1. INTRODUCTION
Time is money especially on engineering and construction projects. Because delays in the
completion of the project usually result in increased owner, engineer, and contractor costs, the
overall time of performance is vital to the financial success of the project. The importance of
time is evidenced by the significant role played by CPM schedules, completion dates, and
milestones in the bidding and awarding of engineering and construction contracts. The desire to
minimize costs and the time of performance often causes the occurrence of acceleration.
This article discusses the following topics:1
- Types of Acceleration;
- Key Elements of Acceleration Required by the Courts;
- Acceleration Claims Outside of the United States;
- Notice Requirements;
- The Relevance of the Date When the Time Extension Is Given;
- Contract Provisions Associated with Acceleration;
- The Effect of a "No Damage For Delay" Clause on Acceleration;
- Identifying Acceleration Using the Project Schedules;
- Documenting Acceleration Evidence; and
- Acceleration Damages.
2. TYPES OF ACCELERATION
There are three types of acceleration: directed acceleration, constructive acceleration, and voluntary acceleration.
Directed acceleration occurs when the owner or construction manager issues a specific order to
its construction contractor under the contract provisions to 1) complete the project earlier than
the originally scheduled completion date, 2) re-sequence the work and/or utilize overtime,
additional shifts, and/or extra engineering or construction labor, supervision, or equipment to
complete the base contract work plus additional or changed work within the original contract
time,2 or 3) re-sequence the work and/or utilize overtime, additional shifts, and/or extra
engineering or construction labor, supervision, or equipment to make-up for contractor-caused
delays that threaten the on-time completion of the project. These measures can result in costs
being incurred that would not otherwise have been required.
