The project sope

The last upgrade works was in 2014 and currently treats sewage for approximately 4 million customers being the biggest in the UK. The latest upgrade works will ensure the site can treat sewage from up to 4.4 million people and accommodate flows from the Thames Tideway tunnel which is due for completion in 2024. We were engaged by our client to upgrade the security rated fencing on several (9 off) transformer compounds throughout the site.

The solution

Steelway project team worked closely with the client to produce all mandatory documentation, which included a quotation, detailed drawings, a comprehensive program of works, and RAMS for installation. Before the installation took place, Steelway conducted a site survey to gather comprehensive information. This survey covered various aspects such as site access, laydown areas, crane access, and risk assessments.

Within 7-10 days of the initial enquiry, Steelway had completed a full survey of all transformer compounds and issued a final quote for approval of costs. Within a further 10 days, all drawings for approval had been prepared and issued to the client. Once the drawing had been approved Steelway manufactured on all items and completed this within the agreed 5-week manufacturing window.

Full installation immediately followed and was completed in the agreed 3-week window.

Steelway designed, produced and installed a bespoke transformer compound fencing protection solution, customised to the precise requirements of the customer and the unique needs of the site and in the required timescales. Effectively deploying on-site personnel within the client's remit. All goods were safely transported and lifted into place using authorised equipment and procedures, facilitating a secure, efficient, dependable and timely installation
