What Pre-Construct Archaeology does

Pre-Construct Archaeology (PCA) is a privately held UK professional services firm founded in 1993 that delivers archaeological and heritage consultancy to development and infrastructure projects. Headquartered in London, the firm operates from seven regional offices (Cambridge, Durham, London, Newark, Norwich, Warwick, Winchester) and employs between 101 and 250 people. PCA's core offerings span the full project lifecycle: heritage consultancy (pre-planning advice, desk-based assessments, environmental impact assessments, building assessments), archaeological fieldwork (evaluation, excavation, watching briefs, monitoring), surveying (archaeological, landscape, drone/UAS, laser scan), built heritage recording, post-excavation analysis, and a publishing programme (PCA Monograph Series, Booklets, Occasional Papers). Notable technical capabilities include CAA-authorised drone surveys producing georeferenced 3D models and orthographic maps, laser scanning, in-situ photogrammetry, and Reflectance Transformation Imaging.

PCA monetises predominantly through quote-based professional service fees for consultancy and fieldwork, supplemented by unit-priced monograph sales (typically £13.50-£36.50). The firm is sales-led, distributing directly through its regional office network to private developers, infrastructure companies (renewables, road and rail), local authorities, heritage organisations, and private homeowners. The company is privately held with no disclosed institutional ownership and underwent an amicable management takeover in 2025 effective 1 January 2026, with founders Gary and Josephine Brown retiring and the remaining directors continuing to lead the business. PCA holds the regulatory and quality accreditations required to bid on major UK public-sector and infrastructure tenders, including CIfA Registered Organisation status, ISO 9001:2015, ISO 14001:2015, Constructionline Gold, and Achilles UVDB Silver Plus. Notable client engagements include Historic Royal Palaces (Tower of London Chapel of St Peter ad Vincula excavation, broadcast on Channel 5), Hass Homes, Terence O'Rourke, and Westminster Abbey.
