Replacing approximately <br />3 months of summer working conditions with 3 months of winter working conditions resulted in a <br />net duration increase for numerous construction activities, which ultimately extends the overall <br />construction schedule. This is not something that could have been calculated accurately or <br />completely previously. <br />o For example, a major portion of the concrete work, which this project has an abundance of, was <br />required to be completed during the winter months. Placing concrete in the winter is undeniably <br />met with lower worker productivity but also an increase in workload/tasks, such as temporary <br />heating and cover, for which each concrete pour had to be covered for approximately five days: <br />essentially leading to a loss of one week between pours. <br />o The availability and delivery of process piping has changed dramatically since the inception of <br />this project. Previously, the spool pieces that are field measured and custom ordered took <br />approximately two weeks to arrive onsite, currently these orders are averaging around six and <br />half weeks. This change is most likely attributed to market instability, including tariffs and raw <br />material availability. <br />o This is a complex project with complex challenges. As we all strive to get this project right, to <br />date there have been over 60 RFI's and 40 construction modification proposals. All of these <br />changes/modifications take time, not only from a construction perspective, to actually complete <br />the work, but also from a design standpoint, to review, research and recommend the best solution. <br />Most clarifications or modifications result in some form of schedule impact which can either be <br />measured individually for daily or weekly impacts, or in this case, holistically, by only adding <br />what is truly required. <br />Magney Construction, Inc. is an Equal Opportunity Employer <br />
