The deal comes ahead of the opening of the new Waitrose Helensburgh, which is on target to open its doors this month, following a successful construction and fit out by Barr.
The Chester store will be Barr Construction’s fifth Waitrose project in the UK, following projects in Helensburgh, Stirling, Walton-Le-Dale and Newton Mearns.
It secured the job, where work is due to start in the Spring, against Buckingham Group, Bowmer and Kirkland, McLaren and R G Carter.
Derek Simpson, operations manager at Barr, is looking forward to continuing the partnership with the retailer.
He said: “The Chester contract win is a testament to our track record of delivering stores for the major retail chains over the past 20 years.
“As the first Waitrose we have handled all construction and fit out activity for, the Helensburgh store has been a flagship project for Barr.
“On the back of the Helensburgh opening, it is especially pleasing to announce our second construction and fit out project with the retailer.”
