Dimensional control in the construction industry is an absolute necessity in terms of ensuring that the dimensional quality of the building is well defined. Its main purpose constitutes minimising the negative effects of cost and labour changes to the overall functionality of the space. In order to achieve precise and efficient dimensional control, a dimensional control plan must be designed before the building is constructed. The plan includes certain components such as tolerance plan, assembling plan, setting out plan and dimension-monitoring plan. Indicated below is the impact of dimensional control in small space construction.

Dimensional Control Basics

The purpose of dimensional control is to meet the predefined dimensional quality. The requirements that are put on the dimensional quality of a building can be technical quality, aesthetical quality and the combination of these two. Dimensional control is concerned with the whole activities including predicting, realizing and monitoring the dimensional quality. The objective of making a dimensional control plan is to meet the prescribed accuracy standards as accurately as necessary, and as inaccurately as possible, in view of accuracy-cost relation, to minimise the cost and to be acceptable in labour circumstance.

The dimensional control plan is designed on the basis of building drawings and specifications delivered by architects. First, a conceptual plan can be designed. The conceptual plan must fit within the whole conceptual construction plan. When making an assembling plan, one needs to plan how the building components are positioned and fastened, and predict corresponding deviations. In other words, the positioning points of an object, equipment used, and procedures followed must be identified.

Dimensional Control Monitoring

Dimension monitoring is another process in the dimensional control process. The execution of monitoring measures can happen from various viewpoints, but the ultimate purpose of it is to ensure or improve the dimensional quality. This can be done internally by the contractors or externally by the inspector or independent institute depending on the purpose of the dimension monitoring. To execute the task of dimension monitoring, a plan of dimension monitoring should be designed. This plan is closely related with the tolerance plan, setting out plan and positioning plan.

Dimensional Control Assesses Necessary Points in Small Space Construction

The essence of designing a dimensional control plan is to make an assessment of all the points needed and their related information, and decide which points should be chosen, for different purposes, such as setting out, assembling building components and temporary works like formworks, and monitoring the dimensional accuracy. The points and related information can then be transferred into a Total Station.

Dimensional Control is Important in the Engineering Process

Designing the dimensional control plan is a complex task. The designers must interpret the drawings, make an inventory of points needed, select appropriate points for different purposes and often add them to the drawings. When designing the plan, a lot of factors, such as prescribed accuracy and construction methods etc., should be considered. The designing process is in fact a decision-making and knowledge engineering process.
