G/BA commissioned the direct digital control (DDC) system for all six projects which included 155,000 square feet of building additions with 29 new air handlers, 18 new chillers and 8 new diesel generators and totalled 3,700 control points. G/BA was also the mechanical, electrical and controls design engineer on all six projects,

• Prepared design documents for mechanical and electrical systems.
• Prepared commissioning specification, including prefunctional checklists, control system functional performance testing (including trend logs) and contractor requirements for O&M manual development and Owner training.
• Reviewed and approved shop drawings including hardware and software; sequences of operation including power failure, DDC system failure and fail-safe/back-up modes of operation; wiring diagrams; panel configurations; communication bus riser diagrams; field interface equipment; DDC system redundancy configuration; central operator workstation hardware and software including graphic user interface screens (floor plans, system flow diagrams); control loop control/alarm setpoints and portable operator interface equipment.
• Reviewed and approved completed prefunctional checklists and trend logs prior to functional performance testing.
• Completed functional performance testing of every input/output point, encompassing all the newly provided equipment and additional chiller plants, air handlers and terminal devices (air and water) associated with the existing building space.
• Coordinated controls contractor training of Owner’s operations staff. Training included three phases: 1) classroom training, 2) on-site training with installed systems, and 3) follow-up training approximately one month after functional performance testing was completed.
• Developed O&M manuals for all mechanical and electrical systems and reviewed control system O&M manuals prepared by the contractor. Reviewed and spot-checked as-built documents prepared by control system contractor.
