EPMA Member Haley gave us an inside look at how implementing LEED looks from the construction management side with her work on Boston College’s new stadium.

The facility is being built above a high-pressure water main which supplies water to Boston. The construction includes 212 pressure injected footings for the foundation, a storm trap system under the turf and 16 steel trusses roughly 200 feet tall. The steel erection lasted about 6 months and had a steep learning curve, the first truss erection taking significantly more time than the final erection. Water control is one of the most important factors because it is in a watershed area and the water main provides water to the city of Boston. There cannot be any heavy equipment running over the main and vibrations of construction must be monitored.

Embodied energy is a concern to Haley. The steel coming from Wisconsin and the precast panels coming from Toronto, the question of “how much energy and gas did we burn getting this stuff here?” is a legitimate one. A building’s embodied energy is typically very high.

A large part of ensuring that LEED standards are met on the construction site include making sure waste and recycling are properly managed and disposed of. This requires the CM to make sure the subs are doing things properly.

QAQC is important to ensure the building is airtight and the mechanical systems are able to create a comfortable environment for the end users. Passive house emphasizes the importance of a tight envelope. It is also important to supervise the construction to make sure the right materials are being installed correctly. EPD memos (that prove that a manufacturer’s goods are coming where they are said to) are a difficult document to obtain.
