Project Organisation

The work is part of an EWI & roofing scheme. Work was undertaken to 26 tenanted & leaseholder blocks of flats and completed in five months. Before commencement, Jefferies worked closely with the Tai Calon CoW to produce the best programme to suit all parties. The programme and risk register were completed in collaboration with Tai Calon to minimise disruption and to ensure health and safety to all tenants and the public were protected. Any particular areas of risks were highlighted to Jefferies and our site team ensured these were monitored more closely to prevent accidents/issues arising.


The team worked in closely with Tai Calon CoW, Project Manager and the tenants to ensure the programme was fully understood and were flexible in assisting to solving problems proactively. Customer satisfaction surveys were given to each tenant in order to ensure we constantly developed and improved our service resulting in exceptionally high levels of tenant satisfaction.
