London SW9

Background

Managing the entire process of delivering and installing two new 30te 16 MVA, 22/11kV transformers for the Northern Line power upgrade project in a challenging location in central London was no small feat. Such projects require meticulous planning, coordination, and execution to ensure success, especially in urban areas with logistical challenges.

Being appointed by Balfour Rail and showcasing our capabilities as a trusted subcontractor has further solidified our reputation in the industry. Our in-house team’s training and certification in areas such as safe handling, confined spaces, and abnormal loads highlight your dedication to safety and quality in every aspect of the project.

Such accomplishments not only contribute to the improvement of the TFL network but also establish Radius Group as a reliable partner for future projects. Your track record of successful deliveries speaks volumes about your capabilities and expertise. It’s evident why clients should entrust their projects to your team, knowing they will be handled with professionalism and efficiency.

Challenge & Solution

From the initial site survey, we worked closely with our client to produce detailed AutoCAD drawings, outlining each step of the delivery, with millimeter precision. Once we had the solution, we produced a delivery programme and managed every step of the process from concept to completion. Radius provided all the detailed planning elements, complete with the risk assessment & method statement, fulfilling the duties under LOLER1998 & BS7121-1+3 to ensure all deliverables were on time, within budget, and delivered safely.

We were faced with numerous site constraints and had to find bespoke solutions for each individual 30te transformer from OEM (Brush Transformers) to deliver it to the final assembly position on site. The first transformer was installed to a temporary raised foundation, which entailed collection from the OEM factory and road transport to site. Radius provided a full CPA Contract Lift for using a 200te mobile crane with Chapter 8 Traffic Management, local authority liaison for all required parking suspensions and full road closure.

Horizontal load transfer along 100m narrow roadway utilising a 120te Plant Roller, uplift and positioning to foundation by 80te Hydraulic Gantry Lift System. Radius also provided forklifts and in-house experienced teams to assist OEM with the final assembly of components for Site Acceptance Testing (SAT). The second transformer was skidded into the pen via our 350te Hydra Slide Skidding system. Again, our site teams provided all the handling for the site assembly of the transformer by OEM. The final step, was to relocate the first transformer from its temporary location to its new pen, again easy work for our in house specialist plant handling equipment and site teams.
