“Complete cradle solutions”

Background: Our brief was to remove and recycle the old equipment, assess the suitability of the existing track and design, install, test and commission a replacement building maintenance unit.

Results: 40 Melton Street also known as Railtrack House is 16 floor building adjacent to Euston Station in Central London.

The exterior consists of a mixture of glazed and black granite cladding panels, these being maintained using the buildings dedicated building maintenance unit. This 30 year old unit had reached the end of its design life and as with most equipment of this age the cost of the year on year maintenance was increasing as parts were changed due to wear and tear.

In 2009 the decision was made to replace the existing BMU and PTSG Access and Safety was tasked with providing the new machine. Part of the PTSG Access and Safety remit was to assess the suitability of the existing track. A detailed survey and program of testing was under taken including testing the thickness of the CHS track with ultrasound, MPI testing all the track welds for cracks and testing all the HD units for corrosion. On receipt of the positive track survey results work on the design of the unit could begin and a detailed programme of works was agreed with the client.

One of the main obstacles still to be overcome was the positioning of the mobile crane for the removal of the old equipment and the installation of the new machine. The obvious solution was to site a smaller crane closer to the building on property owned by Network Rail reducing the client costs and removing the need for complex road closures. This however provided its own sizable problem as directly below the crane position was Network Rail’s own underground car park and the work area above ground provided a very limited area in which to work. Following detailed topographical and structural surveys, the final positions of the crane outriggers were determined and structure analysed to allow the car park below to be back propped using ‘super-props´ with SWL of 12 tonne.
The building situated adjacent to Euston Station has a very high foot fall during the week and after carrying out a detailed risk assessment the decision was made to carry out the works over a weekend when passing pedestrian and vehicular traffic was at its lowest, reducing the risks associated with the works significantly.

On a Saturday in March 2010 the old unit was removed for its final journey to the recycling facility and the new unit supplied by our partners GinD was successfully installed on the building. Over the remainder of the weekend the unit was tested and commissioned and in April 2010 it was inspected by HSB Haughton and put in to service — its first task to clean the windows.
