The initiative provides an assessment of underground reticulated services from a capacity, condition and compliance perspective. The extent of services includes communications/data, high voltage and low voltage reticulation, water and fire services, sewerage, stormwater, gas and fuel.
The scope of the assessment included the following services:
- Voice and ICT services
- Electrical services
- Water supply, including firefighting and irrigation systems
- Sewerage systems, including Defence-run treatment plants
- Storm water networks
- Fuel and gas networks
- Miscellaneous networks e.g. compressed air.
The project is delivered in accordance with the Defence Estate Quality Management System (DEQMS) suite of support services. The methodology includes detailed guidance and templates for both the project deliverables and the project lifecycle management. The BEAP methodology is based on three broad phases of work:
Phase 1 - Investigation and analysis.
Phase 1 involves a preliminary assessment and gap analysis of existing data, supported by stakeholder meetings and brief non-intrusive site investigations. The Phase 1 report is an ‘Interim’ report based on the final report deliverables and highlights the data and assessment gap. The report complements the detailed proposal for undertaking Phase 2 investigations.
Phase 2 - Physical Investigations.
Phase 2 involves detailed physical site investigations required to complete the services, where the capacity, condition of compliance of services cannot be substantiated at Phase 1 of the process. This phase also includes services modelling (supported by hydraulic analysis, flow monitoring, etc.) and any condition and compliance assessments (such as risk-based extrapolation derived from evidence-based investigations), required to complete individual service assessment.
Phase 3 - Final Reporting.
This phase provides the consolidated assessment of the findings of Phases 1 and 2 in a complete report accompanied with service assessment plans, electronic data files and the BEAP Data Management Tool (Issues Register).
