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 3 of 6 — contractor. Any deficiencies or deviations which are observed will be reported to the project team for correction. We estimate a total of 3 site visits will be required to complete the observation of fluid applied vapor barriers and EIFS. Any deficiencies or deviations which are observed will be reported to contractor and/or their subcontractor. Fire Stopping Material Observations We will observe the installation of the fire stopping materials as they are being installed. These observations will be performed by a Staff Engineer on a will -call basis. While on the site, the Engineer will: Observe the installation of the firestop materials along the wall/floor joint, and the wall/ceiling joint. Observe the installation of the mechanical and electrical penetration firestop materials. Compare the products being installed to the details provided by the material supplier. We estimate a total of 4 site visits will be required to complete the fire stopping material observations for this project. Any deficiencies or deviations which are observed will be reported to contractor and/or their subcontractor. Masonry Observations and Testing During construction, AET personnel will perform observations during masonry wall construction, as well as testing of mortar and grout (if required). Our observations and testing will be performed by an experienced Engineering Technician II on a will -call basis, and will include the following services: • Observe that the proper size units are used. • Observe that the units are clean, sound and dry when placed. • Observe that the masonry bearing surfaces are clean. • Observe the placement and alignment of vertical reinforcing bars and dowels, and document that the correct sizes of bars are used. • Observe the placement and alignment of horizontal reinforcing bars, and document that the correct sizes of bars are used. • Observe that the correct lengths of bar lap splices are provided. • Observe that the proper clearance is provided between the bars and the masonry units. • Observe the general construction practices, including compliance with proper cold or hot weather protection as required by the project specifications. Any discrepancies from the project specifications will be brought to the attention of the contractor and/or their subcontractor. Daily field reports of our observations and testing will be available to the contractor and other authorized site personnel. We estimate that our technicians will make 10 site visits to conduct these observations and testing services. While at the site the Engineering Technician II will also sample the mortar and grout. The grout "prism" specimens will be cast for compressive strength testing according to IBC guidelines. One set of four grout
