At Logan Construction, we are very experienced at working on Grade I and II listed refurbishment projects in sectors such as healthcare and education.
Projects we have successfully undertaken on Grade I and II listed often include external facade retentions and renovations, whilst preserving internal features and yet providing high quality working environments that are function and suitable to today’s modern requirements.
Appreciation of the building
Our specialist teams appreciate the sensitivities of working within Grade I and II listed projects. We work hand-in-hand with our client’s, local authorities, English Heritage and other stakeholders to ensure a smooth refurbishment process, and address any concerns during the construction and refurbishment programme as they arise.
When working within listed buildings, we utilise the expertise of specialist consultants and we select our experienced supply chain specifically upon their experience and knowledge of working with listed projects.
We have completed numerous projects that have required BREEAM ratings on listed buildings.
Working within a listed building is always challenging, but also very rewarding.
So what’s the secret to a successful refurbishment within a listed building?
Understand the brief before you start – especially when being asked to value engineer the price down and ensure the risks are clear to those estimating the job. If the tender is unclear, it means the design team may not know, so it will need further investigation – be it during the tender or during the construction phase, either way it is a cost and time issue for all.
Access – careful thought needs to go in to the planning of access routes and materials handling. While size will be a significant factor, weight is also critical. You also need to understand the building you are accessing. Do you know if the floors are solid or are there any unknown voids e.g. graves in church floors? Can they be identified by ground penetrating radar where a CAT scan is insufficient? Will floor finishes take the loads imposed? These can be overcome by building “runways” to span voids/ spread loads or by changing the design to use smaller components.
Structural alterations – monitoring of the building while works are being undertaken – could be simple “tell-tales” through to electronic measuring devices and motion/vibration detectors. It needs everyone to firstly understand what they are trying to measure and then what the appropriate threshold levels are before the alarm is raised. For example, vibration affecting showcase exhibits/causing cracking to plaster.
Programming and sequencing – again it requires an understanding of the risks involved. This needless to say, covers all facets of the works but also needs the people directly involved to appreciate that once a sequence has been agreed it must be adhered to, or if has to be changed, that everyone in the decision process must be involved. What may seem a simple item may have significant impact on others.
Above all the trades need to be “sympathetic” to their environment/surroundings.
