TESTING, *MATERIALS 'FORENSICS November 13, 2013 City of Lake Elmo Department of Public Works 3800 Laverne Avenue North Lake Elmo,MN 55042 Attn: Ryan W. Stempski, PE RE: Proposal for Geotechnical Services 2014-2016 Street Improvements, Lake Elmo, Minnesota Dear Mr. Stempski: Per your November 11 request, we are submitting this proposal to conduct the following scope: "Reconstruction"Area Scope: Fieldwork • Drill and sample 28 standard penetration test borings to depths of 6 feet on the existing streets (six separate street segments). • Clear underground public utilities through the Gopher State One Call system. • Measure in-place bituminous and apparent aggregate base thicknesses. • Measure and document the boring locations.No measuring of the surface elevations is planned. Laboratory • Classify the soils per the Unified Soil Classification System(USCS). • Conduct water content tests on cohesive samples retrieved. • Conduct unit price soil index testing ($570 unit price budget, allowing for six sieve analysis tests). Report • Logs of the test borings, including pavement thicknesses and lab test results. • Descriptions of the drilling, sampling,testing, and classification methods. • Review of soil and ground-water conditions encountered. • Geotechnical opinions/recommendations pertaining to the planned street improvements including estimate of subgrade R-value. The scope of work defined in this proposal is intended for geotechnical purposes only, and not to explore for the presence or extent of environmental contamination at the site. However, we will note obvious contamination encountered. 550 Cleveland Avenue North I St. Paul, MN 55114 Phone 651-659-9001 I Toll Free 800-972-6364I Fax 651-659-1379I www.amengtest.com I AA/EEO This document shall not be reproduced,except in full,without written approval from American Engineering Testing,Inc. City of Lake Elmo November 13, 2013 Page 2 of 3 "Reclaim" Area Scope: Fieldwork • Perform Falling Weight Deflectometer(FWD)testing. The FWD testing will be done using the standard Strategic Highway Research Program(SHRP) sensor spacing and will be done at 6,000 and 9,000 lbs. force. The testing will be performed at an approximate 500 foot spacing in each of the driving lanes producing an effective 250 foot spacing along the roadway alignment. We expect this will total about 60 test locations. • Perform Ground Penetration Radar(GPR)testing. The GPR testing will be done at a 1- foot spacing in each of the driving lanes. We expect this will total about 6 lane miles. • Conduct pavement cores and aggregate base thickness exploration at 8 locations to correlate GPR thickness data to actual measurements. Report • Analyze FWD data for load capacity of the roadway, stiffness, and required reclaim/overlay thickness. • Prepare a report showing the spring load carrying capacity, effective granular equivalency, and effect subgrade R-value; and recommendations for the street improvements. Fee: Our services will be performed on a time-and-materials basis per the attached fee schedule. For the scope described, we will establish $10,500 as a not-to-exceed fee ($7,150 estimated for the "reconstruction" portion and $3,350 estimated for the "reclaim" portion). In the event the scope of our work needs to be revised, we will review such scope adjustments and the associated fees with you, and receive your approval before proceeding. Schedule: Based on our current backlog, we anticipate the following schedule (following authorization to proceed): • Soil borings-begin within two weeks,three days of drilling expected • FWD/GPR/coring-within about one week • Report-within about one month. Terms/Conditions: Our services will be performed per the Contract Agreement Between the City of Lake Elmo and American Engineering Testing, Inc.for Professional Services, dated July 20, 2010. Acceptance: Please indicate your acceptance of this proposal by endorsing the enclosed copy and returning it to us. The original proposal is intended for your records.
