Dulwich College

Client: Jones Lang LaSalle
Principal Contractor: PAYE Stonework & Restoration Limited

Built between 1866 and 1870 the Grade II* Listed buildings are of significant architectural interest constructed from loadbearing masonry using brickwork, decorative terracotta and Portland stone.

 

In order to maintain and return the facades to a good state of repair an extensive external programme of works is taking place to conserve the masonry, windows and roofs.

 

The college remained fully occupied and operational throughout the life of the contract.

 

SCOPE OF WORKS
The specification and scope of works was developed during a series external surveys and inspections carried out from a combination ground level, mobile vehicle platforms and roof access.

 

The information was used to produce highly detailed elevation drawings indicating the extent and location of work to be carried out together with quantified schedules of repair.

 

The scale and volume of enriched, intricate architectural detailing that embellishes the facades may not always be fully appreciated from ground level but it’s this attention to detail that make the buildings historically important and all the more worth conserving for future generations.

 

The majority of the repair work was concentrated at roof level on Central Block which includes the brick and terracotta turrets, finials and pierced terracotta balustrade that follows the complete perimeter of the building.

 

Terracotta has become at risk from fracturing caused by corrosion of embedded metal dowels and restraint bars. In order to repair and make these safe the features were carefully dismantled salvaging where possible for re-use.

 

Replacement terracotta was manufactured following traditional techniques using relevant examples taken from site used as models to form plaster moulds. Where this was not possible, clay models are hand crafted from detailed drawings and site profiles.

 

The rebuilt terracotta was constructed using stainless steel to prevent future corrosion and damage.

 

Additional work included tuck pointing brickwork, brick replacement, stone repairs, roof repairs, window repair and decoration.
