The contractor must provide the following documentation, for any proposed supplier who is not pre-approved, at least 10 days prior to bid:

Product Literature Representative design calculations Representative drawings Splicing and erection procedures Warranty information Inspection and Maintenance procedures AISC Shop Certification Welder Qualifications

Proposed suppliers must have at least five (5) years experience designing and fabricating these type structures and a minimum of five (5) successful bridge projects, of similar construction, each of which has been in service at least three (3) years. List the location, bridge size, owner, and a contact for reference for each project. The engineer will evaluate and verify the accuracy of the submittal prior to bid. If the engineer determines that the qualifying criteria have not been met, the contractor's proposed supplier shall be rejected. The engineer's ruling shall be final.


GENERAL FEATURES OF DESIGN SP-3-3.1 The Bridge span shall be 54'-0" (straight line dimension) and shall be as measured from CL joint at begin bridge to CL joint at end bridge. Bridge width shall be 12'-0" and shall be as measured from the inside face of the safety railing elements. The bridge shall be designed as a Bowstring truss. The bridge shall be designed utilizing an underhung floor beam (top of floor beam welded to the bottom of the bottom chord) or be designed utilizing an H-Section configuration where the floor beams are placed up inside the trusses and attached to the truss verticals. The manufacturer shall maintain the distance from top of deck to bearing seat shown on the construction drawings. The top of the top chord shall not be less than 54 inches above the deck. SP-3-3.2 Member Components All members of the vertical trusses (top and bottom chords, verticals, and diagonals) shall be fabricated from square and/or rectangular structural steel tubing. Other structural members and bracing shall be fabricated from structural steel shapes or square and rectangular structural steel tubing. Unless the floor and fastenings are specifically designed to provide adequate lateral support to the top flange of open shape stringers (w-shapes or channels), a minimum of one stiffener shall be provided in each stringer at every floor beam location.

ATTACHMENTS SP-3-4.1 Safety Rails Vertical safety rails or pickets shall be placed on the structure to a minimum height of 4'-6" above the deck surface. The pickets shall be spaced so as to prevent a 4" sphere from passing through the truss. Pickets shall be placed on the inside of the structure. The picket safety system shall be designed for an infill loading of 200 pounds, applied horizontally at right angles, to a one square foot area at any point in the system. Pickets shall be fabricated to be plumb in the finished condition, not perpendicular to the bottom chord.

SP-3-4.2 Toe Plate The bridge shall be supplied with a steel toe plate mounted to the inside face of both trusses. The toe plate shall be a minimum of 4 inches high. Toe plating will be welded to the truss members at a height adequate to provide a 2 gap between the bottom of the plate and the top of the deck or the top of the bottom chord, whichever is higher. The span of unstiffened flat toe plating (from center to center of supports) shall not exceed 5-8.

SP-3-4.3 Camber The bridge shall have a vertical camber dimension at midspan equal to 100% of the full dead load deflection.

ENGINEERING AND DESIGN LOADING


SP-3-5.1 Structural design of the bridge structure(s) shall be performed by or under the direct supervision of a Licensed Professional Engineer and done in accordance with recognized engineering practices and principles. The design of the bridge shall conform to the requirements of the AASHTO LRFD Guide Specifications for Design of Pedestrian Bridges (2009).

SP-3-5.2 Dead Loads The bridge structure design shall consider its own dead load (superstructure and original decking), as well as the additional loads listed below: SP-3-5.3 Pedestrian Live Load Main Members: Main supporting members, including girders, trusses and arches shall be designed for a pedestrian live load of 90 pounds per square foot of bridge walkway area, with no reduction allowed. The pedestrian live load shall be applied to those areas of the walkway so as to produce maximum stress in the member being designed. Secondary Members: Bridge decks and supporting floor systems, including secondary stringers, floor beams and their connections to main supporting members shall be designed for a live load of 90 pounds per square foot, with no reduction allowed.

SP-3-5.4 Truck Load

A 20,000 pound (AASHTO H-10) four wheeled vehicle shall be used for the truck loading. The wheel loads for this vehicle shall be 2,000 pounds and 8,000 pounds for the front and rear axles, respectively. The wheel loads shall be assumed to be spaced 6 feet apart transversely. The distance between the front and rear axles shall be assumed to be 14 feet. The truck shall be positioned 2 feet from the face of the truss to determine the distribution of loading carried by each truss.

All of the concentrated or wheel loads shall be placed so as to produce the maximum stress in each member being analyzed. Critical stresses need be calculated assuming there is only one vehicle on the bridge at any given time. Assumptions that vehicles only travel down the center of the bridge or that the vehicle load is a uniform line load will not be allowed. A vehicle impact allowance is not required.

SP-3-5.5 Wind Loading The bridge shall be designed for a wind load of 35 pounds per square foot on the full vertical projected area of the bridge as if enclosed. The wind load shall be applied horizontally at right angles to the longitudinal axis of the structure. The wind loading shall be considered both in the design of the lateral load bracing system and in the design of the truss vertical members, floor beams and their connections. The effect of forces tending to overturn structures shall be calculated assuming that the wind direction is at right angles to the longitudinal axis of the structure. In addition, an upward force shall be applied at the windward quarter point of the transverse superstructure width. This force shall be 20 pounds per square foot of deck.


SP-3-5.6 Stream Force The bridge shall be designed for a lateral stream force as required by the AASHTO LRFD Bridge Design Specifications (6 Ed.). The stream velocity for the 100 year design storm is 10 fps. Calculation of the stream force shall assume that the bridge structure is completely blocked with debris. SP-3-5.7 Combination of Loading Combinations of loads, allowable stresses for service load design, and load factors for load factored design shall conform to the AASHTO LRFD Guide Specifications for the Design of Pedestrian Bridges (2009).

DESIGN LIMITATIONS

SP-3-6.1 Vertical Deflection The vertical deflection of the main trusses due to service pedestrian live load shall not exceed 1/360 of the span. The vertical deflection of cantilever spans of the structure due to service pedestrian live load shall not exceed 1/220 of the cantilever arm length. The deflection of the floor system members (floor beams and stringers) due to service pedestrian live load shall not exceed 1/360 of their respective spans. The service pedestrian live load shall be 90 PSF. Deflection limits due to occasional vehicular traffic shall not be considered.

SP-3-6.1 Vibration The fundamental frequency shall meet the requirements of the AASHTO LRFD Guide Specifications for the Design of Pedestrian Bridges (2009). SP-3-6.2 Horizontal Deflection The horizontal deflection of the structure due to lateral wind loads shall not exceed 1/500 of the span under a 35 PSF wind load. SP-3-6.3 Minimum Thickness of Metal The minimum thickness of all structural steel members shall be meet the requirements of the AASHTO LRFD Guide Specifications for the Design of Pedestrian Bridges (2009). For ASTM A500 and ASTM A847 tubing, the section properties used for design shall be per the Steel Tube Institute of North America's Hollow Structural Sections "Dimensions and Section Properties".

The minimum corrosion index of atmospheric corrosion resistant steel, as determined in accordance with ASTM G101, shall be 6.0.


SP-3-6.2 Concrete Deck The bridge shall be furnished with a stay-in-place, non-composite, galvanized steel form deck suitable for pouring a reinforced concrete slab. The form deck shall be designed to carry the dead load of the wet concrete, weight of the form decking, plus a construction load of 20 PSF uniform load or a 200 pound concentrated load on a 1-0 wide section of deck. When edge supports are used, deflection is limited to 1/180 of the span or 3/4, whichever is less. Without edge supports, deflection shall be limited to 1/180 of the span or 3/8, whichever is less. The form deck material shall be supplied in accordance with ASTM A653 and galvanized to a minimum G90 coating weight. The deck slab shall be constructed using Class S(AE) concrete with a minimum 28-day strength of 4000 psi. Concrete deck design shall be performed by the bridge manufacturer. Concrete decks shall be designed for concentrated loads as specified above.

SP-3-6.3 Welding Welding and weld procedure qualification tests shall conform to the provisions of ANSI/AWS D1.1 “Structural Welding Code”, 1996 Edition. Filler metal shall be in accordance with the applicable AWS Filler Metal Specification (i.e. AWS A 5.28 for the GMAW Process). For exposed, bare, unpainted applications of corrosion resistant steels (i.e. ASTM A588 and A847), the filler metal shall be in accordance with AWS D1.1, Section 3.7.3. Welders shall be properly accredited operators, each of whom shall submit certification of satisfactorily passing AWS standard qualification tests for all positions with unlimited thickness of base metal, have a minimum of 6 months experience in welding tubular structures and have demonstrated the ability to make uniform sound welds of the type required.

SUBMITTALS SP-3-7.1 Submittal Drawings Schematic drawings and diagrams shall be submitted to the Engineer for their review after receipt of order. Submittal drawings shall be unique drawings, prepared to illustrate the specific portion of the work to be done. All relative design information such as member sizes, bridge reactions, and general notes shall be clearly specified on the drawings. Drawings shall have cross referenced details and sheet numbers. All drawings shall be signed and sealed by a Professional Engineer who is licensed in accordance with Section 3.0. SP-7-7.2 Structural Calculations Structural calculations for the bridge superstructure shall be submitted by the bridge manufacturer and reviewed by the approving engineer. All calculations shall be signed and sealed by a Professional Engineer who is licensed in accordance with Section 3.0. The calculations shall include all design information necessary to determine the structural adequacy of the bridge. The calculations shall include the following:

All AASHTO LRFD design checks for axial, bending and shear forces in the critical member of


each truss member type (i.e. top chord, bottom chord, floor beam, vertical, etc.). Checks for the critical connection failure modes for each truss member type (i.e. vertical,

diagonal, floor beam, etc.). Special attention shall be given to all welded tube on tube connections.

All bolted splice connections. Main truss deflection checks. U-Frame stiffness checks (used to determine K factors for out-of-plane buckling of the top chord)

for all half through or "pony" truss bridges. Deck design.

NOTE: The analysis and design of triangulated truss bridges shall account for moments induced in members due to joint fixity where applicable. Moments due to both truss deflection and joint eccentricity must be considered. Welder certifications in compliance with AWS standard qualification tests. Welding procedures in compliance with Section 5.1.

FABRICATION SP-3-8.1 Drain Holes When the collection of water inside a structural tube is a possibility, either during construction or during service, the tube shall be provided with a drain hole at its lowest point to let water out. SP-3-8.2 Welds Special attention shall be given to developing sufficient weld throats on tubular members. Fillet weld details shall be in accordance with AWS D1.1. Unless determined otherwise by testing, the loss factor “Z” for heel welds shall be in accordance with AWS Table 2.8. Fillet welds which run onto the radius of a tube shall be built up to obtain the full throat thickness. The maximum root openings of fillet welds shall not exceed 3/16” in conformance with AWS D1.1, Section 5.22. Weld size or effective throat dimensions shall be increased in accordance with this same section when applicable (i.e. fit-up gaps> 1/16”).

The fabricator shall have verified that the throat thickness of partial joint penetration groove welds (primarily matched edge welds or the flare-bevel-groove welds on underhung floor beams) shall be obtainable with their fit-up and weld procedures. Matched edge welds shall be “flushed” out when required to obtain the full throat or branch member wall thickness. For full penetration butt welds of tubular members, the backing material shall be fabricated prior to installation in the tube so as to be continuous around the full tube perimeter, including corners. Backing may be of four types:

A “box” welded up from four (4) plates. Two “channel” sections, bent to fit the inside radius of the tube, welded together with full

penetration welds. A smaller tube section which slides inside the spliced tube. A solid plate cut to fit the inside radius of the tube.


Corners of the “box” backing, made from four plates, shall be welded and ground to match the inside corner radii of the chords. The solid plate option shall require a weep hole either in the chord wall above the “high side” of the plate or in the plate itself. In all types of backing, the minimum fit-up tolerances for backing must be maintained at the corners of the tubes as well as across the “flats”. SP-3-8.3 Quality Certification Bridge(s) shall be fabricated by a fabricator who is currently certified by the American Institute of Steel Construction to have the personnel, organization, experience, capability, and commitment to produce fabricated structural steel for the category “Major Steel Bridges” as set forth in the AISC Certification Program. Quality control shall be in accordance with procedures outlined for AISC certification. For painted structures, the fabricator must hold a "Sophisticated Paint Endorsement" as set forth in the AISC certification program. Furthermore, the bridge(s) shall be fabricated in a facility owned and/or leased by the corporate owner of the manufacturer, and fully dedicated to bridge manufacturing.

FINISHING SP-3-9.1 Blast Cleaning All Blast Cleaning shall be done in a dedicated OSHA approved indoor facility owned and operated by the bridge fabricator. Blast operations shall use Best Management Practices and exercise environmentally friendly blast media recovery systems. To aid in providing a uniformly “weathered” appearance, all exposed surfaces of steel shall be blast cleaned in accordance with Steel Structures Painting Council Surface Preparation Specifications No. 7 Brush-Off Blast Cleaning, SSPC-SP7 latest edition.
