Structural and Civil Consultants worked for Bourne Engineering Ltd to provide steel to steel connection design for the new western ticket hall at Farringdon Station in central London.

Farringdon station is undergoing a major redevelopment to increase capacity, improve accessibility and upgrade interchanges as part of the building of Crossrail.

The western ticket hall at the corner of Farringdon Road and Cowcross Street will integrate with the Thameslink ticket hall. As part of the development, the new western and eastern ticket halls will also be connected by 250 metre-long underground platforms.

Compilation of Repair Schedule for the purchaser. This end cottage on the sea front was built into the cliff face and appeared to have a history of structural distress. The end gable in the photograph is being supported by raking props.

We prepared an alternative design for the Fabricator which gave a considerable weight saving over the design proposed by the Client Engineer and enabled him to win the contract. The portal frame element contributed 90% of the steel weight but only 10% of the design effort.

We are aware that steel fabricators are having difficulties with the design of elements and connections to the Eurocodes. Some fabricators continue to use their BS5950 based software or the green book to design their connections when the frame has been designed to EC3, reasoning that the Eurocode is based on the same principals. We have found that this approach is not always accepted by the Engineer.

We have invested in software and have written spreadsheets ourselves so that we can offer our services for the design of connections or whole frames to EC3.

Recent projects include steel connection design to BS EN 1993-1-8:2005 for two new schools in England, including an interesting combination of steelwork and precast concrete frames.

We have also carried out design checks on existing highway structures in France and England to take additional loading, as well as the design of an industrial steel framed tower (far left).

The unique way that the Eurocodes have been compiled with multi-national cooperation now means design of a structure abroad can easily be carried out, simply by applying the parameters from that country's national annex.

Slabs were cast to form the future roof of the underground station. This station was one of the first to be designed under new legislation following the Kings Cross Underground fire, sufficient headroom was required for smoke extraction to enable a train to burn safely at the platform.

Enabling Works for a future underground metro station beneath the new bus station involved creating retaining walls using contiguous augered piles. Isolated piles were installed to become future columns along the platforms.

 

                           

 

Beams up to 3m deep were cast to span between columns and across  the future tracks.

Lines of contiguous augered piles were connected at the top with deep concrete beams. These formed the load bearing retaining walls of  themetro station and track. The roof slab was cast across the top between the two lines of piles.

  

 

 

The detailed design for the Enabling Works was carried out under a design-and-build contract that enabled us to concentrate on the detailed design of the bus station structures above (see sheet 2 of 3). Construction of the bus station commenced as soon as the enabling works were complete.
