Contractor: Wicker Construction, Portsmouth
Project Completion: May 2015
Timbers bolted into load bearing steelwork across a full width dormer using Joyner Bolts.
All engineered bolted connections undertaken with M12x125 Joyner Bolts.
Dormer was clad with plasterboard for fire protection but required no countersinking before boarding due to flat head of Joyner Bolt fixing.
50 M10x115mm Joyner Bolts used.
Conclusion & Feedback
Contractor reported that the job would have been very difficult to complete without Joyner Bolt and was of the opinion that even if the cost was double it would be viewed as insignificant within the overall context of any high value project.
