Mr. Muna Weragoda, P .E. . . . via e-mail (aweagoda@ircgov. com) Project Engineer Subject . En.fineering Testing Services 12t Street and 27th Avenue Improvements — IRC Project #9334 Indian River County, Florida Dear Mr. Weragoda: INTRODUCTION As requested, Dunkelberger Engineering & Testing, Inc. (Dunkelberger) is pleased to submit this proposal for Engineering Testing Services during construction activities at the subject project in Vero Beach (Indian River County), Florida. PROJECT INFORMATION The project involves drainage and roadway improvements to approximately 'h mile of 12th Street starting about 250 feet east of 32'd Avenue through the intersection at 27th Avenue to about 400 feet east of 25th Avenue . The proposed drainage improvements primarily involve the installation of about 2,400 lineal feet (If) of 60-inch diameter reinforced concrete pipe (RCP) and 1 ,781 if of 8-inch diameter Type II underdrain. Associated with the primary drainage trunk line will be secondary drainage consisting of 124nch, 15-inch and 184nch diameter RCP. The roadway improvements will include new construction (road widening) and asphalt milling. In addition, there will be concrete headwalls, sidewalks and driveway construction. Also, a traffic signal mast arm will be installed at the intersection of 12th Street and 27th Avenue. The scope of work described in this proposal is based on our review of the construction drawings prepared by Indian River County — Engineering Division, dated May 25 , 2012, and our experience with similar projects for you in the past. SCOPE OF SERVICES We will provide the required construction materials testing services for the project. The specific scope of our services will include the following. State of Florida Board of Professional Engineers Authorization No. 6870 Toll Free (877) 643. 6832 12th Street and 27th Avenue Improvements Page 2 Project No . PSL-09-3054 ( 10 . 7) April 12, 2013 Field Observation & Testing • Earthwork observations by an engineering technician during the site grading operation including the proof-rolling of "strip grade" for the roadway widening alignment and embankment construction as requested by Indian River County. • In-place density testing will be performed during placement of the embankment fill for roadway widening. The density tests will be performed at a frequency of approximately one ( 1 ) test for every 200 lineal feet of roadway/embankment within the proposed alignment, for each 1400t thickness of backfill placed. • In-place density testing during backfilling of storm drains and catch basins for each 1 -foot lift of backfill placed from the bottom of the structure up to an elevation corresponding to final grade. • In-place density testing during backfilling of the rigid and flexible pipelines. Below pavement areas, density tests will .be performed at a frequency of approximately one test location for each 2001f (or fraction thereof) of pipe . At each roadway or driveway crossing, density tests will be performed for each 6-inch lift of backfill placed starting at an elevation corresponding to the invert of the pipe and extending up to the final grade. • In-place density tests within the stabilized subgrade and base course layers at a frequency of approximately one ( 1 ) test for each 2001f of roadway. At roadway crossings for the pavement restoration, 24-inches of base rock will be placed and tested in four (4) &inch lifts . • In-place density tests for the sidewalk and driveway subgrade prior to concrete placement. • Sampling, slump testing , molding, transporting, curing, and laboratory testing to determine the compressive strength of concrete used for the sidewalk, driveways and curbing. Laboratorp Testin • Perform laboratory moisture-density relationship (Proctor) tests (AASHTO T- 180 and AASHTO T-99) and sieve analysis (percent fines for soil classification purposes) tests on the embankment fill and/or pipe backfill soils . • Limerock Bearing Ratio (LBR) tests for stabilized subgrade and base course within the roadways . • Concrete cylinder test specimens will be tested following ASTM C39 for their compressive strength at 7 days and 28 days after placement. Engineering & Reporting • Engineering oversight during the construction to coordinate the aforementioned test program, make site visits, attend progress meetings, and provide professional engineering consultation, as needed. • Submittal of brief engineering reports documenting our findings and test results. DUNKELBERGER 120' Street and 27`I' Avenue Improvements Page 3 Project No . PSL-09-3054 ( 10 . 7) April 12, 2013 Our construction materials testing services will be provided on an as-needed basis as dictated by the pace and methods of construction . For scheduling purposes, we normally request at least 24 hours notice prior to the time the field services are needed. TERMS AND PAYMENT We propose to bill this work on a unit rate basis in accordance with our current 2013-2014 Continuing Geotechnical Services Agreement. Based on the described scope of work and testing frequencies, we have provided an Estimated Scope and Budget (Attachment A) for the required services and established a budget of $2.1,470. 00.
