Why use Modular construction ? Modular construction has been in the UK since the late 1970s The optimum size and span of the Modular units is dictated by but its rapid increase in recent years has occurred due to client transportation limits. Generally, buildings of up to 5 storeys demands in various well-defined sectors. There are five major can be designed without being over-engineered ( the same manufacturers of Modular units in the UK.)

2 A strong infra- Modular unit is used at all levels without need for structure of design, manufacture and supply exists, which has strengthening). For taller buildings, additional strengthening expanded to meet the increasing demand of the late 1990s. elements can be introduced. The motivation for using Modular construction generally arises Recent examples of the sectors that have used Modular because of over-riding client requirements for speed of construction are presented in this study. A number of case construction , improved quality, and for early return of examples of recent projects are presented in Case Studies on investment.

3 Furthermore, there is a noticeable trend to use Modular Steel Framing (P271). Modular construction in social housing, where speed of construction is allied to economy of production scale, and to reduced disruption in congested inner city sites.

This publication provides information and data on the Value assessment and financial Benefits of Modular construction using light steel framing. It is based on a background study in which a direct comparison was made between the Benefits of buildings using Modular construction and those built with traditional construction .

10 One part of the study involved case studies of seven projects using Modular construction as the chosen structural option. From these case studies, the following key advantages may be attributed to Modular construction using light steel framing: KEY ADVANTAGES OF Modular construction . Short build times Safer construction Typically 50-60% less than traditional on-site Modular construction sites have proved to be construction , leading to an earlier return on significantly safer than traditional on-site investment and saving in preliminaries. building.
