Qatar’s Ras Laffan Company has invited companies to submit bids for two contracts to build waste management facilities and associated infrastructure.

Contractors have until 27 October to submit bids for the contract. The waste management centre will consist of two parts, part A and part B. Part A will involve the construction of one waste transfer station and two administrative buildings. Part B involves the provision of a new weighbridge, modification of the existing control room and road improvement works.

This is the latest of a number of waste management contracts that have been tendered in Qatar in 2013 as the government seeks to upgrade its utilities infrastructure.

In August, Ashghal invited companies to bid for the contract to build a domestic waste transfer station in the Al-Khor area of Doha.The work will involve building and providing all of the equipment and machinery for the waste management facility. In addition to the waste transfer station, the facilities will include a loading centre, administration building, staff accommodation building, storage building and an internal roads network. The contract will also involve building car parking and carrying out soft and hard landscaping.

In May, Ashghal received prequalification entries for the five main packages on the estimated QR10bn ($2.7bn) Inner Doha Resewerage Implementation Strategy (Idris).

The Idris project involves building a series of deep tunnels that will serve the Doha South catchment area over the next 50 years. The scheme will eliminate the need for pumping stations in the Doha South area.

The project also involves 76 kilometres of lateral interceptor sewers, 33km of trunk sewer, a terminal pump station, a New Doha South sewage treatment plant, 92km of treated sewage effluent return facilities and the decommissioning of 37 existing pump stations.

Ashghal appointed the US’ CH2M Hill in late 2011 to manage the scheme. The firm has worked on the concept design and preliminary design, and will also manage the design and construction consultants.
