Lateral Loads and Expansive Soil Design & Construction

Lateral Loads and Expansive Soil Design & Construction

Edward Fronapfel, Owner of SBSA, Inc. will present on expansive soils and geotechnical considerations in regard to foundation design systems. Discussion topics will include evaluation of geotechnical reports in regard to the requirements of the building codes, determination of the foundation type for serviceability and performance, proper evaluation of on-site soils conditions, and the potential need for reconditioning of the soils to reduce problems associated with the selection of foundation and floor systems.

Evaluation of the lateral and vertical load capacity systems will be included as a necessary means to determine interior framing, façade, and egress issues. Lateral load systems will be examined as they primarily relate to single- and multi-family wood frame structures. An evaluation of the standard of practice versus the standard of care will include the need for a 2-hour firewall design, separation and independence of structures, and veneer applications. Post-tension (PT) design aspects for serviceability and performance criteria will be outlined as an understanding of the needs of the architectural, structural, and MEP systems to handle the expectations of the PT design systems. The instructor will provide an analysis of these systems based on years of forensic evaluation experience and the peer review of current projects. Additionally, the needs of the design, construction, and building officials’ input to properly design, review, and construct these building systems will be considered.

Ed’s experience allows him to see the project in a complete setting and understand the complex interaction between the geotechnical, structural, architectural, and thermal environments. Ed’s civil engineering background includes geohydrology, hydrology, hydraulics, site design, and evaluation of existing structures. Ed’s structural background includes new design and quality assurance of industrial systems, residential, and commercial properties. Post-construction analysis and design to handle issues that came through warranty and/or litigated matters include lateral foundation systems, foundation underpinning, retaining systems, lateral and vertical frame design, building envelope design for both vertical and horizontal applications, HVAC redesign for thermal issues, attic and crawl space ventilation systems, and cold roof/super-insulated roof systems. Ed continues his commitment to the building community teaching and writing for local and national organizations including ASHRAE, ASCE, AEI, BEC, RCI, NAFE, HBA, IBS, CABO, EPA, and others.

Ed’s knowledge gained in working with thousands of common interest properties over the last 30-years for owners, developers, and buyers provides a unique and necessary perspective on the details and decisions that reduce the risk to the property by providing performance and effective life analysis of the products and systems.

SBSA, Inc. President/Owner Edward L. Fronapfel,MSCE, PE, CBIE, D-IBFES, CFCC, EDI, CBCP,F. NAFE, F. ASCE will be speaking Thursday, October 24, 2019 at the ASHRAE Pikes Peak Chapter Meeting discussing the topics of Roofing and Ventilation issues. Roofing complications in Colorado require consideration regarding the code, manufacturer requirements and implications of roofing practices. The long standing code required ventilation of roofs and crawl spaces has been applied without much scientific merit. Mr. Fronapfel will provide a review of the history of the code, the applications of the provisions, and the impact of the installation methods on both new and existing Colorado construction.

ASHRAE, founded in 1894, is a global society advancing human well-being through sustainable technology for the built environment. The Society and its members focus on building systems, energy efficiency, indoor air quality, refrigeration and sustainability within the industry. Through research, standards writing, publishing and continuing education, ASHRAE shapes tomorrow’s built environment today. ASHRAE was formed as the American Society of Heating, Refrigerating and Air-Conditioning Engineers by the merger in 1959 of American Society of Heating and Air-Conditioning Engineers (ASHAE) founded in 1894 and The American Society of Refrigerating Engineers (ASRE) founded in 1904.

In 2012, as part of a rebranding, ASHRAE began doing business as “ASHRAE” vs. using its full legal name of the American Society of Heating, Refrigerating and Air-Conditioning Engineers. Use of ASHRAE reflects the Society’s worldwide membership and that services will continue evolving globally.

The goals and values central to SBSA help us to tackle any challenge and provide a clear path to the completion of a project. Our process, coupled with a strong work ethic, ensures every client a professional and responsive experience from beginning to end. SBSA’s organizational philosophy has fostered numerous long-standing clients and stands as a central pillar of our success.

SBSA’s experience has been gained with Edward L. Fronapfel’s start in the forensic practice of engineering from the mid-1990s.  The team includes engineers, architects and construction professionals with expertise and education in building systems that include the Civil, Structural and Architectural requirements that create the building systems from conception to use.

Our clients include attorneys, insurance companies, builders, developers, homeowner associations (HOA’s), community managers, facility and property managers, buyers, sellers, and owners.

SBSA’s experience allows us to understand how to prioritize the issues, determine the repair and rehabilitation work based on the degree of risks and potential future damages while considering budgetary constraints. Then SBSA will work closely with the owner(s) and repair contractor to get the job done right with thorough repair designs and quality oversight.

Tornado Damage. How to return to Pre-loss condition.

Tornado Damage. How to return to Pre-loss condition.

SBSA can provide professional engineering services to help answer the question, “Where do I go from here?”

SBSA sends out our prayers and thoughts to the victims of the Dallas tornado.  As they restore power, and residents and businesses begin to assess the damages. Understanding the ramifications of the wind induced loads or debris (impact damages) should be done by a team of experts that specializes in building evaluation that includes structural systems, including lateral force resisting systems, and their interrelation to building envelope components.

The assessment of any site should include a well prepared and documented report that includes the necessary repairs to return your property to a pre-loss condition and understanding of the ramifications of the original construction, previous building codes, and new building codes.  When repairing a portion of the structure, the connection of the repaired area to the non-repaired areas requires a proper evaluation to ensure that the systems will function for structural and weather tightness.

SBSA can provide your post loss evaluation and aid in the determination of the actual needs to return your property to a code compliant condition. 

Whether your structure is structurally compromised should include an evaluation that consists of major structural components from foundation to roof, lateral force resisting system, building envelope, fenestrations, and building cladding. 

When evaluating your claim, SBSA will provide timely reports, with clearly written analyses and conclusions that include:

  • Claim review

  • Scope of damages

  • Cause(s) of damages

  • Repair solutions (when requested)

Our experts have conducted hundreds of observations and analyzed many structures due to the impacts of wind, rain, tornados, snow and other weather-related events allowing our expertise to aid you in a determination of the cause and results of your claims.

SBSA Field Testing

SBSA Field Testing

In order to evaluate why your exterior or interior issue occur removal of the veneer must be done.  At some point, a determination of either the commonality of construction or the no commonality can be determined.  From that point, the repair methods can be inferred.  It is never an easy task to provide forensic examination and when proper quality assurance is done you can minimize your damages.
