#8 Cost Estimate and Bid Documents

Read Chapter 7 Bidding and Procurement in Construction Project Management by Gould and Joyce
Factors of Bid Process

If a project has the ingredients necessary to return a good profit, the motivation to bid is high.

The factors that make one company succeed over another include:
- Relationships with key subcontractors
- Knowledge of and experience with the specific type of project
- Ability to buy out the job
- Estimating capability
- Project team setup
- Safety records
- How efficiently they conduct their business
- Overhead costs

Direct costs + Indirect Costs = Cost of the work
Cost of the work + % of Overhead and Profit = Total Cost to the Owner

Insurance

Workers’ compensation: State law that compensates employees who are injured on the job. (covers disability and medical treatments)

Comprehensive liability: Protects the contractor against third-party claims.

Builder’s risk: Property insurance for the building, while it is under control of the contractor. Protects against property damage during construction. (covers losses resulting from fire, smoke, water, explosions, vandalism, and theft)

Bonds

Bid Bond: If the contractor withdraws, he or she agrees to pay a percentage of the bid cost as stipulated in the bid documents—usually 5 to 10 percent of the bid itself.

Performance Bond: If the contractor goes bankrupt or otherwise cannot complete the work, the bonding company becomes liable for it.

Payment Bond: Also called labor and material bonds. This assures that the contractor will pay all the bills, thus leaving the owner unharmed by claims and liens.
