Projektowanie i budowanie przy użyciu wirtualnych modeli (BIM)
In 2011 Skanska rebuilt the bridge in Rajskie, small town at the south of Poland. Bridge is located along the provincial road no 894 Hoczew - Czarna running around Solinskie Lake - so called Bieszczady’s small loop.
Bridge built in 1966-1967 was in a very bad technical condition (only one renovation was carried out in 1985 and focused on sidewalks). Poor condition of the bridge caused traffic congestion for several months. In 2010 one side of the bridge was excluded from the operation and some restrictions were made: capacity of 10 tons and speed limited to 30km per hour.
Unfortunately this resulted in further degradation All traffic focused on one road had its results in further bridge degradation. Temporary repairs could not guarantee the safety of road users. There was no certainty that bridge will be passable in the next tourist season.
Investor – Podkarpacki Zarząd Dróg Wojewódzkich w Rzeszowie has called for tender on reconstruction the bridge. The bridge was to be excluded from the traffic for the whole duration of works. All traffic was directed to diversions. It helped us to execute bridge works and allowed to shorten the duration of the investment. Two weeks before contract delivery date bridge was opened and put into use.
Benefits for the community
Thanks to the investment Bieszczdy’s bypass has gained the renewed and safe three-spans crossing of the San river. The capacity increased of 50 tons, what classified the object in the highest capacity class A by PN-85/S-10030. The project has improved safety and comfort of road users.
Segment rynku: Bridges
Within the investment Skanska rebuilt the bridge together with its access roads. Reconstruction consisted of total replacement of existing bearing structure with new construction based on existing supports, suitably converted and refurbished. We have completed a demolition works leaving the bridge abutments and piers. Partially demolished abutments have been strengthen and concreted. Supports surfaces were renovated by using PCC mortar.
Other elements of the bridge: bearings, construction, equipment were newly installed. We executed bridge caps, bridge deck with the bituminous pavement, sidewalks surface. On both sides we built pavements and strengthened and renewed access roads. Bridge has zinc-plated railings with spacing of 1 m and reflecting elements.
It’s location and total length remained the same, width increased from 8,5 m before the reconstruction to 10,5 m after, due to road widening and installation of handrails on the bridge.
