Professional Practice, Project Management and Communication
Professional Practice, Project Management and Communication tests the non-technical half of engineering: how work is scoped, procured, programmed, controlled and reported, and how a materials engineer behaves inside a project team under contract.
Delivery and control
Know the contract model before giving advice: lump sum, re-measurement, design-and-build, or an NEC4 ECC option. Progress is measured with earned value - PV, EV, AC; SV = EV - PV, CV = EV - AC, SPI = EV/PV, CPI = EV/AC, and forecast EAC = BAC/CPI. Earned value warns you; recovery needs a critical-path review, where float identifies which activity can slip without moving completion.
Quality and change
Every material-critical activity belongs in an Inspection and Test Plan with hold points (work cannot proceed without sign-off) and witness points (notice given, attendance optional). Non-conformance reports must be dispositioned as rework, repair by concession, or reject, and closed only after verification. Method statements, mock-ups and sample approvals front-load decisions. Changes go through a variation with cost and time assessed before instruction; RFIs are answered in writing and logged; verbal instructions are confirmed the same day.
Communication
Match the message to the audience: the client needs risk, cost and time; the fabricator needs dimensions, tolerances and standards; the site needs a sequence and hold points. Maintain a drawing register with revision control, minutes with actions and owners, and a single common data environment (ISO 19650) for BIM. Present uncertainty honestly - a range with its basis beats a false single number.
Worked example
At month 6 of a 12-month HK$12M package: PV = 6.0M, EV = 5.4M, AC = 6.3M. SPI = 0.90 and CPI = 0.857, so the job is late and over cost; EAC = 12/0.857 = 14.0M, a 2.0M forecast overrun. Report the variance with its cause - for example rework from a failed coating inspection - a recovery plan against the critical path, and the cost of that recovery, not just the indices.
Traps
Confusing earned value with money spent; forecasting with SPI when delay sits on a non-critical path; releasing a hold point without the required witness; closing an NCR without verification; instructing a variation before assessing cost and programme effect; relying on verbal agreement; presenting a single number without its basis or uncertainty.
