DGS New Natural Resources Building

The 21-story office building on P Street in Sacramento was a design-build project for the California Department of General Services (DGS). The building was designed to host about 3,450 employees from eight state agencies.

With Glumac Engineering, Terrapin co-facilitated an Integrative Design Opportunities Charrette to build upon design and performance goals established both by the client and design team during the concept proposal phase. The process evolved a menu of creative design solutions for supporting the client’s mission “to restore, protect and manage the state’s natural, historical and cultural resources”.

During the 1.5-day charrette, Terrapin facilitated deep-dive discussions on sustainability strategies, while the engineer guided the team through considerations relative to LEED performance compliance and scheduling. Opportunities to incorporate innovative, passive strategies, and high-performance technologies were assessed to further systems integration for energy performance and optimization of water efficiency, indoor environmental quality, and pre- and post-consumer waste reduction. The charrette also helped identify opportunities for optimizing occupant socialization, comfort, and health and wellbeing, none of which would have been as successful without the participation of a diversity of stakeholders so early in the design-build process.

To ensure the expectations and opportunities formed during the charrette were upheld through the design-build process, Terrapin facilitated three interdisciplinary focus groups – for building energy systems, water systems, and health and wellbeing. For each group, Terrapin guided a series of strategy sessions to explore how these three topics informed building and site design decisions. Analyses were used to inform the owner’s project requirements (OPR), basis of design (BOD), design and construction documents, and a Basis of Operations (BOO).

Terrapin conducted peer reviews of the project’s design plans at three stages in the design process to ensure that the integrative design strategies, the Biophilic Design Plan, and the LEED design and construction requirements were being upheld throughout the design process. Design plan reviews were scheduled early in each phase of the project to ensure strategies had the greatest potential feasibility and efficacy.

Terrapin’s final task was to prepare the Biophilic Design Plan for submission in the LEED pilot credit. The Biophilic Design Plan influenced all aspects of the building experience, from building entry and workstation design, to placement of vertical transit, to landscape priorities.
