Structural Engineering

Parrish Hansen Structural Engineers is the in-house division of Provost & Pritchard Consulting Group responsible for providing structural engineering services throughout California. Since 1980, Parrish Hansen has specialized in providing structural engineering consulting services to architects, contractors, developers, owners and governmental agencies.

The firm’s experience includes a wide variety of project types including commercial, industrial, governmental, public school, hospital and residential projects involving the use of concrete, masonry, steel and wood materials. Quality of service and expertise in the field of structural engineering, including seismic analyses and damage evaluations, has been responsible for the firm’s excellent reputation in the design and construction industry.

Parrish Hansen’s success is due to a multitude of special skills in their area of expertise, including:

• Code knowledge and interpretive skills: Staff’s knowledge of current codes has been responsible for the firm’s position as “Consultant Plan Checker” and “Consultant Code Interpreter” for the City of Fresno since 1985.
• Complex systems design: Their capability to evaluate complex systems has been responsible for success on many unusual projects, such as the Woodward Park Library in Fresno, CA; Fresno Unified School Districts’ Webster Elementary School expansion; St. Mary’s Church in Sanger, CA and the roof truss system evaluation and remediation for People’s Church, Fresno, CA. In many cases, projects have included extremely unusual and complex entry structures that require significant skill in computer modeling for the determination of cambering of steel and wood structures for deflection control.
• Value engineering: Computer applications abilities have allowed them to establish an excellent reputation with architects and contractors. Evaluation of optional structural systems in the schematic design phase of a project has proven to be a great asset to budget control and structural compatibility with other systems requirements on the project.
• Drawing production: Their capabilities in applying Computer Automated Design/Drafting systems, along with their inter-office development of CADD and REVIT 3-D applications have given them a reputation of producing the highest quality construction documents in the industry. Architects and contractors are consistently commenting on the quality and accuracy of their drawings and how complete and readable they are.

Roof Consulting & Design

T. Brooks & Associates is the in-house division of Provost & Pritchard Consulting Group with more than 50 years of experience as professional roofing consultants.

These have included buildings such as nuclear power plants, utility facilities, schools, hospitals and historic structures as well as industrial, commercial and residential structures.

Roof Consulting services include:

• Roof System Failure Investigations to assist in determining causes of premature roof failure
• Evaluations to assess the current condition of a roof, estimate its remaining serviceable life, and provide a detailed report with photographs of observed conditions and defects
• Development of drawings, specifications and contract documents necessary for reroof projects
• Assessments to determine the best roof option(s) for each building based on a variety of factors
• Quality Assurance Observation during construction phase of Re-Roof Projects
• Preparation of Roof Management Programs to help clients budget and prepare for future reroofs
• Preventive Maintenance Programs to help extend the serviceable life of an existing roof system

GIS

Provost & Pritchard uses geographic information systems (GIS) to integrate different types of spatial data to create useful information for our clients. Our GIS specialists perform analysis and data queries, develop maps and other visualization tools with “intelligent data,” and turn historic data into useful information for modern needs. Information from CAD drawings, global positioning system (GPS) surveys, spreadsheets, aerial photography, and other sources can be combined in GIS for visualization and analysis.

Our staff and clients are using GIS to:

• Create agricultural and municipal facilities maps
• Make informed decisions
• Improve facilities management
• Support environmental documentation
• Centralize information
• Save time and resources

Caves & Tunnels

Provost & Pritchard’s Caves & Tunnels Team offers consultation and engineering services for wine cave, tunnel and alternative underground structure design and construction. Our engineers and geologists have worked on teams with owners, architects, building structural engineers and contractors on more than 350 wine cave and winery building projects in Napa County, Sonoma County, San Luis Obispo County and elsewhere; and have worked with many Irrigation Districts, Water Agencies and Hydroelectric Projects on evaluation of infrastructure, design and construction management of rehabilitation projects, and design and construction of new tunnel projects  over the past 30 years.

Services provided by our Caves and Tunnels Team include:

• Site feasibility
• Consultation and preliminary schematic design
• Site subsurface investigations
• Geostructural engineering
• Design engineering for permiting and construction
• Engineering oversight/construction management during construction

Value Driven Approach

Provost & Pritchard’s typical approach to a cave and tunnel project is to work the project in phases. Our initial consultation phase helps determine the site and project constraints, assists with developing conceptual design of the project, and engages with other consultants on the team or assists with building the client’s team. After our initial phase and development of the project and scope, we provide subsurface investigation and reporting, and design of tunnels and portals in support of permit submittals. Additional work includes engineering services during construction that include performing geologic and engineering observations/tests, materials testing and special inspections during construction , addressing geotechnical/geostructural engineering and design issues during construction, and help the team facilitate a well-constructed project.
