Home My WebLink AboutENGINEERING- FLOOR SUPPORT ANALYSISFDN Engineering, LLC GGANNP-D By �t Date: October 6, 2022 Project: Fitzsimmons Residence Address: 4201 Sunrise Blvd Fort Pierce, FL 34982 Floor Support Analysis - Completion Report This report is prepared for LRE Foundation Repair (contractor) by FDN Engineering (engineer). Floor support jacks (SmartJacks) were installed at the above referenced project. The support system is intended to stabilize and potentially lift the existing floor structure - reducing deflections In the floor and reducing pressure on existing soils. The original design instructed the contractor to install footings, Smartlacks, supplemental support girders and all related components per the support manufacturer's installation instructions and according to their technical specifications, as well as industry standards. See original engineering report for the design and details of the floor support system. See page 2 for the field logs provided by the contractor. See page 3 for a layout of the floor supports as identified by contractor on the field log. The installation of the supports was visually inspected by engineer, and the contractor has supplied engineer a written log of the installed support locations and measured lift. Upon review, the installed support jacks conform to the original design and plans. To the best of my professional knowledge and belief, the design of the floor support system meets the structural requirements of the 2020 Florida Building Code, Seventh Edition to the extent that it applies to our scope of work.

SmartJack Project Assumptions (contractor to confirm assumptions): 1. Structure is two-story, single family residential with wood -frame floors. 2. Soil bearing pressure at the site is a minimum of 2,000 psf. 3. Smartlack model size 288 is specified. 4. Smartlacks and supplemental girders assumed to support interior load -bearing walls or columns. 5. Contractor will install footings, Smartlacks, supplemental girders and all related components per the support manufacturer's installation instructions and according to their technical specs. 6. Contractor to select support base that adequately transfers load from Smardack to soil. 7. Supplemental support girders are restrained against lateral rotation at an interval equal to or less than the Smartlack spacing. 8. Smartlacks supporting existing girders are not spaced farther than the original/existing supports; and the existing girder/joist's condition is adequate to support the new compression load. 9. Supports are not placed on sinkholes. 10. The design assumes the original structure was constructed of conventional means and methods. 11. Where supplemental girders are specified, use S4x7.7 ASTM Gr. 50 (or equal). Smartlack Analysis Notes and Results: 12. Interior floor load is assumed to not exceed 55 psf nominal load (15 psf DL + 40 psf LL), per Code. 13. SmartJacks are designed to support axial compression load only; with a max height of 9'-0". 14. Maximum total load on Smart.lack is 7,700 Ibs. 15. Smardack spacing along the supported girder (or tributary length) shall not exceed 6'-0" O.C.
