Our Understanding of Project Per the Request for Proposal (RFP), we understand that the project will include non-destructive and destructive evaluation of the existing pavement and subgrade of various residential streets in Lake Elmo. The testing is being performed as part of the City's 2014-2016 Capital Improvement Plan (CIP). From our review of the map provided, it appears the streets are residential streets with a bituminous surface. We understand that the requested services include soil borings, Falling Weight Deflectometer(FWD) testing, Ground Penetrating Radar(GPR)testing, and pavement coring. The goals of our testing are to acquire geotechnical and pavement-related information and to evaluate that information relative to the planned improvements. Proposed Scope of Services 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. Geotechnical Exploration Services Site Access,Staking and Utility Clearance Based on the map provided, we assume that all of the desired soil boring areas will be accessible with a truck-mounted drill rig. AA/EOE Providing engineering and environmental solutions since 1957 City of Lake Elmo Proposal SP-13-07579 November 13, 2013 Page 2 We will use GPS to perform and document the staking. Depending on access requirements or potential utility conflicts, our field crew may slightly alter the exploration locations from those proposed to facilitate accessibility. Prior to drilling, we will contact Gopher State One Call and arrange for notification to the appropriate utility vendors to mark and clear the exploration locations of public underground utilities. You or your authorized representatives are responsible to notify us before we begin our work of the presence and location of any underground objects or private utilities that are not the responsibility of public agencies. Standard Penetration Test Borings As identified in the RFP, the following streets/areas have been identified for reconstruction. The requested number of borings for each area is as follows: • Manning Trail North (6 borings) • Eagle Point Boulevard (5 borings) • Kenridge Addition (5 borings) • Kelvin Avenue (4 borings) • 14th Street North (4 borings) • Linden Trail North (4 borings) In all, we will perform a total of twenty-eight (28) standard penetration tests (SPT) borings to a minimum depth of 6 feet below the roadway surface. The thickness of the bituminous surfacing layer and the aggregate base layer (where it can be determined) will be measured and recorded. Penetration tests will be performed and samples will be gathered at 2 1/2-foot vertical intervals. If groundwater is encountered in the boreholes,the depth where it is observed will be recorded on the boring logs. Borehole Abandonment Minnesota Well Code requires sealing of any boring or core that encounters groundwater and is either greater than 25 feet deep or penetrates a confining layer. Based on the intended exploration depths,we do not anticipate the need to seal the boreholes. The boreholes will be backfilled with the auger cuttings and the pavement will be patched. Sample Review and Laboratory Testing Soil samples will be returned to our laboratory and will be visually classified and logged by a geotechnical engineer. To help classify the materials encountered and estimate their engineering properties, we have budgeted to perform 20 moisture content tests and 10 mechanical analyses (through a#200 sieve only). BRAUN NTE RTEC City of Lake Elmo Proposal SP-13-07579 November 13, 2013 Page 3 Pavement Exploration Services As requested in the RFP, we propose to use a combination of Falling Weight Deflectometer(FWD) testing, Ground Penetrating Radar(GPR)testing, and pavement coring. The following areas have been identified for pavement reclamation and are to be included as part of the pavement testing: • Packard Park Neighborhood • Stonegate Phase I Neighborhood • Highlands Trail Falling Weight Deflectometer To help evaluate pavement layer and subgrade conditions,we propose to perform non-destructive Falling Weight Deflectometer(FWD)testing with a Dynatest 8002E model FWD. 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. With known pavement thicknesses and traffic data,the deflection data can be analyzed to estimate spring load capacity(tons per axle), effective subgrade R-value, and effective in-situ granular equivalency(GE). Four impulse loads (two at 6,000 Ibs and two at 9,000 Ibs) will be applied at each test point using a testing interval of approximately 100 feet in a single direction of travel. The roadways will be tested approximately in the outside wheelpath. We expect that this density, which is within typical range for residential/city streets, will be sufficient to capture variation along the roadways. Ground Penetrating Radar To evaluate pavement thicknesses and supplement the FWD data analysis,we propose to complete Ground Penetrating Radar(GPR)testing on the roads with a 2.0-gigahertz, air-coupled unit from GSSI, Inc. Testing will be performed at posted speed limits in a single direction of travel on each road, with pavement thickness data gathered at an interval of approximately one foot. GPS coordinates will be collected during GPR testing and user-marks will identify pavement core locations. 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 To better characterize the in-place pavement and validate the GPR data analysis,we propose to conduct twelve (12) pavement cores to measure the pavement surface. The cores will serve to verify GPR thickness measurements and will be used to visually assess the roadway surface materials as part of our evaluation of pavement reclamation. They will also be available for any additional laboratory testing that may be useful for this purpose. BRAUN NTE RTEC City of Lake Elmo Proposal SP-13-07579 November 13, 2013 Page 4 Traffic Control Based on our review of available MnDOT traffic volume maps, all routes appear to be low volume residential streets. We plan to use traffic signs to protect our field crew and alert motorists of our work during borings, FWD testing and coring. The cost for signs has been included in our estimate. Engineering and Reporting Data obtained from the geotechnical evaluation and pavement testing will be used to evaluate the pavement and subsurface conditions, perform engineering analyses and prepare an engineering report, including: • A CAD sketch showing boring and core locations. • Boring logs describing the materials encountered, including bituminous and aggregate base thickness estimates. The depth to groundwater will be identified if encountered during drilling. • A written summary of the subsurface profile and groundwater conditions. • FWD deflection data and analysis results, including spring load capacity(tons per axle), effective subgrade R-value, and effective in-situ granular equivalency(GE). • Tabular and graphical depiction of the GPR scan results for each of the streets tested. • A discussion of the GPR findings. • Summary of the pavement core results. • Discussion regarding the overall findings for each of the street segments, including a discussion of the proposed improvements based on measured thicknesses and subsurface soil types. The final report will be delivered electronically, unless otherwise requested. Additional Services If borings need to be extended beyond their termination depths, we will charge an additional $15 per lineal foot beyond the originally intended termination depth. Additional site mobilization will be charged at$310 per day. Weather-permitting, hand augers can be performed at a rate of$88 per hour. Depending on the type of reclamation selected for the CIP, Braun Intertec can provide mix design services. The costs associated with this work will be provided upon request. BRAUN NTE RTEC City of Lake Elmo Proposal SP-13-07579 November 13, 2013 Page 5 Cost We will furnish the original scope of services described in this proposal for an estimated fee of $13,957.50. 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 the geotechnical exploration services can begin within approximately two weeks of written authorization and will be completed over a period of approximately two days. For the pavement testing services, we anticipate the GPR and pavement coring will be conducted within one week of authorization. To conduct FWD testing,the subgrade must be free of frost. Once the project is authorized,we will evaluate subgrade conditions and determine if FWD testing is feasible. If it is determined that it is not feasible, FWD testing will be conducted in the spring. We understand that preliminary information is needed as soon as possible so that it can be incorporated into the feasibility study report. This report will be provided to the City in December. We will provide our results as soon as they become available. Depending on the FWD testing, we can provide a draft report that includes all findings, with the exception of the FWD testing. The final report will be delivered once FWD testing is complete. 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. General Remarks Braun Intertec appreciates the opportunity to present this Proposal to you. We are providing it in duplicate so the original can be retained for your records and the copy can be signed and returned to us. Please return the copy 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 significantly delay us beyond our proposed schedule.
