What is a Builders Work in Connection (BWIC)?

Builders Works in Connection (BWIC) refers to the supporting building works required to enable specialist services, such as mechanical, electrical, fire, hydraulic, or lift systems, to be properly installed. It includes tasks like creating penetrations, providing structural supports, forming plinths, installing access panels, and making good after services are fitted. BWIC ensures the building fabric is prepared for and coordinated with service installations, reducing clashes, delays, and rework during construction.
