The Project

The Challenge

Graham Ellis Associates (GEA) were commissioned by Castledon School to prepare an application to the ESFA, to secure grant funding via the CIF for an urgent re-roofing and window project at the school.

A comprehensive survey was carried out, to identify those roofs and windows which were in need of urgent repair/replacement.

The CIF Bid 

The Application for Grant Funding 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.

GEA were successful in obtaining a total of £531,522.82 in funding via the ESFA for 2 projects. £200,783.73 was obtained for the window works and £330.739.09 for the roofing works.

Following analysis of the tenders received, the preferred Contractor was Acclaim Contracts.

The accepted tender was £46,000.00 within Budget.

The CIF Bid proved to be successful, and the school was notified.

The Remedy

An intrusive roof survey was carried out, taking core samples which indicated 1550m2 of the flat roofing area was designated Grade D (marked red on plan) which was in need of immediate replacement. An initial budget was set of £330,739.09 to include replacement flat roofs, roof lights and removal of asbestos.

Scope of Works

GEA were tasked with providing the most cost effective solution to deal with the defective roofs and the problems encountered by the leaking roofs at the Academy.

An overlay roofing system was adopted, which would cause minimal disruption to the teaching and learning curriculum and also carried a 25 year guarantee.

The works comprised the following:

  • Preparing the existing roof surface to accept new waterproofing;
  • Insulating the roof areas to current building regulation standards;
  • Re-routing cables;
  • Raising soil and vent pipes;
  • Raising window thresholds;
  • Improving drainage/falls to roofs;
  • Installing new edge details;
  • Removal of ACM’s (Asbestos Containing Materials);
  • Removal and capping of compliant roof lights (where required);
  • Providing rainwater outlets and down pipes where indicated;
  • Installing all necessary flashings;
  • Overlay existing roofs with new waterproofing system.

Consultancy Services – Pre and Post Contract

The services provided by GEA on this project were as follows: 

  • Budget Estimates, Feasibility Studies.
  • Surveying the existing roof structures and taking core samples.
  • Preparation of Specification, Description of Materials and Workmanship.
  • Agreeing re-roofing design/specification.
  • Advice on Procurement and Contract Selection.
  • Preparing Tender Documents.
  • Analysing Tenders returned, preparing a Tender Report with recommendations.
  • Producing Site Specific Scope of Works for the site and agreeing the Contract Sum with the Contractor.
  • Monitoring Contractor’s Progress on site.
  • Cost control – Interim Valuation payments and Financial Statements.
  • Monitoring Health & Safety on site.
  • Agreement of Contractors Final Account.
  • Sign off at Practical Completion (PC)

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 any obligations imposed by the Employer on the contractor working at the school
  • To discuss the site access route and position of the 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 Academy 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.
