Project Management and Site Organization
Project Management and Site Organization tests planning, scheduling, site layout, safety coordination and quality control from award to reception.
Planning tools
Gantt charts show sequence and duration; CPM identifies the critical path, the longest path through the network, with zero total float. Site layout must provide access, storage, crane coverage, welfare facilities and separation of pedestrian and vehicle routes. RD 1627/1997 requires a seguridad y salud plan, a coordinador and a libro de incidencias.
Control
Quality control includes recepción of materials, test plans and the final acta de recepción. Delay analysis compares planned and actual progress, not just the final date.
Worked example
Activities: A (3 days) and B (4 days) start at day 0; C (2 days) follows A; D (5 days) follows B and C. Early dates: A 0–3, B 0–4, C 3–5, D 5–10. The critical path is A–C–D, duration 10 days. B has 1 day of total float.
Traps
- Calling the shortest path critical.
- Confusing total float with free float.
- Planning without checking safety access routes.
- Certifying work that is installed but not tested.
