Location Laktaši, BiH
Sector Infrastructure / bridge construction
Scope Construction of viaduct
The project is executed by DINARIK d.o.o.
It is shown here as our personal reference.
The viaduct is comprised of two individual structures (one per direction), each having two traffic lanes and shoulder road, each structure being subdivided into two expansion segments. Total length of viaduct is 500m (25+3×50+25+25+3×50+25). The superstructure of the viaduct is designed as a post-tensioned continuous ribbed slab (Homberg section), reinforced with transverse beams at the locations of the piers. Piers are formed out of two round columns, 120cm in diameter, and spaced at 6m. Foundations are designed as pile foundations (R=150cm, L=15-24m), with group of three piles at each pier location.
OUR ROLE IN THE PROJECT:
* CONSTRUCTION MANAGEMENT
* DESIGN OF SHORING AND FORMWORK
* RC DETAILING (PARTIALLY)
* 3D MODEL WITH EXACT COORDINATES FOR SURVEYING STAKING OUT
