1 construction resource allocation
1.1 construction team arrangement
1, the whole plant road, site and process installation works by the general contractor to organize their own construction.
2, four 3000m3 steel manufactured water tanks within the group company to seek internal construction unit subcontracting construction.
3, civil engineering, piling works and high and low voltage distribution instrumentation and self-control for professional subcontracting.
(1) Selection of subcontracting construction units by invitation to tender.
The civil construction of the whole plant is divided into two sections: pretreatment area, super-consideration and reverse osmosis workshop, office building, enclosure and biochemical treatment area and intermediate tanks, etc. Under the guidance of the competent authorities of the Group Company, the subcontracting construction unit will be selected by inviting tenders from the construction teams that have been licensed to enter Hong Kong for construction and have a similar track record of the technical difficulties of this project in the oilfields, which will be determined by the approval of the Project Construction Management Department.
(2) The civil construction subcontract is in the form of package contract. Among them, the construction of temporary construction by the general contractor unified construction of all concrete by the general contractor to build a mixing station unified production. Cement, steel and other major materials by the general contractor in accordance with the provisions of the Group designated material supply and marketing company supply. Bidding price is prepared in the form of package contract for commercial concrete and steel, cement and other main materials uniformly specified price of large-scale temporary requirements listed in the breakdown of separate offers. Signing the subcontract at the same time to the winning bid price minus the large temporary facilities provided by the general contractor for the cost of commercial concrete and steel, cement and other raw materials direct costs (according to uniform pricing) as the contract price.
1.2 construction equipment configuration plan
1, road, site, process installation construction equipment by the general contractor according to the need to configure the configuration plan in the preparation of the construction organization design according to the progress of the plan requirements.
2, civil engineering piling project construction equipment, machinery and tools by the subcontractor according to the need to configure the configuration plan in the preparation of the construction organization design according to the progress of the plan to determine the requirements and in the subcontracting bidding documents to put forward clear requirements.
3, lifting, transportation, earth moving construction with large equipment in principle, who construction who equipped (self-provided or rental can be). If the subcontracting unit has difficulties, the general contractor has the ability or can be rented within the oilfield to solve the problem, the general contractor will provide or help to contact within the oilfield to rent.
4, construction equipment configuration plan see annex 2: "deep sewage treatment plant construction equipment configuration plan list".
