The museum’s steel structure has rounded ends designed to resemble a ship’s hull, and more specifically, Mary Rose’s hull while the roof was installed on prefabricated units and supported by 32m long rafters. It has two conventionally piled pavilions on either side. The lead structural designer, Warnings paid special attention to the frame to ensure it effectively fit Mary Rose. The biggest challenge in the frame’s design was in the erection of the main beams over Mary Rose’s ship. However, this was overcome by splitting the beams into 3 sections with 2 fixed to side columns initially, while the central section was the last to be positioned. The lifting of the central section was aided by a 20% oversized mobile crane and a sling supporting the beam at each of the ends. Additionally, cherry pickers were used in bolting the central section to the main section with the cherry picker baskets encapsulated with netting and tools tethered using lanyards to lower falling object’s risks. Metsec steel framing was attached to the frame as well as black stained timber reminiscent of the ship’s hull.&nbsp.
