Agenda 05/13/2013 Item #16D125/14/2013 16.D.12. EXECUTIVE SUMMARY Recommendation to approve Change Order #5 in the amount of $26,991.55 and a time extension to Contract #12 -5878, Radio Road East MSTU Landscape & Irrigation Project, for Hannula Landscape and Irrigation, Inc., and approve the required budget amendment. OBJECTIVE: To complete the installation of landscape and irrigation in medians on Radio Road East and to amend the budget. CONSIDERATIONS: On May 22, 2012, the Board awarded Contract 12 -5878 to Hannula Landscape and Irrigation, Inc. ( "Hannula "), in the amount of $467,914.63. Since the commencement of construction, on July 18, 2012, there have been four (4) previous changes to Contract 12 -5878, which has added 301 days to the contract and $36,452.70 (7.79 %) making the revised contract total $504,367.33. The Board's Approval of Change Order 95 is necessary because the total cumulative change is 13.56% and the Purchasing Policy mandates that the Board approve any change order over 10 %. Change order #5 adds an alternative irrigation system for watering plant materials — because the original specified Motorola irrigation controller is non - functional. Staff is currently working with Motorola Corporation to resolve the issues related to the operation of the controller; however, there is an immediate need to provide water for the project using an alternative irrigation system controller (manufactured by Hunter Industries) so that the plant materials installed do not die from lack of water. The labor for installation of the alternative irrigation controller, at a cost of $1,759.00, is per- negotiated unit pricing with the contractor; and materials supplied by the county through direct purchase, in order to avoid contractor mark -up. In the absence of the alternative irrigation control system the cost for hand - watering the project is estimated at $368.00 per day, or approximately $8,000 for one month (the plant materials require almost daily watering upon initial planting). To avoid this excessive cost, the project manager is directing Hannula to install the alternative irrigation control system so the project is irrigated without the need for costly hand - watering. Also included in this Change Order is the installation of percolation drain holes to allow water to drain at the minimum specification rate of 2 inches per hour and prevent water from being trapped in the holes dug for trees. Each hole dug was tested to ensure that they met the percolation specifications. Prior to bid award it was known that drain holes may be necessary and an alternate was included and quoted at $280 each for a 6 ft. deep drain hole. Through on -site investigation and negotiation with the contractor the specification recommended for modification to 4 ft. depth for each drain hole at a rate of $98.00 per hole. There were a total of 81 drain holes required for the project so with the modification of depth and cost reduction per hole the increase was $7,938.00 (a savings of $14,742.00 below the quoted cost for 6 ft. deep hole). Approval of this Change Order will further increase the cost of the project by $26,991.55 and add an additional 46 calendar days to the project. Summary of Changes: 1. Percolation Drain Hole installation: Reason for this change is to ensure that percolation rate of 2 inches per hour is achieved for all tree plantings. Unit cost is negotiated based on modified specification for 4 ft. dept rather than 6 ft. depth. If change is not done trees will drown in holes in which they are planted due to soil conditions not allowing proper percolation. Net Change: $7,938.00. Net days added: 26 Days 2. Irrigation System quantity adjustments: Change is necessary in order to make necessary field adjustments to quantities of existing bid line items using unit cost identified in the bid. If change is not done the quantities of material would not be sufficient to match actual field conditions. Net Change: $9,919.30 Net days added: 0 Days (zero days) Packet Page -3281- 5/14/2013 16.D.12. 3. Median 439 irrigation conduit extension: The conduits found as installed by others uurmg ine roadway construction were found to be too short in that they did not extend beyond the pavers installed at the end of the median 439. If this change is not done the conduit would not allow for continuation of the irrigation system into adjoining median #40. Net Change: $450.15 Net days added: 0 Days (zero days) 4. Installation of alternate irrigation control system: The alternate irrigation control system is necessary in order to provide for watering of plant materials without manual hand watering. The cost of hand watering was found to outweigh the cost for installation of an alternative control system. The cost associated is a negotiated labor cost per each item provided by the county for installation by Hannula Landscape. Net Change: $1,759.00 Net days added: 20 Days 5. Plant material adjustments: There was discovered certain utility conflicts which required swapping out large Royal Palm trees to smaller Buccaneer Palms near existing water - lines. If change is not done the original Royal Palm planting would potentially damage the water -line. Net Change: $2,492.00 Net days added: 0 Days (zero days) 6. Crushed shell installation: During construction it was noted by the contractor that certain portions of the medians measured to be a greater distance from curb -to -curb. This variance in the actual field conditions versus original plans which were based on original roadway engineering survey resulted in an additional quantity of crushed shell being used to cover the planting beds and also additional stakes to implement the design. If this change is not done there would not be sufficient quantity of crushed shell to cover planting beds. Cost factors are based on bid unit cost and negotiated unit cost for additional stakes. Net Change: $2,639.10 Net days added: 0 Days'(zero days) 7. Contractor's Bond Increase: Adjustment of the contractors bonding is necessary to comply with terms of contract bonding requirements. Bond increase is evaluated in terms of Lump Sum in terms of a percentage of the overall project value. Net Change: $594.00 Net days added: n/a 8. Maintenance of Traffic (MOT) Increase: Adjustment of the contractors bonding maintenance of traffic for the added 46 days per this change proposal is necessary to provide for maintenance of traffic throughout the duration of the project. The cost associated with the increase is evaluated in terms of the provision of MOT on a daily basis for an additional 46 calendar days. Net Chanae: $1,200.00 Net days added: n/a FISCAL IMPACT: At the end of FY 2012 unexpended funds for the Radio Road East MSTU Landscape project, in the amount of $67,600, were swept into Fund (166) carry - forward. Funds for the requested change order are not presently budgeted but are available within Fund (166) carryforward. The required budget amendment will appropriate carry forward in the amount of $67,600, increase the project budget by $41,600 and place the balance of $10,900 in reserves. LEGAL CONSIDERATIONS: This item has been reviewed and approved by the County Attorney's Office, is legally sufficient for Board action and only requires a majority vote for approval —SRT. GROWTH MANAGEMENT IMPACT: There is no growth management impact associated with this Executive Summary. RECOMMENDATION: That the Board of County Commissioners approve Change Order 45 to Contract #12 -5878 for Hannula Landscape and Irrigation, Inc., in the amount of $26,991.55, authorize a time extension of 46 additional calendar days and approve the required budget amendment.

CONTRACT NO. 12 -5878 BCC Date: .4/z 2 210/;L- Agenda Item: // & PROJECT NAME: Radio Road East MSTU Landscape & Irrigation Proiect PROJECT NO.: PO 450 0136845 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 Ge' Packet Page -3285- 5/14/2013 16.D.12. 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.

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.

Days added for Alternate Irrigation Control System Installation: 20 days added 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 Imes 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.

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.

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 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.

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 fora 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. stments for crushed shell is related to the actual field conditions which varied from the Revised 5..16.12 Packet Page -3295- original data provided from the roadway engineering project drawings.

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. "y3e.f4Cbai�ge•Allcificaton Cbangerggest+d . ; 1.
