TO: Hannula Landscape & Irrigation Inc.
Attn: Dale Hannula, Owner
28131 Quails Nest Lane
Bonita Springs, FL 34135
DATE: April 18, 2013
PROJECT NAME: Radio Road East MSTU Landscape & Irrigation Project
PROJECT NO.: PO 4500136845
Under our AGREEMENT dated May 22, 2012
You hereby are authorized and directed to make the following change(s) in accordance with
terms and conditions of the Agreement:
INSTALLATION OF DRAIN HOLES TO ENSURE PERCOLATION
Description of Change: The installation of percolation drain holes was determined to be necessary in
order to ensure proper percolation in planted areas. The project specifications called for minimum
percolation rate of 2 inches per hour. Onsite inspection of each hole dug for trees indicated that a
percolation hole was required to be dug for 81 tree plantings.
Reason for Change: It is necessary for the plant health that percolation rate of 2 inches per hour be
achieved at the time of planting of all tree plant materials. Failure to ensure proper percolation rate
will result in the root-ball drowning in the hole it's planted within.
Cost Factor Evaluation: The cost of each percolation drain at $98.00 for a 4 ft. depth (48") and 8
inch diameter is considered to be acceptable and achieves the desired 2 inch per hour percolation rate.
Field investigations resulted in some modification to the specifications to allow for a reduced depth of
installation for each drain to be 4 ft. versus the original specification of 6 ft. depth. This adjustment
resulted in a reduction in unit cost for percolation drain installation.
ADD NEW TASK ITEM #85
Description: Tree Sumps 8" diameter by 48" depth;
Qty. 81 x $98.00 Ea= $7,938.00
NET CHANGE PERCOLATION DRAIN INSTALLATION: $7,938.00
Days added for Percolation Drain Installation: 26 Days added
IRRIGATION SYSTEM ADJUSTMENTS
1 ij 1c)
Description of Change: Adjustment in quantities for irrigation material installation is due to value
added changes, added irrigation coverage for trees, and reduction in the number of quick coupler
valves.
Reason for Change: One Additional irrigation valve is added to the irrigation system to cover an
additional zone for irrigation to provide better coverage, additional bubblers are added to trees for
better control of the amount of water applied to tree plantings.
Cost Factor Evaluation: The unit cost for each item adjusted is per the bid unit cost.
INCREASE EXISTING TASK ITEM#59

NET CHANGE IRRIGATION ADJUSTMENTS: $9,919.30
MEDIAN#39 IRRIGATION CONDUITS
Description of Change: An extension to the PVC conduit at median#39 was required due to the fact
that the existing irrigation conduit did not extend beyond installed pavers at the median tip.
Reason for Change: Conduit in medians is required to extend beyond any installed pavers so that the
maintenance contractor can make any necessary repairs to the irrigation line without removing the
pavers.
Cost Factor Evaluation: The cost factor identified as $22.71 per each linear foot for 8 inch material
is found acceptable. The cost factor identified as $7.30 per each linear foot for 4 inch material is found
to be acceptable. The negotiated unit cost identified is added to the bid per the change.

ALTERNATE IRRIGATION SYSTEM INSTALLATION
Description of Change: An alternate irrigation control system was found to be necessary in that the
original specified Motorola Irrigation Control system had been found to not function due to reasons
which are currently under review and are currently being resolved.
Reason for Change: A properly functioning irrigation control system is necessary in order to ensure
plant material health. The non-function of the installed Motorola Control system resulted in the
requirement to install an alternative irrigation control system.
Cost Factor Evaluation: The cost factors involved with this change are for installation cost only.
The cost factors are negotiated unit cost and lump sum. Each item is evaluated in terms of necessary
labor and misc. material required for the installation of the material provided by county.

PLANT MATERIAL ADJUSTMENTS
Description of Change: Certain tree plantings are required to be adjusted due to utility conflicts
found after commencement of construction.
Reason for Change: In coordination with Public Utilities Department the location of existing water
lines were determined in the field and certain trees (Royal Palms)were determined to have root balls
which were too large to be located in the original specified areas. The Royal Palms were removed
from the project in the identified areas and smaller Buccaneer Palms were specified.
Cost Factor Evaluation: The cost factors are based on existing bid unit cost.

PLANT MATERIAL ADJUSTMENTS: $2,492.00
CHANGES TO CRUSHED SHELL INSTALLATION
Description of Change: During construction it was noted that certain median areas were wider than
the original plans had indicated. These areas were determined to require additional crushed shell
material. Also during installation the quantity of stakes for the border of the crushed shell was
increased as a value added item in that the original quantity(in contract)had not been sufficient to
provide for a smooth curve in the border material.
Reason for Change: To provide for additional crushed shell to cover the actual square footage of on-
site conditions. Added quantity of stakes to ensure a smooth curve boarder for all crushed shell areas.
Cost Factor Evaluation: The cost factors are based on existing bid unit cost and negotiated unit cost
to be added to contract.

days added:
INSTALLATION OF DRAIN HOLES TO ENSURE PERCOLATION
Description of Change: The installation of percolation drain holes is necessary to ensure proper percolation in
planted areas. The project specifications called for minimum percolation rate of 2 inches per hour. Onsite
inspection of each hole dug for trees indicated that a percolation hole was required to be dug for 81 tree
plantings. The design consultant in pre-design investigation tested perculation rates and it was discovered that
there may be a need to install perculation drain holes. As a result an alternate was added to the bid for
installation of drain holes at 6' depth. Upon further field investigation after bid award, it was found that a 4'
depth would be sufficient. Negotiations with contractor resulted in a savings of$14,742.00
Reason for Change: It is necessary for the plant health that percolation rate of 2 inches per hour be achieved
at the time of planting of all tree plant materials. Failure to ensure proper percolation rate will result in the
root-ball drowningin the hole it's planted within.
Cost Factor Evaluation: The cost of each percolation drain at $98.00 for a 4 ft. depth (48") and 8 inch
diameter is considered to be acceptable and achieves the desired 2 inch per hour percolation rate. Field
investigations resulted in some modification to the specifications to allow for a reduced depth of installation
for each drain to be 4 ft. versus the original specification of 6 ft. depth. This adjustment resulted in a reduction
in unit cost for percolation drain installation.

ALTERNATE IRRIGATION SYSTEM INSTALLATION
Description of Change: An alternate irrigation control system was found to be necessary in that the original
specified Motorola Irrigation Control system had been found to not function due to reasons which are currently
under review and are currently being resolved. The Alternate Irrigation Control system manufactured by
Hunter Industries was provided to the contractor through a direct purchase order.
Reason for Change: A properly functioning irrigation control system is necessary in order to ensure plant
material health. The non-function of the installed Motorola Control system resulted in the requirement to
install an alternative irrigation control system.

2. Provide detailed rationale for the requested change:
The installation of percolation drain holes is recommended to ensure that a percolation rate of 2 inches
per hour is obtained so that plant material health is not negatively impacted by the existing soil condition.
Percolation drain holes are priced based on actual field conditions. The irrigation system adjustments are
both value added and quantity adjustment based on existing bid unit cost.
Median #39 conduit extension is necessary to ensure that the irrigation system conduit is in place for
future expansion into median #40. The unit cost is negotiated and deemed to be industry standard rates
for this type of installation.
The installation of the alternate irrigation control system was determined to be necessary in that once the
trees were already planted it was found that the Motorola control system did not function. In order to
provide essential water to the planted trees it was necessary to install an alternative irrigation control
system.
Plant material adjustments are related to changes due to utility lines found to be in conflict with proposed
plantings. Staff in coordination with Public Utilities determined that the use of smaller size palm trees
would resolve the noted conflicts.
The change in quantity related to the installation of crushed shell material is determined to be a result of
variations in the actual median widths versus the original data provided for the project. The actual
quantity of material provided is verified by contractor's delivery tickets. Added stakes are valued added
for visual effect in that a smooth line is more desirable than a ridged sharp edge for the borders of
crushed shell areas. The smooth edge could only be achieved with installation of additional stakes
beyond original contract.
3. Provide explanation why change was not anticipated in original scope of work:
The percolation rate of the soil varies and therefore it would be impossible to determine if installation of
percolation drain holes would be required for a given quantity of trees. The project bid did include an
alternate for the drain hole installation and staff negotiated a decrease in price for drain hole installation
based on actual field conditions.
Utility conflicts found would not be known prior to construction as the actual verification of utility location
occurs by the contractor as investigative soft digs are performed. Public Utilities was very helpful in
assisting with verification of utlity line locations and making recommendations for alternative plantings.
Quantity adjustments for crushed shell is related to the actual field conditions which varied from the
Revised 5.16.12
16 JL
original data provided from the roadway engineering project drawings. A re-survey was determined to be
beyond the scope of the original project and not a wise use of the limited funds available for the project.
4. Describe the impact if this change is not processed:
A certain portion of the trees planted would die due to the percolation rate not meeting the horticultural standard of 2
inches per hour. Also, the irrigation system would not function as the alternative control system would not be
installated resulting in cost prohibitive hand watering of all plant materials. There would be conflicts with trees and
the existing water-line found in coordination with Public Utilities. And there would be insufficient quantity of crushed
shell to cover the areas called out for crushed shell due to variations in median width.
