Sensor operation is more ideal except where there is the potential for a lot of unscheduled operation by people passing the sensor on either side who don't intend using the door - this obviously puts additional wear on the unit but depending on the time of year , can also affect the interior temperature of the building especially in the winter if they are constantly operating.
I did see some doors fitted somewhere that were more assisted opening ie you still had to push or pull the door but were assisted by the door once it got beyond a certain point (usually just beyond ajar). This prevented unnecessary operation but ensured 'most' people could use it without a problem and they seemed robust.

In my experience the drawback with the bush button is two fold
Weather conditions and degradation of the internal electrics leads to system failure And the individuals need a reasonably high level of physical strength, dexterity and also the limbs to operate such devices.
As such I would suggest a PIR movement sensor rather than bush button

Hi Alyson,
I agree with Alan with the approximate cost for this type of work
Just a word of advice on push button operation. We have this type of control on a number of our buildings. We have noticed that some users will not use them as they either do not notice them or think they are not for there use. This leads to them attempting to open the door manually which can be heavy before the automatic openers activate.
In some instances we have replace the push buttons for sensor.

Hi Alyson
I have commissioned a few of these and they tend to cost around £4000 at the moment for the pair of doors including side safety barriers etc.

Subject: Cost of automating existing swing doors
Hi. We have clients who are looking to move to new premises, which has existing manually operated double swing doors, which they want to automate with a push button on a pedestal. Does anyone have any experience of this sort of work who could give me approximate costs for this? The costs don't have to be exact, just approximate.
Thanks
