The new interchange offers increased capacity and safety and helps cut congestion

The Section 5 Palmetto SR826/836 Interchange project in Florida has won the 2016 FICE Engineering Excellence Grand Award in the Structures category.

FINLEY Engineering was the engineer of record for the four segmental bridges, Number 9, 11, 15 and 19, and provided construction engineering expertise. The segmental bridges were precast, balanced cantilever and erected with a 140.2m launching gantry. The bridge lengths varied from 335.3m to 746.76m in length and are 14.35m-wide, with a maximum span length of 81m. The curved segmental bridge ramps are the third level of the interchange with radii down to 180m and have a maximum superstructure deck height of 29m. above the proposed ground. All of the bridges are supported on 610mm pile foundations and reinforced concrete piers and caps. The project was carried out for 2697 Florida Department of Transportation, the contractor was the Community, Condotte, De Moya Joint Venture and the prime design consultant was BCC Engineering.

The bridge design offered unique challenges integrating underlying roadways, canals and MOT requirements into the layout of these segmental bridge ramps. This project was constructed in the Miami International Airport flight path and had FAA Requirements. The high level segmental flyovers are built over multiple roads that carry 430,000 vehicles/day and are the tightest elevation curves erected in the United States. The all overhead erection eliminated the need for falsework and cranes and eliminated five MOT phases that would have impacted traffic, thereby providing a safer work environment. FINLEY integrated the design into the construction while satisfying the strong aesthetic requirements. The design reduced maintenance and construction costs with the use of external tendons, Diabolos and deviators. The use of polystyrene in the hollow pier columns, except at the base of the caps, eliminated the need for interior formwork and reduced the overall mass of the structure and concrete required.

    Located in Zhejiang Province of China, Jiashao Bridge spans the Qiantang River and connects the cities of Jiaxing and Shaoxing. The total length of the bridge project is 10.14km and carries an eight-lane expressway The Qiantang River suffers from a high flow rate of up to 7.5m/s. As the tidal range is around 7-9m, the water depth is less than 2m in time of low level tide, so ships can only move at high tide and large scale ship-lifting equipment cannot be used downstream of Jiashao Bridge. However, to

    A team of Greek and German PERI engineers have developed a comprehensive formwork and scaffolding solution for the T4 bridge on the A7 motorway in Greece. The 160km long A7 connects Kalamata in the south to Corinth in the northwest of the Peloponnese peninsula. On one stretch of the motorway a 390m long arched bridge – known as T4 – is being used to close the gap between Paradisia and Tsakona. Set for completion in early 2014, two-thirds of the 22m wide bridge superstructure will be suspended on a steel arc
