About Clem Grehan

Lead Planner / Senior Planner on Major Infrastructure - experienced in constructing and planningClem Grehan has not just planned projects, he has also physically built them - roads, railway lines, ports, tunnels, mines, oils & gas facilities with their structural, mechanical, piping & electrical components.Clem’s preferred method of planning and monitoring projects is using “Linear Programming”, but he has used MS Project and Primavera P3 & P6 since 1995. Clem is considered an expert in Primavera & project planning.Clem critically assesses the design, thinks through the constructability and takes off his own quantities (to check the bill) as he plans and schedules the project. Here is an example where Clem has made millions of dollar$ difference:-"Singapore Metro contract had tunnels alignments clashing with bridge piers, requiring costly permanent works to create clear spans for the tunnels to pass under. Clem studied as-builts of bridge footings, executed new surveys, calculated pile locations and redesigned the complex spiral tunnel alignments to miss 3 sets of bridge footings. Singapore’s Land Transport Authority approved the revised alignments and Contractor NLBJV / Nishimatsu saved over $1 million in costs and months of work. Project Director Isomura, GM Kado or Engineer Paul Broome (now MacDow Perth) can confirm".So when you employ Clem Grehan to do your planning, you get a designer with an eye for constructability, a QS for checking quantities, an experienced supervisor for assessing the best method of employing men and machines, a controls manager sizing up cost vs time (earned value analysis) and your plan will be realistic and effective to use. Claims – good at getting to the real issues in these also.Specialties: Project Planning / Scheduling Project ManagementProject CoordinationContractor ManagementContractor SupervisionGovernment ContractingNegotiationPerformance ManagementProblem SolvingProgress Monitoring
