BP has invited contractors to provide basic prices for building and infrastructure work on its $15bn-20bn Khazzan tight gas project in Oman.

Contractors have sent the company indicative unit rates for basic construction work, such as concrete placement and steel work, together with hourly labour rates.

The prices will be used by the project’s front-end engineering and design (feed) contractor, Australia’s WorleyParsons, to develop a budget for the facilities supporting the scheme, as well as provide a list of potential contractors that could work on the project once construction starts.

The work involves the construction of a variety of buildings and infrastructure that will be used by people working on the scheme, which will be the largest project in the sultanate. The structures include:

• Gatehouse
• Mosque
• Substations
• Sports hall
• Warehouses
• Workshops
• Medical centres
• Administration and office buildings
• Fire and police stations

BP is also thought to have prequalified engineering, procurement and construction (EPC) contractors for several major packages on the project. Central to the scheme is a processing plant able to produce 1 billion cubic feet a day (cf/d) of sales gas.
