Pre-CPM Claims of Delay

• Generally, if two parties claim concurrent delays, the court will not try to unravel the factors involved and will disallow the claims by both parties. In United States vs. Citizens and Southern National Bank, 367 F. 2d 473 (1966), a subcontractor was able to show delay damages caused by the general contractor. However, the general contractor, in turn, was able to demonstrate that portions of the damages were caused by factors for which he was not responsible. In the absence of clear evidence separating the two claims, the court rejected both claims, stating:

“As the evidence does not provide any reasonable basis for allocating the additional costs among those contributing factors, we conclude that the entire claim should have been rejected.” CPM in Construction Management, 6th Edition, page 547

Post-CPM Claims of Delay• The courts gave early recognition to the validity of CPM. In 1972 (Appeal of

Minmar Builders, Inc. GSBCANo. 3430, 72-2 BOA), the court rejected a claim based on bar graph schedules, stating:

“The schedules were not prepared by the Critical Path Method (CPM) and, hence, are not probative as to whether any particular activity or group of activities was on the critical path or constituted the pacing element for the project.”

• Also in 1972, a Missouri Court (Natkin & Co. v. Fuller. 347 F Supp 17) stated that bar charts did not “afford an overall coordinated schedule of the total work covered by the contract.”

• An Illinois court (Pathman Construction Co. v. Hi-Way Electric Co. 65 Ill. App. ad 480, 382 N.E. 2d 453,460) in 1978 noted that

“technological advances and the use of computers to devise work schedules and chart progress on a particular project have facilitated the court’s ability to allocate damages.”

Specific Flaws of this CPM

• Frye Credential Test• Daubert Theory Test• Testimony by Expert• Ultimate Conclusion

Analytical Gap Test

Specific Flaws of this CPM

• Is the As-Planned a CPM or only a bar-chart?• Logic network from one start end to one finish end – no other open ends!

• Every activity must have a physical methodology predecessor & successor

• Activities Placed by Logic Restraints – NOT Date Constraints

• Proper Logic May Be Restated in “ADM” Finish-to-Start-no-Lag Format

• Resource (preferential) Logic Not Probative for Delay Analyses• But how do we distinguish Physical from Resource Logic?

• How reliable is this CPM to establish a claim of delay or disruption?

Direct ExaminationTestimony for the Contractor

attacking the report

• set the predicate for a proper CPM• every activity (other than first) must have a predecessor• every activity (other than last) must have a successor• if these rules not followed the logic network will have open ends• what is wrong with open ends?• this required logic must be methodology (physical), not just resource • non-physical resource restraint example – crew from tower to tower• if non-physical resource restraints are removed – more open ends?

• does CPM used for this analysis meet these criteria?
