The Challenge

Forth® has completed various projects at The Priory, including the replacement of boilers and associated works in their plantrooms to secure their heating and hot water needs. This particular challenge focuses on the installation of air conditioning on the first floor of Ticehurst Hospital.

Ticehurst Hospital is purpose built. The rooms are heated by radiators, which are safely contained in anti-ligature housings.

The pipework in this grade 2 listed building is original in places, making it extremely old and presenting a unique set of challenges. As the pipework was regularly failing, and the only way of getting cooler air into a room was via an open window, we decided that the best solution for this site would be to install Air Conditioning VRV into the bedrooms ensuring there was both heating and cooling and providing a greater degree of comfort for the residents.

The Solution

No strangers to dealing with the particular quirks of listed buildings, Forth® were required to co-ordinate several trades including builders, fire protection, air conditioning and electrical services as part of a complete turnkey service for the project. The complex designs, coupled with the sensitive nature of the works required that the project was carried out with the best interests of the patients in mind, mitigating risks to the patients, reflecting the latest studies on mental health and adjusting the build accordingly.

Given the nature of the listed building, careful consideration also had to be applied to how and where the services could be run. It was also necessary to install temporary condensers whilst the roof was made structurally sound. Our forward-thinking mindset was applied in consideration to the electrical shutdown of the building, with the installation of multiple breakers required to manage the long-term installation of numerous condensers, reducing the risk of potential shutdowns in future.

The COVID crisis meant that there was an increased use of the rooms by patients, necessitating an adjustment in the programme of works whilst ensuring patient sensitivity. Future proofing was a critical component of the initial design, as works will continue on the building for the next three to five years. Fortunately, future planning is something we pride ourselves on at Forth®, and the work was completed on time and within budget, with the client extremely pleased with the end result.
