Sustainable structures must balance the environmental footprint, service life, social aspects, and economic factors. As modern society shifts to a circular, carbon-neutral built environment, concrete continues to deliver ‘best-in-class’ performance as a building material.
The American Concrete Institute (ACI) published ACI 318-19, Building Code Requirements for Structural Concrete, in July. ACI 318 presents requirements for design and construction of structural concrete that are necessary to ensure public health and safety. It is addressed to the engineer or the building official who is responsible for the contract documents.
Vancouver-based Revery Architecture has designed Simon Fraser University’s (SFU’s) new state-of-the-art engineering building in Surrey, B.C. The academic research facility focuses on clean technology and sustainable energy solutions.
Specifying resinous flooring systems involves crunching numerous performance data points, such as compressive strength and abrasion resistance, to select the optimal flooring system for a given environment. A major goof in picking a system could mean years of lost durability.
Zero-lot-line-construction typically requires the application of blindside waterproofing to various types of shoring conditions. Some waterproofing consultants and professionals feel redundant waterproofing is the most effective method in these conditions.
The four-storey North Bay Courthouse building in Ontario was retrofitted with a new lateral force-resisting system (LFRS). The interior steel framing and slab connections were structurally strengthened to transfer seismic loading to 13 full-height, reinforced precast concrete shear walls around the building perimeter. Further, cracked masonry joints were repointed, damaged masonry units were replaced, and an elastomeric coating was applied over the entire wall surface.
