Construction joints must allow horizontal displacement right-angled to the joint surface that is normally caused by thermal and shrinkage movement. At the same time they must not allow vertical or rotational displacements.

Expansion Joint in building

Joints (1)Expansion=Isolation: horiz seperate sections/forms of slabs or walls; avoid thermal effects. (2)Contraction=Control:intentional cracks in slabs to prevent uncontrolled cracking;placed 4 to 5 feet apart, and should extend down to at least one quarter of the slab’s thickness(3)Construction joints provide internal framing for a concrete slab at the edges between different forms or between two pieces set on consecutive days.

Control=Contraction Joint:isolates 1major building component with another(example - new building abutting an existing building).Control joints are typically used in concrete to reduce the occurrence of shrinkage cracking.A control joint is a continuous vertical joint filled with mortar, but with a bond breaker If control joints are not provided, a concrete masonry wall may crack as it shrinks over time.http://www.masonryconstruction.com/brick/difference-between-control-and-expansion-joints.aspx

Expansion=Isolation Joint - Used within straight lengths of the same wall. Expansion joints, on the other hand, are typically used to accommodate thermal and moisture expansion in clay brick masonry. An expansion joint is a continuous vertical or horizontal joint, left completely free of mortar and filled with elastomeric sealant to keep it watertight.

Value Engineering (VE) is not a design/peer review or a cost-cutting exercise. VE is a creative, organized effort, which analyzes the requirements of a project for the purpose of achieving the essential functions at the lowest total costs (capital, staffing, energy, maintenance) over the life of the project.
