Tender ID: 434662
Tender Details
Tender Description
A sinkhole has formed beneath the dilapidated sewer pump station concrete slab located on Mackenzie Street in Blackwater. The sinkhole is approximately 5-6 meters deep and has formed due to damage at the interface of the existing sewer pipe and the abandoned pump station.
Central Highlands Regional Council (CHRC) requires a suitable Contractor to realign sewer pipes and to demolish and backfill the existing dilapidated pump station. Approximately 82m of new SewerMAX pipes are to be installed at an approximate depth of 3 meters as well as three new manholes (one with a drop inlet to 5m deep to connect to the existing sewer). The Contractor will also be required to ensure the existing sewer system is operational at all times using a bypass system.
