In the construction business it is a frame to support workers and any material they may need temporarily to complete a construction project. Scaffold workers can repair and build large buildings without being impaired by building height using a scaffold lift system.
Getting the best value engineering is not always about cost savings. Let’s look at the dictionary meaning of value;
“to consider with respect to worth, excellence, usefulness, or importance.” Source
In construction engineering there are two parts to value; function and costs. An engineer may suggest alternate methods to complete the task at hand that
A) Add more functionality at little to no extra cost. An example of this may apply to an owner of a building. Typically owners have to pay the cost of heating and power. An engineer can suggest ways to reduce the cost of both by using a more energy efficient design. This benefits the owner of the building and consumers (if owner rents or sells units)
B) Reduces the cost of a project without sacrificing any functions. An example of this is foundation thickness. If soil pressure testing checks out, concrete (foundation) thickness may be reduced. This can save money on the material purchased to pour the foundation.
It is a system of organized procedural decisions designed to deliver more value to the project. The beneficiaries of value engineering services are clients, contractors, owners or end consumers. It has been an accepted engineering review & analysis practice since the 1940′s. In the 40′s the original concept was developed by General Electric Company to cut back on costs in a time of war (World War 2). VE is the acronym for this procedure although VEA (value engineering analysis) is also a recognized term.
Tilt-up Concrete Construction, also known as tiltwall, is a method of constructing concrete buildings where the walls are poured on the slab then lifted into place. Once the slab has been poured and cured, workers create the forms for the walls directly on the slab. Door and window openings are built into the forms. Then workers tie the reinforcing steel grid inside the forms. Inserts and embeds are installed for lifting the panels and connecting them to the footing, roof and other components. Cement is poured into the form.
Once the concrete has cured the formwork is removed. Cables are connected to the inserts and the wall sections are lifted into place using a crane. Temporary braces connect the wall panel to the slab until all walls and the roof have been installed. The process is repeated until all of the wall panels have been installed. A finish is applied to the walls and the joints are caulked.
The Tilt-Up Construction and Engineering Manual – 6th Edition published by the Tilt-up Concrete Association is a great resource for more information.
