Based on our discussion and the maps provided, it is our understanding that the City has about 12.5 miles of streets to be evaluated. The streets are located in zones 4 and 5 and are primarily residential in nature with a bituminous surface. The evaluation and testing work is to include pavement condition surface assessments using the PASER rating procedure, pavement coring and hand auger borings, and Ground Penetrating Radar (GPR) testing. Also requested is Falling Weight Deflectometer (FWD) testing on streets within zones 4 and 5 that have been reconstructed or rehabilitated. The purpose of our work is to assist in the City's rehabilitation plans by providing detailed information as it relates to pavement conditions, inplace materials and structural conditions. The following tasks are proposed to help us achieve our stated purpose. If unfavorable or unforeseen conditions are encountered at any point during the completion of these tasks that lead us to recommend an expanded scope of services, we will contact you to discuss those conditions before resuming our work. Visual Pavement Condition Surface Assessment We propose to perform a visual, qualitative rating of each of the streets. Our surface condition assessment will rate each of the streets qualitatively and will follow the PASER rating system developed by the University of Wisconsin. This system has been historically used to assess the City's streets. A ;. City of Columbia Heights Revised Proposal QTB045943 October 7, 2016 Page 2 For each street, we will assign a rating between 1 and 10 for each pre - defined street segment (block), with a 1 representing a failed pavement surface and a 10 representing a new pavement surface. Based on the anticipated findings, we assume the majority of this assessment will be conducted via a walking survey. We will provide some photographs and will note the typical distresses and drainage conditions that we observe. During the visual assessment, we will also note whether or not the roadway crown appears to exceed 2 percent, as well as noting any particular distresses that may be indicative of some sort of structural deficiency. Ground Penetrating Radar (GPR) Testing To provide a continuous profile of pavement layer thicknesses along the streets, we will perform Ground Penetrating Radar (GPR) testing on all streets using a 2.0- gigahertz, air - coupled unit from GSSI, Inc. Testing will be performed at posted speeds in a single direction of travel, with pavement layer thickness data gathered at an interval of approximately one foot. Our GPR measurements will be tied to GPS coordinates and interpreted thicknesses can be verified with information obtained from pavement cores and hand auger borings. A GPR unit of this configuration can be expected to penetrate a maximum of 2 to 3 feet under ideal conditions. Unfavorable soils and ambient and electromagnetic interference can limit the useful depth of the data. Pavement Coring and Hand Auger Boring We propose to perform approximately 20 to 25 pavement cores and hand auger borings. Locations will be randomly selected by Braun intertec and will help characterize the in -place pavement layers and refine the GPR data analysis. Cores will allow us to observe the material conditions, which will help us to further refine our repair recommendations. The depths to which the hand auger borings are performed is expected to vary, but we intend to extend them two to three inches into the subgrade material. The cores will be submitted to our lab for total thickness measurements and will be examined for any material deficiencies. The cores will be retained for any additional laboratory testing that may be useful. We have assumed 15 hours for the coring and hand auger borings and will repair the core holes with a cold -mix bituminous patch. Failing Weight Deflectometer (FWD) 'testing According to the maintenance map provided, about 5.6 miles of streets in zones 4 and 5 have recently been reconstructed or rehabilitated. On these streets, we will perform non - destructive FWD testing with a Dynatest 8002E model FWD. Depending on the observations made during the visual condition assessment, we will also provide recommendations for the testing of any additional streets that appear to have structural issues. The FWD is a non - destructive testing device specifically designed for evaluating pavements and operates by measuring pavement surface deflections from an applied wheel- simulating impulse load. Four impulse loads (two at 6,000 Ibs and two at 9,000 ibs) will be applied at each test point. We will perform the FWD testing in a single direction of travel, at a rate of one test per 100 feet. City of Columbia Heights Revised Proposal QTB045943 October 7, 2016 Page 3 Deflection data will be utilized to estimate effective R- values, pavement structural capacity, effective GE, and required 10 -ton overlay thickness. Analysis and Reporting Data obtained from our work will be used to prepare a draft report including: ■ A CAD sketch showing project area and exploration locations. ■ Scaled ratings for each of the evaluated street segments. This will be provided in both spreadsheet format and within the written report. ■ A summary of the general observations related to potential problems that affect pavement performance, such as noting certain frequent distresses or apparent drainage issues. ■ Results of GPR testing for each of the evaluated streets. • Summary of pavement core and hand auger boring results. • For streets recently reconstructed or rehabilitated, FWD deflection data and analysis results, including spring load capacity (tons per axle); subgrade R- value; granular equivalency (GE); and 10 -ton overlay thickness. • Discussion regarding the overall condition for each of the street segments and recommended repairs given the results of our evaluation and testing. Once the draft report has been prepared, we will meet with the City to discuss the preliminary findings. Any comments will then be included in the final report. Our final report will be submitted electronically, unless otherwise requested. Cost We will furnish the services described in this proposal for an estimated fee of $14,960. A tabulation showing hourly and/or unit rates associated with our proposed scope of services is attached. Our work may extend over several invoicing periods. As such, for work that is performed during the course of each invoicing period, we will submit partial progress invoices. Schedule We anticipate that the pavement surface evaluation work can begin within approximately two weeks of authorization; the evaluation will take approximately 3 days to complete. Fallowing the surface assessment, we will perform subsequent testing as weather conditions allow. Depending on conditions, some testing may be performed in the spring of 2017. We anticipate our final report will be provided in May of 2017. { r City of Columbia Heights Revised Proposal QTB045943 October 7, 2016 Page 4 If our proposed scope of services cannot be completed according to this schedule due to circumstances beyond our control, we may need to revise this proposal prior to completing the remaining tasks. We will be happy to meet with you to discuss our proposed scope of services further and clarify the various scope components. We appreciate the opportunity to present this proposal to you. Please sign and return a copy to us in its entirety. The proposed fee is based on the scope of services described and the assumptions that our services will be authorized within 30 days and that others will not delay us beyond our proposed schedule.
