The steps taken during the construction process to reduce environmental impacts:
Innovative construction management techniques have been detailed within the Project Environmental Management Plan, the main aims and objectives are:

  • To eliminate pollutants
  • To minimise impact of any flora, fauna and local inhabitants
  • To reduce energy consumption
  • To maximise the re-use and recycling of materials
  • To include environmental considerations in the selection of materials and components
  • To promote environmental awareness amongst staff, sub-contractors and suppliers
  • To accommodate any comments made following the further environmental assessments, any commitments agreed through discussions with local residents and/ or organisations.

A list of any social or economically sustainable measures achieved/ piloted:
It was necessary to create a new building which demonstrates that Dyffryn Aman is a school for the 21st Century. The main problem with the existing buildings was a lack of coherence with tortuous, external circulation routes. It was necessary to add new buildings but these are a small proportion of the overall work as it is more expensive to demolish and rebuild than to adapt.

New buildings have been provided to develop key resources for Special Educational Needs (Block 17) and to develop the Sixth Form along with providing new reception / administration areas to welcome visitors to the school (Block1 18).

After redevelopment, the school will be able to provide adequately sized, sufficient teaching and social spaces which are a pleasant place to work and learn. The school will be adapted with added facilities to ensure it is fully inclusive and helps every child.

In addition to the above, the following have also been met:

  • The first credit of Man6: Consultation (under BREEAM Education 2008) has been achieved;
  • Building users have visited site during construction, including regular visits form school teachers and pupils.
  • Building users and key stakeholders have attended Design Team meetings.

Project Description:
The overall project is extending and adapting the existing school, Block 18 is being constructed to create a new sixth form centre with IT study rooms. The lower floor will be new management and administrative spaces.
