Kings Bridge Strengthening, Huddersfield

This was an interesting project to reconstruct the deck of an attractive Victorian cast iron bridge spanning the River Colne cater for modern highway loading. The bridge was reconstructed in 2 halves and the carriageway was reduced to 1 lane and signal control introduced with occasional weekend working for critical operations.

To maintain the attractive appearance of the bridge, the cast iron edge beams were removed and refurbished, then replaced along with the new precast prestressed concrete beams installed to carry the heavy loads. Close liaison with the Highways Authority, Environment Agency, Statutory Undertakers and the Clients design team ensured the smooth progress of the scheme. We also developed the diversion routes and managed these and the signage during the progress of the works.

Fenay Bridge, Huddersfield

A new highway access bridge with spread footings and precast prestressed concrete infill beams across an attractive trout stream. The bridge was commissioned to gain access to an isolated section of land identified for residential development. A measure of our environmental performance is that trout were quite happily leaping in the pool adjacent to the works.

Newark Footbridge

We were originally commissiond by the Project Managers, on behalf of the Client, DSG Retail Ltd (Dixons) to provide an attractive concept solution with budget estimates for this project. The bridge carries a footway/cycleway linking Newark town centre with the new industrial estate adjoining the A17 and crosses the A1 southbound slip road. The works included reinforced concrete spread footings and piers, with pre-fabricated steel truss and bowstring girder deck spans. The deck spans were assembled on site and lifted into postion during a weekend overnight possession. A feature of the pier construction was the use of the patented Peri formwork system.

Stapleford Footbridge

The footbridge links 2 parts of Stapleford School across the A52 in Nottingham. The brief was to replace the P4 pedestrian guardrail with a higher one to make it safer. NMC identified that the proposed shuttering system was too heavy for the deck and re-designed the shuttering to avoid over stressing the deck during the temporary works.

MAC7 Pier Strengthening and Deck Refurbishment Programme

We have an ongoing programme of bridge impact strengthening and refurbishment as part of our MAC7 Trunk Road maintenance programme for the Highways Agency (see also the highways section). Examples are:-

A1 Grantham Bridges

The construction of reinforced concrete collars around the existing piers to increase their resistance to impact loading. The ongoing programme of these types of works gives us the expertise in house of working in the operational highway in a trunk road environment.

A38 Alfreton Footbridge

We carried out a recent unusual project to both provide pier strengthening, raise the deck level to avoid high vehicle impact and refurbish the deck. We helped to minimise congestion to the travelling public which would have been caused by carriageway closure for some months by removing the deck. The deck was lifted by the largest mobile crane in the UK and taken under police escort overnight to our yard 5 miles away tto be refurbished. The pier strengthening and raising works were then carried out under lane 1 closures and the deck then returned under another overnight closure.

M1 Junction 25 Bridges

The raking columns on these bridges required complex formwork and steel arrangements to cast the strengthening beams around the foot of the columns.

Nottingham Southern Relief Route Bridge Widening

This complex inner city junction was upgraded to facilitate traffic flows outside Nottingham Midland Railway Station.

The works included:- Widening of an existing railway bridge approach over an operational railway line; Insitu concrete bored piled foundations; Reinforced concrete bases and piers; Insitu concrete deck; Parapets; Waterproofing; Deck joints; Liaison with Railtrack; Upgrading of a traffic signalled junction; Associated amendments to carriageway layout; Dealing with existing services; Street furniture and street lighting.
