MR. A. FREDERIKSEN BAEKSTED HAS AN ALL ROUND EXPERIENCE IN BRIDGE ENGINEERING COVERING DIFFERENT SIZES AND TYPES OF BRIDGE STRUCTURES AND ALL OF THE DESIGN STAGES WITHIN BRIDGE DESIGN. PROJECT MANAGEMENT OF BRIDGE PROJECTS AND INTEGRATED ROAD /RAIL AND BRIDGE DESIGN INCLUDING ALSO OTHER VALUE ENGINEERING ASPECTS. LEADERSHIP OF TEAMS CAPTURING INTEGRATION OF REQUIREMENTS IN TENDER DOCUMENTS, DESIGN INTENTIONS AND ADAPTATION OF CONTRACTOR DRIVEN REQUESTS AND PREFERRED METHODS AND EQUIPMENT ARE ONE OF HIS FOCAL POINTS.

PREDICTED TOPIC OF KEY NOTE: PUENTE NIGALE

CONSTRUCTION OF THE SECOND FIXED LINK ACROSS THE MARACAIBO LAKE IN VENEZUELA – THE PUENTE NIGALE – STARTED IN 2012. THE TOTAL LENGTH IS AROUND 11 KM FROM COAST TO COAST AND CONSISTS OF APPROXIMATELY 1.3 KM SHORT SPAN BRIDGES AT THE COASTLINES, 4.5 KM LOW LEVEL BRIDGES, 4.8 KM ELEVATED BRIDGES AND TWO PARALLEL 910 M CABLE STAYED BRIDGES WITH 430 M MAIN SPAN ACROSS THE NAVIGATION CHANNEL IN PRECAST SEGMENTAL CONSTRUCTION, WHICH WILL BE WORLD RECORD FOR A ONE LEVEL CABLE STAYED BRIDGE CARRYING RAILWAY TRAFFIC. THE DESIGN ADOPTED ON THE NEW LINK ACROSS LAKE MARACAIBO IS DIFFERENT THAN TRADITIONAL FIXED LINKS CARRYING BOTH ROADWAY AND RAILWAY TRAFFIC. DUE TO THE TIME SCHEDULE AND PHASING OF THE PROJECT AS WELL AS IMPORTANT ASPECTS OF CONSTRUCTION, IT IS DEEMED ADVANTAGEOUS TO DESIGN AND CONSTRUCT TWO PARALLEL BRIDGES WITH INDEPENDENT SUPERSTRUCTURES FOR ROAD AND RAIL, RESPECTIVELY, BUT WITH COMMON FOUNDATION. THIS NATURALLY LEADS TO SUPERSTRUCTURES OF THE ONE-LEVEL TYPE AND IN THIS PARTICULAR CASE CONCRETE IS THE PREFERRED MATERIAL BECAUSE OF SUPPLY OF MATERIALS AND TRADITION OF MAINTENANCE.
THE KEYNOTE LECTURE WILL PRESENT DESIGN DEVELOPMENT OF THIS PARTICULAR PROJECT, FOLLOWED BY A COMPARISON WITH OTHER LARGE SCALE FIXED LINKS WITH A VIEW TO EXPLORING WHETHER A GENERAL TREND CAN BE IDENTIFIED.
