CAPES case studies
CAPES · Put your knowledge to work in context.
CAPES - the Certified Associate in Project and Engineering Scheduling - is a multiple-choice credential aimed at schedulers, planning engineers, project controls analysts, and project managers who build and maintain project schedules in engineering and construction environments. It is an associate-level exam: it assumes you understand how a schedule is constructed and read, not that you have run a program controls office for a decade. The ten domains move from fundamentals and terminology, through WBS development, logic and duration estimating, and critical path calculation, into resource loading and leveling, cost loading, schedule risk and contingency, progress and performance analysis, change control, and finally schedule quality and validation. The weighting leans toward CPM and schedule calculation, so be prepared to compute forward and backward passes, total and free float, and to reason about what a logic change does to the critical path. The CAPES case studies are 5 cases and about 3,280 words.
1Steel-Procurement Lag and a Constraint That Hides the Critical Path
A hospital expansion has a 60-week baseline containing 2,100 activities. The contractor is preparing a delay analysis after a 45-day steel-delivery slip.

At the end of month 8 on a 24-month rail-signaling project, the control account reports PV = 5.0M, EV = 4.1M, AC = 4.6M, and BAC = 12.0M. The contractor's monthly report shows SPI = 0.82 and CPI = 0.89, and forecasts EAC = BAC / CPI = $13.47M.

A 14-month wastewater treatment plant is 30% complete when the client adds a 400-ton rooftop chiller. The chiller requires a new structural platform, a 6-week fabrication lead time, and a 3-week crane pick.
