PWCS OB1 – Stream Repairs

This project involved many work locations of varying sizes. The work had been split up into conveyors and their relevant support trestles. The project started up on the three largest trestles which required extensive scaffolding to access the works, the largest of which was approximately 28m high. This access had to also involve hoarding around one conveyor that sat in the middle of the scaffolding. Successfully, this hoarding prevented any coal dust from entering the work area and any garnet and paint entering the conveyor system.

There were two work activities to be completed once on these scaffolds: remediation of the coatings and corrosion with steel works done on any areas that required strengthening; and replacement of bolts along all three of the major trestles involving careful planning and staging of all works in that area. All three trestles were completed within their programmed dates (with relevant EOT’s and delays taken into account), with a high standard of quality for the repairs and coatings.

The works which continued after these major trestles were similar in scope but on a smaller scale, with 8 medium sized trestles to be tackled (8-10m high) and over 40 smaller (2-4m high) trestles.
