The consultant will be required to coordinate work with City employees as needed. Typically, survey work shall start within two (2) weeks, and results/reports base plans shall be provided to the City Engineer for review within six (6) weeks of receiving a City-issued Notice notice to Proceed proceed for each Work Order. Urgent needs Surveyors and CAD technicians shall require work to be performed within available upon two (2) working days’ notice at the quoted hourly rates for potholing and construction phase work. Information provided by the City will include: • Electronic versions of mapping layers from the City GIS system for the project area. Although GIS based topographic information is available, it is not accurate enough for detailed design. • City-owned utility and As-Built records for the general area of the project upon request. • City of Mountlake Terrace CAD Standards • A list of benchmarks around the city, typically at monuments, based on NGVD1929 and NVD1988. Some project sites do not have monuments nearby due to loss from past construction activities. The work included in this contract may include, but is not limited to: Survey • Structure Stabilization (Retaining wallsCompiling and reviewing available information related to the project, foundation)‌ • Flexible and rigid pavement evaluation including plats, maps, GIS information, utility plans, easement documents, deeds, and design drawings • Settlement analysis Performing site reconnaissance • Establishment of benchmarks; horizontal and remediation vertical control • Shored Establishing bearings of the centerline of R/W and construction baselines, including curve data. • Topographical survey • Right-of-way location • Preparation of base plans • Generation of contours • Obtaining ground surface elevations of the roadway pavement from curb to curb to create elevation contours of the pavement surface, including the gutter and top of curb. • Obtaining existing features necessary for project design and construction, including grade breaks and other key features as needed for design of ADA compliant curb ramps and driveway entrances. • Incorporation of City-prepared design to base maps • Staking and marking for construction; installing PK nails in pavement along centerlines of right of way or braced excavation evaluations along construction baselines at 50 foot stations and obtaining elevations of each. • Foundation investigation and design‌ Survey duties in preparation for pot-holing or construction • Knowledge and expertise in groundwater modelingBoundary surveys • Prepare easement documents, hydrogeologylegal descriptions, and groundwater surface water interactions files and records of survey • Peer review Set monuments CAD • Preparation of slope stability calculations and related design submitted base maps which conform to City of Mountlake Terrace Engineering Services Department CAD Standards; does not include drafting profiles of the features shown in plan view.
