Analysis of labor intensity losses upon amendments to operational documentation for a construction project

BACKGROUND: Active development of the Russian Arctic and the Northern Sea Route requires increased security. Now, there are seven icebreakers operating on the Northern Sea Route, but there are no patrol ships in the Arctic Region. To ensure national security in the Arctic, it is required to build ships as soon as possible. In prime contracts, designs and solutions often change, which shall be considered in construction and document finalization schedules. The authors examine the pipeline rerouting in a system of a construction project after amendments have been made to the prime contract operational documentation and, accordingly, to the working construction documentation. AIM: To find out how the pipeline rerouting process affects the construction process. METHODS: The article analyses the literature related to improvement of shipbuilding products and provides an overview of an industrial experiment with further comparative analysis. RESULTS: When the discrepancies are eliminated, the construction schedule of the project changes. CONCLUSIONS: Failure to timely amend the design documentation affects the construction schedule. The industrial experiment allowed us to conclude on the importance of inspecting the problematic area by all departments and the relevance of using automated systems.
