If so, you’ll only requireasingleuse of scaffolding and all the disruption can be contained in a single period of externalmaintenance. This is theideal scenario,and is worthconsidering if youaremaking adecisiononeconomic rather than safety grounds. If thedecisionisout of your controland the

Many of the roofs had been suffering fromleaks as the single ply systemhad been punctured andwas poorly detailed. Earl Kendrick has been involved in implementingmajor roof refurbishment works.Wherein good condition, the single plymembrane has been left in place and the roofs have been coated with a new Liquid Plasticsrepair system, providing a guarantee of 25 years. Part of the decision to use the liquid applied refurbishment systemwas the presence of communal plantandmachineryon someof the roof areas,which could be left in placeand thenewliquid system worked around the equipment.

beinginstalled) nPreparing the specification of works and
managing the tender process nAssessing tenders nAdvising on theappropriatechoiceofformal
Building Contract forthe works nManaging the works on site and
