Service life

Years in service. One stated life so far; the band will widen as sources are added.

One source. This value rests on a single document (Design standards: employer's requirements – Technical Manual (ER-DFE-XX-XX-T-X-0201, revision A-C01), p323). Treat it as that source's figure, not a settled life, until others confirm it.

Basis

• 15 years · Design standards: employer's requirements – Technical Manual (ER-DFE-XX-XX-T-X-0201, revision A-C01), p323 · 5.11.4 “Sensors and actuators: 15 years” — Department for Education (England) (design life)
  Printed page 323. BMS sensors and actuators, types not stated. Minimum life expectancy (design requirement) for DfE-funded school buildings. Minimum design requirements placed on contractors for school buildings, not observed replacement ages. Section 5.1.4 (sanitaryware) refers to CIBSE Guide M Appendix 12.A1 'in general'.
• 15 years · Design standards: employer's requirements – Technical Manual (ER-DFE-XX-XX-T-X-0201, revision A-C01), p365 · 6.4.4 “Environmental sensors: 15 years” — Department for Education (England) (design life)
  Printed page 365. Building technologies section; environmental sensors (room temperature, CO2, humidity). Minimum life expectancy (design requirement) for DfE-funded school buildings. Minimum design requirements placed on contractors for school buildings, not observed replacement ages. Section 5.1.4 (sanitaryware) refers to CIBSE Guide M Appendix 12.A1 'in general'.

How sources are chosen and recorded: sourcing policy.

Preventive maintenance

2 tasks in 2 work orders. Intervals that fall due together are one visit: the annual visit also covers the semi-annual tasks.

Months from the schedule start. Download the tasks as CSV for a CMMS, or ask the MCP tool get_pm_schedule for dated visits.

Frequencies are ISO 8601 durations in the data (P3M = every 3 months).

Open questions

• Every source here is a published planning, design or accounting life. None is observed replacement data.
