Scope and significance of project:

As part of the Royal National Lifeboat Institution (RNLI) Framework, RNLI St Davids was the last of eight Tyne class lifeboats stations around the UK to be replaced or significantly modified in order to accommodate the larger, more advanced and faster £2.7m Tamar class vessel. The collaborative team work and accumulated knowledge and expertise generated between the RNLI, their designers, consultants and BAM Nuttall, as remaining sole principal contractor, has resulted in BAM Nuttall successfully completing approximately £75m of work for the RNLI over the last ten years. St Davids was the last of Tamar stations to be constructed because the RNLI and their consultants regarded it as the most challenging one of all. The station is situated in a rocky cove at the base of a 200ft cliff, just south of the old station. Access to the logistically remote location was further hindered by restricted narrow lanes regularly used by holiday makers.

Please detail how you demonstrated collaboration on your project:

Building on accrued knowledge, expertise and trust accumulated over the 10 years of the framework, collaboration continued to an even greater level at St Davids due to the extreme complexities faced and the opportunities afforded by technology and the contract. As on previous projects, BAM Nuttall’s Early Contractor Involvement (ECI) and committed one team approach generated specific engineering solutions in addition to previous ones like using a bespoke BAM Ritchies RH600 drill rig on a jack-up barge. To reduce the cost of jack-up barge use, BAM Nuttall had suggested that the RNLI takeout a long term charter which resulted in a cumulative saving of £810k with £212k having been saved specifically at St Davids. The mutual trust between the framework entities was illustrated at tender stage of St David’s. Our BIM model picked up a clash between the boathouse piles and the cove cliffs. BAM Nuttall generated a series of different designs and priced each design to keep within the budget.

These included a radical final ‘V’ column design that was agreed and accepted by all. At St Davids collaboration generated open and trusting relations between all parties. In particular, the NEC3 option A activity schedule was produced using rates and prices that were checked against the open market. As a priced open book the RNLI could see exactly what we had priced and was checked against the budget by the employers cost consultants, McNaughts. Instances where the budget was overtopped stimulated intense efforts to further value engineer solutions that met the remit of all parties.

From the outset this approach promoted a stable co-operative interface founded on mutual trust. Specific value engineered or new innovative solutions generated at St Davids included, using a redundant shipping container to dam the rocky cove. This reduced the impact of bad weather and created extra dry space time and equipment did not have to be lifted to the cliff top after each low tide. This saved over £100k pre-contract. The trust and confidence of the RNLI was never taken for granted and the team continued to use every opportunity to enhance and strengthen relationships. For instance, knowing that the RNLI wished to use BIM on their future projects, the BAM team arranged for RNLI personnel members to attend BIM Awareness course organised through the BAM Nuttall training department.

The knowledge the RNLI gained including asset management has been applied to their projects at RNLI Swanage and Scarborough. Use of BIM, iPads and a cloud based database provided accurate and timely information shared and used collaboratively among the team, including with permanent and temporary designers who worked remotely. St Davids is due to be completed in July 2016.

It is calculated that the collaborative framework with the RNLI will have generated at least £2.7m in direct quantifiable savings. Such beneficial financial savings have been possible as a direct result of BAM Nuttall’s willingness to promote and take part in a collaborative approach to successfully delivering world class civil engineering projects like RNLI St Davids.
