Bridging the Specification Gap between Divisions 03 and 09: Concrete and floorcovering associations unite

Division 03 specifies concrete floor surface flatness requirements to be installed by the concrete contractor. However, Division 09 specifies the concrete floor surface flatness for the flooring installer that must be met before installing the floorcovering. Cooperation between the American Society of Concrete Contractors (ASCC) and six flooring associations has led to a solution for bridging the specification gap between Divisions 03 and 09.

Enhancing Energy Performance with Balcony Thermal Breaks

This article examines how a building’s energy performance can be enhanced with structural thermal breaks for balcony connection. New engineered solutions can assist mid- and high-rise building project teams in complying with continuous insulation (ci) code requirements. These structural connections are especially important to address in multi-family specifications because thermal bridging for every residential unit in the structure can add up to significant heating and cooling loads.

Getting on Deck: High-performance options for composite decking

Since the late 1980s, manufacturers have introduced dozens of wood-plastic composite decking products, including composite boards with thin plastic caps (i.e. capped composites) in recent years. Composite decking manufacturing methods vary, resulting in deck boards with significantly different performance characteristics. Several composite brands have experienced field failures, but newly advanced products are proving promising against demanding exposures. Specifying durable and attractive composite decking requires attention to key physical traits, including moisture absorption, and insect resistance.

Specifying Steel Fibers for Concrete Floors

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.
