BAE Govan

Careys were engaged to undertake the construction new assembly hall for BAE systems at its shipyard which involves the conversion of the current wet dock to a dry dock facility for frigate manufacturing. Our works includes the construction of RC slabs will be supported on PCC driven piles. The slabs are designed at a depth of 1500mm (external) and 800mm (internal). 1000mm thick 10m high RC walls will be constructed on the East and West elevation of the development, which will support a steel framed roof. We have also installed steelwork connections, drain runs and construction of capping beam.

Our quality record has been exceptional. A small number of NCRs have been discussed, agreed, and repaired with minimum impact to works. However, we have installed hundreds of sets of bolts within RC slabs and walls with no defects and therefore no impact to the steel erectors programme. Our RC sub and superstructure works are within strict tolerance and finish specifications and have been delivered to a high quality throughout the project. Our safety record has been top class with only one accident to date and there has been no lost time on the project. We have maintained an excellent safety approach and culture on site through planning and coordination with our site teams. We have used critical task meetings and weekly blackhat meetings to our advantage on site to maintain high safety standards and set an example for other contractors on the project.

All RC elements were thoroughly inspected at least one day before pouring and signed off. This required an experienced, well-resourced engineering team on site to meet expectations. We adhered strictly to specifications and checked rebar against site drawings in keeping with AECOM requirements (clients site engineer).

We used Motocut for cutting PC concrete piles which is new plant that we hadn’t used before. Familiarisation training and onsite workshops with the team to understand methodology and outputs required.

Volume of deliveries and ‘Just-in-time’ deliveries Daily/weekly meetings with key blackhats, engineers and management to discuss key dates for the project and prioritise deliveries for each aspect of the works.

Interface with Severfield in 2024 Same as piling contractor. Daily coordination meetings and just making sure we enforce our values and our works on site safely. If something doesn’t go to plan then MCLH needed to be notified to make sure everyone can achieve their programme works safely and timeously.

The volume of cast-ins and plates on the 10m walls required strict adherence to high standards during cast-in and formwork installation and concrete pouring, with close collaboration with engineers. As-built surveys were conducted immediately after the concrete pour and submitted to the client. Our ITP ensured compliance with tight tolerances (+/- 2mm). For the North Quay drainage and RC capping beam at the waterfront, we managed tidal works, as River Clyde levels can fluctuate over 5 meters in about 6 hours. We planned resources around tide forecasts to maximise work time while maintaining an aggressive schedule for our client.

Daily co-ordination meetings with all other contractors and setting up our own work with exclusion zones and site set up as per Careys visual standards assisted with this interface.
