and flooding of access routes, loading docks, and below-grade spaces, protecting commercial operations and site functionality during heavy storms.

Structural Protection

When the stormwater remains for a long time near the building, it changes the soil behavior gradually under and around the foundation. Over a period, this can cause settlement issues, slab cracking, and loss of subgrade support. Fitting a well-planned storm piping system discharges the overloaded water from the load-bearing zones, stabilizes subsurface conditions, and reduces hydrostatic pressure against walls and footings. The regulated drainage area, thus, serves as a reservoir of the building’s frame and lessens the chances of expensive repair works of the structural system in the ​‍​‌‍​‍‌​‍​‌‍​‍‌future. 

Improves Safety For Customers And Staff

From a site safety perspective, surface water is a liability risk. How? Pooled runoff on parking lots, sidewalks, and entry points increases the chances of slipping, vehicle skidding, and pedestrian accidents. Storm piping takes away the runoff that keeps the areas dry and usable during and after a rain. So, commercial sites become safer for employees, visitors, and delivery traffic.

Supports Business Continuity

Business dependability is strongly influenced by site availability and interior conditions during bad weather. In the same operational context, the commercial gas system pipes’ role supports an uninterrupted energy supply for heating, cooking, and critical processes, making infrastructure reliability essential for commercial facilities. Flooded service drives, loading zones, or entrances can stop operations, damage the inventory, and cause sudden shutdowns.

Enhances Property Value And Longevity

The properly designed storm piping systems on commercial properties are much more resistant to damage from weather and natural forces than those that do not have storm piping. This is one of the many reasons why buyers, tenants, and investors view effective storm drainage systems as a sign of responsible property management. Storm piping will reduce the risk of property damage; it will also reduce continuing maintenance costs, and future repair needs, which all contribute to increasing the property value and extending the life of the Property.

Compliance With Local Regulations

Commercial​‍​‌‍​‍‌​‍​‌‍​‍‌ properties in the United States have to follow the federal stormwater regulations:

• According to the Clean Water Act (33 U.S.C. §1251), implemented through the EPA’s National Pollutant Discharge Elimination System (NPDES).
• As per the EPA rules (40 CFR Parts 122 and 123), numerous commercial establishments linked to Municipal Separate Storm Sewer Systems (MS4s) have the obligation to handle their stormwater runoff and to refrain from discharging pollutants into those waterways that are accessible to the ​‍​‌‍​‍‌​‍​‌‍​‍‌public.

Incorporating​‍​‌‍​‍‌​‍​‌‍​‍‌ stormwater management at the initial stage of a project will help you avoid common mistakes in commercial construction building codes when you coordinate the drainage layout with the regulations. To be in line with these requirements, storm piping systems should handle flow rates, facilitate the release of the discharge to the authorized outlets, and be in accordance with the conditions of the permit, local stormwater regulations, and post-construction runoff control standards established by state and municipal ​‍​‌‍​‍‌​‍​‌‍​‍‌authorities.

Key Components Of An Effective Storm Piping System

• Catch Basins and Inlets: These are the areas where the water is intercepted from the roofs, parking lots, roads, and landscaping surfaces. The appropriate spacing between the two and the correct location of the structure will help ensure that the water is intercepted before the formation of puddles or flows towards structures.
• Underground Storm Pipes: As we have discussed earlier, storm pipes transmit runoff from inlets to discharge points using gravity or controlled slopes. Pipes are made from reinforced concrete, HDPE, or PVC, depending on load and site conditions. And they are hydraulically sized based on rainfall intensity, drainage area, and design storm criteria.
• Manholes and Access Structures: Through manholes, you can inspect, clean, and maintain the commercial storm piping network. These are placed at changes in direction, slope, or pipe size to provide system stability and ease of maintenance for a long period of time.
• Detention and Retention Facilities: These facilities temporarily store stormwater runoff, thereby controlling the discharge of the peak flow and lessening the chances of flooding in the downstream areas. 
• Outfall Structures: It is the final discharge point that safely releases water into approved locations like municipal systems, channels, or natural water bodies. Proper energy dissipation and erosion control measures are employed so that no damage occurs to the downstream area.

Conclusion

To​‍​‌‍​‍‌​‍​‌‍​‍‌ get the best outcome, commercial property owners and project teams should consider drainage and utility planning as a part of their initial design stage.

FAQ’s

What is the Difference Between Storm Piping and Sanitary Sewer Systems? 

The storm piping takes care of rainwater as well as surface runoff. Sanitary sewerage carries the wastewater from toilets, kitchen sinks, and similar locations. Both remain distinct in order to keep everything clean and avoid loading one of these drainage lines.

Does Every Commercial Property Need A Storm Piping System?

Most commercial properties require storm piping, especially those with large roofs, parking areas, or strict local drainage regulations. Requirements depend on site size, zoning rules, and regional rainfall patterns.

How Is A Storm Piping System Designed On A Commercial Property?

The design phase of the storm piping system includes runoff calculations, determining pipe size, slope planning, placing inlets, and, most importantly, coordinating with other utilities below ground to ensure the long-term efficiency of the storm piping system.

When Should A Commercial Storm Pipe System Be Inspected?

Most commercial storm piping systems should be inspected on an annual basis, as well as immediately following major rainstorms, for the discovery of blockages, sediment buildup, or structural problems in the piping system.

One of the most important yet often underestimated components of that responsibility is practical backflow prevention. Commercial properties rely on complex plumbing networks, multiple water entry points, and high-demand systems that can make them more vulnerable to sudden pressure changes. 

When these fluctuations occur, contaminated water can reverse direction and enter the clean water supply, leading to public health, building operations, and regulatory compliance risks. In the sections ahead, we will discuss how effective commercial backflow protection addresses these challenges while strengthening safety, compliance, and long-term system performance.

What Is Backflow

Backflow refers to the unwanted reversal of water flow within a plumbing system, allowing used, contaminated, or non-potable water to enter the clean water supply. It occurs when the normal pressure within a potable water line is disrupted, causing water to move in the opposite direction of its intended path. This reversal typically results from two main conditions: backpressure and backsiphonage.

Backflow poses significant risks because it can introduce chemicals, industrial fluids, irrigation runoff, or biological contaminants directly into a building’s water system. Proper prevention devices, testing, and adherence to building codes in commercial construction are essential to maintaining system integrity.

How Does Backflow Occur In Commercial Properties?

Backpressure Generated by On-Site Mechanical Equipment

Backpressure develops when downstream (system-side) pressure exceeds incoming supply pressure. In commercial facilities, this is commonly caused by:

• Pressurized boilers and hydronic heating loops
• Pressure-boosting pump assemblies
• Elevated water storage vessels
• Industrial processing equipment

When these components generate pressure above the municipal feed pressure, contaminated or chemically altered water can be forced backward into potable lines.

Backsiphonage Due to Sudden Supply Pressure Drops

Backsiphonage occurs when negative pressure develops in the supply line, drawing water from connected systems toward the source. Commercial properties frequently encounter this condition during:

• Fire suppression system activation
• Large-scale irrigation cycles
• High-volume commercial kitchen drawdowns
• Municipal main breaks or maintenance shutdowns

These pressure reductions create a vacuum that draws contaminants into the potable distribution network, reinforcing the importance of commercial plumbing safety protocols.

Unprotected Cross-Connections Throughout the Facility

Commercial buildings contain numerous cross-connection points where potable and non-potable water interface. Common examples include:

• Cooling towers and HVAC make-up lines
• Chemical injection or dilution stations
• Commercial laundry systems
• Janitorial and maintenance washdown stations
• Landscape irrigation manifolds

Without properly installed backflow prevention systems, these cross-connections become high-risk entry points for industrial chemicals, sediment, fertilizers, and biological contaminants.

Aging Infrastructure and Deferred Maintenance

Deteriorated valves, compromised seals, malfunctioning regulators, outdated plumbing configurations, and a lack of water systems utility upgrades can undermine pressure control. Renovations or system expansions may also introduce unprotected cross-connections if not designed in strict compliance with code.

Seasonal and Peak-Load Operational Conditions

During periods of intensive demand, such as summer irrigation, peak occupancy, or heightened equipment use, commercial plumbing systems experience greater pressure fluctuations, increasing the likelihood of backflow events.

Why Backflow Prevention Is Critical For Commercial Properties

Protecting Potable Water Integrity Across High-Demand Systems

Without certified commercial backflow prevention assemblies, pressure fluctuations can allow contaminants to infiltrate potable lines. These contaminants may include industrial solvents, cleaning agents, microbiological hazards, or stagnant water from auxiliary piping systems. Ensuring backflow protection maintains the integrity of the potable supply across all service zones.

Mitigating Operational and Business Continuity Risks

A backflow event can trigger immediate system shutdowns, equipment contamination, or full-building water service interruptions. For facilities such as hotels, healthcare centers, manufacturing plants, and commercial kitchens, even a minor disruption can halt operations, compromise hygiene standards, or damage sensitive equipment. Backflow prevention ensures continuity of water-dependent operations and reduces the likelihood of costly emergency remediation. Preventing these incidents forms a key part of commercial construction risk management.

Ensuring Compliance with Municipal Codes and Regulatory Standards

Building codes, plumbing ordinances, and water authority regulations require commercial properties to install and maintain approved backflow prevention devices. Non-compliance can lead to penalties, termination of water service, and liability exposure. Routine certification and annual inspections are mandated in most jurisdictions, making backflow prevention not only a technical necessity but also a legal obligation for property owners and facility managers.

Reducing Liability Exposure and Public Health Risks

A single contamination incident can result in significant liability claims, especially when employees, tenants, or customers are affected. Commercial properties often house chemicals, fertilizers, fuels, and industrial byproducts that pose high contamination risks if introduced into the potable supply. Proper backflow prevention safeguards against cross-connection failures, reducing potential public health hazards and limiting legal and financial exposure. 

Extending Lifespan of Plumbing and Mechanical Systems

Contaminants entering the distribution network can corrode piping, damage valves, and compromise mechanical equipment such as water heaters, cooling towers, and boilers. By preventing backflow, properties maintain cleaner internal systems, improve equipment performance, and extend long-term infrastructure reliability.

Frequently Asked Questions 

Which types of commercial properties are required to install backflow prevention assemblies?

Properties with high-risk systems such as fire sprinkler mains, irrigation systems, elevated storage tanks, boiler feed systems, beverage dispensers, laboratories, commercial kitchens, and multi-tenant buildings often fall under regulatory requirements for commercial backflow prevention.

What classifications of backflow prevention assemblies are commonly used in commercial settings?

Typical devices include air gaps, atmospheric vacuum breakers, pressure vacuum breakers, double-check valve assemblies (DCVA), and reduced-pressure principle assemblies (RPZA), depending on the hazard level and regulatory requirements.

What happens if a backflow prevention assembly fails its certification test?

If the device fails testing, it must be repaired or replaced, retested by a certified tester, and the result reported to the authority. Failure to comply can result in fines, service termination, or disconnection of the water supply.

Can backflow incidents be prevented with regular facility audits?

Yes. Annual water system audits, cross-connection surveys, and preventive maintenance programs significantly reduce the risk of unseen vulnerabilities, especially in older or multi-wing commercial facilities.

Commercial-gas piping systems are engineered for reliability, but in real life, even well-designed systems often run into trouble. According to the Pipeline and Hazardous Materials Safety Administration (PHMSA), over the period 1998–2020, roughly 18 % of “significant” pipeline incidents (those causing injury, fatality, or major property damage) were due to corrosion. Other major contributors include material defects, improper installation, aging pipe segments, and external forces like construction damage or ground movement, which is common in commercial settings. These failures often appear as leaks, ruptures, or deterioration in welds and pipe materials. 

In this blog, we’ll examine these most frequent failure modes in commercial gas piping and share practical strategies that operators and facility managers can adopt to prevent leaks and hazards before they occur.

Common Failures &  Their Reasons in Commercial Gas Piping Systems 

Corrosion

Reasons:

• Black Steel Oxidation: Black iron (common in U.S. commercial gas systems) corrodes internally when exposed to moisture or hydrogen sulfide.
• Soil Corrosion (Underground): U.S. codes require corrosion protection for buried metallic lines (NFPA 54 §7.1.5); failures often occur when:
  • Protective wrapping deteriorates
  • Soil is highly acidic or poorly drained
  • Cathodic protection is missing or damaged
• Kitchen Environments: High humidity, salt, and cleaning chemicals accelerate corrosion around commercial cooking equipment.

Mechanical Joint Leaks (Threaded, Flanged, Welded)

Reasons:

According to FM Global loss data, joint leakage is one of the highest-frequency failure sources.

• Improper Assembly: NFPA 54 requires proper thread sealants; failures occur when commercial gas pipe installation is done correctly:
  • Non-approved sealants are used
  • Threads are overtightened or undertightened
• Vibration: Rooftop units, commercial dryers, generators, and high-capacity appliances impart vibration that loosens joints.
• Thermal Cycling: Gas lines connected to commercial appliances experience large temperature variations, causing expansion/contraction stresses.

Regulator Malfunction

Reasons:

• Regulator Vent Blockage: A known failure for commercial gas lines cited in NFPA 54 Annex G.
  Caused by:
  • Insects (mud daubers, wasps)
  • Construction debris
  • Snow or ice
• Incorrect Orientation: Many U.S. regulator models require upright commercial gas pipe installation for proper venting.
• Diaphragm Aging: Over time, rubber diaphragms lose elasticity, especially in high-temperature mechanical rooms.

Incorrect Pipe Sizing 

Reasons:

• Failure to Recalculate Demand: NFPA 54 requires sizing based on cumulative BTU load; many failures stem from adding new appliances without reassessing system capacity.
• Underestimating Pressure Loss: Especially in:
  • Large warehouses
  • Restaurants with multiple appliances
  • Long rooftop gas runs
• Mixing Pressure Zones: Combining low-pressure (≤14 in. w.c.) and medium-pressure lines without proper regulators. Incorrect sizing affects both natural gas and propane supply lines, which have different pressure requirements.

Material Fatigue & Stress Cracking

Reasons:

• Unsupported Piping: NFPA 54 specifies support spacing; improper supports cause sagging and stress.
• Building Shifts & Seismic Movement:
  States like California, Washington, and Utah require seismic gas shutoff valves due to common movement-related failures that directly impact commercial gas system pipes’ roles.
• Thermal Stress: High-output appliances heat nearby piping beyond design assumptions.

Flexible Connector Failures

Reasons:

• Kinking During Appliance Movement: Common in kitchens where equipment is moved to clean behind units.
• Over-bending commercial gas piping past manufacturer limits
• Connector Fatigue: Especially in older brass or stainless-steel corrugated connectors.
• Not using ANSI Z21.69 certified connectors

Damage from Other Building Trades

OSHA accident investigations frequently cite secondary construction activity as a cause of gas line compromise.

Reasons:

• Accidental Penetration: Drill bits, screws, or nails used during renovations.
• HVAC Retrofits: Rooftop work sometimes damages adjacent gas piping.
• Unsupported Spacer Removal: Contractors sometimes remove temporary supports, leaving piping stressed.

Faulty Valves & Safety Shutoff Devices

Reasons:

• Valve Wear: Frequently cycled valves (e.g., in commercial kitchens or mechanical rooms) wear internally.
• Incorrect Valve Ratings: Using valves not rated per ANSI B16.33 or B16.38 for gas service.
• Failure of Excess Flow Valves: EVFs mis-sized too small or too large won’t trip properly.

Testing, Commissioning, or Maintenance Deficiencies

Reasons:

• Improper Pressure Testing: Using air at pressures that exceed allowable test limits can damage components.
• Skipping Periodic Inspections: Many U.S. states do not mandate commercial gas line re-inspections, causing long-term degradation to go unnoticed.
• Inadequate Documentation: Missing as-built drawings make troubleshooting and compliance difficult. This complicates the key elements involved in commercial gas systems repair, slowing diagnosis and increasing risk.

How to Prevent Gas Piping System Failures 

Use Code-Compliant Materials and Certified Components

Preventing failures in commercial gas piping systems begins with using materials that fully comply with U.S. standards such as NFPA 54, the International Fuel Gas Code (IFGC), and relevant ANSI certifications. These codes require that all components, including piping, valves, regulators, and connectors, be listed and tested for fuel gas applications. Using non-listed materials not only increases leak risk but also violates mandatory U.S. safety regulations.

Implement Robust Corrosion Prevention Measures

To prevent corrosion-related failures, systems must incorporate proper protective coatings, approved wrapping for underground metallic pipe, and corrosion-resistant materials where applicable. Consistent monitoring for rust, discoloration, and moisture accumulation further strengthens long-term system integrity and safety.

Ensure Adequate Support, Anchoring, and Seismic Stability

Proper mechanical support is essential to preventing stress fractures and joint failures. U.S. codes specify the required spacing and type of pipe supports needed to maintain the stability of fuel gas systems under normal and extreme conditions. In seismic regions, additional bracing and seismic shutoff valves are required to protect gas systems from building movement. Ensuring that piping is properly anchored and protected against vibration and shifting helps prevent mechanical strain from developing into hazardous leaks.

Maintain Clear and Proper Venting of Gas Regulators

NFPA 54 requires that regulator vents be positioned, screened, and protected according to manufacturer specifications to avoid internal malfunction. Regular professional inspections help identify debris or environmental conditions that may compromise venting performance, thereby preventing over-pressurization incidents that can damage downstream components.

Schedule Regular Professional Inspections and Maintenance

A significant number of gas system failures occur in buildings that don’t receive routine professional inspections. That’s why it’s essential to bring in qualified technicians for regular assessment and maintenance. Today, IoT-enabled sensors are transforming how commercial utilities are monitored. These systems include real-time leak detection, pressure tracking, predictive maintenance, and automated shutoffs. IoT’s impact on monitoring and controlling commercial utility is that it now offers smarter, faster, and more reliable protection for commercial gas infrastructure.

Reassess Gas Load and System Capacity After Any Equipment Changes

Commercial buildings frequently add or upgrade gas-fired equipment such as boilers, dryers, fryers, and rooftop HVAC units. When the piping or regulators are not properly sized for these new loads, the system can experience unstable pressures, reduced appliance performance, and unnecessary mechanical stress. To prevent this, gas demand should be recalculated whenever equipment changes occur, using NFPA 54 sizing criteria. Regular reassessment ensures the system stays balanced, efficient, and capable of supporting both current and future appliance needs.

When excavation is done improperly, costly issues inevitably follow. This blog outlines why this early stage is critical and what a properly executed excavation process should include.

Foundation cracks, soil movement, and drainage failures rarely appear out of nowhere; they almost always originate from mistakes made before the first footing is even poured. That first phase is excavation, and it determines whether the entire structure will perform as intended or struggle against avoidable issues. 

When excavation is rushed, poorly planned, or executed without proper geotechnical insight, the building begins to reveal its consequences, leading to costly structural corrections later. This is why understanding the role of proper excavation in building construction is essential. 

In this blog, we uncover what makes commercial excavation so critical, the risks that arise when it’s done poorly, and the key steps that set a commercial project up for long-term stability and success.

Why Proper Commercial Excavation Matters?

1. Establishes Long-Term Structural Safety

Proper excavation prepares the ground by identifying and removing weak soils, organic layers, and hidden debris that could compromise stability. By replacing these materials with compact, engineered fill, the site gains uniform strength capable of supporting heavy commercial loads. This prevents uneven settling, structural misalignment, cracks, and other long-term building failures, ensuring the entire structure rests on a reliable and durable foundation.

2. Sets Accurate Elevations 

It determines the precise depths and heights for foundations, parking areas, drainage slopes, and utility routing, with correct slopes, levels, and transitions. Even a slight elevation error can alter how the entire site functions. If incorrect grading causes water to drain toward the building instead of away from it, you end up with foundation stress, moisture intrusion, and recurring site maintenance problems. 

3. For Proper Drainage and Water Management

A well-executed commercial excavation plan shapes the land so water moves predictably and safely across the site. This helps prevent water accumulation, erosion, and hydrostatic pressure against foundation walls. When water consistently pools near structural elements, it doesn’t just create surface issues; it slowly weakens the foundation system from the outside in.

4. Ensures Safe and Accurate Utility Installation

Utility trenches require exact depths, slopes, and compaction to protect pipelines and conduits. Poor commercial excavation can cause lines to shift, break, or become misaligned, problems that often surface only after the building is occupied. And once utilities fail underground, repairs require excavation through finished spaces, parking lots, or landscaped areas. Read this blog to get a deeper understanding of why underground utility installation is crucial.

5. Ensures Compliance With Engineering Standards

Commercial excavation must meet strict geotechnical and safety requirements. Incorrect compaction, improper fill, or non-compliant trench slopes quickly trigger inspection failures. And if a site doesn’t pass inspection, work stops immediately. Re-excavation, retesting, and engineering revisions add significant cost and delay.

6. Proper Integration of Retaining Walls and Site Structures

Retaining walls in commercial sites carry significant lateral soil pressure, especially on sloped or multi-level properties. Proper excavation ensures the footing is dug to the correct depth and width so the wall can handle the structural load without shifting. It also prepares the surrounding soil to support the wall at the right angle, preventing collapse or movement over time. 

Key Steps for Successful Excavation in Commercial Projects

1. Perform a Full Pre-Construction Site Analysis

Before breaking ground, commercial projects require detailed geotechnical studies, soil testing, utility mapping, and environmental assessments. It ensures the ground can support large structures, prevents unexpected utility conflicts, and establishes the safest strategy for commercial excavation.

2. Create a Precise Excavation Blueprint

A well-defined plan outlines excavation depth, cut-and-fill needs, grading slopes, equipment requirements, and the sequence of operations. This step aligns the excavation in building construction with structural design requirements and minimizes the risk of foundation discrepancies or schedule overruns.

3. Stabilize and Prepare the Soil Correctly

Commercial foundations depend on load-bearing soil. Proper compaction, moisture control, and soil stabilization help prevent settlement, shifting, or structural cracks later. Strong soil preparation ensures the building has a durable base from day one.

4. Implement Strong Safety Measures and Compliance Protocols

These commercial sites involve heavy machinery, large crews, and strict timelines. Ensuring OSHA compliance, trench safety, slope protection, and traffic control reduces accident risks and maintains regulatory approval throughout the commercial excavation phase.

5. Establish Reliable Drainage and Water Management Systems

Proper drainage planning, including grading, trenching, and stormwater routing, is essential. Inadequate drainage can cause erosion, pooling, or foundation damage, all of which pose long-term risks to commercial structures.

6. Maintain Clear Coordination With All Project Stakeholders

Excavation impacts every downstream trade. Close collaboration with commercial utility contractors, architects, engineers, and general contractors ensures each phase aligns with structural requirements, avoids rework, and keeps the project moving efficiently.

Finishing Thoughts 

Proper commercial excavation is fundamental to commercially sound construction. When done right, it lays a durable, code-compliant foundation that supports building longevity and reduces long-term maintenance costs.

Common Questions About Commercial Excavation

How early should excavation planning begin in a commercial project?

Planning typically begins months before equipment arrives on-site. Excavation in building construction depends heavily on geotechnical data, environmental clearances, and utility coordination, so early planning helps prevent delays and redesigns during construction.

How long does excavation usually take for a commercial project?

Timelines vary by project size, soil condition, weather, and permitting. Small commercial pads may take days, while large multi-story foundations can require several weeks of phased excavation and soil preparation.

How does excavation affect sustainability goals in commercial construction?

Sustainable sites require optimized grading, controlled soil erosion, and minimal material waste. Commercial excavation teams now use recycled fill, erosion-control systems, and low-impact equipment to meet green building and ESG requirements.

Can excavation failures affect commercial insurance or project approvals?

Absolutely. Structural failure linked to poor commercial excavation can void warranties, increase insurance premiums, and lead to regulatory shutdowns. Insurers now demand documented proof of proper soil compaction and excavation methods.[/fusion_text][fusion_code render_logics=””]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[/fusion_code][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]
