Focus on specialty structures: Codes and standards
Sports arenas, historical buildings, theaters and other specialty buildings require unique engineering design, especially codes and standards compliance

CSE: Please explain some of the codes, standards and guidelines you commonly use during the project’s design process. Which codes/standards should engineers be most aware of?
Hedman: Our firm designs systems for new and existing structures requiring the use of new construction and the existing building codes. Many engineers fail to reference the existing building code when working in an existing structure.
Lewis: All projects at our company are code compliant, regardless of the vertical market they are in. The most difficult codes to keep tabs on are the ever-changing environment and efficiency standards, which is an overall positive. Various jurisdictions are adopting and increasing the efficiency guidelines, which is a good thing for our industry to show the progressive nature of concern for the environment.
CSE: What are some best practices to ensure that such buildings meet and exceed codes and standards?
Hedman: Our company implements an inhouse quality control review for both design and construction review by engineers and dedicated construction administrators. The documents are reviewed for constructability, code compliance and engineering before the project being issued. In addition, many states and local jurisdictions require buildings illustrate commercial compliance using COMCheck software upon completion of construction documents. This check ensures the designed systems for new commercial buildings, additions or alterations meet the requirements of ASHRAE Standard 90.1 and the energy code.
CSE: How are codes, standards or guidelines for energy efficiency impacting the design of such projects?
Lewis: Guidelines for energy efficiency are driving innovation and creating a more cohesive approach throughout the design team from day one. Overall these changes are creating better projects that are more thought out and holistic. The balance to a more sustainable project is the overall first cost, which still matters. It’s easy to be highly sustainable when money isn’t a consideration but takes extra thought when the two work hand in hand.
CSE: What are some of the biggest challenges when considering code compliance and designing or working with existing buildings?
Hedman: Many existing buildings that our company is involved with are historic landmarks, historic sites or included as part of a historic district. The renovations and revisions to the envelopes and fenestration are often regulated by historic landmark commissions and limit the possibilities for changes to the envelope. As a result, the MEP systems must be designed to allow the entire building to meet the energy code, requiring these systems to exceed the minimum energy requirements.
Lewis: Existing buildings provide and additional code challenges, assuming that we are bringing all aspects up to the current codes. Available space — both in the building and on the roof — can be tight, which may limit solutions for compliance.
