Therefore, a departure from the recommended protocols should not be automatically treated as an error or a deficiency as long as such a departure is based on a conscious and sound application of schedule analysis principles.” “ This Recommended Practice is not intended to establish a standard of practice, nor is it intended to be a prescriptive document applied without exception. However, as stated in the introduction section within AACEI 29R-03, it is not prescriptive and must be considered in conjunction with the provisions of the contract: The purpose of any time extension claim is to relieve the contractor from paying liquidated damages for critical delays that have occurred, for which it is excused responsibility under the contract.ĪACE International Recommended Practice ‘29R-03’ provides useful guidance on delay analysis. It is believed that the TSA has an advantage over other retrospective methods of delay analysis, such as, as-planned vs as-built in windows, as it provides a contemporaneous view more accurately modeling the impact of an event. Using the two methods together allows the analyst to model the likely impact of any event within a chosen period or window and thereafter, measure the actual impact based on the progress recorded during that period or window. The TSA takes advantage of both, combining a forward-looking approach (prospective) and backward-looking approach (retrospective).
The TSA combines two separate method implementation protocols (‘MIP’) that are described in AACE 29R-03 in a single delay analysis.ĭelay analysis methods are generally classified into two types: prospective or retrospective. This article explores a hybrid form of delay analysis, namely the time slice window analysis (‘TSA’), to arrive at an assessment of excusable delay (‘ED’) and excusable compensable delay (‘ECD’). - Regulatory Investigations & White-Collar Crime.- Forensic Accounting & Corporate Fraud.Forensic Engineering, Architectural & Technical.Dispute Forum and International Arbitration.
