5.2 Installations, Upgrades, and Repairs

This page is the closed-out works register for Lake Bennett Estate common property: installations, upgrades, and repairs that have been finished and documented. It is the counterpart to 5.1 Planned Upgrades and Outages (needed / proposed / scheduled work).

As-built detail for plant that still exists belongs on the relevant page in sections 3 or 4. This register records what changed, when, who did it, and where the manual was updated — so history is not only in people’s heads or contractor email.

Living Register

When a job on 5.1 is marked Complete, add a row (and a short detail section if useful) here, then update the asset page. Do not leave finished work only on the planned register.

How to Record a Closed-Out Job

1. Confirm the work is finished and services are restored
2. Add a row to the Works Log below (newest first)
3. Add a short detail section when contractors, isolations, or as-built changes matter later
4. Update the asset page in section 3 or 4 (photos, specs, map placemark, Show on Map link)
5. On 5.1, set status to Complete or remove the scheduled-outage row

What to Capture

Field	Record
Date	Practical completion (or date range if multi-day)
Type	Installation / Upgrade / Repair
System	Water, wastewater, power, roads, lighting, other
Asset	Named plant or location (match the manual / map where possible)
Summary	One or two sentences — what was done
Contractor	Company and contact if known
