Chelmsford High School for Girls

Summary = Enabling works to Chelmsford County High School for Girls ahead of the construction of a new Sports Hall and teaching block, which will include additional science facilities

Location = Chelmsford, Essex

Architect = PCH Associates

Challenge = Removal of an existing building in a live school

Solution = Enabling works to Chelmsford County High School for Girls which included the following:

  • Removal of the existing building called Bancroft and infilling the site
  • Division of existing services from Bancroft, in order to keep the swimming pool and all other blocks operational
  • Clearance and re-levelling of work site, including embankment adjacent to science block
  • Sawston Village College

    Summary = Roof works and internal decoration to two college buildings

    Location = Cambridgeshire

    Architect = PCH Associates

    Challenge = The Grade II Listed buildings had to be protected from the weather whilst the roofs were stripped and replaced

    Solution = The project was divided into two phases and temporary roofs protected the Grade II Listed Henry Morris building during Phase one and the North Wing during Phase two of works.

    Phase one of works to Sawston Village College, an academy school founded in 1930, began April 2019. Works involved the installation of the temporary roof whilst the stripping and re-roofing of the Grade II Listed Henry Morris building took place. The existing pantiles were re-laid to the front elevation of the building and new handmade pantiles were installed to the back.

    Below the roof, the deteriorating lath and plaster ceiling to the main hall was replaced with new, which included the installation of new laths, scratch coat and a finish of thermalime plaster previously approved by the Conservation Officer. Existing facia boards were replaced and the cast iron gutters and downpipes were thoroughly sanded back to metal and painted. The bell tower underwent extensive repairs to the leaded lights, structural timber and boarding.

    The second phase of works included roof works to the North Wing of the College, similar to the roof works to the Henry Morris building. All roof works and internal decoration was completed in time to hand back to the College for the new Academic New Year.

    Westminster School Extension

    Summary = Bakers of Danbury Ltd are currently building an extension to Westminster School. The extension includes meeting and teaching space as well as offices for school staff. Bakers have completed phases one and two which involved the demolition of the existing building and an archaeological dig. We are currently working on phase three.

    Location = Westminster, London

    Architect = Ptolemy Dean Architects Ltd

    Challenge = Access is restricted due to working on a live school. Westminster School is the only ancient school in London which still occupies its original site. The site of the new extension is very closely surrounded by Grade I Listed buildings, some dating back to the 11th century.

    Solution = Phase one involved the careful demolition of the modern concrete music centre in Little Dean’s Yard. The demolition was carried out carefully to protect the Grade I Listed buildings surrounding the site.

    Careful demolition and breaking out was also carried out on the reinforced concrete foundation to the music center to protect the archaeology below ground.

    During phase two Bakers oversaw archaeological excavations, which were carried out in conjunction with Pre-Construct Archaeology. The archaeological excavations uncovered part of the original kitchen to the Monks Abbey dating back to the 11th century. A section of the new build floor will be cantilevered glass - creating a platform from which to view the archaeology below ground level, which was exposed during archaeological excavations.

    Working under the instruction of Ptolemy Dean Architects Ltd, Bakers of Danbury are currently working on phase three of the project. During this phase Bakers will be using traditional building techniques and materials to create a new build extension. The new extension will be constructed with handmade bricks, reclaimed tiles, lead roofing and handmade timber and lead windows. The extension will house a new teaching/ meeting area and offices for the school staff.

    Bakers will also carry out internal renovation works and external restoration works to a number of surrounding school buildings.

    This project will also include a full M&E package which includes the new build extension and existing school buildings, as well as landscaping to Little Deans Yard, which lays the front of Westminster School.

    Westminster Abbey

    Summary = Roof works to the medieval South Triforium and the Great Cloister within Westminster Abbey.

    Value = Approximately £1,450,000

    Location = Westminster, London

    Architect = Ptolemy Dean Architects Ltd

    Challenge = Access issues and restrictions due to the main access route into site being through the Great Cloister - a busy area of the Abbey accessible to the public from 9.30am every day.

    Solution = Under the instruction from Ptolemy Dean Architects Ltd (Westminster Abbeys Surveyor of the fabric) Bakers carried out roof works to the medieval South Triforium and the Great Cloister within Westminster Abbey.

    70ft above the Abbey floor, the new gallery provides visitors with magnificent views down over the Abbey buildings and the Palace of Westminster. Roof works carried out by Bakers involved stripping the existing roof, recasting original lead and re-leading part of the South Triforium and part of the Main Cloister.

    A full overhaul of the rainwater goods was also carried out, with a combination of new and refurbished lead downpipes, hoppers and chutes fitted. A new hopper, corbel stone and 22 metre downpipe was introduced, formed to mirror the Christopher Wren era hoppers that were already in use.

    Bakers increased the gradient of the Triforium roof by increasing the fall of the lead bays (compliant with lead sheet association guidelines). Other structural repairs included reinforcing 300-year-old oak primary rafters using a flitch plate repair and other associated structural repairs to the oak roof.

    Other works include the provision of a new access hatch and fall arrest system, stone repairs and indents to internal and external elevations and the careful re-homing of monuments and statues from other parts of the Abbey onto the Triforium floor.

    The new freestanding external access ladder with a handrail was crafted from European Oak. It was a good project for our recently qualified joiner Jack Darvill to work on.

    With the improvements to the rainwater goods, Bakers also undertook the renewal of the below ground drainage within the Great Cloister, which will also included the exciting addition of a fountain positioned in the centre of the Cloister, formed on York Stone paving with a lead cistern fountain.

    Works were completed Spring 2018, in time for the opening of a new museum and gallery, located in the Abbey's medieval Triforium. After being hidden from public over 700 years, the Triforium became “The Queen's Diamond Jubilee Galleries”.

    Jim Vincent, Clerk of the Works at Westminster Abbey said:

    Bakers of Danbury have successfully managed access issues and restrictions whilst carrying out the works at the Abbey. The main access route into site is through the Great Cloister, which is a busy area of the Abbey accessible to the public from 9.30am every day.

    We have found Bakers of Danbury to be considerate of the public and employees of the Abbey and have undertaken the works to the Abbey with the utmost care and attention at all times and look forward to continuing our working relationship with them in the future. The high standard of work is commensurate with the status of the building and is what is expected of contractors working at Westminster Abbey."
