Forming part of a significant programme of investment being planned by the Council as part of their £149 million 21st Century Schools Capital Programme, the Pembroke Learning Campus comprises of a 1,463 place 11-18 secondary school, a vocational college, playing fields, car parking and external facilities.
Located on the site of the existing Pembrokeshire Comprehensive School, this new development provides an integrated facility comprising a 1,463 place 11-18 secondary school, a vocational college, playing fields, car parking and external facilities. The campus serves as a “learning hub” for the whole of the south of the country and includes a replacement SEN/autism centre as well as facilities for community engagement and multi- agency working.
The scheme is part of the Council’s £149m 21st Century Schools Capital Programme – a collaboration between the Welsh Government and Local Authorities.
As part of the tender submission Jubb redesigned the building foundations to speed up the construction programme and reduce the capital cost of the ground works. Ground improvement techniques were adopted to eliminate the need for deep foundations. Once the site was improved shallow pad foundation and a ground bearing floor slab were adopted. This saving played an important role in successfully winning the project. A 4 m high reinforced concrete retaining wall was utilised to meet the challenges of the steeply sloping site. The internal retaining wall was constructed using waterproof concrete to eliminate the need for complicated external waterproofing.
Balancing the cut and fill and keeping site won material on site was key to this successful project. Material was reused below sports pitches and incorporated into the landscaping. Jubb worked through the site levels carefully to ensure that the minimum amount of retaining structure was required to ensure best value to the scheme. The superstructure of the school was formed with hot rolled steelwork with a light gauge steelwork inner skin. Jubb reviewed the secondary steelwork requirements at an early stage to ensure all elements of the steelwork package were captured.
Jubb provided a foundation and frame solution to offer the minimum build cost available to suit the challenging project budget.
As part of the RIBA stage 1 and 2 design Jubb undertook a detailed review of the engineering elements to ensure a cost-effective approach was adopted. Working closely with the main contractor’s commercial team we took a step by step approach to appreciate the quality of the building while giving value for money. Our in-house geotechnical team were invaluable in providing expert foundation advice at every stage of the project.
Jubb reviewed the superstructure options for the building and recommended a steel frame solution as it was relatively fast and simple to erect and would ensure the building was watertight as early as possible in the programme. The value engineered foundation solution ensure the project was completed on time and within budget.
