The IBC is recognized as the model building code for commercial construction, which is then adopted by state and local jurisdictions. Through NFPA 285, increasing use of energy efficient continuous insulation (ci) and innovative wall assemblies places a greater emphasis on fire performance of exterior walls.
As buildings become more complex and connected, the demand for materials supporting high-performance facilities has also increased. This includes building controls, lighting, electrical and digital infrastructure, audio/visual (A/V), and other aspects of the structure.
As alternative methods of project delivery become more popular, it becomes clear that all specifications are not alike and one size does not fit all. In fact, there are a many important concepts that need to be carefully considered before design professionals prepare specifications for a design-build project.
Recent pressures have caused responsibility for many design solutions to be transferred to the constructor, as mentioned in Part 1 and Part 2 of this series. To properly complete deferred design, a solid understanding of regulations surrounding shop drawings, specifications, submittals, and other types of documentation is necessary.
