Structural Engineering


The firm provides services covering all phases of structural engineering. These services include studies of structural systems in planning and conceptual design, preliminary design for budgeting, construction documents, and general onsite observation of structural work during construction. The firm has special expertise in wind-tunnel based design of high-rise building structures, including customized site-specific design criteria, having authored the special wind appendix of the Hawaii State Building Code.


Cost Control, Quality of Work and Compliance with Performance Schedule: The firm's design quality control is practiced continuously with direct principal involvement on every project. Project documents of each job are independently reviewed at various key stages throughout the job in order to insure conformance to the highest quality standards. All of the firm's projects are produced on CAD. Fast track projects with tight budget constraints are everyday requirements. Value engineering is implemented from the initiation of conceptual design and is practiced throughout the development of the construction documents to provide a constructible, low cost project meeting the demands of the end users. The firm strongly believes in providing continuity in key personnel throughout a project’s design and construction.
Ability to Perform the Work in the Required Time and Accomplish a Variation of Taskings Simultaneously: Martin & Chock, Inc. has a proven track record in designing large high-quality projects compatible with Pacific construction techniques and economic factors influencing structural materials. At the same time, the conception and execution of structural system designs have consistently utilized leading edge engineering expertise and computer applications. The experienced staff resources of the Martin Associates Group, Inc. numbering over 300 personnel, allows even greater diversity of expertise and flexibility in servicing larger projects with tight schedules.
Building Information Modeling: Implementing BIM into the office, coordinating the BIM model with the architect, and fabricating from the BIM model geometry has many challenges. Marcello Sgambelluri is the BIM Technology Manger for the Martin Associates Group, responsible for the implementation of BIM on numerous large projects in the public and private sectors. We utilize AutoDesk AutoCAD and Revit Structural as well as Rhino and CATIA. It allows us to rotate and explore every detail of a design by expediting the analysis, and testing and modifications early in the design process.
Ability to perform site surveys for detailed evaluations of facilities: As structural engineers, we have performed hundreds of site surveys, more recently in performing structural evaluations and analyses of hurricane shelters and essential facilities. As an example, we collected information from site surveys to create a database of all buildings on University of Hawaii campuses. We surveyed dozens of single wall residences on the Big Island after the Kiholo Bay earthquake, and developed strengthening retrofits applicable statewide. We are presently surveying Hawaii County critical facilities and Maui County Critical Facilities in 2009.
Structural Evaluations/Investigations: Extensive experience in performing structural evaluations/investigations for various purposes: These investigations ranged from narrow focus investigations to comprehensive structural investigations, where field surveys, non-destructive testing of existing materials, and detailed structural analysis of an existing structure have been performed.
  • Seismic and wind load evaluations of all types of existing structures
  • Structural survey and investigation of structures with hurricane damage
  • Post-earthquake structural survey and investigation of buildings and structures
  • Structural survey and investigation of structures with fire damage
  • Structural survey and investigation of structures with flood damage
  • Structural expert witness and forensic consultation
  • Structural survey and investigation of wood framed structures with termite and dry rot damage
  • Due diligence structural surveys and reports for clients purchasing existing buildings
  • Structural investigations of corrosion damage of reinforced concrete structures including alternative repair method
  • Structural investigations involving corrosion of steel-framed structures
  • Investigations of possible structural distress observed by occupants
  • Structural survey and investigation of buildings and structures damaged by foundation differential settlement; expansive soils, and other types of ground movements

Specialized Equipment for Building Investigations: Floor level surveys with hydrostatic meters; Reinforcing bar pachometers for non-invasive investigations; Electrical half-cell potential surveys for corrosion investigation of reinforced concrete.

Capability to use HAZUS-MH or equivalent risk and vulnerability assessment tools such as the Benefit Cost Analysis Tool: Martin & Chock has more experience with the application of HAZUS MH than any other private or public entity in Hawaii, having over 10 years of experience in its use and improvement of the HAZUS dataset for Hawaii. Benefit Cost Analysis is required for any mitigation project grant application per the requirement of 44 CFP § 201.6 (c)(3).All mitigation actions must be prioritized according to a cost-benefit analysis, with a focus on how effective the actions are expected to be with respect to their cost.
Alteration, Renovation, and Retrofit Projects: Martin & Chock, Inc. has extensive recent experience in the alteration, renovation, and retrofit of all types of buildings and structures. These projects have ranged from multi-story hotel and office buildings containing hundreds of thousands of square feet floor area, to two and three story concrete, masonry, steel, and wood-framed schools, apartments, shopping centers, office / administrative buildings, etc.; to single story warehouses, clinics, industrial buildings, and utility buildings containing tens of thousands or just a couple of thousand square feet of floor area. We have also used carbon fiber composite overlays for unique projects involving the repair and retrofit of concrete structural elements.
Corrosion Mitigation: Martin & Chock, Inc. is knowledgeable in techniques for the mitigation of corrosion and repairs of existing buildings, including using cathodic protection techniques.
Seismic Design: Martin & Chock, Inc. personnel have demonstrated capabilities in structural design for all project types and sizes, completed in both the private and public sectors worldwide. Utilizing the latest design techniques, computer applications, and engineering concepts, we create structural systems based on their efficiency and economic feasibility, as well as consistency with each project’s architectural theme. The firm has designed numerous structures in zones of high seismicity, and routinely performs nonlinear, linear, static, and dynamic seismic analyses of complex structures. Gary Chock has structural experience encompassing all seismic zones. Mr. Chock has been active in earthquake engineering through his involvement as founding chairman of the Hawaii State Earthquake Advisory Committee. Mr. Chock represents the Hawaii State Earthquake Advisory Committee at the national Building Seismic Safety Council.
Blast Resistant Design and Anti-Terrorism Force Protection (ATFP): We specialize in design of buildings and other structures to resist the blast forces created by terrorist events or accidental explosions. Our experience in blast effects analysis and design, research and development, testing, and field engineering, will produce an engineering design that will address criteria involved risk factor analysis, damage control, importance factors, and material behavior. We also provide an extensive range of integrity evaluation services for existing facilities. Our sophisticated approaches serve to allow a more efficient distribution of materials, and to maintain strength and structural reliability without undue cost to the project. Mr. Chock is also an approved data custodian under a DD 2345 Militarily Critical Data Agreement, and performs Blast Effect Analysis and ATFP using methodologies of the US Army Corps of Engineers Protective Design Center.
Sustainable Design: Martin & Chock’s contributions to sustainable development as structural engineers include evaluation of:
  • Value engineering to reduce the quantity of structural materials; using less is the best way to minimize environmental impacts.
  • Use of locally available, locally manufactured, and locally extracted resources.
  • Specification of materials employing recycled content such as recycled steel (95% recycled), concrete with recycled (fly ash) pozzolans (25% recycled) to replace conventional cement, thereby reducing CO2 emissions.
  • Coordination of structural specifications with LEED, Green Spec and Whole Building Design Guide, references as well as adjustment of standards to recognize the technical performance characteristics of green materials, such as the unique curing rates of concrete with recycled pozzolans; specification of low VOC products; specification of steel produced in the U.S. with electric arc furnace recycling of scrap steel. Use of sustainable forestry and manufactured wood products.
  • Design to reduce construction waste. For example, we normally detail all concrete stairs to be precasted at the site using the excess concrete usually wasted at the end of a pour. Other secondary structural elements at-grade can be designed to utilize nearly 100% of all batched concrete delivered to the site.
  • Coordination of the structure to enable LEED-rated architectural and mechanical features
  • Collection of supporting documentation and establishing the necessary product data submittal requirements to enable certification of recycled and LEED rating certifications.
