About this event

The talk is co-badged with CIHT

The Eastern Bay Link scheme extends the A4232 link road around the southern perimeter of Cardiff from Queensgate Roundabout to Ocean Way Roundabout. It passes through Cardiff docks, providing the next section of the link road and removing the need for traffic to negotiate the current 3½km route via Central Link, East Tyndall Street and Ocean Way.

The Strategic link road is a 1.2km long elevated dual Carriageway and the conceptual design was based on the provision of two approach embankments and a viaduct of composite construction approximately 300m long. Due to the poor ground conditions it was envisaged that the embankments would need to be piled.

Site constraints required a large part of the approach works to be contained by retaining walls. Alteration works including additional signalisation were required to both roundabouts together with diversion of the main dock road.

The main risks were considered to be acquiring the required land, poor ground conditions including areas of contamination, site restraints due to the immediately adjacent CELSA live railway and working dock roads, and phasing of major service diversions.

An ECI contract for the design and construction of the road was let to the Dawnus Ferrovial Agroman JV in January 2015.

Due to technical difficulties with planned service diversions, the Client's conceptual design was fundamentally changed to extend the main viaduct and include two approach viaducts. Issues with the original Environmental Statement and Traffic Modelling resulted in further potential delays to the design and construction.

The speakers will describe how a collaborative approach and the use of innovative solutions enabled these challenges to be overcome resulting in the project being delivered on time and under budget.

The delivery of sustainable community benefits will also be discussed.

Light refreshments will be served at 5.30 before the lecture which starts at 6.00pm.

He is currently an Associate at specialist bridge designers Cass Hayward LLP and has been engaged in the design and construction of bridges for the majority of his 20 years in Civil Engineering.

During his career, Gareth has been involved in the design of many different types of bridges in both the highway and railway sectors. His most prominent projects include the award-winning schemes for the reconstruction of the long-span East Coast Main Line crossing of Newark Dyke and the heavyweight launch of the widened Bishop's Bridge Road crossing over the platforms at Paddington Station.

The Newark Dyke railway underbridge design helped to pioneer analytical methods of addressing the dynamic effects of high speed trains. His more recent design for the Reconstruction of Thorndell Railway Viaduct in Sussex was the winner of the 2016 ICE Designed in Wales Award.

Gareth was the Structures Design Team Leader for Cass Hayward on Eastern Bay Link and was primarily involved with the design of the 230m-long railway viaduct.

His other local designs include cycleway crossings of the River Taff serving the Test Match cricket ground at Sophia Gardens and the Pont y Werin bascule bridge over the River Ely in Cardiff Bay.
