Mitie, Honeywell Controls, Johnson Controls and Building & Property are the latest companies to form alliances in a bid to win a slice of BT’s yearly £160m maintenance spend.

It is understood that contractor Mitie has teamed up with the Dalkia/Bovis partnership and that building management specialist Honeywell has joined the Citex/Mace team.

Another building management specialist, Johnson Controls, is understood to have linked up with QS MDA. Facilities manager Building & Property is working with Kier.

Regus, a developer that supplies serviced offices, is understood to have dropped out of the race to win a slice of Project Jaguar.

In August, BT revealed a list of 16 preferred bidders. By September, Bovis and Dalkia had joined forces. WS Atkins, contractor Mansell and services specialist Drake & Scull have also formed an alliance, and contractor HBG has teamed up with services contractor NG Bailey.

BT says the work, which may include capital projects as well as the maintenance, will be awarded to between two and four bidders.

The original long list of 16 has now been reduced to 11. These are: Amec, Bovis/Dalkia/Mitie, Carillion, Citex/Mace/ Honeywell Controls, HBG/NG Bailey, Mowlem, Johnson Controls/MDA, Kier/Building & Property, Mansell/WS Atkins/Drake & Scull, Morgan Sindall, Servus and Taylor Woodrow.
