Efficient construction claim management is necessary for all parties in a construction project. Claim
pricing is one of the most important sub-processes of claim management, which gives substantive description
and details of extra costs incurred or to be incurred due to change. This paper aims at 1) finding suitable pricing
method for each claim component of both contractors and employers, and 2) surveying claim pricing process of
existing employers’ claim management system. The research was done by reviewing literatures, analyzing
FIDIC’s “Conditions of Contract for Construction (First Edition)”, and performing interview of 29 key staff from
both public and private organizations. It was found that there are 23 contractor’s claim cost components and 22
employer’s claim cost components. From the survey results, Thai construction industry has much simpler claim
pricing methods than those theoretically described in international practices in several aspects, i.e. the number
of claim components and the indemnity method. This factor should be recognized in the development of the
industry dealing with the high international competitive atmosphere in the future.
