We have a staff of over 400 engineers, geologists, drillers, field technicians, and support personnel in 13 offices located throughout Florida and Louisiana. We have the resources to complete any project, anywhere, professionally and expeditiously.

Our Tampa Office, the responsible office for this contract, was established in 1986 and is managed by Ms. Whitney Stevens, P.E. She oversees a staff of qualified geotechnical and materials engineers and material testing and inspection technicians who are extremely knowledgeable in soils and material testing, engineering, building inspection, and geo-environmental engineering.

Our Tampa-based field fleet also includes two SPT drill rigs and a dedicated Cone Penetration truck equipped with both a Vertek cone penetrometer and a Vertek seismic cone. We also have a truck-mounted mechanical auger rig.

Our drilling staff, using our in-house drill rigs, will provide drilling and sampling (including rock coring) required under this contract. In addition to the more traditional drill rigs described above, Ardaman has available a narrow gage, track-mounted rig for limited access conditions, and a barge-mounted drilling rig that is well suited for exploration within inland waterways. Ardaman also has the capability to provide a wide range of geophysical testing, including our ground penetrating radar (GPR) team located in Tampa as well as non-destructive pavement testing including Falling Weight Deflectometer (FWD) surveys

As mentioned herein, one of the requirements of this contract deals with performing competent construction materials testing. Ardaman maintains complete construction materials testing and inspection capabilities at our Tampa office. The local facility includes a materials testing laboratory which is inspected and certified annually by the Construction Materials Engineering Council (CMEC) and has the equipment and staff to evaluate the construction materials described in the Scope of Services.

Ardaman is proud of our commitment to maintaining a high degree of technical quality for our field and laboratory equipment and facilities, and our engineering analyses. This commitment is beneficial to all of our clients, but even more so to public clients such as Plant City because of the scrutiny under which Plant City operates. We commit to continually improve and advance our capabilities to maintain the knowledge that will provide the City with positive results.

Ardaman is a large, well established, and financially strong engineering consultant firm. We have been a presence in Florida, and we will maintain that presence for many years to come regardless of the challenges presented by the inevitable economic fluctuations. Plant City can rely on Ardaman to support the City whenever and wherever circumstances require such support.

Past Performance on Similar Projects

Statewide, Ardaman currently holds over 90 continuing services contracts, over 90% of which are with public entities. We understand the particular challenges facing public clients. Public sector assignments comprise a significant portion of our work base. Our relevant experience includes continuing contracts with Pasco County, City of Tampa, City of St. Petersburg, Port Tampa Bay, and Hillsborough County. Our public sector experience has given us the knowledge and ability to manage multiple assignments under a continuing services contract.

Elsewhere in this submittal, we provide detailed descriptions of our performance under these contracts, which are very similar to the Plant City contract.

Staff Experience and Abilities

Much of the strength of Ardaman lies in the people that will be assigned to Plant City. The core of the project team includes individuals who will lead the work under this contract. Their qualifications are summarized below.

Overall Ability Ardaman & Associates, Inc. is one of the largest geotechnical engineering firms in Florida. The company began in Orlando in 1959, and we have operated a local office in Tampa since 1986 and one in Bartow since 1974. This contract's services will originate from the Tampa/Hillsborough County office, supported by the Polk County office in Bartow. Our professional staff is extremely knowledgeable regarding geotechnical engineering, construction materials testing, pavement engineering, and sinkhole engineering.

Consider the following:

Ardaman has served in West Central Florida for 35 years. Our local staff is well acquainted with the subsurface conditions and construction protocols in the area and is exceptionally knowledgeable of Karst conditions and sinkhole issues.

Ardaman holds over 90 continuing services contracts with public entities throughout Florida in general, many of which are in the Tampa / Plant City area, in particular including the following local public entities:

o Hillsborough County o Pinellas County o City of Tampa o City of St. Petersburg o Port Tampa Bay o Hillsborough County Schools o Tampa Electric (TECO) o Polk County o City of Winter Haven o City of Haines City o FDOT District 1

Ardaman's ability to provide quality work according to schedules and budgets has allowed us to receive contract renewals from most of our public clients. By working continuously with public agencies, we have gained a body of knowledge and experience to effectively manage these contracts.

We fully understand that one of the critical elements of our work with Plant City is to effectively serve as your advocates, especially when interacting with the media and public that may impact the technical services, especially a sinkhole occurrence. We will support the City staff and provide accurate and timely information to help you with your obligation to address the public.

Our local offices have many exploratory resources to study subsurface conditions efficiently.

Resources include ground penetrating radar (GPR), a cone penetrometer (CPT), and a Standard Penetration Test (SPT) drilling rig. We also employ a Falling Weight Deflectometer (FWD) for non-destructive pavement studies.

Our field crews are equipped with GPS systems and personal communication devices to locate each individual and dispatch them immediately. Further, the field person can consult with the engineering staff instantly if they encounter changing field conditions. Altering the field program saves time and cost and increases the efficiency of data acquisition.

We have equipped our local Tampa office to provide the full suite of construction materials testing services required in the services' scope. Our local staff includes materials technicians/inspectors and materials engineers. Our local laboratory is inspected and certified annually by the Construction Materials and Engineering Council (CMEC). We equip our field staff with the Meta Field software allowing them to access project data and upload test results from the field through their tablets or smartphones.

Project Approach We will use all our available resources to plan and execute Plant City tasks, employing a three-phase approach to each project.

We will discuss your specific needs and expectations for the project and gather all pertinent information. We will use this information to prepare a detailed scope, fee estimate, and schedule.

We believe that cooperatively developing scopes, budgets, and schedules are imperative to project success.

During the second phase, Ardaman will efficiently plan and execute field and laboratory services and data acquisition. A Florida-licensed Professional Engineer will supervise all services. We will immediately discuss scope changes prompted by field conditions with the City staff.

We will evaluate data, discuss results and options with concerned parties, and document the services in a thorough written report for the final phase.

Regular and effective communications are essential to successful project delivery. Our staff will maintain ongoing information sharing with Plant City, identifying problem issues and resolutions as they occur. The City will always be in the loop.

Key Personnel Ardaman's qualified and committed staff is our most valuable asset. We propose using our team in the Tampa office as principal resources for this contract with our Bartow office support. The following table summarizes these key individuals we will assign.
