112 <br /> Diangl Ro'gioll'a l Project De l 0 Ip m In t Scope of Work <br /> Complete final alignment and profiles will be developed for the NEPA LPA at a scale of 1" = 40' <br /> horizontal and 1"=10' vertical using MicroStation software on a sheet size of 22"xc34". <br /> Conceptual plan and profiles will be developed for the New Hope Creek and Sandy Creek <br /> alternatives for use in evaluating the environmental impacts. Up to two alternatives are <br /> envisioned for the New Hope Creek and Sandy Creek alternatives. <br /> IN Coordinate of track design with other project design elements, especially grade crossing designs <br /> and station layouts. <br /> Develop rail and guideway sections for ballast and direct fixation track. The intent is for the <br /> typical sections to address the varying conditions along the alignment and hence will be <br /> indicated with stationing limits for each. <br /> Optimization track profile for cut and fill sections and coordinate roadway re-grading limits. <br /> Coordinate profile and special trackwork with proposed drainage and utility relocations designs <br /> and with the operation plan of the system <br /> Develop special trackwork details including emergency guard rail, turnouts, crossovers and end <br /> of line bumping posts. <br /> " Track design details for corrosion control and stray current control measures <br /> " Prepare alignment data sheets based on state plane coordinates or use of a local coordinate <br /> system,whichever is deemed most appropriate. <br /> Prepare of site specific cross sections @ 500' minimum and at places of critical changes in profile <br /> or conditions. <br /> IN Prepare track Charts showing a graphical representation of plan, profile, maximum speed limits, <br /> special trackwork, and signal locations <br /> 9.643 Grading, Retaining Wal1l1 and Fenchng IIDlans <br /> Using the same plan window as the plan and profile drawings, grading plans will be prepared showing <br /> cut and fill limits. Earthwork quantities will be placed directly on the drawings. The grading plans will <br /> include the station areas and parking area depicting the integration of the facilities into a cohesive set of <br /> plans. Corridor fencing will be shown on these plans as well based on Triangle Transit policies that will <br /> be discussed and developed during the design. It is anticipated that fencing will be limited to areas <br /> where it is likely that corridor control is necessary to prevent unwanted crossing of the tracks. In street <br /> running sections, a decorative type of fencing between the tracks will be used to channel pedestrians to <br /> crosswalks and to deter jaywalking across the tracks. Retaining walls will also be shown on these plans <br /> denoting their limits. The placement of retaining walls will be based on the track grading and will be <br /> coordinated with the site specific cross sections. <br /> 9.6.4 Dirainage Mans and Hydraullic Studies <br /> The work will include the collection of drainage data (both field and office); development of general <br /> project drainage schemes; design studies to detail drainage features with regard to location, type, size, <br /> material; and documentation of the design process and features through plans, profiles and reports. <br /> Il uurllhaurn- rar ge III,,,ig lht IlRaill Traurnsit Project � June 20:13 J -3 DIR IF„f <br />
