Exhibit#1a (Scope of Work) WO#2 12/29/2015 Gravity Sewer Design For Study Area 2 Page 2 File#1422LE • The area of Roseland between Roseland Road and the Saint Sebastian River from Kelso Place to 128th Court. The project will increase flows into two (2) of the existing County Utilities' pump stations along Indian River Drive. Our services will include evaluation of these pump stations and, if necessary, design of required modifications. In addition, our services will include design of an interconnection of the Indian River Drive force main and the railroad force main in the vicinity of Truman Street. This will improve the Indian River Drive force main system performance. The estimated number of existing and future Equivalent Residential Units (ERUs) which can be connected to this proposed project is 332 and 58, respectively. The estimated total construction cost of this project is $1,990,000.00. A specific list of tasks and their brief description is presented as follows: Task A—Civil Engineering Services Masteller & Moler, Inc. will provide final design, prepare construction plans and permit applications for the project as described in the "Scope of Services" section of this proposal. Task B—Surveying Services The approximate length of the right-of-way limits is 21,100 linear feet (3.98 miles). Masteller, Moler& Taylor, Inc. will perform surveying services for the project as follows: 1) Project initiation, including review of existing deeds and surveys, files and field notes, preparation of work orders and field crew folders. 2) Find, recover and measure field ties into existing survey control along the route to establish the rights of way and baseline of survey. Tie Horizontal Control to Florida State Plane Coordinate System, Florida East Zone, NAD '83. 3) Find and recover existing vertical control. Elevations shall be based upon the North American Vertical Datum of 1988 (NAVD '88) with a conversion to the National Geodetic Vertical Datum of 1929 (NGVD `29) provided. Perform bench run and establish benchmarks along the survey corridor at maximum 1,000 foot intervals. 4) Field monument baseline control at maximum 1,000 foot intervals. Control points shall consist of iron rod and cap or nail and disk. Control points shall be designated on survey with station/offset and NAVD `88 elevation. 5) Field locate and record vertical ground elevations sufficient to generate a center line of road profile for the main corridor and side streets and all distinct locations (inverts, retention areas, swales, ditches etc.) and changes in contour along the right of way corridor. Obtain ground elevation on each property in center of lot if vacant or near existing septic location to the best of our abilities. If septic location not obtainable, obtain ground elevation near existing main building. 6) Field locate and record existing improvements and man-made features within the right of way, including but not limited to, roads, swales, driveways, culverts, signage and mailboxes, visible utilities, fences etc. within the existing right-of-way.
