Transmission Construction Department

Transmission Construction Department (TCD) under Transmission Services (TS) of BPC is responsible for construction of high voltage (66 kV and above) transmission lines, substations and associated O&M infrastructures of BPC. The construction works undertaken are mostly for network expansion through BPC’s investment plan or deposit work from hydroelectric projects (HEP). Network expansions are associated with grid extension work to provide reliable and adequate power and also for export of surplus power to India. TCD and the Project Offices is responsible for tendering and award of work, monitoring and supervision of the construction and quality control. The construction works are executed by engaging both local and international (mostly from India) contractors. The Engineering and Design is taken up by the Engineering, Design and Contracts Department. Technical assistance from firms like POWERGRID and WAPCOS / CEA are also sought in design, engineering and monitoring especially for construction of 400 kV transmission line and substation projects. Consultants are also mandated to help develop in-house expertise in design and monitoring through close interaction and training both at site and consultants home. TCD is headed by a General Manager. Project offices headed by Superintending Engineer (SE) or Senior Project Manager (SPM) are created on a project base for better co-ordination and management of site work progress and quality. Project Offices are established based on the requirement of taking up new projects. The transmission lines, substations and O&M infrastructures are handed over to Transmission Department (TD) after completion, commissioning and capitalization for O&M purpose.

The present Organogram of TCD is as show below:
