Temporary Works Education

Temporary works are structures put up to assist in the construction of major projects such as, tunnels, bridges, or buildings. This is done through provision of support, access & shield for the project under construction, simultaneously, ensuring the wellbeing of the public & workers. The purpose of the temporary structures is for maintenance, repair or inspection. On completion of the construction, the temporary structures are removed or integrated in to the refined work. Temporary structures take hold of the key to a winning building project (McGraw-hill, 2005).

Structural engineering is a specialty field within civil engineering that deals with the analysis & design of structures that support or/and resist heavy lots. The field seeks to advance quality both in performance & safety in the work of the design of permanent buildings & other non-building structures e.g. machinery, heavy industrial plants & medical equipments. In the work of the design of these permanent structures, temporary structures are often used to provide support to tunnels, bridges or buildings.

The relevant issues of safety necessary in the work of design & construction need to be keenly observed; the occupants & users of the structure under design need a safe & comfortable surroundings in which to live, work & play. For a firm structure that would withstand all expected pressures, a safety factor of is usually selected for building for every structural member..5 is the mostly used safety factor with.25 for the main landing gear &.0 for pressurized fuselages. This is because plenty of structures are disused with low value of building. Safety factor of is used for automobiles while yielding, metallic equipment makes use of the lower value like.4 &.0 for aircraft & spacecrafts respectively.

Temporary structures are useful in ensuring the stability of structures under design. The planning authority requires qualified structural engineers to ascertain the structural suitability & make positive that the project won't endanger lives after completion. The American Institute of Steel Construction (AISC) provides a code of standard practice that ought to be observed in the work of the construction using steel buildings & bridges in order to provide stability that can resist wind, seismic & other erection operations. Through the use of proper temporary structures, one-of-a-kind & long lasting structures are generated. For temporary structures to be used for a maximum of years period, the sub-contractor in charge of the project is responsible for construction of a quality product & provision of a safe working surroundings, all through the effective use of methods, techniques, tooling, & equipment. AWS structural welding code & AASHTO standard specifications for highway bridges & building code provided by OSHA ought to even be observed for safety purposes.
