In work measurement, a standard data system (SDS) is a database of normal time values, usually organized by work elements that can be used to establish time standards for tasks composed of work elements similar to those in the database.
A work breakdown structure is a key project management element that organizes the team's work into manageable sections. The Project Management Body of Knowledge defines the work-breakdown structure as a "hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create ...
0 no activity 50 very slow 75 steady 100 brisk (standard rating) 125 very fast 150 exceptionally fast The basic time for a task, or element, is the time for carrying out an element of work or an operation at standard rating. Basic time = observed time x observed rating The result is expressed in basic minutes – BMs.
In industrial engineering, the standard time is the time required by an average skilled operator, working at a normal pace, to perform a specified task using a prescribed method. [1] It includes appropriate allowances to allow the person to recover from fatigue and, where necessary, an additional allowance to cover contingent elements which may ...
A specific material may be covered in several locations, depending on the work result: stainless steel (for example) can be covered as a sheet material used in flashing and sheet Metal in division 07; it can be part of a finished product, such as a handrail, covered in division 05; or it can be a component of building hardware, covered in ...
A basic motion element is one of a set of fundamental motions used by a worker to perform a manual operation or task. The set consists of 18 elements, each describing one activity. Transport empty [unloaded] (TE): receiving an object with an empty hand. (Now called "Reach".) Grasp (G): grasping an object with the active hand.
Effort – The will to work; Conditions – The general work surroundings; Consistency – of performance; Each factor is assigned an alpha rating, e.g. “B-“, “C+”, “A”, etc. which has a numeric value which is applied later. This reduces the possibility of “clock rating” and ensures that all factors are considered in the ...
The Concrete Reinforcing Steel Institute (CRSI) has developed standard symbols, graphics, and formats for shop drawings and cut sheets that generally are used by reinforcing steel fabricators. [5] Each fabricator, has particular style for shop drawings and cut sheets, depending on the drafts people and Computer-aided design systems.
