Two contracts, covering the East and West of the borough, would cover cyclical planned maintenance of street trees as well as responsive and emergency works to trees in parks, highways, woodlands, housing sites, allotments and other sites.
The third contract is to provide planting and maintenance of young trees. Each contract is worth at least £200,000 per annum, and would last for four years with the potential to extend for a further two years.
Tenders are due on 18 September. Shortlisted contractors will be assessed on the quality of their work before the final decision is made. Winning contractors may be required to form partnerships with local suppliers.
Barnet's trees and woodlands manager Andy Tipping has also come up with a graduated pricing structure he believes will be fairer to both the council and the contractors. Instead of the traditional bandings which see large jumps in price when a tree reaches a certain diameter, each tree in Barnet will have its own price based on its exact diameter.
A supplier event will be held at 10.30am on 18 August at Saracen's Rugby ground, Allianz Park, North West London. Suppliers must register for the event by email to firstname.lastname@example.org.
