During the project mobilisation phase, the contractor may be required to acquire surety bonds as a means of assuring the owner that the contractor will perform the work and pay its obligations. We shall define and describe these bonds in Chapter 5, but here we simply indicate that the forms to be used are often included in the package of contract documents, for the contractors use if and when the contract is awarded. Likewise, the general conditions are likely to require the contractor to carry certain types of insurance and those forms may be included in the project manual as well.
