CDM 800 Brickell Avenue, Suite 710 Miami, Florida 33131 tel: 305 372-7171 fax: 305372-9167 HAND DELIVERED September 12, 2005 (Revised October 5,2005) Mr. Hiram Siaba Capital Projects Coordinator City of Miami Beach Capital Improvements Projects Office 1700 Convention Center Drive Miami Beach, FL 33139 Subject: City of Miami Beach Amendment 13A W&WW PS Upgrade Task 2.0 - Shop Drawings and Samples, Factory Witness Testing, Miscellaneous Issues - Additional Services (Amendment 13B) Dear Mr. Siaba, The purpose of this letter is as a follow up to our prior correspondence of March 29th and April 25th to inform you of additional services that CDM has performed during the course of the Construction Services for the Pump Station Upgrades Project. We are requesting an increase in CDM's upper limit budget to cover these additional services. In the meantime, we have utilized the not-to-exceed portion of Amendment 13 A (Task 2.0), which was intended for shop drawing reviews and other miscellaneous unidentified job issues. The four main areas of additional services are associated with the following miscellaneous issues: DERM assistance, structural inspections, pump monitoring and shop drawings. DERM Assistance (Permitting/Accelerated Construction Coordination): In response to a request form the City, CDM has prepared a set of permit applications and drawings for various individual pump stations to meet the permitting requirements of DERM based on a meeting CDM has had with the department. CDM has attended other meetings with DERM and MDW ASD regarding the project with the intent of "fast tracking" the procurement of new construction permits for the project. Other out of scope work included the increased coordination between CIP, the Contractor, CDM, and Public Works for the accelerated construction of Pump Station No.1, which was placed under moratorium by DERM. As you will recall, there was an extensive amount of effort expanded by CDM during the last two weeks of March and early April to get Pump Station No.1 on-line by April 6th. Our cost projections in our earlier letter (dated April 25th) were in-line with the amount incurred. Through the end of July, CDM had spent about $35,220 on the permitting and expediting activities associated with resolving the City's issues with DERM. consulting. engineering. construction. operations KM 1793.1tr.doc CDM Mr. Hiram Siaba September 12,2005 (Revised October 5, 2005) Page 2 Structural Inspections: During the course of recent construction, CDM noticed that the structural columns that support the ground floor above the pump chambers at Pump Stations No.1 and No. 28 showed evidence of fatigue due to corrosion. At the City's request, CDM retained a structural engineering specialist (Dr. Bilgen Erel) to inspect the columns and recommend a method to repair them and return their structural integrity. Additionally, the City has expressed the desire to explore the possibility of converting an existing junction box at the Pump Station No.1 site to a screen chamber. This improvement would help to protect the new pumps from clogging with debris and rags. The chamber will require structural repair from corrosion damage in addition to the structural modifications. Dr. Erel included an evaluation of the structural damage to the junction box at the time he was on-site to inspect the column damage. Dr. Erel inspected the structural component as described in this paragraph and prepare structural contract drawings and specifications for the repairs. The cost of these additional inspections and design is a lump sum $6,950 and is detailed in a letter proposal from Dr. Erel attached to this letter. CDM is requesting a total of $8,000 including our staff time. Pump Monitoring: CDM assisted the City with evaluating an alternative to the SCADA monitoring as described in the original contract documents. CDM assisted with the negotiation of a change order to implement the selected alternative (Nextel radios) and has had numerous correspondences between the City and the Contractor to establish the service in time to be utilized by Pump Station No.1. CDM is requesting a total of $7,000 to cover the costs of investigating and coordinating this issue with the various entities. Shop Drawings: To date, CDM has received, logged-in and processed 366 shop drawings for this project. Due to the unknown quantity of shop drawings the City and CDM agreed to utilize a not-to-exceed contract billed at hourly rates to reduce the project costs. We are asking for an increase of $15,000 to cover the cost of the anticipated remaining shop drawings. We trust that this letter is sufficient to inform you of these additional services and the impact on the current upper limit of $110,940 for the not-to-exceed work. At this time we are asking for an increase in the upper limit cap on this particular task of the project of $65,000 to a total of $175,940. This will take into account the additional items as described and provide for additional unforeseen needs which may arise out of the project. The not-to-exceed (NTE) fee adjustment is summarized as follows: KM1793.1tr.doc COM Mr. HiramSiaba September 12,2005 (Revised October 5, 2005) Page 3 Original Amendment No. 13A (Task 2.0) $110,940 DERM Assistance Structural Inspection Pump Monitoring Shop Drawings Subtotal Increase $35,220 $ 8,000 $ 7,000 $15,000 TOTAL NOT-TO EXCEED BUDGET $ 65,220 $176,160 We trust that this letter will be sufficient for you to authorize the additional funding.

Based on the Contractots latest construction schedule dated July 28, 2005 work on the project is projected to extend until April 12, 2006. The contract between the City and CDM for general services and resident inspection services was intended to run concurrently with the construction contract. Based on the additional time the Contractor is expected to complete the project (approximately 177 calendar days), we request an increase in our contract to extend our services to the new projected completion date as follows: . General Services-The current contact was a lump sum amount of $500,000 for a period of 555 days. This averages $900 per day and was based on an adequate staffing level to cover the anticipated activity level of the Contractor to complete the work in the original time period. Due to the extended period of work our daily activity level is not anticipated to be as much. Therefore we propose a new daily rate of $600 per day for the additional time period. This rate, projected out for the anticipated 177 additional construction days increases our lump sum costs by $106,200. Combined this gives a new total lump sum amount for general services of $606,200. CDM will bill these general services at a rate of $18,310 per month of additional contract time. . Resident Inspection Services-Similarly, the resident inspection services need to be extended. The current contract is not-to-exceed amount of $313,700 for a construction KM 1938.1tr.doc consulting. engineering. construction. operations CDM Mr. Hiram Siaba September 12, 2005 (Revised October 5, 2005) Page 2 period of 510 days. This averages $615 per day and was based on staffing the project with inspectors to cover the anticipated activity to finish the job in the original time period. By stretching the project out over a longer period of time, the activity is not as much as anticipated. Therefore, we propose a rate of $460 per day for the extended period of 177 days. This would raise the upper limit of the not-to-exceed contract to by $81,420 to a new amount of $395,120. This would be billed at our standard billing rates against the new upper limit. The above is summarized on the attached calculation sheet. We trust that this letter is sufficient for you to consider our request for extended construction services.

Based on the Contractor's latest construction schedule dated July 28, 2005 work on the project is projected to extend from a final completion of October 17, 2005 until December 16, 2005. The contract between the City and CDM for general services and resident inspection services was intended to run concurrently with the 480 day construction contract time. Based on the additional time the Contractor is expected to complete the project (approximately 44 calendar days), we request an increase in our contract to extend our services to the new projected completion date as follows: . General Services - The current contact was a lump sum amount of $182,369 for a period of 480 days. This averages $380 per day and was based on an adequate staffing level to cover the anticipated activity level of the Contractor to complete the work in the original time period. Therefore we propose to maintain the rate of $380 per day for the additional time period. This rate, projected out for the anticipated 44 additional construction days increases our lump sum costs by $16,720. Combined this gives a new total lump sum amount for general services of $199,089. We will bill for these services at monthly rate of $11,558 per month. . Resident Inspection Services - Similarly, the resident inspection services need to be extended. The current contract is not-to-exceed amount of $95,250 for a construction period KM194l.1tr.doc consulting. engineering. construction. operations CDM Mr. Hiram Siaba September 12, 2005 (Revised October 5, 2005) Page 2 of 480 days. This averages $198 per day and was based on staffing the project with inspectors at approximately 20 hours a week. We propose to maintain the rate of $198 per day for the extended period of 44 days. This would raise the upper limit of the not-to- exceed contract to by $8,712 to a new amount of $103,962. Services will be billed at our current billing rates up to the new not-to exceed ceiling. . Reimbursables - We have reached the upper limit of the Reimbursables (Task 4.0). We would request that an additional $610 be added to the reimbursables (Task 4.0). This would raise the upper limit to $6,998 or 3.5 percent of the total GS labor. The above is summarized on the attached calculation sheet. We trust that this letter is sufficient for you to consider our request for extended construction services.
