Contractor: Bovis Construction
Type of works: design, manufacture and installation of lead shielding to Brachytherapy rooms.
Envirotect was employed by Bovis Construction to install the lead shielding to the Brachytherapy Departments at the new oncology wing sited at St. James' Hospital in Leeds.
The contract was awarded for the design and installation of the structural rooms, as well as almost 200 tonnes of chevron lead blocks to shield the walls ranging in thickness from 15 to 50mm.
The most challenging task was to design and install six powered doorsets, each incorporating 15mm of lead.
The doors had to be hinged to match all the other doors within their location, which entailed fabricating special hinges and low-deflection frames to take the 450kg loads.
Envirotect also supplied around a thousand sheets of lead-lined plasterboard to the dry lining contractor for the general x-ray, CT rooms and operating theatres.
