The Yorkshire & Humber Awards: Winners and highly commended

We reveal the winners of the 2010 Yorkshire Award for Excellence.

Winner:

A6102 Storm Damage Sites

Storm damage site

Work underway at the A6102 Middlewood Tavern

The A6102 collapsed in two locations alongside the River Don during the June 2007 floods, severely disrupting transport and primary services.

The innovative alternative solution developed by WYG consisted of an insitu concrete piled river edge with a reinforced concrete capping beam and rock armour protection and a reinforced soil slope above, supporting the reconstructed road and footway.

The road collapse threatened major 838mm and 914mm diameter water mains and a 228mm diameter gas main located in the road. Emergency diversions and isolations were needed for traffic on this main road and the strategic services within it until the collapsed sections could be rebuilt.

Reconstruction of the highway was challenging, with the road following a narrow ledge of the river valley wall with steep, heavily vegetated slopes down to the River Don

“The delivery team had the courage of their convictions to adopt and implement a solution which was untraditional in approach”

Judges’ comment

The project team had to maintain some access at the crest for pedestrian/cycle traffic, protect the strategic services now exposed on the surface, and avoid narrowing the river channel at any time.

A speedy solution was essential with the slope deteriorating slowly threatening further failures, yet the highway still needed to be rebuilt with a 120 year design life.

It was recognised early in the project that full engagement between temporary works and the permanent works designers was required throughout the design and construction process to continually assess and balance often conflicting requirements.

Judges’ comments

“The delivery team had the courage of their convictions to adopt and implement a solution which was untraditional in approach.

“The solution, which required an amalgam of temporary and permanent works within a very tight working corridor adjacent to the River Don, not only minimised the environmental impact on the river corridor but resulted in a robust cost effective solution with minimum disruption to the public.

“This is a project which clearly demonstrates the commitment, perseverance and skill of civil engineers in addressing those challenges which our communities face.”

Medge Hall track stabilisation

Medge Hall track stabilisation

On the face of it a 500m long piled slab constructed on a flat site to a single level and on a straight line does not sound like particularly challenging. But the site location, ground conditions and timescales allowed for the works posed significant difficulties for the project team charged with stabilising two rail lines crossing a peat bog near Crowle.

The fact that the design, temporary works, construction sequence and methods adopted would be key to the success of the project was recognised by Network Rail, which decided to let the scheme as a design and build project.

The Grontmij design team worked with the Carillion temporary works designers and the team which would deliver the project to identify project risks and constraints.
Permanent works involved 1,250 piles, earthworks, and the construction of the slab itself.

Judges’ comments

This was a project that was “challenging in the extreme”, with the task of stabilising a railway line crossing a peat bog, at a remote location, on a site bounded by a canal on one side with a wide land drain on the other.

“The delivery team successfully overcame these engineering and logistical challenges to deliver a project of which they can be extremely proud,” they said.

Highly commended:

Esholt Wastewater treatment works FFD scheme

Water is a major spending sector in Yorkshire and Humber

Esholt Wastewater Treatment Works Freshwater Fish Directive (FFD) scheme represents an excellent example of a complex civil engineering project which demonstrates a very high standard of design and construction.

The Esholt works treats wastewater from Bradford and North Leeds, with a population equivalent of 730,000 and peak inlet flows reaching 13.5m3/s.

The FFD imposed a tightened ammonia consent from November 2009, which required Yorkshire Water to invest £75M in substantial improvements and upgrades.

These comprise improvements to the inlet works, a hydroturbine, replacement primary settlement tanks, an activated sludge process and additional final settlement tanks.

Sludge treatment systems comprising thickening, anaerobic digestion, combined heat and power (CHP) engines and sludge phyto-conditioning areas have also been constructed. Overall the design has centralised assets within the site, cutting the operational area by over 30ha.

Judges’ comments

The judges said the culmination of many of years of hard work has resulted in “Not just another wastewater treatment works” but a project that has been extremely well planned and executed with significant benefits for all stakeholders and the environment.

Highly commended:

Leeds Inner Ring Road stage

Leeds Inner Ring Road

Road Stage 7 project (LIRR7) provides the final link to connect Stage 6 of the scheme (completed in 2000) to the M621 and the wider nationalmotorway network. Construction began in May 2006 and was completed in December 2008.

It involved the construction of dual two and three-lane carriageways, through a previously industrial area, with slip road links to the M621. It includes a 600m long viaduct over local roads and three bridges over the Leeds-to-Castleford railway.

The design and construction of the project was begun by Leeds City Council via a two-phase process involving an Early Contractor Involvement (ECI) contract that was awarded to Alfred McAlpine in March 2005.

Phase one, which began in April 2005, involved detailed design. The construction works started in May 2006.

Judges’ comments

The judges said the project used an innovative procurement process with a genuine sharing of risk and benefits amongst all the parties; from feasibility through to construction.

East Riding flood alleviation scheme

East Riding flood alleviation scheme

In June 2007 the East Riding was hit by unprecedented rainfall causing extreme flooding.

Over 6,200 properties were flooded along with 12,400ha of agricultural land and 722km of highway, costing council and homeowners in excess of £250M.

The council approved a oneoff allocation of £500,000 to help tackle the aftermath. A further £4M was awarded to the council from the government’s Flood Restoration Fund.

The restoration fund was invested primarily in repairing damage to the highways infrastructure and to build greater flood resilience into the East Riding’s infrastructure. It also covered repairs to damaged infrastructure and reduced the flood risk or impact to the communities in the East Riding.

Judges’ comments

The judge’s said there was a great willingness to experiment and learn by doing. “The client delivery team was willing to risk face to face community engagement and work at the limit of its comfort zone to deliver low cost, locally effective and potentially sustainable flood management.”

A1 Bramham to Wetherby upgrading

East Riding flood alleviation scheme

An early contractor involvement project which involved the Highways Agency, Balfour Beatty and Atkins, the scheme involved upgrading 10km of the former A1 trunk road to motorway status.

This included widening 3km of the former dual twolane all-purpose A1 around Wetherby to dual three lane motorway standard.

A new bridge over the River Wharfe was constructed for the southbound motorway carriageway with the existing River Wharfe bridges modified to carry northbound traffic. Two more new bridges have been constructed over the A1 at Wetherby Grange and Walton Road.

Judges’ comments

The judges’ said the project marked the culmination of more than a decade of major highway improvements in Yorkshire, demonstrating effective design and construction. “The delivery team took the opportunity of promoting, designing and delivering a project that would not only benefit motorists but would also benefit the local community,” they said.
