Civil Engineering - BEM PCE Civil & Structural
Civil Engineering is one of the two domains tested in the BEM Professional Competency Examination (PCE) for Civil & Structural candidates. It assesses your ability to apply Malaysian practice to infrastructure works: site investigation and earthworks, stormwater drainage, road geometry and traffic, water supply, and environmental controls. Answers are marked on code-correct method, units, and buildability, not on lengthy description.
Core rules and concepts
- Design stormwater using MSMA (Manual Saliran Mesra Alam): the rational method Q = C i A / 360 applies to small catchments, with i in mm/h and A in hectares; check time of concentration and the design ARI.
- Provide minor and major drainage systems; maintain freeboard, outlet control, and silt traps; obtain discharge permission before connecting to a public drain.
- Earthworks: balance cut and fill, specify compaction (commonly 95% MDD for embankments), and verify bearing capacity through site investigation.
- Road design follows JKR geometric standards: horizontal and vertical curves, sight distance, superelevation, and pavement thickness based on traffic loading.
- Environmental controls include an erosion and sediment control plan (ESCP), silt fences, and detention/OSD where required by the local authority.
Worked example
A 12 ha catchment has C = 0.55 and 10-year intensity i = 180 mm/h. Q = 0.55 × 180 × 12 / 360 = 3.3 m³/s. If the proposed drain capacity is 3.0 m³/s, it fails; increase the section, reduce C through attenuation, or provide OSD. State the equation, units, and the decision.
Traps that cost marks
- Using i in mm/h with A in m²; the 360 constant only works with hectares.
- Ignoring time of concentration and applying peak intensity to the whole catchment.
- Designing only the minor system and omitting the major overland flow path.
- Quoting a compaction figure without linking it to the specification and testing frequency.
