As early as possible to ensure that we can assist with the design requirements because we can often see potential issues or savings before the project has began its core build

We can & are often called upon in these scenarios, often the Smoke Clearance has been overlooked before construction starts or there has been a change of use or building control requires additional protection, we can often see solutions to problems & advise accordingly

No – in fact we prefer to work with your approved installers as it often saves you money. As long they can follow installation drawings/specification & are available before commissioning/final fix then we have no issues at all. 

We have found that unfortunately there is sometimes a mis-read of the regulations surrounding Mechanical & Natural Smoke Systems & the building size does not always require/warrant one, providing we are contacted at design/preinstall we can normally provide an alternative solution that will be compliant
