Claims Mitigation/Change Management M “Experience in planning and management using advanced system approach is key to keep a program organized, moving forward efficiently and on target to achieve cost, schedule, and quality goals.” anthos Engineering personnel have decades of experience in dealing with Claims Mitigation and Change Management. Mr. Manthos was responsible for the final two years of H-3 construction, which included the closing of outstanding Construction Contracts, many of which had over 100 Change Orders and claims totaling in the millions of dollars. He was directly responsible for negotiating all of the larger outstanding claims and reach resolution through negotiation, mediation and dispute resolution. Mr. Manthos was commended for resolving many outstanding claims without resorting to legal actions. He has also represented the State of Hawaii as the Highways Administrator in numerous court cases on other issues and is well versed in giving expert testimony.
Mr. Shiralian, as support to Manthos Engineering is uniquely qualified by being both a Lawyer and a Civil Engineer, specializing in claims management. His experience in Scheduling and his decade long relationship with Mr. Manthos began with the DOT Master schedule and has resulted in a unique support partnership for very complex claims that could have entered the legal arena if not properly handled. He has been involved with Kalaheo Sewer Project for over 5 years and was instrumental in the programming of the reconstruction of the Primavera CPM Schedule which was used in the claims negotiation for the first contractor who was unable to complete the work and was subsequently terminated.
Mr. Argov and Mr. Firby are actively involved in the current Kalaheo Sewer Reconstruction Project and have worked on numerous claims and change orders involving the previous contract just completed, which included Primavera CPM scheduling and satisfactory resolution of delay and impact claims through mediation. Through negotiations, the project was completed at substantial savings to the City, despite numerous differing site conditions claims
Mr. Lei served two opposite parties in two large City and County of Honolulu construction projects where contract disputes arose but were eventually resolved. In the first case Mr. Lei was an engineer working for a contractor who filed claim against the City while building a 60-inch diameter reinforced concrete pipe employing a drill and blast method. He collected and prepared engineering data in support of the contractor’s claims as well as presenting direct and indirectly costs associated with the claims, concentrating his efforts to maximize profits the contractor should justifiably received. In the second case Mr. Lei worked for a firm representing the City in a 48-dia. fiberglass reinforced pipe construction, where Mr. Lei aimed at minimized cost damages to the City. The highlight of his contribution was the research of project documents and the reconstruction of a Primavera CPM schedule, which provided the defense basis and enabled Mr. Lei’s team and the City to successfully dispute the contractor’s challenges.
The ability to review, (or create/reconstruct) complex CPM schedules is essential to meet critical timelines and to mitigate time claims for project management. Manthos Engineering is experienced in reconstructing Primavera CPM schedules based on daily reports and other information in order to settle outstanding claims and disputes, both for ongoing projects and ones where termination by the owner is necessitated. Primavera, both full form P3 and SureTrak software as well as Microsoft scheduling software dependent on project needs and requirements is available. All Change Orders are typically analyzed against field reports and construction schedules with requests for time extensions reviewed, based on impacts to the critical path
A detailed CPM schedule review is an essential component of our project management program. CPM schedules should be resource loaded to be considered accurate and effective in dealing with the Contractor’s Claims as well as in the initial approval and review for the project in order to define the production rates so to accurately predict the effect of delay on resource efficiencies and other indirect costs.
If a good CPM schedule is not available, we have the ability to reconstruct a detailed resource loaded CPM schedule, accurate enough to effectively reflect past construction activities using daily construction records.
Mr. Manthos was responsible for adjusting and approving all CPM Schedules for WMATA (Washington Metropolitan Transit Authority), and the Los Angeles Red Line Transit Project. He managed various Transit Construction Projects including Electric Power, SCADA (Supervisory Control and Data Acquisition), Elevators/Escalators and other building systems. These schedule submissions were rolled into a master schedule for the $1 Billion dollar project in Primavera Format and were utilized in various claim mitigation and resequencing operations.
Mr. Manthos as State Highways Administrator, instituted a central Primavera program (developed by Mr. Shiralian) to track all CIP and Maintenance funded Construction on an individual project milestone basis, thus enabling a complex schedule that resulted in compressing 10 years of H-1 rehabilitation into a two year period, reducing long term public disruption and maximizing state resources to increase production efficiency.
