Tenders are hereby invited for Drilling, Casing, Cementing, Developing and Testing of a New Sub-artesian Bore for the Morven Water Supply.
Works to be carried out under this Contract comprise the drilling, casing, cementing, developing and testing of one sub-artesian production bore using rotary drilling plant. The depth of the completed bore is expected to be 650 metres and it is expected to have a standing water level around 75 metres below ground surface.
From surface to 6 metres shall be cased with either PVC or steel tubing with an internal diameter no less than 250mm. This conductor pipe shall be cemented in place. From surface to 190 metres shall be cased with 219mm O.D. casing. From 180 metres to 480 metres shall be cased with 168mm O.D. casing. A final string of 127mm O.D. slotted casing shall extend from 470 metres to bottom. The 219mm and 168mm strings of casings shall be pressure cemented.
The contract excludes supply and installation of pumping equipment and associated works.
All work under the contract shall be carried out by a responsible and experienced driller with a current Class 3 Driller’s Licence issued by the Queensland Department of Natural Resources and endorsed for the construction method to be used. Drilling equipment shall meet any DNR inspection and certification requirements. Drillers should not contract for or attempt works which could be reasonably expected to exceed the depth, diameter or casing load rating of the drill plant to be used.
Tenders will be awarded based on an analysis of weighted selection criteria. Notwithstanding such analysis, Council reserves the right to select the submission that in view of all the circumstances appears to be the most advantageous.
It is expected the contract will be awarded early May. Contract period will be eight (8) weeks unless otherwise agreed at tender stage. Offers shall state proposed contract period if different to the above.
