The Performance Work Statement (PWS) outlines requirements for mechanical building maintenance services at the McNamara Headquarters Complex (HQC). The contract encompasses a range of maintenance tasks including HVAC, plumbing, fire alarms, and general mechanical systems to ensure compliance with government safety standards and building codes over a five-year period, divided into one base year and four option years. A primary aim is to maintain the functionality and safety of facilities frequently visited by high-ranking officials. Key responsibilities include both routine and emergency maintenance, compliance with regulatory requirements, management of service orders, and documentation of work performed. The contractor must perform at least 95% of services directly and handle various tasks such as equipment operation, preventive maintenance, and necessary repairs. The structure allows for flexibility in service demands through an Indefinite Delivery/Indefinite Quantity (IDIQ) contract approach. The document stresses the importance of quality assurance and compliance with regulations including the Americans with Disabilities Act and other industry standards to mitigate risks associated with facility maintenance services. Overall, this PWS serves as a comprehensive guide for contractors while outlining expectations for service delivery to maintain operational standards within the HQC.
