Devaux's Index of Project Performance (usually known as the DIPP) is a project management performance metric [1] formulated by Stephen Devaux as part of the total project control (TPC) approach to project and program value analysis. It is an index that integrates the three variables of a project (scope, time and cost) into a single value-based ...
[1] Geometric dimensioning and tolerancing has provided geometrically defined, quantitative ways of defining flatness operationally. Flatness deviation may be defined in terms of least squares fit to a plane ("statistical flatness") or worst-case (the distance between the two closest parallel planes within). It can be specified for a given area ...
As cost estimating programs became more and more popular over the years, more advanced features, such as saving data for reuse, mass project-wide changes, and trade-specific calculations, have become available. [6] For example, programs that are designed for building construction, include libraries and program features for traditional builders.
Equipment - (1) a category of cost for organizing and summarizing costs, (2) construction equipment used to execute the project work, (3) engineered equipment such as pumps or tanks. Escalation is defined as changes in the cost or price of specific goods or services in a given economy over a period. In estimates, escalation is an allowance to ...
The 16 Divisions of construction, as defined by the Construction Specifications Institute (CSI)'s MasterFormat, is the most widely used standard for organizing specifications and other written information for commercial and institutional building projects in the U.S. and Canada. In 2004, MasterFormat was updated and expanded to 50 Divisions. [1]
Lean construction supplements traditional construction management approaches with (Abdelhamid 2007): (1) two critical and necessary dimensions for successful capital project delivery by requiring the deliberate consideration of material and information flow and value generation in a production system; and (2) different project and production ...
Lapping machine. Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.
For example, in designing a staircase, a dead load factor may be 1.2 times the weight of the structure, and a live load factor may be 1.6 times the maximum expected live load. These two "factored loads" are combined (added) to determine the "required strength" of the staircase.
