University of Oxford’s Weatherall Institute Of Molecular Medicine Building At The John Radcliffe Hospital – DDA Accessible Swing Door Conversion
This project was following a DDA access audit for University of Oxford to allow easier access for all using the Weatherall Institute of Molecular Medicine Building within the John Radcliffe Hospital in Oxford.
A survey was carried out on each door to ascertain the precise requirements and operational needs for the users. At BH Doors want to ensure that your installation, fits the requirements, provides a solution, works operationally and above all safely. Our solution was to install Record DFA127 swing operators to the existing timber and steel door sets.
The timber doors are security doors with integral locking, we had to interface with the access control system so that when the users present their card the door would automatically unlock, open and after a time delay, close and relock. The steel doorset are situated within a busy corridor and the solution was to fully automate the doors so that when a person walks towards the door it automatically opened by means of a Radar movement sensor.
Where false activation from persons passing the corridor, we installed battery powered touchless buttons which perform the same function as the access control in operation. The reason for wireless technology is that these can be installed anywhere within the proximity of the door without the need to provide containment for cabling, thus saving time and money.
Automatic doors have a number of risks and in particular with a swing door, Impact and Crushing where the door could open or close upon a person. To eliminate this risk, we installed an on-door safety sensors from BEA called Flatscans to both sides of the door leaf.
During commissioning and a service, we test that these sensors are detecting correctly using a BS EN16005 test box which replicates a person stood within the sweep area of the door. The basic test is that the door should stop before touching the box during the operation of the door.
On completion we tested the complete system and handed over O&M manuals, commissioning documentation and demonstrated the use to the Building Manager and Estates department.
