Lagan Weir Construction completed 1994 The structure provides water level control for the tidal River Lagan. The weir consists of five hydraulically operated fish belly gates, each 20n long and 5.5m high. The structure has been recently completed through the first major maintenance with repainting of the gates and M&E upgrades. There are plans to replace the walkway with a more architecturally significant structure and (c) URS may be ongoing at the time of the visit.

3 Lagan Weir Visit

The Lagan Weir was key to the redevelopment of Belfast’s Laganside Area.

The Weir was originally designed by Ferguson McIlveen (now part of URS) and was constructed in the early 1990s and formally opened in 1994. The structure provides water level control on the upstream impoundment and protection against downstream extreme high tide events. Maintaining the river level avoids the exposure of the river bed at low tide and ensures a water depth suitable for various recreational pursuits in the river.

The weir structure consists of five hydraulically operated fish belly gates, each 20 metres long x 5.5m high and operated by a single hydraulic ram at one end of 250 tonnes capacity.

The gates are sealed rigid steel protected with an epoxy paint system. The single hydraulic cylinders incorporated rams which were coated with a form of ceramic coating to maximise cylinder seal wear in a saline environment.

At the time of original design the coatings and control system operating the gates were state of art however being in the saline conditions resulted in gradual deterioration of both gate coatings and the surface coating on the ram rod. This caused wear on the cylinder seals and the gradual increase in leakage rates into the adjacent marine environment.

Having carried out the condition report on the structure, URS were subsequently appointed to develop the report recommendations to detailed design level, appropriate to procurement of specialist M+E contractors.

Contract documentation was produced and a two stage restricted list process managed to ensure experienced contractors tendered for these specialised structures. The procurement followed stringent government guidelines and assessed bidding consortium as a weighted quality/cost relationship, including interview stage. URS made recommendations as to the contractor appointment and subsequently managed the refurbishment contract, including detailed technical supervision on site.

A very important element of this construction management was ensuring clear understanding and involvement by the client to ensure all operational constraints were incorporated in methodologies and programmes.

The site works included use of 18.2m long stoplogs, designed to be used on the Ramsome and Rapier gates on the Bann River, to allow isolation of the gates for detailed cleaning, assessment, testing and refurbishment. Gates were repainted in cofferdam conditions and controlled encapsulated environments, with the cylinder rods replaced with a new and improved form of ceramic coating. The project was completed early 2011 and was on budget and time.

The visit will set out a detailed explanation of the refurbishment contract giving an explanation of the gate, cylinder and control systems upgrades.

Titanic Pumphouse http://www.titanicsdock.com/

Nowhere else on earth can bring you this close to Titanic – the world’s most famous liner, built in Belfast. She sat here in this very dry dock on the eve of her first and last voyage in April of 1912. Titanic is remembered for the dramatic story of her sinking, but in 1912, she was an icon for all that was great about the 20th century – she was the most innovative, the most luxurious, the most awe-inspiring thing ever created by the hand of man.

Here, in the shipyard where she came to life, you can still see the remnants of engineering brilliance that brought Titanic into being.

Located in the Science Park – a 21st century icon of innovation and forward thinking – Titanic’s dry dock is the physical reminder of a bygone age in which the dreams of men soared to new heights. Inside the pump-house, the engineering achievement of the Edwardian age is almost perfectly preserved. Amongst the massive pumps and gargantuan hydraulic accumulator, you can still hear the echoes of the men whose labour built the world’s largest ships.

At Titanic’s dock, you have a unique opportunity to explore the site where Titanic last rested on dry ground and absorb the authenticity of her physical footprint in history. What else could compare to standing where she stood on the centenary of her birth?
