Profile

Sergio has over ten years of solid experience working as a bridge and structural designer. As a bridge designer, Sergio has developed advanced structural analysis models and con-struction analysis of steel and concrete vehicular and pedestrian bridges. He has a large experience on finite element analysis including static and dynamic (both response spec-trum and time-history).

As a Senior Project Engineer, Sergio has worked on various medium and long-span bridges, including concrete, steel and GFRP structures, as well as pile foundations, substructures and retaining walls. His experience includes design of heavy civil works and various build-ings.

Sergio has been participated in various Design- and-Build and PPP projects in North-America including the preparation of the tender bid for the cable-stayed bridge of Goeth-als- with a main span of 265 m - (project leaded by Dragados), Fort York project in Toronto consisting in two signature Stainless Steel pedestrian and cycle bridges, and currently is participating to the design of deck and hangers installation of the signature arch Walterd-ale Bridge in Edmonton, AB with the main span of 206m.

Bridges in Camp Lejeune, North Carolina

Goethals bridge, New York

SR 826 /I-75 Express Lanes Project. Miami Dade FL.

Sergio has provided technical assistance in the preparation of bid proposals for Design- Build and PPP bridge projects in Canada and USA for major construction firms. The ser-vices have included in most of the cases the preparation of design concepts and study of alternatives (including preliminary structural analysis), evaluation of construction meth-ods and quantities estimation to provide a cost-eff ective solution and/or to guide and supervise the work the lead main designer. Sergio has been directly involved as structural engineer and coordinating Pedelta’s project teams. His experience includes:

SR 826 /I-75 Express Lanes Project, Miami Dade County, FL (DB)Senior Structural Engineer, 2013Preparation of the Design and Build tender documents of the bridges and retaining walls for the SR 826/I75 Express Lanes Project. Miami, FL. The project includes the addition of 13 miles of express lanes along the Palmetto Expressway (SR 836) and I-75 (SR-93). Our scope of services included the preliminary design and development of 30% Design Plans based on a preliminary structural analysis and design using FDOT standards, quantities estimate and other technical documents for tendering the contract.

Goethals bridge, NY-NJ Port Authority (PPP)Project Manager, 2012 – 2013

Pedelta was retained as the Design Coordinator for one of the Construction JV leaded by Dragados and to complete an independent structural assessment for the Main Bridge proposal of the Goethals Bridge Replacement Project. The scope of services included a study of alternatives for both the main span bridge and the approaches. The proposed Main Bridge is a cable stayed structure with a main span of 265 m (870 ft) and inclined 111 ft (34 m) high concrete towers.

Constructability analysis of Nipigon cable-stayed bridge, OntarioSenior Structural Engineer, 2013The engineering services provided included the constructability analysis of the Nipigon Cable-Stayed Bridge for the preparation of a tender proposal. The bridge consists of a four-lane cable-supported steel-concrete deck with 2-spans of 139+113 m. The super-structure consists of two connected fl exible decks that accommodate two-lanes each in each direction. The 70 m tall tower has three pylons and the stays are placed in a sem harp arrangement. The study includes the assessment of various erection alternatives.

Erection procedures for deck and hanger installation of the Walterdale Arch bridge, Edmonton, ALSenior Structural Engineer,04.2015 - ongoing

The Walterdale bridge replacement over the North Saskatchewan River in Edmonton is a signature structure with a 206 m long main span. The bridge features two 43 m high steel arches tilted inwards. Pedelta has been assigned to develop the complete erection procedures, including drawings and structural calculations for the traffic and pedestrian decks and hanger installation.

Construction engineering of Bridges in Camp Lejeune Marine Corps Base, NCSenior Structural Engineer, 2013

The construction engineering services provided included erection systems, Accelerated Bridge Construction (ABC) procedures and crane loading analysis for Wallace Creek Bridge and Bearhead Creek Bridge in Camp Lejeune Marine Corps Base, North Carolina. The 950 ft long bridges have been studied including the assessment of Top-Down alternate construction methods to provide economic and time savings minimizing environmental impact on the wetlands.

Mary Island Railway project, Baffinland (DB)Senior Structural Engineer, 2011 - 2012

Review and submission of technical proposals to minimize quantities and cost on the de-sign of the bridges included in the Mary River Project (railway and associated facilities) for Baffinland Iron Mines Corporation.

Viaduct over Ter River in Girona, Spain

Hisgaura Bridge, Colombia

Hisgaura cable-stayed road bridge, ColombiaSenior Structural Engineer, 2013 - under constructionStructural Lead (concept and detailed design) of a 640 m long cable-stayed bridge over the Hisgaura Gorge in the State of Santander. The bridge has a main span of 330 m and two back spans of 125 m each. The deck, 13.8 m wide, accommodates 2 traffic lanes and is suspended on two lateral cable planes. The deck consists of two longitudinal stressed concrete girders -2m in depth- which are supported by the stays each 10m.

Viaduct over Ter River in Girona, SpainSenior Structural Engineer, 2011 – 2015

Feasibility study, conceptual and detailed designs, and technical assistance during con-struction over the Ter River. The nine-span bridge consists of a continuous deck with an overall length of 485 m. The main span lenght is 120 m and its deck is supported by a curved tied steel member between two pylons. This central curved tied memberabove the deck level splits into two branches over the side spans and creates two doorways.

Three Cable-Stayed Bridges in Oyala, Eq. GuineaSenior Bridge Designer, 2009 - 2014

Three cable-stayed bridges crossing the Wele River in Oyala. These signature bridges will become a new emblematic entrance to the new city developed by the Government of Guinea Equatorial. The bridges have an overall length of 135 m (412 ft), with a main span of 80 m (244 ft). The deck, 22.6 m (69 ft) wide, accommodates six road traffic lanes, a central median, and two pedestrian walkways. The deck is a composite steel-concrete structure supported by two lateral cable planes. Construction of the central span is made using a balanced cantilever method to reduce construction impact on the River.

Bridges of Mollet Railway Interchange, SpainStructural Engineer, 2008 - 2010

The Mollet Interchange includes four railway viaducts with an overall lenght of 1.33 km. The first three structures consist of a reinforced concrete deck supported by two precast concrete U-girders. The forth structure is a steel bridge with and X-shaped plan view and is designed with double composite action. Sergio was responsible for the design of the bridge substructure, the structural analyisis including track-structure interaction, vertical and horizontal forces distribution and seismic analyisis.

Footbridge Over Segre River in Lleida, SpainSenior Bridge Design Engineer, 2008 – 2010A four spans frame footbridge with 163 m length. The composite FRP-steel-concrete deck was supported by three slender piers of reinforced concrete. The footbridge features LED lighting system under translucent FRP floor panels.

Vall d’en Bas Road Viaduct in Olot, SpainSenior Structural Engineer, 2007 – 2008Conceptual and detailed design of a steel Viaduct. This bridge was required to be as trans-parent as possible, with moderate long spans, a sober structure and a sustainable and environment-friendly type of construction. The decision towards a composite steel-con-crete solution was compulsory. The structure is formed by 9 spans up to 80 m long, with an overall length of 564 m.

High-speed Railway Bridges, SpainStructural Engineer, 2003-2007

Design of 13 bridges for the new HSR link Barcelona-French Border. The main bridge is the first steel-concrete composite bridge in the high-speed railway line Madrid-Barce-lona-French border with and overall length of 524.9 m and a width of 15.5 m, which was built using the launching method. The first part of the bridge is a composite steel-concrete structure crossing the highway. The second part is a continuous pre-stressed concrete bridge.
