The Project

The Challenge

Graham Ellis Associates (GEA) were commissioned by Hamstel Infant School and Nursery to prepare an application to the ESFA, to secure grant funding via the CIF for an urgent Roofing Refurbishment project to replace failing an uninsulated flat roof area at the school.

A comprehensive and intrusive 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 the required funding to carry out the Urgent Roofing Refurbishment works as the school.

After analysis, the preferred Contractors tender was within budget.

The Remedy

An intrusive roof survey was carried out, taking core samples of the flat roofing area showed the areas designated Grade D (marked red on plan) which was in need of immediate replacement.

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 Uninsulated areas.

An overlay roofing system was adopted to Roofs 3, 4 and 6, which would cause minimal disruption to the schools normal teaching and learning curriculum during the construction phase and also carried a 30 year guarantee.

However, Roofs 1, 2 and 5 were required to be stripped back to deck and a completely new roofing system would be installed which also carried a 30 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 mains gas pipe.
  • Raising window thresholds.
  • Improving drainage to roof surface laid to falls.
  • Removal and capping of non-compliant roof lights (where required).
  • Providing rainwater outlets and down pipes where indicated.
  • Installing all necessary flashings;
  • Overlay existing roofs with new waterproofing system (Roofs 3, 4 and 6).
  • Strip Back to Deck and New Roofing System (Roofs 1, 2 and 5)
