It is always a great pleasure to secure repeat business with architects and contractors. This project with Morey Smith is one of several completed with this practice. Here, OAG developed a bespoke glazing system solution using factory silicone bonded carrier frames onto high performance double glazed units.
The glazing was supported from mild steel RHS profiles, which were limited to a narrow profile for maximum daylight. In conjunction with Adams Kara Taylor, commisioned by OAG to undertake the structural design for this particular project, the vertical wall required an innovative bracing solution to control deflections within the tight limits required for the glazed element. This solution allowed OAG to produce a frameless eaves connection, which draws particular emphasis to the natural light flooding into the new atrium.
Working on a site completely enclosed by multi-storey buildings is always a challenge. For this project, we knew that to be cost effective, craneage must be kept to a minimum. For this reason, we designed and installed a temporary running gantry, three floors above the working area, fixed to existing mounting points for cleaning cradle access.
From this gantry, all roof glazing was carried out, and due to the location, could continue even at times when high winds would preclude the use of a conventional crane. This limited mobile crane use to just four weekend visits, allowing OAG to achieve a weathertight construction on program, without causing disruption to the surrounding businesses.
Within the atrium, three projecting pod windows were constructed, walk-on glass floor elements and a fully bonded construction to all projecting glass panes. This was achieved by including temporary structural supports as part of the installation, which allowed the large window front glass to be securely held in place during the bonding and curing process.
