Mr. Sowinski has over 32 years of experience in heavy/highway, industrial, institutional, and commercial construction.  He has 20 years of on-site experience working as a project controls manager, scheduling engineer and project engineer on the construction of several major civil / highway and bridge projects, site developments, power plant facilities and commercial renovations.   

Mr. Sowinski has extensive experience in the area of CPM scheduling, planning and analysis, and has provided CPM schedule training to various DOT personnel in both classroom setting and one-on-one instruction.  In addition, Mark has significant experience analyzing contractor delay claims and preparing technical reports containing the results of the analyses.   He also has significant project management experience including contract administration, cost estimating/negotiating, and subcontractor coordination.  
Mark was the project controls manager responsible for the master schedule on the I-95 Express Toll Lanes (ETL) program from April, 2006 to July, 2011.    His involvement began during the design development stage and continued through pre-construction planning and construction.  He reported directly to the GEC Construction Manager and interacted daily with the MOT Manager, Contracts Manager and Lab Manager.  Mark managed a team of consultants responsible for the review, analysis, and reporting of CPM schedule and claim submissions on projects ranging in value from $2M to over $200M.

Mr. Sowinski has worked as lead consultant and team member on the review, analysis and reporting of several significant construction contract claims involving delay, disruption, lost productivity, and contractual entitlement issues.  Some notable examples are:

  • Shark River Bridge / NJ 35 (AMEC / Civil)
  • 14th Street Bridge (District of Columbia DOT)
  • Wharf Unit 2 – Port of Wilmington (DSPC)
  • East Gude Drive Bridge (Montgomery County DOT)
  • I-695 / North Approach to Key Bridge (MDTA / OAG)
  • Energy Systems Group (SHA-OOC / OAG)
  • I-95 / Contee Road Interchange (SHA-OOC)

More specifically, he evaluated claims involving multiple delay issues to determine causation, responsibility, concurrency, and ultimately time impact and related costs.  Mark performed issues analyses and delay analyses on claims ranging from $250K to over $50M. He also prepared as-built databases utilized in preparation of monthly CPM updates to support delay analyses.

Mr. Sowinski also reviews, monitors, and makes recommendations regarding acceptance or rejection of contemporaneous CPM Schedule submissions for several active DOT projects.  He prepares written reports describing project status, critical path evaluation, resource issues, earned value, delays and provides applicable schedule reports and charts.  Mark also evaluates time extension requests for merit and implements claims avoidance strategies.
