The multi-block nature of the project enabled the developer to construct the Brewery Block buildings simultaneously and take advantage of related efficiencies. For example, minimizing duplication among construction crews, deliveries and staging substantially reduced the amount of time, energy and transportation going into the project.
A minimum of 20% of all materials used came from local and regional sources. This includes materials such as concrete, masonry, paints and wood products, among others. Products and materials with high amounts of recycled content were of priority and utilized whenever feasible. Over 25% of all construction material used in the project contains recycled content.
The project successfully recycled 96 percent of construction waste because an aggressive commingling recycling program and tracking system was established prior to construction. Construction Project Manger Kevin Cady notes that putting the plan into practice required that the information trickle down to the subcontractors. “You have to inform them and pull them along…ultimately it’s up to the general contractor to ensure that objectives are realized”. Typically, the general contractor is responsible for tracking C&D waste recycling and gathering the necessary documentation from the subcontractors to earn the relevant LEED credit. In addition, over 94% of all demolition waste was sorted, salvaged and recycled during the process of decommissioning the old Brewery complex.
An indoor air quality (IAQ) management plan was implemented during construction to prevent contamination of the building’s HVAC system. This entailed up-front planning for sequencing materials installation among other efforts and will earn the LEED IAQ credit.
A sustainability/LEED consultant was engaged after the design process to structure a LEED program for the developer. LEED had been used as a framework to inform the design but a consultant was necessary to properly manage the LEED process. Project consultant Scott Lewis notes, “The project team has pressing time demands and if nobody has the responsibility of tracking the project it all falls off of the table. It’s not a priority for them, it’s an added duty.”
Building commissioning of all mechanical and electrical systems was employed throughout the project to not only satisfy LEED points but also to ensure that the building systems operate at peak efficiency. In general, Senior project manager Dennis Wilde points out that “Our construction schedule was never impacted by any of the green features…this is not an issue if it’s addressed up front.”

Keys to Success – Construction:
  • Contract with a local salvage materials firm to perform a pre-demolition salvage
  • Plan and schedule construction activities to minimize duplication among construction crews, deliveries, and staging
  • Integrate preferences for local and regional materials and materials containing recycled content into the specifications
  • Establish an aggressive commingling recycling program and tracking system prior to construction
  • Communicate sustainability objectives and responsibilities to all subcontractors prior to construction
  • Design an indoor environmental quality management plan prior to construction
  • Engage a LEED accredited professional consultant to structure a LEED program for the project
  • Commission all mechanical and electrical systems during, and after, construction
