The Project
The Challenge
Graham Ellis Associates (GEA) were commissioned by St Georges School to prepare a CIF application to the EFSA, to secure grant funding for an urgent re-roofing project at the school.
An intrusive survey was carried out, to identify those roofs which needed urgent repair. The existing roofs in some areas no longer watertight.
The Application for Grant Funding via the CIF Bid process required the format of the Bid to focus on the following criteria:
- Project Need
- Project Planning
- Value for Money
Project Need – required GEA to provide information on the urgency of the need, strength of evidence of the need and the nature and extent of the impact the refurbishment works would have on the school.
Project Planning – needed to address the appropriateness of the solution put forward by GEA, the time scales and a delivery plan.
Value for Money – GEA competitively tendered the project prior to submission of the Application to give ‘cost certainty’ before works started on site.
The preferred Contractor, after comparison and analysis of the tenders received was Q and A Roofing Ltd.
The accepted tender was within Budget.
The CIF Bid proved to be successful, and the school was notified.
The Remedy
GEA were tasked with providing the most cost-effective solution to deal with the problems encountered by the leaking and thermally inefficient roofs at the School.
A detailed Options Appraisal was undertaken to establish the most cost-effective solution,
An overlay roofing system was adopted, to lay on the existing deck to cause minimal disruption to the normal teaching and learning curriculum during the construction phase on site.
The new roofing system carries a 30-year guarantee.
The works comprised the following:
- Preparing the existing roof surface to accept new waterproofing – Roofs 1, 1a, 1b, 2, 3 and 4.
- Stripping existing roof- Roofs 3.
- Insulating roof areas to current building regulation standards.
- Re-Routing cables.
- Raising soil and vent pipes.
- Raising window thresholds.
- Temporary removal of cladding.
- Temporary removal of AC units and subsequent relocation.
- Improving drainage/falls (where required).
- Installing new edge details (where required).
- Removal of ACM’s (Asbestos Containing Materials) if necessary.
- Removal and capping of rooflights (where required).
- Replacement rooflights (where required).
- Providing rainwater outlets (where indicated).
- Installing all necessary flashings etc.
- Overlay existing roofs with new waterproofing system – Roofs 1, 1a, 1b, 2 and 4.
- Sundry minor repair and alterations

Before Commencement on Site
GEA chair a pre commencement meeting on site, with all the parties present, to establish and agree the following:
- The Contractors Programme
- To sign the Contract Document
- To discuss obligations imposed by the Employer working at the school.
- To discuss the site access route and position of compound
- To agree Health and Safety rules, CDM Compliance
- To agree a start date on site after mobilization of the Contractor
During the Project:
Weekly site visits were made by GEA to monitor progress on site.
A photographic record was maintained throughout the contract period on site.
Monthly site meetings were chaired and minuted by GEA and distributed to the school and the project team.
Monthly Financial Reports were provided to the Client to ‘firm up’ costs of any provisional sums or variations and to forecast the anticipated Final Account figure.
The End Result
The project achieved Practical Completion on time and to an excellent standard of workmanship.
The project was completed within the specified contract sum, with the School being kept fully informed with monthly Financial Reports during the construction phase, as to the anticipated final cost.
The before, during and after photographs show a vast aesthetic improvement to the refurbished blocks, with the additional benefit of insulation to improve thermal efficiency.
