  • Appendix 5 Station Descriptions And
    Appendix 5 Station Descriptions and Technical Overview Stage 2 light rail transit (LRT) stations will follow the same standards, design principles, and connectivity and mobility requirements as Stage 1 Confederation Line. Proponent Teams were instructed, through the guidelines outlined in the Project Agreement (PA), to design stations that will integrate with Stage 1, which include customer facilities, accessibility features, and the ability to support the City’s Transportation Master Plan (TMP) goals for public transit and ridership growth. The station features planned for the Stage 2 LRT Project will be designed and built on these performance standards which include: Barrier-free path of travel to entrances of stations; Accessible fare gates at each entrance, providing easy access for customers using mobility devices or service animals; Tactile wayfinding tiles will trace the accessible route through the fare gates, to elevators, platforms and exits; Transecure waiting areas on the train platform will include accessible benches and tactile/Braille signs indicating the direction of service; Tactile warning strips and inter-car barriers to keep everyone safely away from the platform edge; Audio announcements and visual displays for waiting passengers will precede each train’s arrival on the platform and will describe the direction of travel; Service alerts will be shown visually on the passenger information display monitors and announced audibly on the public-address system; All wayfinding and safety signage will be provided following the applicable accessibility standards (including type size, tactile signage, and appropriate colour contrast); Clear, open sight lines and pedestrian design that make wayfinding simple and intuitive; and, Cycling facilities at all stations including shelter for 80 per cent of the provided spaces, with additional space protected to ensure cycling facilities can be doubled and integrated into the station’s footprint.

    Department of Forest Service Hardwoods: A Rev Southern Forest Experiment Station New Orleans, Louisiana General Technical Report SO-71 Terry Sellers, Jr., James R. McSween, and William T. Nearn Over a period of years, increasing demand for softwoods in the Eastern United States has led to an increase in the growth of hardwoods on cut-over softwood sites. tinfortunately these hardwood trees are often of a size and shape unsuitable for the production of high-grade lumber and veneer. They do. however. represent a viable. economic source of raw material for plywood, fiberboard, particleboard. and oriented strandboard lor flakeboards), all products that require the successful use of adhesives in their manufacture. The current status of gluing eastern hardwoods is reviewed in this report, with emphasis on hardwoods growing on southern pine sites. The subjects covered include adhesives, wood and wood-surface properties and their interactions with the adhesive, and the quality of the bonds produced when these hardwoods are used in the manufacture of end joints, laminates, plywood, and other composite panels. A variety of adhesives are available that equal or exceed the strength of the hardwoods being bonded. The choice of a particular adhesive is dictated in large measure by the adhesive price and the end-use criteria for the finished product. In discussing the gluing of eastern hardwoods, the approach taken is that the fundamentals that determine the quality of an adhesive bond should remain the same whether the substrate is a softwood or a low-, medium-, or high-density hardwood. To illustrate the differences encountered in gluing the various hardwood species and the best approach for dealing with them in terms of bonding fundamentals, in this report we will concex~trateon: The quality and character of the surface as aflected by wood structure.

    Canadian Consulting Engineering Awards 2013 Heron Road Bridge Rehabilitation Ottawa, Ontario Association of Consulting Engineering Companies Heron Road Bridge Rehabilitation 2013 Awards Ottawa, Ontario TABLE OF CONTENTS Confirmation Receipt Entry Consent Form PROJECT HIGHLIGHTS .................................................................................................. 1 PROJECT DESCRIPTION ................................................................................................ 2 TOC iii Association of Consulting Engineering Companies Heron Road Bridge Rehabilitation 2013 Awards Ottawa, Ontario PROJECT HIGHLIGHTS The Heron Road Bridge located in the nation’s capital, is a vital link within the City of Ottawa’s transportation network being one of several bridges crossing the Rideau River that divides the east and west parts of the City and one of three major east-west cross town routes. Constructed in 1966/1967, it consists of long twin structures carrying Heron Road over the Rideau Canal (National Historic Site of Canada and UNESCO World Heritage site), the National Capital Commission (NCC) pedestrian pathway, Colonel By Drive, the Rideau River, and the Vincent Massey Park access road. Part of the bridge collapsed during original construction and this tragedy remains one of Ontario’s worst construction accidents in history. Each structure consists of seven spans carrying three lanes of traffic. The north structure is about 267m long and the south structure is 276m long. The superstructure consists of cast-in-place post-tensioned voided concrete deck cantilevered to support three suspended spans. The suspended spans consist of nine simply supported prestressed girders, with reinforced concrete deck. The precast girders are supported by corbels at the ends of the cantilevered post-tensioned deck. The substructure consists of six intermediate piers and abutments at each ends. The piers in the vicinity of the Rideau River are supported on spread footing on bedrock whereas the remaining piers and abutments are supported by piles driven to bedrock.
