City of Elk River — Elk River Fire Station 93 .A MERICAN Proposal for Project Testing Services j ENGINEERING AET Proposal No. 26-20557 March 30, 2021 TESTING, INC. Page 2 of 6 — Soil Observations and Testing for Building and Pavement Sub2rades: • Observations of building and pavement excavations and subgrade soils (by Senior Engineering Assistant). • Document elevations at the bottoms of the excavations and judge adequacy of excavation lateral oversizing. • Perform shallow hand auger borings and hand cone penetrometer probes to evaluate the soils in the observed excavations. • Observations of subgrade soils during test roll procedures (by Senior Engineering Assistant). • Soil compaction tests in building and utility excavations, pavement subgrade soils (by an Engineering Technician I). • Standard Proctor tests of each different type of soil or Class 5 aggregate base encountered at our test locations. • Sieve tests of granular fill and Class 5 aggregate base materials if requested. Post- Installed Anchor Observations During installation of the post installed adhesive anchors, personnel from AET will observe the location, placement of the anchors. While at the site, the AET personnel will perform the following services: • Review the most recent plans and specifications available at the jobsite. • Observe that the correct number, size, and type of anchor were installed. • Document the specified adhesive was used and that the adhesive is not expired. • Observe that the specified cleanout procedures were followed. We estimate that our Staff Engineer I will make 2 site visits to conduct these observations and testing services. Reinforcing Steel Observations and Concrete Testing: • Observations of reinforcing steel in the concrete building elements to evaluate conformance to approved structural drawings (by an Engineering Technician II). • Field testing of concrete placed for the structural elements and other concrete features: including slump tests, air content tests, and temperature tests (by an Engineering Technician I or II). • Project specifications require that two sets of cylinders be cast in the first 25 cubic yards then every 50 cubic yards (or fraction thereof) of each type of concrete placed each day. Each set will consist of (2) sets of three cylinders; two which will be tested after 7 days and two which will be tested after 28 days. • Pick up cylinders from the jobsite for delivery to AET laboratory. • Compressive strength testing of concrete test cylinders (I test at 7 days; 2 tests at 28 days). Observation of Fluid Applied Vapor Barrier & EIFS AET has included observations of the fluid applied vapor barrier and EIFS to the exterior CMU walls in our fee estimate. These services will be performed by a Staff Engineer I on a will -call basis when requested by the
