Design and checking of major temporary works associated with the lifting of the arch sections and launch of the deck.

Design and checking of temporary works used during the reconstruction of the existing highway bridge over 7 rail lines.

The novel erection scheme involved construction of the new deck above the existing bridge and removal of the existing deck on underslung runway beams. Finally the bridge was jacked down 3m using Powerlift units during short overnight rail possessions.

Design of modifications widening the link span and allowing the use of larger ferries.

Design of spreader beams to enable the 3 main girders to be lifted as a four point lift.

Design of 17 footbridges which replaced existing level crossings over the main line.

Project management for design, procurement, shipping, and erection scheme details.

Supervision of temporary works design for launch of bridge steelwork.

Sales Director for Fairfield-Mabey during award of subcontracts for structural steelwork. Closely involved in Hochtief’s tender team for the Marsh Mills slip roads slide-in.

Conception of erection scheme using floating crane to lift beams into place during night time occupations of the Docklands Light Railway.

Commercial Manager at Fairfield-Mabey responsible for estimating and negotiation of steelwork subcontracts.

Relocation of dockside crane using wheeled transporters and military trestling.

Site Agent for Major Maintenance Contract which included measurement of hanger loads, changing hanger pins, upgrading gantries and accesses, concrete repairs, and blast cleaning and/or painting the entire structure.

Design of temporary works comprising panel (Bailey type) bridge sections and military trestling. These supported the rail tracks and slide path during the bridge slides.

An unusual aspect to the scheme was the use of 61m span trusses to support the rail tracks during ground excavation. The trusses comprised 1.5m deep standard panel bridge components which were supported on railway wagons, preassembled and delivered from a rail yard several miles away.

Analysis of the geometry of the cables and deck for both the permanent works and during the construction phase. The analysis of geometry during the construction phase was a complex process which required the use of a non-linear plane frame computer program to model the cable geometry and gaps between deck boxes.

Design of temporary works for the tower top platforms, deck lifting attachments, and a temporary bridge over the main line railway used to support and transfer the deck sections prior to lifting.
