PAM 1998 AND 2006 CONTRACT FORM
PAM 1998 vs 2006 Contract Forms The risk allocation for time, money matters, quality issues and dispute resolution between the contractor, employer and consultant team has been shifted significantly in the PAM 2006. Comparatively (1998/2006) the risk for Contractors under 2006 has been shifted towards the Employer. This reallocation of risks proportionately increases the employer’s exposure and burden in terms of claims and payments while providing more possible grounds for disputes between the contractor and employer.
PAM 2006 Forms are also more procedural requiring the contractor, employer and consultants to strictly adhere to time provisions with the attendant loss of rights or incurring of liabilities. PAM 2006 imposes definite and at times, mandatory time periods on the Architect/consultant team to carry out certain duties, for example, certification and approvals within a specified time. The failure to do so may open the consultant team to professional negligence claims.
