1.6 DESIGN

The performance of design-associated work is planned to include the following items:

Survey & Right-of-Way

• Conduct surveys (field and aerial as deemed necessary) to obtain topography and locate above-ground improvements pertinent to the design. All survey shall be referenced to the North American Vertical Datum of 1988 (NAVD 88) for vertical control and the Florida State Plane Coordinate System, East Zone, NAD 83 for horizontal control.

• Survey to locate the following within the proposed right-of-way and a minimum 20-foot wide strip along each side of the proposed right-of-way: topography, above-ground utilities or their marks, above-ground improvements pertinent to the design, drainage system, and finish floor elevation for buildings within 50 feet of the proposed ROW. Major improvements (such as buildings) within a 50-foot wide strip along each side of the proposed right-of-way also need to be located.

• Stake-out location for design-related testing.

• Prepare legal descriptions and sketches for the acquisition of the required right of way and drainage retention areas, Temporary Construction Easements and Public Easements.

Right-of-Way Acquisition Support

• Coordinate with surveyor for preparation of right-of-way acquisition sketches and legal descriptions

• Verify that surveyor's sketches and legal descriptions match property needs shown in design plans

• Prepare table of all parcels to be acquired, including acreage for:

– Fee simple right-of-way

– Drainage easements

– Permanent slope easements

– Temporary construction easements

– Any other easements required

Roadway Design

• Prepare final construction plans for the proposed roadway and intersections. Plans will include, but not be limited to, the following:

Drainage Design

• Prepare drainage designs to provide stormwater management for the proposed roadway. This does not include designs to resolve existing offsite drainage problems. Portions of the project corridor traverse FEMA

Flood Zone AE and Zone X.

• The County currently owns and maintains three (3) Drainage Retention Areas (DRAs) along the project corridor. Two DRAs are located within Parcels 13205-001-00 and 13144-003-00. The third DRA is located within the right-of-way of the horizontal curve just south of Parcel 13155-001-00. The consultant shall evaluate the capacity of the existing DRAs and determine whether they are sufficient to accommodate stormwater runoff from the widened roadway or whether improvements or additional DRAs are needed.

Existing design plans for the DRAs are included with this RFQ.

• Work included in the Scope includes:

– Collect and review available drainage data, including existing drainage maps

– Delineate drainage areas on aerial maps

– Design drainage system per applicable standards and criteria from WMD, County, or as approved by the OCE

– Account for applicable FEMA floodplain requirements. Determine whether a FEMA Letter of Map

Revision (LOMR) or other floodplain management documentation is required as part of the project permitting.

– Provide details for non-standard drainage structures

– Drainage maps and details will be incorporated into, and become an integral part of, the overall roadway plans

– Soil boring locations for the DRAs shall be identified on the DRA sheets. The boring logs shall be included in the set of plans

– Existing improvements, including storm drainage, will be shown and labeled, as appropriate, on the plan view of the plan and profile sheets. Existing improvements to remain shall be labeled accordingly.

Existing Utilities

New Utility Design Depiction

• The City of Ocala, Marion County Utilities, or other utility owners may elect to install new utilities in conjunction with this project. However, the preparation of conceptual and detailed, designs and construction notations, instructions, and specifications for the proposed utilities and obtaining all applicable permits will be independent of this project and be the responsibility of the utility owner.

• Incorporate and depict proposed utilities, as provided, into the base drawing for the roadway design.

• Coordinate with designers for the various utility systems to avoid conflicts

• Notify the Office of the County Engineer of unresolved underground conflicts and coordinate conflict resolution

Signs and Pavement Markings

• MOT plans shall be in accordance with the requirements contained in the "State of Florida Manual on

Traffic Controls and Safety Practices for Street and Highways Construction, Maintenance and Utility

Operations"

• The MOT and Sequencing plans are to be presented at the 90% design stage in a preliminary and schematic format. More detail, if necessary, will be presented in subsequent design stages.

• The scope and detail of the MOT and Sequencing Plans shall be sufficient for bidders to estimate the work effort required

Quantity Estimation

Marion County Office of the County Engineer Page 9 of 10

• Compute the quantities of all materials required for construction and prepare a pay item schedule listing the various construction details. Quantity Takeoffs to be presented at the 60%, 90%, 100%, and Final stages of design.

• Furnish engineer's estimate of probable construction cost at 30%, 60%, 90%, 100%, and Final stages

The 30% cost estimate shall be based on parametric or unit cost methods using recent comparable project data. Detailed cost estimates shall be prepared at the 60%, 90%, 100%, and Final stages.
