Internal Plaster: Survey, Recording and Specification

Lincoln's Inn Chapel, London

The interior of the seventeenth century chapel of Lincoln's Inn was recently subject to an extensive refurbishment. A substantial part of the work was re-plastering of the internal brick walls. Ingram Consultancy acted as specialist advisor on the plasterwork from survey stage to completion of the refurbishment, with the following general scope of work:

• Survey - Prior to carrying out any re-plastering work an investigation of the plaster was necessary to establish the plaster condition, composition and chronology. Part of the brief was to satisfy English Heritage and other parties involved that the plaster was not original and that defective plaster could be removed in preparation for re-plastering. This included examination of the plaster layers by opening up 'windows' at selected locations. This initial investigation was essential for obtaining listed building consent for re-plastering.
• Specification - A detailed specification was produced for all work to the plaster, including the removal and recording of later plaster layers, and re-plastering.
• Supervision - Ingram Consultancy provided supervision throughout the contract period and issued instructions to the contractor as necessary.
• Recording - The existing and obviously recent plaster finish coat was carefully removed to reveal undercoats. The undercoats were recorded on drawings indicating any features, such as mechanical key, supports (tiles, tile pieces and lath), and defects, mainly cracks and areas of detachment.
