Spire provided construction scheduling services for the Amtrak Security Improvements Project located in the areas of Baltimore, Maryland and Washington, DC. Spire’s consultants were responsible for creating a master critical path method (CPM) schedule using Primavera P6; coordinating with the project team, subcontractors, and vendors; conducting site visits; setting up a work breakdown coding structure; building a work calendar; importing activities, and constructing logic sequencing. Once the preliminary schedule was approved, Spire’s consultants imported the appropriate cost and resource data into the CPM schedule to create the program integrated master baseline schedule. Spire continued to provide monthly schedule updates based on the actual project progress. These updates included bimonthly updates, bimonthly status and schedule reporting, monthly resource and cost histograms, and monthly S-curves based on the Level 4 schedule framework. Spire also provided as-needed schedule impact analysis. Spire was notified by its client that, in addition to its monthly schedule updates and reports, a time impact analysis (TIA) was required before our client submitting its payment documentation. Spire immediately and effectively brought the necessary stakeholders together with online meeting software to determine the best approach for assembling the required data, and identified the most appropriate analysis method.
