Professional Services, Testing, Balancing, and Commissioning Services for Various Projects

Collin County, Texas, is soliciting professional services for Testing, Adjusting, and Balancing (TAB) and Building Commissioning (Cx) for various projects on an as-needed basis. Managed by the Construction and Projects department, these services ensure that public works and county-owned facilities meet design intent and state energy codes. The scope of work primarily covers base building systems, including HVAC, chilled water, condenser water, hot water, and HVAC control systems, with optional add-ons for electrical power distribution, lighting controls, fire alarms, security, and communication systems. Commissioning services must follow the ACG Commissioning Guideline and are executed across five phases: pre-design, design, construction, acceptance, and post-acceptance. The selection process is based on a points-based evaluation of demonstrated competence and qualifications, with the highest weight placed on performance on past representative projects. The County will select the most highly qualified provider and subsequently negotiate a fair and reasonable price in accordance with Texas Local Government Code 2254.004. Proponents must hold commissioning certification from the AABC Commissioning Group (ACG) and submit a Statement of Qualifications not exceeding 25 pages. The resulting professional services agreement requires monthly invoicing with supporting documentation and compliance with the Texas Government Code regarding payments. All work must adhere to the highest engineering standards and comply with federal, state, and local laws, including the Americans with Disabilities Act.
