Walker Sime

What Walker Sime does

Walker Sime is a UK-based multi-disciplinary construction consultancy founded in 1999 and headquartered in Manchester, delivering quantity surveying, project management, employer's agent, bills of quantities, CDM advisory, PMO, and regeneration delivery services. Its portfolio spans real estate development, regeneration schemes, and infrastructure projects — including the £5 billion 30-year Liverpool Waters programme, Forth Yards (£200m), One Medlock Street, New Bailey residential towers (£63m), and multiple NHS, higher education, and nuclear sector facilities. The firm operates from five UK offices (Manchester, Liverpool, Leeds, London, Middlesbrough) and is part of the HanmiGlobal Group, which provides international reach across 66 active countries through 13 global entities.

The business model is a professional services consultancy with quote-based engagement, revenue derived from fees on QS, PM, CDM, BoQ, and Employer's Agent mandates delivered to enterprise developers and public sector clients. Go-to-market combines direct relationship-led sales with framework agreement participation (TfGM Professional Services Framework, Procure Partnerships Framework) and active event-driven positioning (UKREiiF Official Partner, RICS Matrics Awards). Customer base is split between private developers (Peel Holdings, Bruntwood, Muse Developments, Ask Real Estate) and public sector bodies (Manchester City Council, Bolton Council, TfGM, Manchester University NHS Foundation Trust).

Operationally, the firm has scaled from a two-person founding team in 1999 to a sub-100 employee consultancy with 3,174 completed projects, growing through acquisition (WCP Associates, July 2019), geographic expansion (Liverpool office 2018, London and Middlesbrough additions), rebrand (January 2021), and senior leadership reinforcement (Peter Jackson, Gareth Robertson, Sheryl Durham joined 2024-25; Jon Neville appointed MD February 2025). The firm holds RICS Conflict Avoidance Pledge and Positive Planet net-zero accreditations and serves eight of the top ten UK contractors through its Bills of Quantities service. No proprietary technology platform, AI/ML capability, or software product is offered — services are delivered by RICS- and NEC3-qualified personnel using traditional consultancy methodologies.
