As client project manager for both the Glynn Vivian Art Gallery and The Guildhall Swansea, I found working with JWC a real pleasure. In my experience, JWC work collaboratively with the client team, design specialists and the wider supply chain in a professional and proactive way so as to minimise potential cost, quality and time issues during construction. I have found that their approach to change none adversarial and as for problem solving of difficult buildability issues on site, this has been second to none especially on projects of an historical, listed buildings nature. I have also found the finished product to be of the very highest quality.
John Weaver Contractors delivered a very high standard of services, on this difficult and fast paced project. Phasing works around the needs of patients on an almost room by room basis, the site works team performed exceptionally well and maintained very good relations with patients and Ward staff at all times.
