Identifying, Quantifying, and Proving Loss of Productivity (71-21)


Prepared by the ASCE Standards Committee including Robert M. D’Onofrio (CPMI) and Todd Mayo (CPMI)

Identifying, Quantifying, and Proving Loss of Productivity, ANSI/ASCE/CI 71-21, describes key labor costs as typically the most variable, and a major component of, overall project cost.

November 2018

by Robert M. D’Onofrio (CPMI), Shona Frame and Laura McEwen

Schedule Delay Analysis (67-17)


Prepared by the ASCE Standards Committee including Robert M. D’Onofrio (CPMI)

Schedule Delay Analysis (67-17) presents guiding principles that can be used on construction projects to determine the impact of delays. Critical path method (CPM) schedules can be of evidential value to demonstrate causation and liability and to apportion delays when they occur on a project. CPM schedules will influence the quantification of delay and, ultimately, whether a party was damaged by a delay. This standard provides 35 guidelines that allow for segmentation of responsibility for delays to intermediary milestones and project completion dates. It is available electronically in ASCE’s library.

What Is a Schedule Good for? A Study of Issues Posed by Schedules on Complex Projects

Winter 2013

by Robert M. D’Onofrio (CPMI) and Anthony L. Meagher

Construction lawyers and scheduling consultants have long grappled with the various methods of analyzing schedule delays. Recently, efforts have been made to establish common nomenclature and consensus regarding preferred methods. This article, published by the American Bar Association, Construction Lawyer, explores those efforts, offers suggestions as to the application of preferred methods, and discusses related considerations in drafting contract schedule provisions.

Scheduling (Programme) Analysis: Hired Gun Advocacy or Effectively Meeting a Burden of Proof?

October 2012

by Donald G. Gavin and Robert M. D’Onofrio (CPMI)

There is an undeniable need for logical, factually supportable and credible evidence to assist in calculating delay, time extensions, concurrency, and compensability, as well as liquidated damages and actual damages. Yet the differing methods of scheduling (programme) analysis can lead to distrust and rejection of some or all resulting evidence. This feature article in Construction Law International suggests a series of best practices to improve the reliability of such evidence and to increase its acceptability.

Under Construction – Can There Be Float on the Critical Path?

August 2010

by Robert M. D’Onofrio (CPMI)

Historically, activities with zero float were defined as the critical path. This is not always the case, however. Critical path activities can have float; hence the critical path can have float. This article dispels a common misconception.

The ABCs of DRBs: What They Are and How Well They Work

Spring 2006

by the Team at CPMI

For a host of reasons, disputes have become increasingly prevalent in the construction industry. When they affect deadlines, productivity, and costs, they must be dealt with promptly to keep the project on schedule and the budget on target. One approach to resolution, which has been evolving since its inception almost 30 years ago, is the use of a Dispute Review Board (DRB).

Identifying Concurrent Delay

Winter 2004

by the Team at CPMI

Properly assessing concurrent delay can be one of the most difficult challenges encountered in resolving delay claims. First, of course, it’s essential to understand how concurrent delay is defined.

When the Best-Laid Plans Go Astray: A Primer on Labor Productivity

Fall 2002

by the Team at CPMI

It all begins with the bid.

When a contractor bids on a construction project, the bid usually is based on an estimate, which is factored from a similar project. The bid contains materials and labor as its two primary components.

Techniques and Methods for Assessing Delays

Spring 2002

by the Team at CPMI

Time is important to everyone, especially to those in the construction industry. Every construction contract stipulates either a time of performance or a specific project completion date. Yet, with so much attention to time, construction projects are frequently subject to delays. Sorting out the issues and determining which party is responsible often proves difficult and time-consuming. Though many techniques are available for determining schedule impacts, not all produce valid results.
