Surface work for highways

Tender description

A multi lot specialist supplier framework to deliver focussed renewals, to maximise the life of the existing concrete pavement. Scheduled joint repair works to concrete road surfaces. The work includes: — the replacement of old joint material between slabs with new jointing, — it also covers small patches and thin bond repair to cover faults, such as small to medium punch outs, spalled edges, failed patches less than ½ a slab, linear inline repairs up to 600 mm wide, by 150 mm deep, repair/replacement of ironwork and surrounds, previously repaired stud holes, kerb edging, — repairs will use both flexible and rigid repair materials. The aim with the rigid repairs will be to use concrete to concrete repairs where possible, — high performance joints between different materials, such as transitions and bridge decks, — re-installation of loops or magnetometers, — introduction and/or widening of construction joints. The Lifecycle Extension Works contractors will be expected to provide: • construction of chosen intervention; • principal contractor duties; • traffic management; • welfare facilities; • early contractor involvement into design phase; • small works for localised planned repair. Provides contingency for other lots should the suppliers in those Lots be unable to deliver the works. Scheduled bay replacement and slab levelling works on concrete roads. The work includes: — full slab removal and replacement with early strength rapid set concrete materials, — ½ bay or greater full depth replacement, — this allows for pre-formed and precast slabs to be used for rapid repaid, — replacement of dowels between joints, — removal of depressions or heaves, — removal of previous significant asphalt repairs for replacement of concrete slabs, — re-installation of loops or magnetometers, — repair to stabilise ground conditions found under the base, — repairs to transitions (concrete), — introduction of additional reinforcement beneath, in slab. Slab levelling between joints use vacuum grouting, grout injection or resin injection. — stabilisation of the slab to raise it to improve longitudinal ride profile, — stabilise transitions between different materials, — stabilisation of areas adjacent to the mainline, such as laybys, entry and exit slips, embankments associated with the edge of the road. The Lifecycle Extension Works contractors will be expected to provide: • construction of chosen intervention; • principal contractor duties; • traffic management; • welfare facilities; • early contractor involvement into design phase; • small works for localised planned repair. Provides contingency for other lots should the suppliers in those Lots be unable to deliver the works. Scheduled surface treatment works on concrete roads. The work includes: — white topping, — thin surface course over asphalt, — deeper overlays in asphalt above 50 mm to a depth of 250 mm, — surface re-texturing, — longitudinal grinding, — surface milling, — repairs to transitions (asphalt), — repair to high friction systems. The Lifecycle Extension Works contractors will be expected to provide: • construction of chosen intervention; • principal contractor duties; • traffic management; • welfare facilities; • early contractor involvement into design phase; • small works for localised planned repair. Provides contingency for other lots should the suppliers in those Lots be unable to deliver the works.
