A new industry Code of Practice for Ironwork Systems Installation and Refurbishment has been published by the Road Surface Treatments Association (RSTA). It forwards industry best practice and has been peer reviewed and endorsed by Highways England and ADEPT.
The Code provides practical guidance on how to avoid early life failure, how to achieve a high quality installation and ensure a high quality repair. It covers installation and refurbishment of ironwork systems including gulley tops and chamber covers. The Code cross references HA104/09 Chamber Tops and Gulley Tops for Road Drainage and Services: Installation and Maintenance in the Design Manual for Roads and Bridges. It also cross references the Specification for Reinstatement of Openings in Highways (SROH).
The Code aims to increase the average service life of ironwork installations and refurbishments by illustrating a ‘right first time’ approach using appropriate materials and good design, which when combined offer lowest whole life cost. Currently the service life expectation and specification guidance for the installation and refurbishment of ironwork varies greatly from location-to-location and between clients. Furthermore, guidance often covers products and components in isolation. The Code considers all aspects of installation and maintenance, including potential areas for failure. It consolidates existing industry experience into one document offering comprehensive industry best practice. Particular advice is given for brickwork supporting the frame and cover, bedding mortar selection and backfill selection around the ironwork installation plus surfacing and over-banding around the ironwork installation.
The health and safety, environment, training and quality assurance responsibilities of client and contractor are also set out by the code. It also provides guidance on site planning, programming, co-ordination and traffic management. A useful inclusion is the pre-contract, on-site and post-contract check-lists.
