Section 555. — STEEL STRUCTURES

07/20/15–FP14

Description

555.01 Delete the text of this Subsection and substitute the following:

This work consists of providing a fully engineered and prefabricated steel bridge. It includes designing, furnishing, fabricating, delivering, and erecting the bridge superstructure, bridge timber deck, bearing devices, and all appurtenances.

Construction Requirements

555.03A Design (Added Subsection).

(a) Design Features. Perform structural design of the bridge structure, footing, and micropiles by or under the direct supervision of a Licensed Professional Engineer, registered in the State of Washington, and in accordance with recognized engineering practices and principles.

Provide a modular design that employs steel beams or hollow structural sections (HSS) as the main load carrying members. Design and fabricate the bridge such that the components may be assembled in the field with basic tools and skills. Make all field connections using high strength bolts.

Furnish all necessary bearing assemblies, anchor bolts, and connectors to fully assemble the bridge on timber sills.

Design the bridge as a Steel Truss Span. Furnish a bridge with 125 feet overall length horizontal rail safety system per plans. The minimum bridge width is 12 feet rail-to-rail.

Provide 54” railing above the floor deck. Provide Continuous vertical pickets located on the inside of the trusses. Maximum opening between pickets is 4”.

Coat all steel components with shop-applied inorganic zinc primer or hot dip galvanize.

Completely coat all steel, including top surface of girder flanges. Use connection details for installing the decking without damaging the coating on the girders. Do not mask faying surfaces prior to painting.

Rig main superstructure components with lifting devices to facilitate efficient installation of the bridge using hand labor, light duty equipment (rubber tire backhoe). Place lifting devices so as not to interfere with traffic utilizing the structure, or make provisions to remove the lifting devices after the bridge is assembled in place.

(b) Design Criteria. Design the bridge according to AASHTO LRFD Bridge Design Specifications, Current Edition, with Interim Specification. Use design live load according to AASHTO Guide Specifications for Design of Pedestrian Bridges. In addition, check for the following load combinations: DL + 5000 lb live load point load; DL + 35 psf snow load.

Design for maximum live load deflection of L/500.

For basis of footing design, the maximum allowable stress does not exceed the values listed on the plans.

555.03 Drawings and Diagrams. Amend as follows:

(a) Fabrication drawings. Add the following:

Prepare drawings to adequately fabricate and erect the bridge. This includes, but is not limited to, bridge detail plans including girder and deck member dimensions, anchor bolt layouts, footing details, erection drawings and instructions.

Include in the General Notes the following information: design specification and method used (LRFD, LFD, ASD); assumed dead and live loads; live load deflection criteria; steel grade(s);

timber grade and allowable bending stress; and any other information necessary to perform an independent structural check of the design. Furnish erection instructions including a full list of bridge components, hardware, and fasteners and an erection plan identifying pieces by piece mark and location in the structure.

For manufactured components other than rolled steel members, or sawn lumber, indicate on the drawings the relevant section properties (such as location of neutral axis, and moment of inertia or section modulus), as well as recommended maximum loading if given by the manufacturer, to allow a structural analysis of those components.

Affix the seal and signature of a professional engineer proficient in bridge design in the State of Washington to the final acceptance drawings (record set) and calculations.

(d) Transportation drawings. Add the following:

Coordinate and schedule the delivery with the CO at least 14 days prior to shipping the bridge.

555.07 Fabrication. Delete the text of the first sentence of the first paragraph and substitute the following:

Fabricate the structural steel in a fabricating plant that is certified in: SBR IBR (Certified Bridge Fabricator - Simple Intermediate) under the AISC Quality Certification Program.

555.14 Preassembly of Field Connections. Add the following to the first paragraph.

Assemble the bridge at the fabrication shop prior to delivery to ensure proper fit-up of all components. Provide the CO 3 days’ notice prior to this action. Disassemble the bridge and transport the bridge in sections.
