“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.”
Mr. Pericles Manthos established Manthos Engineering after serving
Hawaii as Highways Administrator and later heading large mainland
transportation initiatives for a multi-state private firm. He and his staff
bring a wide range of experience in dealing with Program and
Construction Management issues, from inception through completion.
Manthos Engineering provides services for all project phases. We
have taken projects from conceptual design, through environmental
documentation, design, cost analysis, scheduling, and construction
management. Our understanding of all project aspects is key to our
ability to meet client’s goals for deadlines, cost, and quality control.
Claims Mitigation/Change Management
Manthos 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 60inch 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 48dia. 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.
Scheduling
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.
