Public Authorities and Agencies
Stages of a construction project:
- Briefing Stage
- Designing Stage
- Tendering Stage
- Construction Stage
- Commissioning Stage
Enable the client to specify project functions and costs for the design team to interpret accurately and provide cost estimates.
Briefing Stage
- to complete the project brief, finalize the layout, determine the methods of construction, and estimate costs to secure necessary approvals from the client and
Designing Stage
- aims to appoint one or more contractors to perform the site works.
Tendering Stage
- Site organization involves setting a detailed plan for task schedules, arranging temporary facilities, and securing material storage. Planning for manpower ensures that the correct type and number of workers are available at each stage. A materials logistics plan guarantees timely delivery to avoid delays.
Construction Stage
- Systems are tested to verify that all mechanical, electrical, and plumbing installations function according to design. Inspections ensure compliance with regulations. Training sessions are conducted for facility managers, and all manuals, warranties, and as-built drawings are handed over.
Commissioning Stage
Types of Contracts:
- Competitive Bid Contracts
- Negotiated Contracts
types of competitive bid contracts
- Unit Price Contracts
- Lump Sum Contracts
Based on a per-unit price; flexible but the total cost remains unknown until the project is complete.
Unit Price Contracts
Bidding on the total amount required by the plans and specifications; straightforward but challenging if modifications are needed during construction.
Lump Sum Contracts
Types of Negotiated Contracts
- Cost+percentage of cost
- Cost+Fixed Fee
- Cost+Sliding Scales of Fees
- Cost+guarantee ceiling price
Offers the contractor profit as a percentage of project costs but creates an incentive to inflate costs.
Cost+Percentage of Cost
Removes the incentive to inflate costs but shifts financial risk to the owner.
Cost+Fixed Fee
Contractor fees vary based on cost performance.
Cost+Sliding Scales of Fees
The contractor guarantees that the project will not exceed a pre- determined maximum cost.
