Case Study - PPM's

Service: Building Surveying & Planned Preventative Maintenance (PPM)
Sector: Residential
Location: West London

We were instructed to undertake a comprehensive condition assessment of a residential block of flats and develop a long-term maintenance strategy to support effective asset management.

The client required:

• A clear understanding of the building’s current condition
• Identification of both internal and external repair requirements
• A structured Planned Preventative Maintenance (PPM) programme
• Budget forecasting over 5, 10, and 15-year periods
• Schedules of works suitable for contractor pricing

1. Drone & Physical Surveys
We carried out a detailed inspection of the building, combining:

• Drone survey technology to assess high-level and hard-to-access areas (roof coverings, elevations, rainwater goods)
• Internal and external walkover inspections to identify defects and maintenance requirements

This approach ensured a comprehensive and efficient assessment without the need for intrusive access equipment.

2. Condition Assessment & Reporting
We evaluated the condition of key building elements, including:

• Roofs and rainwater systems
• External façades and finishes
• Windows and doors
• Internal common parts

Defects were recorded, prioritised, and linked to recommended remedial actions.

3. Planned Preventative Maintenance (PPM)
Based on our findings, we developed a structured PPM programme, setting out:

• Short-, medium-, and long-term maintenance requirements
• Lifecycle considerations for key components
• Prioritisation of works based on condition and risk

4. Budget Forecasting
We prepared forward-looking budget cost plans covering:

• 5-year (short-term)
• 10-year (medium-term)
• 15-year (long-term)

This provided the client with a clear financial roadmap for maintaining the asset.

5. Schedules of Works
To support procurement, we produced detailed schedules of works, enabling:

• Issue to contractors for competitive pricing
• Consistency and clarity in tender returns
• Efficient progression into delivery phases

• Drone-assisted inspection for high-level access
• Full internal and external condition survey
• Structured PPM aligned with lifecycle planning
• Budget forecasting across 5, 10, and 15 years
• Tender-ready schedules of works

• ✔ Clear visibility of current building condition
• ✔ Prioritised and actionable maintenance strategy
• ✔ Robust long-term financial planning tool
• ✔ Improved ability to procure works efficiently
• ✔ Reduced risk of reactive and unplanned expenditure
