BBV Sublot 4 - HSST1020 - Saltley Deep Drainage

Tender description

A Subcontractor is required to undertake deep drainage within the Saltley Section of Sublot 4. The drainage is approximately 400m in length at 900mm diameter and ranges from 2.5m deep to 7.2m deep, with ground water sitting at approximately 2.5-3.0m deep. The assumption is that some of this pipework would be undertaken using trenchless techniques whilst some of the drainage might be installed traditionally (excavation and ground support). It is also considered that some of the manholes may be sunk rather than excavated with ground support. The package will be to provide labour, plant and temporary works for the installation of the drainage assets (pipework and manholes) using the methodology determined by the Subcontractor. Permanent works materials will be provided by the Contractor with any temporary materials needed by the Subcontractor to facilitate their works provided by themselves, as well as any sundry items. It is suggested that a pre-tender meeting is undertaken with interested bidders to ensure that the design that is being developed is in line with their technical requirements for any trenchless operations. Additional information: Suppliers should be aware of the scale of this project and should assess their internal capabilities to be able to carry out the intended scope of work, prior to completing this expression of interest (EOI).
