Description Of Works

The Contract involved the installation of 65 no. access hatches and 63 no.ventilation holes to Longitudinal Box Girders at various locations at Gravelly Hill Viaduct.

The forward planning and timely execution of the works were critical as the bulk of the works were carried out using temporary overnight traffic management closures on major Birmingham link Roads and also needed to be co-ordinated in conjunction with  a major ongoing Road Renewal scheme in the area.

The scope of works was complex and required significant technical input from both RH Painting Limited and also Key supply chain partners at both design and construction phase.

Due to the location of the box girders (and the co-ordination required to complete the multiple facets of the scheme) very special consideration had to be given to the effect of the planned works on key stakeholders (including Birmingham City Council, CRT, Utility companies). By sharing the knowledge and experience of RH Painting and Key supply chain partners that had been gained on previous  Hatch installation schemes the contract was completed ahead of the agreed programme and was deemed to be a great success because as well as completing all works specified at pricing stage significant additional works were completed which would not have been possible without the development of both cultural and close working relationships between trusted supply chain partners and our client Amey Area 9 MAC.

A brief description of the works is as follows

(i)    Installation of access hatches and ventilation holes to multiple box girder locations (also testing of welds on completion).

(ii)   Provision of access (via fixed scaffold or MEWP) to allow works to multiple work locations within restricted traffic management working.

(iii)  With reference to the access scaffold all temporary works were designed and completed to comply with an approved RDP (Record of Design Principles).

(iv) Supply and co-ordination of all traffic management to allow completion of the works. This included providing information to the Principal Contractor to allow booking of Road space with Birmingham City Council.

(v)  Preparation and painting of newly installed access hatches and ventilation holes (and surrounding steelwork to existing box girders) with a Type I(M) coating system.
