AACEi :
Independent activities that may be, or are performed at the same time (fully or partially).

AACEi :
(1) Two or more delays that take place or overlap during the same period, either of which occurring alone would have affected the ultimate completion date. In practice, it can be difficult to apportion damages when the concurrent delays are due to the owner and contractor respectively.
(2) Concurrent delays occur when there are two or more independent causes of delay during the same time period. The “same” time period from which concurrency is measured, however, is not always literally within the exact period of time. For delays to be considered concurrent, most courts do not require that the period of concurrent delay precisely match. The period of “concurrency” of the delays can be related by circumstances, even though the circumstances may not have occurred during exactly the same time of period. [10]
(3) True concurrent delay is the occurrence of two or more delay events at the same time, one an employer risk event, the other a contractor risk event and the effects of which are felt at the same time. The term ‘concurrent delay’ is often used to describe the situation where two or more delay events arise at different times, but the effects of them are felt (in whole or in part) at the same time. To avoid confusion, this is more correctly termed the ‘concurrent effect’ of sequential delay events. [12]
(4) Concurrent delay occurs when both the owner and contractor delay the project or when either party delays the project during an excusable but non-compensable delay (e.g., abnormal weather). The delays need not occur simultaneously but can be on two parallel critical path chains.
(5) The condition where another delay-activity independent of the subject delay is affecting the ultimate completion of the chain of activities.

AACEi : 
Syn.: Cost Eatimate Category; Cost Estimate Classification System; Cost Estimate Type.

AACEi : 
There are numerous characteristics that can be used to categorize project cost estimate types. Some of these characteristics are: level of project definition, end usage of the estimate, estimating methodology, and the effort and time needed to prepare the estimate. AACE recommends that the primary characteristic used to define the classification category is the level of project. The other characteristics are considered secondary.
The level of project definition defines maturity, or the extent and types of input information available to the estimating process. Such inputs include project scope definition, requirements documents, specifications, project plans, drawings, calculations, lessons learned from past projects, reconnaissance data, and other deliverables and information that must be developed to define the project. Each industry will have a typical set of defining deliverables that are used to support the type of estimates used in that industry. The set of deliverables becomes more definitive and complete as the level of project definition (e.g., project engineering) progresses.
For projects, the estimate class designations that follow below are labeled Class 1, 2, 3, 4, and 5. A Class 5 estimate is based upon the lowest level of project definition, and a Class 1 estimate is closest to full project definition and maturity. This “countdown” approach considers that estimating is a process whereby successive estimates are prepared until a final estimate closes the process.

AACEi :
(Typical level of project definition required: 65% to 100% of full project definition.)Class 1 estimates are generally prepared for discrete parts or sections of the total project rather than for the entire project. The parts of the project estimated at this level of detail will typically be used by subcontractors for bids, or by owners for check estimates. The updated estimate is often referred to as the current control estimate and becomes the new baseline for cost/schedule control of the project. Class 1 estimates may be prepared for parts of the project to comprise a fair price estimate or bid check estimate to compare against a contractor’s or vendor’s bid estimate, or to evaluate/dispute claims or change orders.

AACEi : 
(Typical level of project definition required: 30% to 75% of full project definition.)Class 2 estimates are generally prepared to form a detailed control baseline against which all project work is monitored in terms of cost and progress control. For contractors, this class of estimate is often used as the “bid” estimate to establish contract value.

AACEi : 
(Typical level of project definition required: 10% to 40% of full project definition.)Class 3 estimates are generally prepared to form the basis for budget authorization, appropriation, and/or funding. Class 3 estimates are typically prepared to support full project funding requests, and become the first of the project phase “control estimate” against which all actual costs and resources will be monitored for variations to the budget. They are used as the project budget until replaced by more detailed estimates. In many owner organizations, a Class 3 estimate may be the last estimate required and could well form the only basis for cost/schedule control.

AACEi :
(Typical level of project definition required: 1% to 15% of full project definition.)Class 4 estimates are generally prepared based on limited information and subsequently have fairly wide accuracy ranges. They are typically used for project screening, determination of feasibility, concept evaluation, and preliminary (but generally not final) budget approval. Class 4 estimates are prepared for a number of purposes, such as but not limited to, detailed strategic planning, business development, project screening at more developed stages, alternative scheme analysis, confirmation of economic and/or technical feasibility, and preliminary budget approval or approval to proceed to next stage.

AACEi :
(Typical level of project definition required: >0% to 2% of full project definition.)Class 5 estimates are generally prepared based on very limited information, and subsequently have wide accuracy ranges. As such, some companies and organizations have elected to determine that due to the inherent inaccuracies, such estimates cannot be classified in a conventional and systemic manner. Class 5 estimates, due to the requirements of end use, may be prepared within a very limited amount of time and with little effort expended. Class 5 estimates are prepared for any number of strategic business planning purposes, such as but not limited to market studies, assessment of initial viability, evaluation of alternate schemes, project screening, project location studies, evaluation of resource needs and budgeting, long-range capital planning, etc.

AACEi : 
Syn.: Cost Estimate Category; Cost Estimate Class; Cost Estimate Classification System.

AACEi :
Cost estimating is the predictive process used to quantify, cost, and price the resources required by the scope of an investment option, activity, or project. Cost estimating is a process used to predict uncertain future costs. In that regard, a goal of cost estimating is to minimize the uncertainty of the estimate given the level and quality of scope definition. The outcome of cost estimating ideally includes both an expected cost and a probabilistic cost distribution. As a predictive process, historical reference cost data (where applicable) improve the reliability of cost estimating. Cost estimating, by providing the basis for budgets, also shares a goal with cost control of maximizing the probability of the actual cost outcome being the same as predicted.

PCI :
The process of predicting the costs of a project.

AACEi : 
In estimating, an algorithm or formula that is used to perform the costing operation. CERs show some resource (e.g., cost, quantity, or time) as a function of one or more parameters that quantify scope, execution strategies, or other defining elements. A CER may be formulated in a manner that, in addition to providing the most likely resource value, also provides a probability distribution for the resource value.

AACEi :
Project cost estimators predict the cost of a project for a defined scope, to be completed at a defined location and point of time in the future. Cost estimators assist in the economic evaluation of potential projects by supporting the development of project budgets, project resource requirements, and value engineering. They also support project control by providing input to the cost control baseline. Estimators collect and analyze data on all of the factors that can affect project costs such as: materials, equipment, labor, location, duration of the project, and other project requirements.

AACEi :
Differentiated from the critical path method, this project planning and management technique considers resources that constrain the work, not only the precedence of activities. The method determines the longest-duration sequence of resource-constrained activities through a project network—thus, the shortest-possible project duration—the critical chain. Algorithms for application of the method are both deterministic and stochastic.

CPM scheduling is the method of choice for managing projects of long duration, complex technical integration, or the need to coordinate fast or early completion of the work. Syn.: CPM.

PMI :
A method used to estimate the minimum project duration and determine the amount of scheduling flexibility on the logical network paths within the schedule model.

PCI :
The Critical Path Method (Calculate Schedule) is a modeling process that defines all the project's critical activities which must be completed on time. The Calc tool bar button on the Gantt and PERT (found in most GUI-based PM software) windows calculates the start and finish dates of activities in the project in two passes. The first pass calculates early start and finish dates from the earliest start date forward. The second pass calculates the late start and finish activities from the latest finish date backwards. The difference between the pairs of start and finish dates for each task is the float or slack time for the task (see FLOAT). Slack is the amount of time a task can be delayed without delaying the project completion date. A great advantage of this method is the fine-tuning that can be done to accelerate the project. Shorten various critical path activities, then check the schedule to see how it is affected by the changes. By experimenting in this manner, the optimal project schedule can be determined.

(1) Delays that are caused by the owner's actions or inactions. Contractor is entitled to a time extension and damage compensation for extra costs associated with the delay.
(2) If the delay is deemed compensable the party will be entitled to additional compensation for the costs of delay, as well as additional time for contract performance. However, it is possible for a delay to be compensable without extending the contract performance time. Generally speaking, a delay that could have been avoided by due care of one party is compensable to the innocent party suffering injury or damage as a result of the delay’s impact. [10]
