A simulation model can be built to describe the construction activities of a scope of work ranging from large, complex industrial projects to a simple room of a small building. Using simulation, engineers can test out different construction scenarios, estimate resource utilization and find bottlenecks, and forecast time and cost requirements without having to go to site. This paper describes the pipe spool fabrication model built at Consolidated Contractors Group (CCC) .  \nKeywords: pipe spool fabrication, discrete event simulation  \n1. INTRODUCTION  \nOn a large industrial project, pipe spool fabrication is a major component of the construction operation. It is also a relatively short term, complex construction process often riddled with uncertainty due to the intrinsic unique nature of its outputs and the numerous factors affecting its activities. As such, it is important for all stakeholders to have a good grasp of the performance of pipe fabrication shops and their ability to meet the site pipe installation schedules. The ability of computer based modeling and simulation to model resource and activity interactions, queuing, and uncertainties renders it a good fit for modeling the pipespool fabrication process.  \n2. PIPE SPOOL FABRICATION MODEL  \n2.1. Background  \nConstruction contractors on large industrial projects often build one or more project specific pipe fabrication shops to handle the pipe spool fabrication scope. These shops are built to handle a specific set of pipe fabrication activities including cut and bevel, fit-up, welding, QC inspection, post weld heat treatment, non-  \ndestructive testing, and painting. Each of these activities is repeatedly performed by a specific type of crew on pipe spools. Each time it is performed, a crew is utilized for a certain duration and the result is specific progress of a pipe spool along its path to completion. With the large number of spools and their diverse characteristics and resource requirements, forecasting pipe spool fabrication activity completion and optimizing resource allocation and utilization becomes a complex task well suited to computer modeling and simulation.  \n2.2. Simulator Design and Development  \nThe simulator was developed to aid stakeholders in arriving at answers to the issues stated above. The first step was the abstraction of the real world situation into a simulation model representing the operations of a pipespool fabrication shop, including detailing the product and process definitions for all the main activities. In order to understand the nature of how pipe spool fabrication activities were performed on construction sites, extended visits to multiple mega industrial projects were conducted to observe and document the above mentioned set of activities. Benchmarking for every activity was conducted via numerous observations of the activity being performed on different spools of varying characteristics. Both crew composition information and productivity figures were collected. In this","cbCailb90M6yH7HL","https://ap.wps.com/l/cbCailb90M6yH7HL","pdf",485848,"English","# Abstract\n# 1.
