The project on a page
Kettlewick College is a Grade II* listed, operationally live Royal Navy training establishment. The Malthouse Block boiler house serves the principal accommodation via a primary heating circuit and hot-water secondary. The existing plant is end-of-life and is replaced in full, with continuity held throughout by the Principal Contractor's temporary boiler.

Objectives and performance measures
The plan targets a safe, continuity-preserving delivery to the fixed sum and the agreed completion date, on a heritage-sensitive live site. Progress is measured weekly against the baseline below, each with a defined source of evidence.
| Measure | Target | Evidence |
|---|---|---|
| Health and safety | Zero RIDDOR; PPE compliance 95% or above | Weekly supervisor log |
| Programme | Within 5% of the weekly baseline | Weekly Gantt update |
| Quality | 95% of hold-points cleared first time | ITP register |
| Commercial | Final Account within sum plus agreed variations | Monthly valuation |
| Heat continuity | Zero unscheduled heating or DHW outage | Estate incident log |
| Commissioning | All 54 BMS points and OEM sign-offs before PC | Commissioning records |
| Snagging | 12 or fewer items at handover | Joint snagging list |
Organisation and CDM duties
BuiltAI fields a defined delivery team, all operating under the Principal Contractor's construction phase plan. The company acts as designer for the Contractor's Design Portion only. The BMS specialist is appointed separately under the Prime Cost Sum at the Principal Contractor's instruction.
| Role | Responsibility | CDM duty |
|---|---|---|
| Director | Project sponsor, accountability, variation sign-off | Designer, CDP |
| Project Manager | Delivery, PC interface, programme, plan custodian | Site management |
| Commercial Manager | Valuations, variations, PS and PC Sum, Final Account | nil |
| Technical Lead | CDP design, RFIs, ITPs, designer interface | Designer assist |
| Site Supervisor | Full-time supervision, daily H&S | Operative supervision |
| QA/QC and Commissioning | ITPs, hold-points, BSRIA commissioning management | Quality records |
| H&S Adviser | RAMS, COSHH, RIDDOR liaison | H&S co-ordination |
Interface with Grimshaw & Bolt runs through their PM, site manager, commercial manager, H&S manager and the asbestos coordinator who issues the Certificate of Reoccupation.
Phased method and risk
The works run in ten phases within the on-site window. Heavy plant lifts in through the skylight in a single concentrated operation in Phase 4. Risk is held in a register of 18 items on a five-by-five likelihood and impact matrix; the leading five are shown.
| Phase | Focus | Window |
|---|---|---|
| P0 to P1 | Pre-construction, mobilisation, Stage 4a surveys | Jun to 10 Jul |
| P2 to P3 | Strip-out and builders' work | 20 Jul to 14 Aug |
| P4 | Heavy-plant lift-in through the skylight | 17 to 21 Aug |
| P5 to P6 | Mechanical, public health and electrical | 17 Aug to 18 Sep |
| P7 to P8 | BMS install and testing and commissioning | 14 Sep to 6 Oct |
| P9 to P10 | Changeover, handover, then 12-month DLP | from 5 Oct |
Certificate of Reoccupation slipping past 17 July; OEM price validity on the long-lead order; the weather window for the single-day heavy lift; the BMS specialist appointment timing under the PC Sum; and gas-supply verification, now closed by the metered pressure check. Each carries a named mitigation in the register.
