St Croix River Bridge Design Cover Proposal for: S t . C r o i x C r o s s i n g P r o j e c t April 27, 2012 Final Bridge Design Prepared for: Create Minnesota Department of Transportation Preserve Activate Prepared by: 100 South Fifth Street Suite 1500 Minneapolis, Minnesota 55402 Technical Proposal Technical Technical Proposal St. Croix Crossing Project Final Bridge Design • Perform a review of the bridge deck drainage system along with the hydraulic analysis of the bridges and the entire construction project. Produce final design and details for a bridge drainage system balancing the visual elements of the box girder bridges with the external drainage pipes necessary to convey the drainage. • Deliver final construction plans by May 17, 2013 with a design that is developed to keep the construction cost within the overall project budget. With our previous experience on similar projects, URS is very aware of and confident we will overcome all technical challenges associated with this project. These challenges include: 1) the understanding of complex load paths and force flows within the extradosed structure; 2) the difficulties in constructing large foundations in water; 3) engineering challenges related to the bridge drainage system; and 4) developing a plan set and construction scheme that is economical and bidder-friendly. However, perhaps the most critical challenge to achieving a successful project will be to maintain both budget and schedule while developing all design deliverables. This logistical aspect of the project will require, first and foremost, the experienced and talented project manager we have chosen to guide this team, Steve Stroh, PE, PhD. For this important project URS is making its most experienced bridge manager available. Steve has the distinction of being the Engineer of Record (EOR) of the first Extradosed Prestressed Bridge in the U.S., the Pearl Harbor Memorial Bridge and is also one of URS’ most experienced project managers for complex bridge projects. Steve will be supported by an experienced, committed and dedicated staff that brings unequaled experience in extradosed prestress bridge design and the other necessary expertise to assure a successful outcome for this project. We are excited about this opportunity to help MnDOT with the final design of this very important bridge project. 3. Work Plan and Project Approach and Methodology PROJECT COORDINATION Contract Administration, Management, Schedule: Steve Stroh, PE, PhD, and Mark Maves, PE, will spearhead the efforts of the St. Croix River Crossing project management team. This team brings a balance of local experience with MnDOT and national experience on similar complex bridge projects. Their first task will be the Project Execution Plan, which will be delivered 10 days after the Notice to Proceed (NTP). The Project Execution Plan (PXP), shared with MnDOT, will include an estimated sheet count by number and title and the anticipated percentage complete for particular sheets for each submittal. Additionally they will have worked proactively prior to the NTP to mobilize within URS and our project team, ALL the resources necessary for this challenging project, such that, there is no lag time between the NTP and productive work being accomplished. With upwards of 300 bridge engineers nationwide, and with the support of our nine subconsultants, URS will bring to bear a large group of committed and talented individuals with a common purpose of providing a quality product to MnDOT for the St. Croix River Crossing Project. URS has experience with successfully completing similar large scale “mega project” assignments in a very limited time frame. Examples include, the Kap Shui Mun Bridge in Hong Kong (a major cable stayed bridge designed and constructed in 3 years), and the ROC 52 Design-Build project in Rochester ($240 million reconstruction project designed in one year). The Gantt chart shown on the following page illustrates our proposed design schedule to perform the tasks listed in the RFPs Scope of Work. Our URS experience with the preliminary, final and post design phases of the Pearl Harbor Memorial Bridge, the first extradosed bridge in the United States and of similar complexity to the St. Croix River Bridge Project, provides MnDOT with valuable insights and a minimal learning curve related to extradosed bridge design. The same team leaders for the successful Pearl Harbor Memorial Bridge project: Steve Stroh, Bob Anderson, Velvet Bridges, Richard Beaupre, Ed Bell, Scott Montgomery, and Daniel Mariscal also form the core team for the St. Croix River Crossing Project. Peer Review Coordination: Through our peer review of MnDOT’s Lafayette Segmental Box Girder Design, URS is very familiar with the interface intended between the bridge designer and the peer reviewer. We will accommodate open and effective communication with the peer reviewer and work with them to resolve all comments in a timely manner. We understand the value of this very important Page 2 URS Corporation April 27, 2012 ID Task Name Duration Start Finish June July August September October November December January February March April May June July August Septe E B M E B M E B M E B M E B M E B M E B M E B M E B M E B M E B M E B M E B M E B M E B M E B 1 Notice to Proceed (Assumed) 0 days Fri 6/1/12 Fri 6/1/12 6/1 2 Kick Off Meeting 0 days Thu 6/7/12 Thu 6/7/12 6/7 3 Design Review Meetings 260 days Sun 7/1/12 Mon 7/1/13 17 Design review teleconferences 240 days Sun 7/15/12 Sat 6/15/13 30 Project Managements Plan 10 days Fri 6/1/12 Thu 6/14/12 31 Document Security Plan 10 days Fri 6/1/12 Thu 6/14/12 32 Design and load rating criteria 10 days Fri 6/1/12 Thu 6/14/12 33 Receive peer review comments 0 days Thu 6/28/12 Thu 6/28/12 6/28 34 Final design and rating criteria 6 days Fri 6/29/12 Fri 7/6/12 35 Baseline P6 CPM 21 days Fri 6/1/12 Fri 6/29/12 36 Precast Vs.

  • Design and Construction of Extradosed Bridges in Cold Temperature and Seismic Zones
    Design and Construction of Extradosed Bridges in Cold Temperature and Seismic Zones Dr. Matthias Schueller, P.Eng. Vice President Parsons Structures Session 2020 TAC Conference & Exhibition Abstract Extradosed bridges are often described as a cross of a conventional prestressed concrete girder bridge and a traditional cable-stayed bridge because most extradosed bridges built combine a prestressed concrete superstructure with stay-cable technologies. However, this simple definition does not capture the various possible structural systems and different materials that can be found and used for extradosed bridges. Extradosed bridge technology is much more than a prestressed concrete girder with external tendons. The Deh Cho Bridge in the Northwest Territories and the Canal Lachine Bridge in Montréal are two Canadian extradosed bridges featuring steel superstructures with slender composite concrete decks using full-depth precast panels. Although both bridges are very different, they share one important design aspect which governed the design of their superstructures: Both bridges are located in regions with prolonged extreme cold winter periods. Temperatures below 0 °C and cold weather periods lasting up to five months can be a major hindrance when erecting long bridges with conventional concrete superstructures. On the contrary, steel superstructures are light and can be quickly erected, even at cold temperatures without heating and hording given that field welding is avoided. To avoid delays along the critical path in the erection of major superstructures in extreme cold temperature zones, designers should consider erection schemes which make best use of short warm weather periods and reduce negative impacts related to harsh weather conditions as best as possible.

INTRODUCTION During XIX century, one of the most relevant contributions to bridge engineering has been the introduction of prestressed technique, which is a solution to the need of controlling stress on elements in bridges. Initially this technique was employed by means of internal and external prestressed tendons, until 1925 when modern cable-stayed bridges appeared –the Tempul Aqueduct, which was developed and built by Eduardo Torroja (Torroja, 1927).

  • Extradosed/Cable-Stayed
    CHAPTER 6: ENGINEERING CONCEPTS Image 6.5: Extradosed/ Cable Stayed Image 6.6: Extradosed/ Cable Stayed Extradosed/Cable-Stayed Enlargement The extradosed/cable-stayed bridge uses a series of cable-supported spans to cross the river with equal span lengths of approximately 300 feet, as shown in Figure 6.7. The superstructure would be supported by cables above the deck anchored at one end to a central pylon and at the other end to the edge of the deck. The towers or pylons would extend 48 feet above the deck. The deck elements could consist of either steel or concrete edge girders or concrete box girders. With a span length of 300 feet, it is anticipated that variable depth (haunched) girder elements would be practical and would provide optimal aesthetics, as shown in Figures 6.8 and 6.9. Figure 6.9 presents a full build concept that is designed to accommodate the widest cross section in the study, Alternative 8. The towers would consist of concrete elements located on the outside of the deck at the ends of each span. A variety of options are available for the arrangement of the superstructure cables. One advantage of extradosed or cable-stayed construction is that it is possible to perform the construction in a top-down fashion using balanced-cantilever erection. In this scenario, few if any temporary supports would be required in the Potomac River during construction. However, balanced cantilever construction results in significant unbalanced loads on the piers and foundations during construction, potentially resulting in larger and more expensive foundations.

    TECHNOLOGY REPOrt published: 03 January 2017 doi: 10.3389/fbuil.2016.00037 Extradosed Bridges in poland—Design and Construction Jan Biliszczuk1,2*, Jerzy Onysyk1,2, Wojciech Barcik2, Robert Toczkiewicz2 and Artur Tukendorf 3 1 Wrocław University of Science and Technology, Wrocław, Poland, 2 Research & Design Office Mosty-Wrocław, Wrocław, Poland, 3 Budimex S.A., Warsaw, Poland The road and railway infrastructure in Poland has been intensively developed and modernized for the last years. Around 300 new bridges are built annually. Among the new structures, there is a group of modern extradosed bridges. This paper presents examples of short-, medium-, and long-span extradosed bridges designed and built in recent years in Poland. The following structures are described in details: (1) the first Polish extradosed bridge; (2) two-span landmark viaduct over motorway; (3) multi- span curved motorway bridge; (4) the longest Polish extradosed bridge; (5) tramway extradosed bridge; and (6) conceptual designs. The paper is concluded with geometrical parameters characterizing presented structures. The parameters are compared with values obtained for cable-stayed bridges and extradosed bridges built worldwide. Edited by: Keywords: extradosed bridge, prestressed concrete, design, construction technology, geometrical parameter Anastasios Sextos, University of Bristol, Greece INTRODUCTION Reviewed by: Luigi Di Sarno, The extradosed bridge is a relatively new type of structure that has been developed since the 1990s. University of Sannio, Italy Stergios Mitoulis, The first such structure was the Odawara Blueway bridge, which was designed and constructed in University of Surrey, UK Japan (Shirono et al., 1993). The extradosed bridge can be defined as the structure being between the girder bridge and the cable-stayed bridge (Mermigas, 2008; Collings and Gonzalez, 2013).

  • Extradosed Bridge Design One of a Kind on I-95 Project
    BY JAMES A. PLATOSH, P.E. CONTRIBUTING AUTHOR Extradosed bridge design one of a kind on I-95 project he replacement of the Pearl Harbor Memorial Bridge, which spans the Quinnipiac River in New Haven, Conn., will be the nation’s fi rst bridge to employ the technique of “extradosed” design—a relatively new concept that is a hybrid between a box girder Tand a conventional cable-stayed structure. The existing bridge is a girder and fl oorbeam design, in which steel beams support the concrete bridge deck. Known locally as the Q-Bridge (for Quinnipiac), the new structure will replace the original span, which opened in 1958. The replacement bridge, which is scheduled for completion in 2016, is the centerpiece of a $2 billion program to reconstruct and widen 13 miles of I-95 between West Haven and Branford. The overall project is part of the New Haven Harbor Crossing Corridor Improvement Program, one of the largest, most comprehensive transportation programs ever undertaken in Connecticut. The Q-Bridge carries I-95 over New Haven Harbor at the confl uence of the Quinnipiac and Mill rivers. The current structure accommodates three lanes of traffi c in each direction with no inside or outside shoulders. Ini- tially designed to handle 40,000 vehicles a day, it now carries more than 60,000, and its volume is expected to increase to 140,000 by 2015. The Con- necticut Department of Transportation (CTDOT) identifi ed the area through which the bridge passes as the largest bottleneck in the state. Excessive volume is not the only problem.

  • A Study of Various Types of Bridges in India with Historical Perspective
    Journal of Advances and Scholarly Researches in Allied Education Vol. XIV, Issue No. 2, January-2018, ISSN 2230-7540 A Study of Various types of Bridges in India with Historical Perspective Manjeet* Guest Faculty/Resource Person, Department of Civil Engineering, U.I.E.T. M. D. University, Rohtak Abstract – Bridges are structures which are built over an obstacle like valley, water or road with the purpose of making a transportation route. Bridges lay horizontally between some types of supports. These are used for transportation of vertical loads. The important aspect of a bridge is that it does not provide any kind of hindrance to the route beneath it. In the beginning bridges were very simple structures that were built from easily accessible natural resources- wooden logs, stone and dirt. Because of that, they had ability only to span very close distances, and their structural integrity was not high because mortar was not yet invented and rain slowly but constantly dissolved dirt fillings of the bridge. Evolution also came in the field of Bridge construction. They can be classified in many ways, such as on the basis of the construction material used, the style, or the mechanism for holding weight, etc. However, they are most commonly differentiated on the basis of their mechanism for bearing weight. The present paper is an attempt to study the various types of bridges in India namely cantilever bridges, arched bridges, extradosed bridges and cable-styled bridges and their history. Key Words: Bridge, cantilever bridge, arched bridge, extradosed bridge and cable-styled bridge. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - X - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - HISTORY OF INDIAN BRIDGES: Suspension bridge (150m to 2000m span) etc.

Stroh, AECOM 0.8 for conventional cast-in-place-on- falsework construction to about 0.65 for balanced-cantilever construction. A review of worldwide data on extradosed bridges shows that L1/L varied from 0.33 to 0.83 with a mean of 0.57.1 The standard deviation is 0.12, so one standard deviation each side of the mean gives a range for L1/L of 0.45 to 0.69. This places extradosed bridges essentially between the envelopes of concrete cable-stayed bridges and The Odawara Port Bridge, Japan, is the world’s first extradosed prestressed concrete balanced-cantilever-constructed concrete- bridge, completed in 1994.

Extradosed prestressed concrete bridges Based on these data, a range from 300 Multi-span are a relatively new development in bridge to 600 ft is shown to be a common span Bridge Application engineering, with only about 60 of these range for typical bridges of this type, with Cable-stayed bridges are typically either completed worldwide. The extradosed span range applicability of 200 to 900 ft. two-span or three-span arrangements. prestressed concrete bridge has the These span arrangements are ideal for appearance of a cable-stayed bridge with Side Span Ratios cable-stayed bridges because back stay “short” towers, but behaves structurally The ratio between the main span length, cables can be provided from the anchor closer to a prestressed concrete girder L, and the side span length, L1, has an piers to the top of the towers to provide bridge with external prestressing.
