Transmission and Distribution Electrical Engineering, Third Edition

A project is the process of creating a specific result. Infrastructure transmission and distribution development projects all tend to follow the same general phases as shown in Fig. 22.6.
The concept and planning stages will require the type of financial and economic evaluation together with finance resourcing as detailed in Sections 22.2 and 22.3. In a fast track project, where the client requires very fast completion times, considerable overlapping of the different project phases occurs. This is not to be recommended unless the particular project work is well understood and has been completed before. Such fast track project work has a history of escalating prices and in some cases much longer construction periods than originally envisaged. The most important point is to ensure clear definition of the exact project requirements. Although the different project phases cannot usually be compartmentalized into clearly defined boxes with rigid start and end dates, rules should be set up such that sufficient definition is available before commencing each project phase. For example so many percent of steel work design complete before ordering, so many percent orders placed before delivery to site, so much paving and access road laid before commencement of steelwork erection (to avoid the site becoming a quagmire in Winter), etc. Only in this way will rework costs be kept under control in a fast track or indeed a more traditional project.
It is also important to understand the relative...
