Reading Station Area Redevelopment
Cleshar was awarded a civils works section of the Reading Station Area Re-Development (RSAR) contract which was to be completed within a 35hr window during a 52hr possession.
Scope of works
Removal of the top ballast for the length of the track removal
Removal of the existing subway deck constructed from steel troughing and the removal of the top sections of the brick abutments.
Installation of new pre-cast cill sections on the remaining abutments together with elastomeric bearings on which the new pre-cast deck section was installed.
Contract Start and Completion
Capital Works / Civils
Owing to the weight of the deck (41t) and the reach necessary (38m), a 1,000t crane (LTM 1800 supplied by Ainscough) was employed to lift the deck into position.
The Pandrol track fastenings were attached to the bridge prior to the possession to save time during the installation phase.
In removing the existing deck, a free edge was created to the existing deck which needed to be supported along its length with steelwork which was welded to the existing troughing.
Benfits / Project Outcome
The bridge abutments were waterproofed and backfilled, and the area was handed back on time.
