La Asociaci\u00f3n de Hormig\u00f3n Tilt-Up (TCA)<\/a> \u2013 a non-profit international organization that serves to expand and improve the use of tilt-up as the preferred building system \u2013 has released a position statement assigning responsibility for the assessment of floor slab capacity for the bracing of tilt-up panels.<\/p>\n The statement is intended to provide clarity and direction on an important \u2013 and currently under-addressed \u2013 area of jobsite safety. The Occupational Safety and Health Administration (OSHA) requires that tilt-up concrete panels be temporarily braced to prevent panels from overturning or collapsing during the construction of a tilt-up structure (Title 29, Code of Federal Regulations, Standard 1926.704<\/a>) However, OSHA does not specify how to prevent tilt-up wall panels from overturning or collapsing. While the TCA previously developed a temporary bracing guideline for use by the tilt-up construction industry that addresses the parameters by which the bracing scheme should be designed, the guideline does not assign responsibility. The supplementary statement now released by the TCA is as follows:<\/p>\n The Owner\u2019s designated representative for construction shall be responsible for assigning a qualified firm to review the floor slab capacity for the bracing of the tilt-up panels in accordance to the latest edition of the TCA bracing guidelines.<\/b><\/p>\n<\/blockquote>\n \u201cThis discussion has been going on within the industry for years,\u201d said Barclay Gebel, Chair of the TCA Safety Committee. \u201cYou get into these situations where everyone starts pointing fingers and balls get dropped.\u201d<\/p>\n Because tilt-up construction is a rapidly developing industry, engineering and jobsite practices must continue to adapt.<\/p>\n \u201cThe TCA is composed of architects, engineers, contractors, developers and suppliers. We are uniquely equipped to address these types of issues,\u201d said Mitch Bloomquist, Managing Director for the TCA. \u201cWe often stress that tilt-up is a system<\/i>; therefore, design\/construction decisions have implications across the board. The greatest efficiencies are realized with this in mind. More important, the project is safest with this in mind before, during and after construction.\u201d<\/p>\n It is widely accepted that the engineer performing the lifting and bracing design is responsible for the sizing, placement and connection of the braces. However, the design of the concrete slab (to which the braces are anchored) to accept these temporary loads does not fall under specific ownership. Tilt-up wall panels continue to be designed taller and wider than ever before, so the surface area per wall panel for accepting wind pressure also grows and this makes temporary brace forces larger. These issues are further exacerbated at corner conditions where braces from multiple panels share slab space.<\/p>\n \u201cThere are many variables to consider when reviewing slab thickness design for bracing,\u201d said Matthew Bell, P.E., P. Eng., Chair of the TCA Technical Committee. \u201cOne must consider joint locations, fill-in slab areas and in general the available slab which can be accounted for to resist brace forces.\u201d<\/p>\n \u201cEvery project is unique,\u201d said Gebel. \u201cThe point is simply that it needs addressing. It\u2019s imperative to identify who is responsible for this issue so that it is addressed properly. It is a matter of life safety and nothing could possibly be more critical.\u201d<\/p>\n The TCA Guideline for Temporary Wind Bracing of Tilt-Up Concrete Panels During Construction can be purchased online at www.tilt-up.org\/resources<\/a>.<\/p>","protected":false},"excerpt":{"rendered":"\n
