Damboard Replacement Project - Re-design of Stop Log support structures

This contract serves as an exemption and is outside of normal HBC Contract Procedure Rules. The Damboard Replacement Project began in 2021 and original optioneering was carried out by Beckett Rankine. Beckett Rankine completed a detailed design in 2024 and it was recommended to carry out Ground Investigation work. This was delayed until 2025 as the estimate for the cost of the stoplogs was well in excess of the available budget and a decision by the board was needed to re-establish the project strategy. Following the completion of the ground investigation work it was proposed to appoint marine engineering consultants to advise on a pre-construction agreement process, but the projected costs combined with a reduction in the budget meant that the majority of the revised budget would be spent on fees. As it is now proposed to carry out soft market testing of the stoplog solution, it is necessary, in order to obtain accurate and reliable estimates from contractors, to have a detailed design that could be implemented as otherwise the estimates will be subject to too many caveats and assumptions to make them worthwhile. As Beckett Rankine have carried out all the marine engineering consultancy and design work on the project to date they are in a position to carry out the design amendment work most cost-effectively and rapidly.
