Tender for the Construction of Eastside Sewage Transfer Scheme (South)

Description

HM Government of Gibraltar invites tenders for the construction of the Eastside Sewage Transfer Scheme. This Eastside Sewage Transfer Scheme, will install new, larger pumps at ESPS and a pair of rising mains (355mm and 450mm outside diameter) to facilitate transfer of sewage from ESPS to a location immediately upstream manhole 42 on the Trunk Sewer. This discharge point bypasses those parts of the sewage network which are already at or near capacity. Once operational, new and existing local pumping stations and gravity sewers will be diverted to ESPS. Flows to ESPS will increase as new pumping stations are constructed for new developments thus requiring different phases of operation of ESPS. The Eastside Pumping Station shall pump foul sewage from Eastside Pumping Station (ESPS) to a new manhole located on the trunk sewer just upstream of manhole 42 near the southern bus stop on South Pavilion Road. The rising main shall terminate at the junction of Transport Road and South Pavilion Road and from there flows will be conveyed by gravity to the new manhole. Eastside Pumping Station is located off Devil's Tower Road to the north of Beach View Terraces. The main is approximately 4.2km long with 0.9km being in the tunnel network within The Rock and the remainder shall be laid in road. The Eastside Sewage Transfer Scheme shall be divided into several works packages. This package relates to the South section of the Eastside Sewage Transfer Scheme as more particularly described within Appendix A of the Employer's Requirements. Interested parties will need to register their interest, complete and submit their responses via HM Government of Gibraltar's Supplier Network Portal https://hmgogsupplier.gibraltar.gov.gi User guides on how to register on this portal are available at http://www.procurement.gov.gi/index.php/guides/96-procurement-eservice-user-guides Additional information: Gibraltar does not participate in the Agreement on Government Procurement (GPA) under the World Trade Organization (WTO). HM Government of Gibraltar therefore reserves the right to consider only those bids from eligible tenderers in Gibraltar, the UK, or a country or territory covered by a trade agreement extending to Gibraltar that contains relevant procurement provisions.
