EXHIBIT “A”

Proposal for Redevelopment of a Covered Observation Deck

Task Assignment #16 – Change Order #1 Contract Number CN304

Introduction: This proposal is for finalizing the design and permitting services as well as the construction services associated with the reconstruction of an observation deck located at Weekie Wachee Springs State Park in Hernando County, FL. The state park is located at 6131 Commercial Way in Weekie Wachee, FL 34606 (Parcel ID R-Z SWM 17- 0000-0030-0000). A detailed breakdown and description of individual task efforts is listed below.

GPI provide design and permitting services for replacing the observation deck overhanging Weekie Wachee Spring, at Weekie Wachee Springs State Park. The platform currently serves as a queuing area for patrons waiting to enter the mermaid theatre for the upcoming show. The platform is currently cantilevered over the spring and has fallen into a state of disrepair over the years.

The park wishes to reconstruct the deck, ideally without the cantilever overhanging the spring that currently exists as a cost saving effort. The park also wishes to cover the deck with an overhead hip-roof style pavilion or other pre-engineered covering. It is understood that the proposed infrastructure will be limited to the size of the existing deck’s footprint, and therefore no additional stormwater permitting, civil site permitting, or design shall be required.

Change Order #1: As discussed in our meeting 05-31-23, GPI shall coordinate additional geotechnical investigation for guidance related to the structural foundation design to address the potential sink hole activity. This will require a redesign/update of the plans including project management for the various disciplines.

Task 1: Permitting

Description: This task assumes that the contractor will apply for the building permit. It is anticipated that the County will have comments during this permitting process, and this task includes 2 reasonable responses to RAI’s. This task assumes no additional disturbance to the flood zones or wetlands located onsite, and therefore no coordination with FEMA or the ACOE. This task also assumes that the proposed structure will occupy the same (or lesser) footprint, and will therefore not require Civil Site Plan permitting, environmental permitting, or permitting with the water management district. A diagrammatic site plan is expected to be required for building permitting.

It is anticipated that the Hernando County Building Permit fee shall be paid by the contractor when the permit is picked up.

As requested, this task will include additional permit requirement verification.

Deliverables:

Preparation and electronic submittal of Hernando County Building Permit Application forms and supporting documentation in PDF format.

Provide written responses and plan revisions necessary to accommodate Hernando County permitting

Comments

Performance Measure:

Deliverables will be reviewed by the Department to confirm they are complete, accurate, and timely.

During that investigation, one boring adjacent to the proposed structure identified potential sinkhole activity. This task includes geotechnical engineering support to address concerns regarding the soil conditions near the structure. No additional soil borings or lab testing are proposed. This report includes providing recommendations for mitigating sinkhole risk to the proposed structure and providing a report addendum letter with proposed recommendations for design and construction beyond those already provided in our previous report.
