The terminal comprises of two large storage buildings which were built in the 1970s, one is 80m x 100m and the other 100m x 180m, both are multi-span propped portals. The buildings were cladded in asbestos cement, with an asbestos fire wall on a boundary with an adjacent site, had roller shutter and personnel doors and generally were in a poor state of repair.
Encon’s scope of work was to remove all asbestos material, renew roof purlins and side rails and to re-clad both buildings with a single skin box profile sheet. All existing timber personnel doors were replaced with steel doors with vision panels and roller shutter doors replaced with a combination of fast acting and roller shutters. A new mechanical and electrical installation was provided in both buildings with aspirating fire detection due to the dusty nature of the Client’s operation. A new concrete floor slab was installed in one half of the larger building with 620 3m high pre cast concrete walls to form material bins for bulk storage. The internal columns in the bulk storage area were found to be severely corroded and the bottom 2m of all 28 required replacing, this proved to be a challenging engineering process as the building required propping in order to carry the renewal.
Externally, new surfacing was laid and services and concrete slabs provided for pre-fabricated offices and welfare units. The refurbishment of the buildings was executed consecutively and daily liaison was essential as the Client operation could not be stopped completely.
