Trenching and shoring play important roles in many construction projects, but as with most things on a jobsite, they come with some safety hazards. Understanding these hazards and taking steps to reduce them will increase the safety of your workers and help to ensure projects are completed on time and without injury or damage. Here is a closer look at some of the hazards that can make trenching and shoring dangerous and what you can do to control them.
Equipment falling into an area of trenching and shoring is a common concern on jobsites. Start by making sure that employees are out of the trench whenever there is digging or when items are being raised out of or lowered into the trench. Keep a perimeter area around the shoring and trenching that is kept clear. Workers who are inside the trenching should always wear hard hats and should never work under raised loads.
Employees who are working in areas of trenching and shoring must have clean and clear air to breathe. Never allow employees to work in an area with oxygen levels less than 19.5% or more than 23.5% or a combustible gas concentration of more than 20% of the lowest flammable limit. If you are working with hazardous substances, check the threshold limit values for those substances. The atmosphere should be checked regularly.
Ingress and Egress
Workers must have a clear way in and out of the work area. If the trenching that is being used is four feet deep or more, then the egress must be fixed. Workers should never be more than 25 lateral feet from the closest egress at any point while working. Ladders must be secured and should raise at least 36 inches from the top of the trenching.

Construction projects frequently fall behind schedule. Unfortunately, the impacts can be extreme for everyone involved. The construction team faces extra expense that is not in the budget for work hours, scaffold rentals, and other costs associated with a lengthier-than-projected schedule. The customer who commissioned the construction faces inconveniences associated with delayed access to the finished work. Despite these issues, behind-schedule projects are extremely common. What causes these kinds of delays, and is there anything your team can do to reduce the chances of them happening? Here is what you need to know.
Common Causes of Construction Delays
Any number of factors can lead to delays in construction project, and some of the causes are not predictable. However, there are some causes of timeline problems that occur more frequently than others. Some of these common causes of delays include:
- Bad weather
- Delays by subcontractors
- Bureaucracy delays that slow down permitting approvals
- Changes made to the project plan
- Budgeting issues
- Shortages of materials
These factors can all cause delays of different lengths on a construction project. In most cases, these issues are not caused by the construction team, but mitigating the impact of the delays does rely on the onsite construction crew. For this reason, the construction team must do what it can to reduce these causes of delays from being an issue.
Strategies for Reducing Delays
Some causes of delays are out of anyone’s hands. For example, you can’t control the weather, and there is little you can do if the weather is preventing work from occurring. Other factors can be managed. Some strategies to consider include:
- Don’t work with vendors or subcontractors who are frequently behind schedule
- Have clear project plans agreed upon up-front to avoid late changes
- Build in extra time when you’re ordering materials or applying for permits to account for delays
It is also helpful to be conservative when projecting a timeline, so you have some wiggle room if an issue develops.

During our many years in business, Scaffold Resource has had the honor to work on some of the nation’s most beloved landmarks. But none of that work is as important as the steps we took to safeguard America’s true national treasures: its children. Our shoring erection project at Brent Wood Elementary was particularly challenging because the school was in operation at the time. Ensuring the safety of each and every child on campus was our top priority on this job.
There were other challenges regarding this project’s shoring erection. Namely, that we didn’t have reliable “as built” drawings available, and so our workers had to conduct a full evaluation of the existing old structure. Our engineers designed a cantilevered shoring system that turned certain elements of the building into counterweights.
Scaffold Resource is available to provide shoring erection, sidewalk canopies, and scaffolding rentals at your construction site in Washington, D.C. Call our office at (301) 924-7223 to discuss your needs.
Every worker has the right to a safe workplace. In the U.S., these rights are protected by numerous laws and regulating bodies, including the Occupational Safety and Health Administration (OSHA). Although safety issues are relevant in every workplace, some workplaces pose more of a threat than others. Workers setting up tube and clamp scaffolding or participating in shoring erection need to be particularly cautious about safety concerns.
You can learn more about workplace safety rights when you watch the accompanying video. It explains that workers have the right to ask questions if anything seems unsafe, and to report job-related injuries without fear of retaliation.
Scaffold Resource in Washington, D.C. is known for our superior track record of safety, and we work hard to keep it that way. Our workers perform daily hazard analysis on every job, and participate in many other rigorous safety initiatives. Call (301) 924-7223.
The Occupational Safety and Health Act (OSHA) requires employers to properly train workers to recognize, address, and prevent hazardous conditions. Specific safety training requirements have been developed for various roles within the construction industry, including work performed on scaffolding. Abiding by these training requirements can save lives and reduce the risk of serious, disabling injuries.
Safety Training Requirements for Working on Scaffolding
OSHA’s scaffolding training requirements are divided into three categories: Requirements for employees working on scaffolding, those working with scaffolding, and employees in need of retraining. All training must be performed by a person who is qualified in hazard recognition and control as they pertain to the specific type of scaffolding being used. Employees who perform work while on scaffolding must receive safety training in these areas:
- Recognizing electrical hazards
- Using best practices to deal with electrical hazards
- Recognizing fall hazards and falling object hazards in the work area
- Using the scaffolding properly
- Handling materials properly while on the scaffold
- Recognizing the maximum intended load
- Recognizing the load-carrying capacities of the scaffold
- Erecting, maintaining, and disassembling fall protection systems and falling object protection systems
Safety Training Requirements for Working with Scaffolding
A qualified person must administer safety training to every employee who is involved with these scaffolding-related activities:
These employees must receive safety training in these areas:
- Understanding the nature of scaffold hazards
- Understanding correct procedures for all scaffold-related activities
- Design criteria, intended use, and intended load-carrying capacity of scaffolding
Retraining Requirements to Regain Requisite Proficiency
Safety training in the construction field is an ongoing endeavor. Whenever there is reason to believe that an employee no longer has the skill or understanding to perform work safely, that employee must be retrained. Retraining is a requirement for the following situations, but is not limited to them:
- When new hazards are present at the worksite and the employee lacks training in them
- When changes in scaffolding and other equipment present a new hazard that the employee lacks training in
- When substandard work indicates the employee has lost skill or understanding
At Scaffold Resource, we firmly believe that safety is everything, and this is evidenced by the numerous and ongoing safety training initiatives our workers undergo every day. Scaffold Resource in Washington, D.C. can also custom-design safety training programs for your company, including as-needed specialized training and monthly scaffold hazard awareness training. Company representatives can inquire about our training capabilities at (301) 924-7223.
All construction operations carry inherent risks, but excavations are widely recognized as being among the most dangerous. Cave-ins and trench collapses pose a grave threat to worker safety, as they cause fatalities and injuries every year. The erection of the proper shoring keeps workers safe. Engineers must assess the type of soil in the area before they can determine the proper method for building shoring.
Identifying Stable Rock
The Occupational Safety and Health Administration (OSHA) recognizes four categories of soil and rock deposits. The first is stable rock, such as granite or sandstone. Solid rock can be safely excavated with vertical sides, as it will remain intact. However, before classifying a deposit as solid rock, the engineer must determine whether the rock contains cracks.
Identifying Type A Soil
Type A soils are typically clay, clay loam, and silty clay. These are cohesive soils that feature an unconfined compressive strength of 1.5 tons per square foot or greater. Note that no soil may be classified as type A if any of the following are applicable:
- It’s part of a sloped, layered system
- It’s been previously disturbed
- It’s fissured
- It’s been subjected to vibrations
- It has seeping water
Identifying Type B Soil
Type B soils are also cohesive soils. Typical examples include angular gravel, silt loam, silt, and dry, unstable rock. Type B soils have an unconfined compressive strength between 0.5 and 1.5 tons per square foot. It’s also possible for a soil to be classified as type B if it’s been subjected to vibrations or fissures, but would otherwise be classified as type A soil.
Identifying Type C Soil
Some examples of type C soils are gravel, sand, submerged soil, loamy sand, soil with seeping water, and unstable, submerged rock. On construction sites, it’s most common for deposits to be classified as type C. These cohesive soils have an unconfined compressive strength of less than 0.5 tons per square foot.

Workplace safety must be a top priority for construction companies. There are inherent risks involved with major projects like shoring erection and scaffolding work, and one of those risks is the possibility of head injuries. All employees should wear hard hats whenever there is a potential for falling objects, accidental head contact with electrical hazards, or contact between a fixed object and an employee’s head.
This video offers a simple demonstration of why hard hats are so important. “Melanie,” a watermelon, is wearing a hard hat the first time a brick falls on her. As you can see, there is no cranial damage. The second time the brick falls on Melanie, she lacks a hard hat, and the damage is considerable.

Jobsite accidents like collapsed walls are every construction manager’s worst nightmare. Even if the accident occurs during off-hours when no employees are present, a collapsed wall can easily lead to major headaches, including construction delays and higher insurance premiums. Only a strict adherence to OSHA regulations and industry standards regarding wall bracing safety can prevent this type of accident from happening in almost any circumstance.
Understanding the OSHA Regulations and Industry Standards
The OSHA regulations are uncharacteristically minimalist regarding wall bracing safety. The main code requirement is that all masonry walls taller than eight feet must be adequately braced until the permanent supporting structures are installed. Because the official regulations can be subject to interpretation, the Mason Contractors Association of America (MCAA) developed its own industry standards. This resulted in the widely accepted and used Standard Practice for Bracing Masonry Walls under Construction guidelines. Mason contractors and project managers are strongly encouraged to follow the Standard Practice and consult its tables regarding the proper installation of bracing.
Establishing the Restricted Zone
One of the first steps for proper wall bracing is to establish the restricted zone based on the wall’s height. The restricted zone should be on the side of the masonry wall opposite the scaffolding, if scaffolding is up. Once the scaffolding is removed, the foreman must establish the restricted zone on both sides of the wall. For the sake of simplicity, mason contractors can tape off the restricted zone based on the height the wall will be once it’s completed. Otherwise, the boundaries must be re-established as the wall grows higher.
Designing the Wall Bracing
For maximum protection from damaging winds, a minimum of two braces must be installed for each wall panel. Note that the national Building Codes prohibit a space greater than 25 feet between control joints. Finally, there must be 20% of the wall between any given brace and the nearest control joint.
