Discussing specification writing and documentation details can be challenging, but the right set of specifications is a key component in the process to deliver a successful project. It is crucial the specification writer understands the intent of how systems will operate and how systems relate to each other. This is getting even more important as new buildings are getting more complex and have loftier energy efficiency goals. This article describes the most important aspects of construction specifications to ensure a good outcome for energy efficient buildings.
Thin, short strands of steel are being increasingly specified as reinforcement in ground-supported slabs and in composite steel deck-slabs. Structural engineers are still figuring out how best to design with these components, but specifiers need to think about how to define this material in the contract documents. Dosage is critical, for one thing, but not all fibers are alike. Without specifying other key details, one can end up with concrete that contains the specified mass of fibers, but does not fulfill the designer’s intentions.
