Provide a response to the following: 1.) detailed and specific explanation/rationale of the requested change(s)to the task(s) and/
or the additional days added (if requested); 2.) why this change was not included in the original contract; and, 3.) describe the
impact if this change is not processed. Attach additional information from the Design Professional and/or Contractor if needed.
This change order is required to revise the bid specifications.The recommended changes are as follows:
• Add Line items 1 through 9:Adding wire sizes 10-1 gauge, 12-1 gauge,and 14-1 gauge($22,325.28)
(1)The change being requested is to add 10, 12, and 14 gauge wire that will connect to an existing Motorola AC controller located
at Fiddler's Creek and will provide connection to the farthest valve south. The cost includes trenching and installation of the
additional wires.
(2)The various sized wires were not included in the contract because the irrigation was originally designed with the new Motorola
DC controllers that required less wire.
(3) If the change is not made,the irrigation system will not operate or communicate with the existing Motorola AC controller at
Fiddler's Creek.
• Add Line items 10 through 12: Add a 3"SDR 11 Directional Bore to encase the wires($3,208.50)
(1)The change being requested to add the 3"directional bore between medians. The 3" conduit is needed to accommodate the
additional larger size wire bundle.
(2)The 3" SDR 11 directional bore was not included because in the original design because less wire was required.
(3) If the change is not made,the additional wire will not fit in the existing conduit.
• Add Line items 13 through 15:Add connection and mapping of irrigation wires to the existing Motorola AC controller
($958.45) /
(1)The change being requested is for the connection and mapping of wires to the existing Motorola AC controller at Fiddler's
Creek.
(2)The additional work was not included since the Motorola DC controller requires less wires and does not require additional
connections and mapping.
(3) If the change is not made,the wires will not be properly mapped and connected to the existing Motorola AC controller.
• Delete Line item 67: Delete the proposed Motorola DC power, 2-Station Piccolo Controller(-$1,675.00) ''"'
(1)The change being requested is to delete the proposed Motorola DC power 2—Station Piccolo Controller.
(2) Due to recent product standardizations, the Motorola DC Piccolo controller is no longer being used.
(3) If the change is not made,this roadway would need to be converted to a Motorola AC controller(M unit)to meet the new
standard at a later date incurring more cost.
• Delete Line item 68: Delete the proposed Motorola DC power 4-Station Piccolo Controller(-$7,560.00)
(1)The change being requested is to delete the Motorola DC power 4—Station Piccolo Controller.
(2) Due to recent product standardizations,the Motorola DC Piccolo controller is no longer being used.
(3) If the change is not made,this roadway would need to be converted to a Motorola AC controller(M unit)to meet the new
standard at a later date incurring more cost.

(1)The change being requested is to delete the primary and spare control solid wires because the new design utilizes an
existing Motorola AC controller requiring additional wires of multiple sizes.
(2)The different sized wires were not included in the original bid schedule because the project was designed for a Motorola DC
controller which requires less wire to operate the irrigation system.
(3)If the change is not made,there will not be enough wires to properly operate the existing Motorola AC controller and the
irrigation system will not meet the new standard.

Proposed Irrigation Control System Change
DATE: January 12,2017
TO: Mr. Scott Windham,RLA—Windham Studio.
FROM: James C.Abney,JCA-IC.
PROJECT: Collier Boulevard(S.R. 951)—Collier County,Florida
SUBJECT: Proposed Irrigation Control System Change Review/Study
As a result of recently considering connecting the proposed irrigation design zones to an existing controller located near
the northern end of the north median, study to evaluate the feasibility of connecting to the existing controller has been
prepared.Below are the subject related observations.
OBJECTIVE
Primary Objective: The primary will be to eliminate the use of the Motorola Piccolo units proposed in the design, and
study the economic feasibility to connect to an existing controller located nearby.
CHALLENGES
Existing Landscape: To get to the existing controller the proposed zones+hydrometer control wires will have to be
installed trenching through existing landscape. The existing landscape has been in the ground for several years,
approximately 10+/-years.
Planting bedlines of ornamental grasses primarily meander throughout the median. The plantings are mature, slightly
beyond their prime; some showing signs of decay,but most are in satisfactory condition.
There are sections of turf grass that meander throughout the median.The turf grass is in fair to poor condition due to
irrigation coverage interference by the plantings, also more than likely insufficient irrigation coverage applications
(primarily due to surface runoff losses), and also very likely due to existing soil conditions(highly alkaline with poor
percolation/drainage).
Distance: The approximate distance in a straight line measure from the existing controller location to the project's limit
of work line(north limits line) is approximately 1600+/-L.F. Trenching in a straight line from the existing controller
location to the project's north limits line is not physically and feasibly possible due to large diameter palms(Royal
Palms)as well as mature trees occurring along the straight line(s)possible path(s).
• Existing Planting Bedlines Trenching; Trenching through the existing planting bedlines will create a highly
visible disturbance to the existing plant communities. The trenching through the planting bedlines communities
will present a significantly high cost that will not make the likely cost feasible for the project.Planting bedline
disturbance restoration will cost around$40,000.00+/-,depending on the width of the path(assume 5' width).

• Directional Bore Installation; Having a Directional Bore conduit installed will require at least a 3"DB conduit,
with a cost between$42,000.00 to 45,000.00,excluding the cost of the control wires.
• Turf Grass Trenching: Trenching through the turf grass will present the lowest existing landscape restoration
cost because it will present the least disturbance if done with a small trenching unit(set for an 18"+/-trench
depth,but it will present an increase in distance(control wire quantities)due to the turf grass meandering
throughout the median from side to side.A 15%+(250+/-L.F.)should be added to the 1600+/-L.F. distance. The
existing controller to project's north limits line distance to consider should be 1,850+/-L.F.
Control Wire Sizes: The length of the control wire required to reach from the existing controller location to the farthest
valve(at the south end,near the project's south limits line)will be around 4750+/-L.F. Such length will require the use
of a solid copper 10 Gauge ground wire and a solid copper 10 gauge active and spare wires.As the distance decreases the
size(gauge)of the active control wires can decrease.Note,as a wire diameter decreases,the nominal label size increases.
For example,a 10 gauge wire has a significantly larger diameter than a 14 gauge wire. Below is a table of recommended
control wires,and approximate lengths.

development entrance.The controller's electric service is provided by a single phase transformer located on a power pole
located on the west side of the Right of Way,parallel to the controller.
