Project Description

CLIENT: Trafalgar Wharf Group

PROJECT: DryStack Roof Replacement


SMD are proud to be resident surveyor for the Trafalgar Group. The Trafalgar Group is a young, dynamic group of businesses operating in the leisure boating, commercial shipyard and property sectors, based at the top of Portsmouth Harbour. Trafalgar DryStack offers secure, weatherproof shed, dry stack boat storage for boats, which are lifted and stored on vast boat racks. With dry boat storage for over 300 powerboats, Trafalgar DryStack is the largest boat storage facility in Hampshire and the UK, and possibly in Europe.


We provided Contract Administration and Quantity Surveying Services for the replacement of the roof of the DryStack. Marine environments are challenging all year round, so the selection of the correct materials is key.

Project Brief

To obtain the correct product and the right contractor to provide a waterproof solution for the next twenty five years. SMD services included preparing all the contract documents, and the usual CA and QS duties. The works consisted of a new double skinned metal clad solution, which allowed for the installation to be increased beyond building regulations, to reduce the amount of condensation. The Tata steel plastisol cladding panels, eaves, flashings and guttering offers a 25 year guarantee for this marine environments.

Project Solution / Outcome

This was a challenging project, carrying out the works at a height of 29m within a live environment. Netting was installed within the DryStack to not only offer a fall arrest system, but also to catch any debris that fell during the works. Materials were craned on and off the roof with four separate lifts during the projects. The lifts had to be carefully planned around the weather, to minimise any downtime of the fixers on site. The project was finished on time and on budget, even overcoming some additonal rust treatment which was discovered during the works.
