In todays Herald, Cairns said the club believes their facilities could quickly be upgraded to accommodate the Warriors, providing them with an all-purpose home ground.
"It is feasible, but the SRU would have to put up two temporary stands either side of our main stand and floodlights, while drainage would also have to be improved," he noted in The Herald.
"We are keen to be involved with them but there's a lot of discussion and debate to take place because we also have to make sure that it is of benefit to our club as well."
A Warriors spokesperson said last weekend that they are currently weighing up a range of options and expect to say within the week which is its preferred option. Partick Thistle's Firhill is popular with players, geared as it is to professional sport, while the location of Hillhead/Jordanhill's Hughenden means it remains the supporters' favourite.
Like Burnbrae, substantial work would have to be done to turn Whitecraigs, currently the pro team's training base, into a suitable match facility but it is even further afield, on the South Side of the city.
The new Falkirk Stadium, boasting the best facilities of all, has also been suggested, but it is 30 miles from Glasgow so would be deeply unpopular with the core support.
Cairns was unwilling to make an estimate of the cost of the work required to get Burnbrae into a suitable condition but it is unlikely to come in at much less than a six-figure sum.
The link with West Of Scotland would be all the more attractive if the negotiations the club has long been involved in regarding the possible sale of Burnbrae with a move to an alternative site was to come off, providing them with the cash to create a purpose-built facility.
That is unlikely to be in place any sooner than the City of Glasgow's Scotstoun Stadium development, which is targeted for completion in 2008 and the Warriors' challenge is identifying accommodation for the immediate future.
