# Construction Project Management Construction project management is the discipline of planning, coordinating, and controlling the delivery of a building project from inception to completion — on time, within budget, to the required quality, and safely. For the practicing architect, understanding project management principles is essential: the architect is frequently the lead consultant during design stages, may administer the construction contract, and must coordinate their own work within the broader project framework. The distinction between designing a building and delivering a building is the domain of project management. --- ## Table of Contents - [Project Lifecycle](#project-lifecycle) - [Roles and Responsibilities](#roles-and-responsibilities) - [Programme and Scheduling](#programme-and-scheduling) - [Cost Management](#cost-management) - [Risk Management](#risk-management) - [Quality Management](#quality-management) - [Communication and Reporting](#communication-and-reporting) - [Health and Safety Management](#health-and-safety-management) - [Post-Completion](#post-completion) - [See Also](#see-also) --- ## Project Lifecycle | Phase | Key Activities | Duration (typical) | |-------|---------------|-------------------| | **Inception** | Business case;

provides funding; makes key decisions; owns risk | | **Project manager** | Coordinates all parties; manages programme, cost, and quality; reports to client | | **Architect (lead consultant)** | Design leadership; coordination of design team; contract administration (if appointed) | | **Structural engineer** | Structural design; foundation design; structural inspections | | **M&E engineer** | Building services design; commissioning oversight | | **Quantity surveyor / cost consultant** | Cost planning; cost control; valuations; final account | | **Principal designer** (CDM) | Pre-construction health and safety; hazard elimination through design | | **Principal contractor** | On-site construction;

administers JCT/NEC contract | | **Employer's agent** | Design & Build — acts for client; equivalent to contract administrator | | **Contractor's design manager** | D&B — manages contractor's design team; coordinates novated consultants | | **Construction manager** | CM route — manages trade contractors directly on behalf of client | --- ## Programme and Scheduling ### Programme Types | Type | Description | Application | |------|------------|------------| | **Master programme** | High-level milestones; entire project lifecycle | Client reporting; feasibility | | **Design programme** | Detailed design stage activities; information release dates | Design team management | | **Construction programme** | Detailed construction activities;

preventing delays | ### Critical Path Method (CPM) The critical path is the longest sequence of dependent activities through the project — any delay on the critical path delays the project completion date. **Key scheduling concepts**: | Concept | Definition | |---------|-----------| | **Activity** | A discrete work task with duration, resources, and dependencies | | **Dependency** | Finish-to-start (FS), start-to-start (SS), finish-to-finish (FF) relationships | | **Float/slack** | Time an activity can be delayed without delaying the project | | **Critical path** | Activities with zero float — any delay extends the project | | **Milestone** | Zero-duration event marking a significant achievement | | **Baseline** | The approved original programme against which progress is measured | **Software**: Primavera P6 (industry standard for large projects); Microsoft Project; Asta Powerproject. ### Typical Construction Durations | Building Type | Duration (approximate) | |--------------|----------------------| | Residential (single house) | 6-12 months | | Residential (50-unit apartment block) | 14-24 months | | Office (5,000 m²) | 12-18 months | | Office (20,000 m²) | 18-30 months | | School (primary, 1FE) | 10-14 months | | Hospital (major) | 24-48 months | | High-rise (30+ storey) | 24-48 months | --- ## Cost Management ### Cost Plan Stages | Stage | Cost Document | Basis | Accuracy | |-------|-------------|-------|----------| | **Feasibility** | Order of cost estimate | £/m² benchmarks | ±25-30% | | **Stage 2** | Cost Plan 1 (elemental estimate) | Elemental rates; design areas | ±15-20% | | **Stage 3** | Cost Plan 2 (developed estimate) | Approximate quantities | ±10-15% | | **Stage 4** | Pre-tender estimate | Detailed measurement; specifications | ±5-10% | | **Tender** | Tender sum | Contractor's priced tender | Firm price | | **Construction** | Anticipated final account | Tender + variations + provisional sums | Ongoing | | **Completion** | Final account | Agreed final cost | Agreed | ### Construction Cost Benchmarks (UK, 2024) | Building Type | Construction Cost Range (£/m² GIA) | |--------------|-----------------------------------| | Social housing | £1,800-2,500 | | Private residential (apartments) | £2,500-4,000 | | Office (Grade A) | £2,800-4,500 | | Primary school | £2,200-3,000 | | Secondary school | £2,500-3,500 | | Hospital (acute) | £4,000-6,500 | | Hotel (3-4 star) | £2,500-4,000 | | Industrial / warehouse | £800-1,500 | | Retail (shell) | £1,200-2,000 | *These are order-of-magnitude benchmarks only;
