Issues in the design and management in the 2nd West-to-East Gas Pipeline Project

Problems in terms of design quality and progress, corresponding construction and change measures are very likely to occur when facing so many operation and information interfaces due to huge project of 2nd West-to-East Gas Pipeline, for instance, offtake quantity and changes of delivery points of downstream users, incomplete equipment information, proposals of revision to the design by operation units at construction phase, difficulties in route confirmation resulted by local planning, incapability of local coordination, shallow preliminary establishment and geological investigation and long period of special estimation and document submission and approval. In addition, missing items in construction drawings, unspecific geological investigation and design, inefficient communication and coordination among design partners, less efficient work of design units and frequent alternations on drawing designs will bring great impact on the construction progress and costs. This paper therefore puts forward feasible suggestions to the design improvement, based on summarizing and analyzing design and management issues found in project implementation.
