Our Understanding of Project This project is located on various streets throughout the City of Columbia Heights. The project is broken up into a street rehabilitation project as well as a bituminous surfacing project. The Projects include new granular subbase with geotextile fabric, new aggregate base, new concrete curb and gutter, sidewalk and driveways, spot sidewalk replacement, milling of existing streets and new bituminous surfacing. The project has municipal state aid funding and will follow the SALT Schedule of Materials Control. 1111'11111111!111 !11111 11!111'�; ,• This proposal is based on our review of the documents described below. If the project changes from the information provided in these documents, we may have to submit a revised scope of services and cost. • Project plans and specifications prepared by The City of Columbia Heights dated March 29, 2016. ■ Discussions with you. Project Overview This project is a City of Columbia Heights project with State aid funding. Projects that are constructed with State aid funding are required to perform Quality Control and Quality Assurance (QC /QA) testing in accordance with the Minnesota Department of Transportation's (MnDOT's) SALT Schedule of Materials Control. Personnel with MnDOT certifications must complete the monitoring and testing. Braun Intertec will perform the QA field testing on the project for the items listed in our scope and as shown on our construction materials testing cost estimate. The contractor will be responsible for performing all of the required QC testing and submitting all the documentation upon completion of the project. An audit of AA /EOE INTERTEC City of Columbia Heights Proposal QTB039281 May 20, 2016 Page 3 Concrete The concrete testing for this project will consist of the following: ■ Perform slump, temperature and air content tests on the plastic concrete prior to placement. ■ Cast 4 -inch by 8 -inch cylinders for compressive strength testing. ■ Laboratory compressive strength testing of cylinders. ■ Develop the Weekly Concrete Reports for the Project Engineer's review and their submittal to MnDOT's Concrete Office. ■ Concrete batch plant inspections will be performed by MnDOT Metro Inspections. Bituminous The bituminous testing for this project will consist of the following: ■ Collect one verification sample per mix per day of production. Perform quality assurance tests on these samples which include rice specific gravity, asphalt content, extracted aggregate gradation, gyratory density, coarse aggregate angularity, fine aggregate angularity, and thickness and density of pavement cores. ■ Randomly determine and mark pavement core locations. ■ Observe the contractor coring and core testing in accordance with MnDOT's specifications, which include watching quality control personnel weigh the cores at their laboratory. ■ Bituminous batch plant inspections will be performed by MnDOT Metro Inspections. Reporting and Project Management Test results will be issued for the project as the various tasks are performed. If, at any time, there are failing tests or we observe construction processes which do not appear to be in accordance with the plans and specifications or MnDOT Schedule of Materials Control, we will notify the engineer's representative and any others that we are directed to notify. After the project is completed, we will issue a final report. The report is compiled to meet the requirements for the project audit. The report will include the following: ■ Complete testing roster of Braun Intertec employees conducting testing on this project. ■ Completed MnDOT Materials Certification Exceptions Summary for items tested by Braun Intertec. ■ Completed Preliminary and Final Grading and Base Report. 1:1, -W 1121141,141 City of Columbia Heights Proposal QTB039281 May 20, 2016 Page 5 Additional Services and Overtime It is difficult to estimate all of the services, and the quantity of each service, that will be required for any project. Our services are also directly controlled by the schedule and performance of others. For these reasons, our actual hourly or unit quantities, and associated fees, may vary from those reported herein. If the number of hours or units ultimately required exceed those assumed for purposes of this proposal, they will be invoiced at the hourly or unit rates shown in the attached tabulation. If services are ultimately required that have not been identified or described herein, they will be invoiced in accordance with our current Schedule of Charges. Prior to exceeding our estimated fees, however, we will update you regarding the progress of our work and notify you in the event it appears we will exceed our estimated fees; any fees associated with additional services will be summarized in a Change Order and submitted to you for review and authorization. This proposal was also developed with the understanding that the scope of services defined herein will be required and requested during our normal work hours of 7:00 am to 4:00 pm, Monday through Friday. Services that we are asked to provide to meet the project requirements or a contractor's construction schedule outside our normal work hours will be invoiced using an overtime rate factor. The factor for services provided outside our normal work hours, or on Saturdays, will be 1.25 times the normal hourly rate for the service provided. The factor for services provided on Sundays or Legal holidays will be 1.5 times the normal hourly rate for the service provided. General Remarks Braun Intertec appreciates the opportunity to present this Proposal to you. Please sign and return a 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.
