Beware fast tracking complex high rise buildings
By Samer Skaik
In complex high rise projects, employers tend to fast track works where construction can begin while design is still incomplete following three main phases of procurement. Shoring system and piling are firstly procured and awarded to an enabling contractor. Upon completion of enabling works, main design and traditional tendering of the second phase can be concluded in order for main construction works to commence on site. While main work is progressing, design of specialist packages will be completed and nominated subcontractors are appointed in a timely manner shaping the third phase of procurement. Such common phased construction usually results in substantial time saving in project life cycle. However, many fast track projects suffer time and cost overruns due to inherent risks of fast tracking such as design deficiencies and ambiguities in risk allocation between involved parties. This paper aims to investigate pros and cons of fast track procurement approach for complex high rise projects and examine how relevant risks are allocated among enabling contractors, main contractors, nominated subcontractors and project consultants in theory and practice. …
