Kier, Wates, Morgan Sindall, Willmott Dixon, BAM, and Graham won places for major projects.
In total, 27 firms secured spots on the framework including many SME firms on lots for small projects up to £750,000.
Some of the projects expected to be procured through the framework include Schools for the Future jobs, a proposed new leisure centre in Leighton Buzzard and various housing projects.
The new procurement framework comes into operation at the end of this month and will support the council’s Strategic Plan.
Councillor Eugene Ghent, executive member for Housing and Assets, said the framework would speed up the procurement process and offer better value for money as external frameworks were not required.
“Having our own procurement framework and choosing from a carefully selected group of firms has significant benefits. It will offer cost savings and speed up the procurement process meaning we can get schemes built quicker.
“Importantly, we will work closely with a smaller number of firms forging important relationships and this collaborative working will ensure we can deliver quality, value for money projects which support our ambitions for Central Bedfordshire and our residents.
“We look forward to working closely with our selected partners over the next four years as we build prosperity for our local communities.”
