• Scaffold Resource at the Chapman Mill

    Historical restorations are more complex than new construction projects. During a historical project, you have to take care not to use techniques that could damage the space you’re trying to restore. As such, things like scaffolding and shoring have to be used carefully, in order to preserve the space. At Scaffold Resource, we are experienced in this kind of construction work and have assisted on many jobs that involve this delicate balance of new building and historical preservation. The Chapman Mill is one such project in which we have been involved.


    The Chapman Mill is a former grist mill in Northern Virginia that was built in 1742 and was once the tallest stacked stone building in the country. The process of restoring it as a historical site after it was damaged by a fire was complicated due to the unexcavated worksite that was infested with snakes and the structural damage caused by the fire. We assisted with appropriate scaffolding necessary for safe working conditions without causing further damage to the site.


    From historical restorations to new construction, Scaffold Resource is available to assist in a variety of projects. Learn more about our engineering and project consultation services or scaffolding in Washington, D.C., by calling (301) 924-7223.

  • The Methods of Wall Bracing

    Wall bracing is performed during construction on wood-frame buildings in order to make the structures less susceptible to wind damage. This practice is especially important in areas in which high-wind storms, such as hurricanes, are possible. In those regions, there are likely to be local building guidelines that stipulate the minimum level of wall bracing that is required in construction projects. In other cases, the guidelines set by the International Residential Code are used. There are several different methods of wall bracing that are used, depending on the needs of the project. Scaffold Resource can assist with wall bracing calculations as part of our engineering consultation services. Here is a look at some of the common processes.


    Engineered Shear Walls

    For wind loads that are expected to reach or exceed 110 miles per hour, engineered shear walls may be used. In this process, an engineer calculates the expected wind loads to determine where shear walls should be located and what their size and construction should be. Shear walls have hold-downs at every segment. These segments may be as small as 27 1/2 inches, depending on the anticipated wind loads.


    Method 3

    Method 3 is so called because it adheres to the IRC’s Method 3 guidelines. It is used when wind loads are expected to be less than 110 miles per hour. With this method plywood, or in some cases, OSB, is attached to strategically chosen areas of walls to brace them against the wind. The attached plywood or OSB must cover the full height of the wall and be at least four feet wide.


    Fully Sheathed

    Fully sheathed buildings are completely covered in plywood or OSB. In these cases, IRC guidelines allow for fewer areas of the walls to be braced. With this method, however, all corners of the building have to be braced wall panels.

  • A Look at Safety Measures Taken During the Golden Gate Bridge Construction

    Bridge construction involves risk, but the Golden Gate Bridge set a new standard for safe construction practices. Any construction project that involves working at height on scaffolding should incorporate the tightest possible safety measures, and the Golden Gate Bridge construction project set an example that is still relevant today.


    Watch this video to learn more about safety procedures followed during construction of the Golden Gate Bridge. This dangerous project had a remarkable safety record, thanks to the efforts of the forward-thinking site manager.

  • The Death of an Excavation Worker: A Case Study in Safety Violations in California

    Working in construction requires the utmost attention to safety. Anything less isn’t just risky—it can be deadly. In California, two recent incidents demonstrate how true that is. Two construction company workers were killed on the job in separate incidents that are tied together by one thing: a lack of proper safety protocols on the site. At Scaffold Resource, we help contractors ensure that their workers are safe with project consultation services. We can help you review your safety protocols and help you make sure you are following appropriate procedures when using scaffolding, shoring, and more. Here is a look at both incidents and how they occurred.


    Bay Construction Co.

    Bay Construction Co. was working on an underground pump station in Oakland. They assembled a trench box to complete the work, and while a worker was still inside the trench, they began removing the shoring system that was supporting it. The pipes that were used in the shoring included linear rails that weighed 5,000 pounds, and the excavator that was being used to remove the rails was not strong enough to carry that amount of weight. The excavator failed and a 5,000 rail was dropped on a worker inside the trench, killing him. OSHA guidelines prohibit shoring systems from being installed or removed when anyone is inside the trench. Bay Construction Co. was issued nine separate citations and was charged more than $140,000 in penalties.


    Empire Equipment Services

    Empire Equipment Services was working on a sewer pipe installation project that involved a trench that was 17 feet deep. Before the work began, the soil was not graded, which is required in order to determine if a shoring system is needed. The soil was not stable, but no shoring was used. Further, the soil was not sloped appropriately. As a result, a 30-foot wide section of soil collapsed during the project, trapping and filling a worker inside the trench. The company was fined $66,000.
