At SDG our knowledge of the impact of the correct acoustics in different environments grows it is no surprise that the education sector is one area where you can’t afford to be complacent.
Through the use of the BT turnbuckle on these LIDL store projects it has been possible to reduce the temporary bracing, increase safety and shorten the assembly time for the precast wall elements , it ticks all our the boxes. We are excited to implement it in our future projects.
SDG have always gone above and beyond for us. With SDG’s technical support our team have the ability to use the most effective and innovative solutions to improve quality, save time and perform more effectively.
I spoke to Ciaran Donnelly and after a few subsequent drawings emailed back and forth we agreed on the detail. SDG had the assembly on site within 3 days and saved us a lot of time on site with cutting and welding. We were able to lower the assembly into place in one piece with no concerns. I would most definitely engage in this service again.
