Tender description

Dublin City Council proposes to establish a multi-party framework agreement for 1 year approximately to August 2021 for the supply of both high level and low level lane-separators. The lane-separators are to be used to provide protection for cyclists from side swiping by motor vehicles. They must consist of two principle components, a base unit that can be bolted to the road surface and a vertical wand. They will be installed along the boundary between cycle lanes and the general carriageway. A multi-party framework agreement for 1 year approximately to August 2021 for the supply of High Level Lane-Separators. Lot 1: High Level Lane Separators: The base unit must be between 150 mm and 200 mm wide, 100 mm — 150 mm high and a length of between 700 mm and 1 000 mm long. The base must have rounded/gently sloping profiles on all sides. The vertical wand must stand between 800 mm and 10 000 mm above the carriageway when inserted into the base. It must be designed so that it is fixed solidly into the base. The base must be supplied with fixing holes to allow it to be fixed securely to the carriageway. The vertical wand must be an impact resistant, reboundable post approximately 70 mm to 90 mm in diameter (or equivalent). The wand must have a proven and tested durability and must be capable of withstanding multiple hits from vehicles before returning to its vertical position. A multi-party framework agreement for 1 year approximately to August 2021 for the supply of low level lane-separators. Lot 2: Low Level Lane Separators: The base unit must be between 160 mm and 200 mm wide, 100 mm — 120 mm high and a length of between 600 mm and 700 mm long. The base must have rounded/gently sloping profiles on all sides. The vertical wand must stand approximately 400 mm above the carriageway when inserted into the base. It must be designed so that it can be fixed solidly into the base once the base has been bolted securely to the carriageway. The vertical wand must be an impact resistant rubber tube approximately 60 mm to 80 mm in diameter (or equivalent) that must be capable of withstanding vehicular traffic driving over it. The wand must bounce back to its original vertical position once the vehicle has passed over it. The wand must have a proven and tested durability and must be capable of withstanding multiple hits from vehicles before returning to its vertical position. It must have passed a durability test of 50 hits at 30kph with a 800 kg truck (or similar durability test). It must be possible to replace the vertical wand without removing the base unit from the carriageway.
