Overview

Green Construction Services, LLC provides independent building commissioning, retro-commissioning, and third-party QA/QC services for mechanical, electrical, plumbing, and control systems.

Services

New Commissioning

Verification of building system installation, testing, and operations to ensure compliance with contract documents, owners' project requirements, and industry commissioning standards. This construction-phase verification process supports predictable system startup and reduces operational risks across commercial, institutional, and mission-critical facilities.

Existing Building and Retro-Commissioning

Systematic evaluation and optimization of operational, occupied facilities to identify and correct performance deficiencies. This process helps resolve operational issues, accommodates changes in building use, and improves lifecycle efficiency.

Third-Party Commissioning Support and QA/QC

Independent technical oversight and quality verification during project design and construction phases. This verification provides owners, designers, and contractors with objective validation of installation quality, equipment readiness, and system performance.

Diagnostic and Technical Studies

Specialized engineering investigations and technical assessments designed to troubleshoot issues, support larger commissioning scopes, and inform owner decision-making.
