FIRST STREET PEDESTRIAN IMPROVEMENTS PS&E RFP NO.: 10-110 southern limits of survey at all remaining intersections along the limit of work will extend 100 feet past the curb returns at each intersection. The topographic survey will identify horizontally and vertically existing facilities and features within the limit of work includ- ing median islands, trees, curb & gutter, curb ramps, curb returns, sidewalk, driveways, bus pads, grade breaks, right-of-way, manholes, utility vaults and boxes, utility cabinets and equipment, street and traffic lights, utility poles, fire hydrants, drainage structures, survey monuments, street furniture, signage, fencing, and building faces constructed in close proximity to the right-of-way. Storm drain catch basin and manhole will be dipped to record invert elevations where manhole lids are not bolted down. The dipping of sewer manhole and other utility struc- tures is not included in this scope of work. In addition to the above items, centerline cross -sections will be provided at 100-foot intervals. Contours will be dis- played at half -foot intervals. It is assumed traffic con- trol will not be required to perform the topographic survey. Electronic base maps will be prepared in US Customary English Units by a California Licensed Land Surveyor. The survey will comply with the City's guidelines, and the final survey file deliverable will be provided in MicroStation V8i Computer Aided Design and Drafting (CADD) format. Survey control will be tied horizontally to the North American Datum of 1983 (NAD83) through GPS post processing constrained to the California Spatial References Center, Epoch 2017 Control. Vertical control will be tied to the North American Vertical Datum of 1988 (NAVD88) by occupation of the nearest City of Santa Ana or NGS benchmark controlled by that datum. If the benchmark used is not within site distance of the project, a local survey benchmark will be established for use during construction. The Property Line surveys will be performed to establish the limits of the public right-of-way in the vicinity of the project. Sufficient boundary monumentation will be recovered to orient a survey boundary, compiled from record documents. Additional available easements will also be plotted. A full boundary establishment survey is not believed to be necessary and is not included at this time. TASK 3.0 PS&E (30%, 60%, 95%, AND 100% SUBMITTALS) In order to meet the City's expectations, Tetra Tech will develop and deliver detailed Plans, Specifications and Estimates (PS&E) within four submittals. The 30% PS&E submittal package will be utilized to establish the conceptual design. The design will continue to be developed during the 60% and 95% PS&E submittals. The final 100% PS&E will be the final submittal package developed at a high level of accuracy ready for project advertisement. All submittal packages will include a complete set of plans, specifications, and cost estimate inclusive of the proposed improvements from each discipline covered in this section.
