INTRODUCTION
Project management entails designing, ordering, expediting, inspection, transportation of materials and equipment in an orderly sequence and then erecting them in different geographical locations and commissioning them into viable operating plants A large project, in totality, may appear to he very gigantic and complicated. Management of projects by network analysis provides an integrated technique of planning and control by breaking the entire project into various packages (systems) which are further blown into various functional components like mechanical, piping, civil, structural, electrical, instrument, etc. Each of these functions is further divided into design and indenting, ordering and payment, expediting and inspection, transportation and storage, erection and commissioning.
IMPORTANCE OF PLANNING FOR MATERIALS AND EQUIPMENT:
Procurement of materials and equipment spans across 80-85 per cent of the overall project duration. If we carry out delay-analysis of projects in India, late delivery of materials and equipment would emerge as the most important factor contributing to delays in project implementation. If we skim, through the annual reports of corporations implementing major projects, unforeseen delays (?) by vendors come in as a convenient alibi for all acts of omission and commission by the project managers.
NETWORK-BASED MATERIAL MANAGEMENT
Project management encompasses designing and indenting of materials, ordering and expediting them and then transporting these materials to the construction site and erecting them in respective geographical locations. Management of projects through network analysis incorporates a systematic and comprehensive approach to materials management. Effective materials management ensures right materials, in the right quantity at the right time, at the right place and at the right price.
Network analysis of projects leads to prioritisation of all activities such that work on the longest delivery items-is started first, followed by not-so-long delivery items, followed by medium delivery items and ultimately followed by short delivery items and so on.
SUMMARY
Materials and equipment play important role in project management, because the procurement of these requires 80-85 per cent of the overall project duration. Management of projects through network analysis incorporates a systematic and compresive approach to materials management. Effective material management ensures right materials, in the right of quantity at the right time, at the right place and at the right price.
The overall project duration is dependent upon the congest delivery items of materials and equipments. Hence possible courses of actions are to be followed in beating the critical path. Construction schedules shall have to he worked out in greater details so as to optimize the engagement of expensive construction machines and materials.
