AGREEMENT 1-2354 Exhibit A engineering and architectural design shall be done on CADD in the format compatible with the Conceptual Engineering phase. ' Working from permanently monumented primary control points outside the.zone of any expected construction activity on The CenterLine Project, the CONSULTANT shall establish secondary and permanently monumented control points along the CenterLine alignment at approximately I,OW-foot intervals. The secondary control points shall be tied into the primary cóntrol points with an accuracy of I :50,000. The secondary control points should be located just outside the zone of expected CenterLine project construction. Mapping will show all existing major utilities and any other significant features. Where necessary, enlarged details and cross-sections shall be prepared to assure against unacceptable' conflicts. Planned utility improvements shall be added as they are encountered. Additional field surveys will be perfoffi1ed to obtain elevations of overhead power lines, bottom of overhead stmctmes and other design data not illustrated on base mapping."~ , Engineering drawings of the PE alignment shall be done at 1"=40' scale. To the extent possible, the alignment at this level of design is to be within one foot, horizontal and vertical, of its final location. The mapping will be screened so that the project work is readily identified. Station areas including the entire parking lot shall be drawn at 1"=20' scale. The base maps will show all existing streets, buildings, other significant features, and property lines within the station area. They shall be screened so that the station design is readily decipherable. For stations without parking lots, the platform and its surrounding area shall be at 1"=20' scale. There shall be a plan prepared for each station. These drawings will identify all station-related stmctures including canopies/shelters, communication buildings, traction power substations, bus loading areas, pedestrian paths, etc. Right-of-way boundaries will be delineated and, to the extent possible, be within 2 feet of the expected final right-of-way needs. The Central Maintenance Facility and yard (CMF) shall be designed at a 1"=20' scale. The mapping will be screened and show all existing structures, buildings, other significant features, roadways, and property lines. All yard track work, stmctures, power substations, car wash facilities, fuel storage/pumping stations, roadways, parking areas, etc" will be shown. The following paragraphs describe in greater detail the work scope that resulted CONSULT ANT's input during negotiations of the PE consulting services contract. from the The following clarifications are included as part of the CONSULTANT's Schedule ofYalues: Task 2,01 Mapping . CONSULT ANT's project schedule is based on a 9O-day aerial mapping process, Task 2.02 Additional Field Surveys 14 - --~ ()lI"
