EXHIBIT B – SCOPE OF WORK 
 
Building and Safey Services 
Since 1979, Willdan’s Building Safety Group has provided building plan review and inspections for public 
jurisdictions throughout the western United States. Willdan’s experience and strength in building safety 
encompasses a complete range of technical disciplines, including permit issuance; building, flood zone, 
and fire-life safety plan reviews and inspections; grading inspections, and accessibility inspections. 
Willdan provides these services through an experienced, qualified staff that will respond to the needs of 
the County. Willdan's proposed team is unique in its blend of knowledge of and experience with: 
 
• 
County of Maricopa procedures, processes, standards, codes, guidelines, and regulations 
through services provided to municipalities within the County 
• 
Other applicable jurisdictional codes, guidelines, and regulations 
• 
Project construction 
 
Through active participation in the International Code Council and other building safety organizations, 
we maintain our training and understanding of the latest industry trends, alternative building materials, 
green building principles, and sustainable construction. Our personnel possess registrations and 
certifications in civil, structural, architectural, life safety, electrical, plumbing, and mechanical disciplines 
and are experienced in reviewing and inspecting both simple and complex projects, including accessibility 
compliance and fire protection engineering. 
The knowledge and experience of our staff have allowed Willdan to provide services from startup of 
building safety operations for newly incorporated cities to full department staffing to every day on-call 
inspections and plan reviews for residential and small commercial facilities, subdivisions, and right-of-way 
improvements to the specialized inspection of educational facilities, high rises, commercial buildings, 
hotels, casinos, and power plants. 
 
Building Plan Review Expertise 
Because of our hands-on approach to solving code issues, we have typically worked with paper plans. 
When plans 
are received in a printed format, Willdan has fully developed procedures that produce timely and accurate 
plan reviews. We utilize our proprietary software, Plan Check Tracking System (PCTS) to log and track 
plan reviews throughout the project life. 
 
While hard-copy plan reviews have been the traditional method, to alleviate delays and costs incurred 
while transmitting hard-copy plan reviews and comments, Willdan offers our clients state-of-art electronic 
plan reviews. A few advantages of our tree-saving electronic plan review process include: 
 
• 
Immediate input and feedback through on-line collaboration 
• 
Time savings – no waiting for emails or mail to be delivered 
• 
Cost savings – no printing or overnight delivery 
• 
No additional hardware or software – only Internet connection necessary 
 
Electronic plan review services are provided – at no additional cost – at the request of the applicant or the 
agency we serve. Submittals are accepted in PDF format. 
 
Access to our electronic plan review files is set up through a secured portal. Willdan establishes user 
profiles to provide defined access such as view only, read and comment, or full access for comment 
coordination and review. Electronic redlined plans are transmitted back to the design team or the County 
as directed. This service allows for on-line collaboration between the County, designer, and plans 
examiner to facilitate a complete understanding of plan review comments and reduces shipping, printing, 
and timelines for plan review processing for the applicant. 
When reviews are completed and the project is approved, the electronic files are transmitted to the 
County in a 
format compatible with the County's recordkeeping media. 
 
Building Inspection and Code Compliance Expertise 
Willdan provides dedicated inspectors and backup inspectors for our clients' building safety needs. Our 
experienced staff has inspected major projects that include casinos, low- and high-rise hotels and offices,

SERIAL 230191-RFP 
 
parking structures, retail commercial developments, shopping centers, condominiums, regional malls, and 
major residential developments. 
Our inspectors are ICC certified and fully experienced to perform residential, commercial, and industrial 
inspections for compliance to the approved plans and related documents. The inspections will be 
performed in accordance with the County’s adopted version of the International Building Code, 
International Residential Code, International Mechanical Code, International Plumbing Code, National 
Electrical Code, and the County and Federal regulations for Accessibility, International energy Code and 
International Fire Code and provisions of NFPA. 
 
Inspection staff will be available to meet with County staff, builders, developers, and citizens to provide 
assistance and resolve any inspection issues that may arise. Inspectors shall attend and participate in 
required meetings with other County inspection and plan review staff, property owners, contractors and/or 
design professionals. Inspectors will review the permit package to verify that the on-site condition is 
consistent with the appropriate records for square footage, setbacks, heights, and other requirements that 
may be applicable. Inspectors will comply with the County’s procedures for reporting inspection results, 
use County inspection correction forms, make appropriate entries onto the permit documents, and follow 
County procedures prior to finalizing a building permit. 
 
Willdan will verify that all inspection records, including daily records of what was inspected which will be 
recorded on the job card, and permit copy entered into the County’s Building and Safety computer 
system. We will employ such techniques as necessary to minimize delays to builders and provide helpful 
advice and counsel to builders, 
owners, engineers, and architects as to enhance the orderly flow of the construction process yet 
maintaining an 
effective level of enforcement. Inspectors shall ensure that any construction changes are documented 
and approved by appropriate County staff. Our inspection staff are supplied with cell phones and laptops 
and/or iPads for email communication and document creation and record keeping. Inspections will be 
provided the next working day following a request made by 4:00pm the previous day. 
 
Civil Engineering, Water, and Wastewater Servies 
Willdan is fully staffed and equipped to provide plan re-views for all development aspects of a project from 
planning through engineering and building safety. We offer a full complement of development plan review 
services for public infrastructure, private development, or third‐party reviews. Willdan provides a varied 
array of civil engineering design reviews, including residential, industrial, and commercial developments; 
recreational facilities; public buildings; site grading; landscaping; transportation-related improvements; 
and water, wastewater, storm drain, and flood control facilities. 
 
Willdan's plan reviewers possess improvement plan review capabilities in street, sewer, water, traffic, 
street lighting, striping, erosion control, and drainage. Hydrology and hydraulic calculations for off‐site 
improvements are reviewed for accuracy to verify that drainage plans are adequate for design runoff. 
Drainage plans and hydrology calculations are coordinated with the regional flood control agency, where 
necessary. Structural calculations, when submitted, are reviewed by our in-house structural engineers. 
 
Grading plans are reviewed against geotechnical recommendations. Sewer, water, and other utility offsite 
improvement plans pre-pared for other agencies are reviewed for conflict/consistency with established 
design guidelines. Our plan review services involve review of planning, civil, and site plans submitted for 
improvements in conjunction with land development applications. The plans will be subject to a thorough 
review to ensure facilities satisfy adopted standards and that sound planning, engineering, and 
construction practices are observed. Improvement plan reviews include, at a minimum, grading, erosion 
control, street, sewer, water, street lighting, and drainage plans. Willdan will review supplementary plans 
and calculations, including hydrology and hydraulic plans and calculations, sanitary sewer plans and 
calculations, traffic studies, soils reports, and structural calculations as may be required. In conjunction 
with the plan review, the bond estimate for improvements will be verified. 
 
Optional Available Services 
 
Accelerated Plan Review 
The accelerated plan review process provides some applicants the opportunity to pay a premium for their 
plan review to reduce the review time to half or even one-quarter of the standard review time and,

SERIAL 230191-RFP 
 
ultimately, reduce some carrying costs of a development project. This process is highly customer-service-
oriented and is extremely beneficial to the applicant as well as to our clients. 
 
Third-Party Agreements 
Third-party agreements can be utilized by the County to allow the permit applicant/holder to pay Willdan 
directly for the same services that the County offers throughout-sourced plan reviews or inspections. The 
advantage of this 
process is that it allows the County to reduce revenue and expenditure concerns, while maintaining 
control over the plan review and inspection process. 
 
Project Approach 
Willdan sees our role as that of facilitator and guide—helping development applicants get through the 
review, permitting, and inspection processes – rather than leaving the applicant in a lurch. We understand 
that the process of complying with ever-changing codes, standards, regulations, and laws can be a 
formidable and daunting undertaking for even the most seasoned design or construction professional. 
Furthermore, an understanding of the complexities associated with processing private development 
applications and potential competing interests is essential to exceptional customer service. We are there 
to serve the bests interests of our client and assist developers and designers to complete their desired 
projects for the betterment of the entire community. Common sense decision-making and technical 
analysis in interpreting the intent of regulatory guidelines are significant strengths Willdan's staff brings to 
the County. 
 
Plan Review Services 
All building plans are examined for compliance with adopt-ed version of the International Building 
Code, International Residential Code, International Energy Conservation Code, International 
Mechanical Code, International Plumbing Code, National Electrical Code, International Existing 
Building Code, International Property Maintenance Code, International Fire Code, ADA Accessibility 
Code, and all applicable County ordinances. Plan reviews for disabled access compliance may include a 
review of precise grading plans. Plan reviews include an overview of the application package for other 
applicable requirements, such as approvals from other local agencies and districts and coordination with 
other County departments. All plan reviews comply with the County’s directives, codes, and policies as 
determined by adopted building codes and state and federal standards and involve a review of design 
element requirements for: 
 
• 
Architectural 
• 
Plumbing 
• 
Structural 
• 
Electrical 
• 
Disabled Access 
• 
Fire 
• 
Life-safety 
• 
Mechanical 
• 
Residential 
• 
Energy Conservation 
 
Typically, when a project is received, it is logged into PCTS to allow internal tracking of the project. Based 
upon the type of review needed, Willdan’s project manager will triage the project and assign it for review. 
The triage process ensures that the disciplines needed are identified and the appropriate staff is 
assigned. Through PCTS, the project is separated into segments allowing each discipline to complete 
their portion in a manner that fosters easy compilation of all review comments by the project manager. 
During the review cycle, the project manager reviews the schedule to determine the status of the project. 
PCTS identifies the timeline status of each discipline in the review process. The system points out 
potential re-source overload and bottlenecks – allowing our project manager to assess the review 
schedule and bring in additional corporate-wide staffing resources if needed.  
 
Following the hard-copy or electronic review, senior staff members certified or registered in the given 
discipline perform a quality assurance overview to confirm a complete and accurate review has been 
performed. If issues arise, the senior staff will meet with the plan reviewer to discuss the discrepancy and 
add or subtract comments in the correspondence prior to returning the project to Maricopa County. We

SERIAL 230191-RFP 
 
encourage communication between Maricopa County, the applicant, and Willdan prior to resubmitting a 
project for review to ensure questions related to the project are understood and addressed. Willdan 
notifies each applicant with two complete typewritten plan review letters outlining the documents reviewed 
and providing instructions to the applicant regarding document processing and a list of plan review 
comments. The plan review comments refer to appropriate sheets, details, or calculation pages and the 
code section of concern. Comments will specify the apparent code violation. Plan review comments, 
plans, and documents are returned directly to the designers until plans are approved. 
 
 
 
Our plan reviewers will schedule meetings during work hours to discuss and clarify plan review issues 
with designers, owners, and contractors. Resolutions of code issues are accomplished by telephone, 
email, or meetings prior to resubmitting corrected plans and documents. Willdan’s plan review staff will 
often meet with County staff, architects, developers, and homeowners prior to plan re-submittal to discuss 
any issues arising from the first review comments and address code compliance concerns or questions. 
These meetings help to expedite second (or third) plan reviews and move toward timely approvals. On 
larger or complex projects, Willdan will provide up-front consultation services with the design team to 
ensure all parties understand the standards and submittal requirements. 
 
Plan Review Timeline Schedule 
 
Willdan offers the timelines delineated below as our turnaround schedule for plan review: 
 
 
  
Project Initial Review 
Inspection Services 
Willdan's inspectors perform assigned inspections in accordance with County-adopted codes, regulations, 
procedures, and processes and with applicable state and federal codes. Inspectors review the permit 
package to verify that on-site conditions are consistent with the appropriate records for square footage, 
setbacks, heights, and other requirements that may be applicable. Inspectors comply with the County’s 
procedures for reporting inspection results, use County inspection correction forms, make appropriate 
entries onto the permit documents, and follow County procedures prior to finalizing a building permit. Our 
inspectors are thorough and spend the necessary time with the applicant during the inspection process to

SERIAL 230191-RFP 
 
explain any issues and what is needed to correct deficiencies. Additionally, our correction notices will 
contain the code section or other reference number, when applicable, that the applicant may need for 
reference to resolve an issue. When an inspection assignment is received, a qualified member of our 
inspection staff will be assigned to the project. Depending upon the complexity of the project, the staff 
assigned may perform multi-disciplined inspections. 
 
On complex projects, specialized inspection staff will be used to ensure that the highest quality of service 
is provided. The assigned staff will be available during the duration of the project with back-up provided 
based upon workload and expertise. Inspections will be performed by one inspector to maintain project 
continuity, unless approved to add additional staff due to work progress or project complexities. Assigned 
inspector(s) will respond to construction inspection requests as outlined by the adopted codes, as 
required by the plans and specifications, and as required by the designated representative of Maricopa 
County. Willdan staff will fully familiarize themselves with all forms and processes Maricopa County 
currently has in place or will provide Maricopa County with customized forms to accurately document the 
work performed on the project. Inspection records and reports will be maintained at Willdan’s office with 
copies provided to Maricopa County's designated representative for their use in project documentation 
and statis-tical reports. Willdan’s staff will conform to all of Maricopa County’s policies and procedures. 
Inspectors will report directly to Maricopa County's designee and will perform all tasks as requested. Plan 
review and inspection staff will attend all meetings deemed necessary by Maricopa County and Willdan 
management. 
 
Inspection Timeline Schedule 
Inspection requests that have been scheduled following the County’s established policies and procedures 
are completed the day they are assigned. Willdan has the organizational and the technical skills, as well 
as the staffing capacity, necessary to accommodate inspections on an emergency basis with as little as a 
four-hour notice. 
 
Quality Assurance 
Quality assurance and control procedures are critical to ensuring sound engineering practices and quality 
deliverables are produced for our clients. Mr. Patrick Johnson, PE, will serve Maricopa County as the 
Quality Assurance Manager. As a matter of practice, project-specific quality assurance activities are 
planned at the beginning of each project. Typical activities include ensuring the appropriate technical staff 
is assigned to the project, ensuring the proper project technical approach is selected, establishing a 
project schedule that meets internal Willdan and County deadlines, and determining the proper level of 
quality review. Mr. Johnson will coordinate with Ms. Autumn Wollmann, CBO, our proposed Project 
Manager, to assign a senior staff member(s) experienced in the required disciplines to perform quality 
reviews and ensure project objectives are met at project completion. Civil reviews will be managed under 
Building Safety and reviewed by or under the guidance of registered civil engineers. 
 
Our preliminary plan review County code compliance check serves as a pre-established guideline for our 
quality assurance and control methodologies for each project review. All correction letters are reviewed 
before they are returned to the applicant and the County. All projects requiring additional rechecks are 
reviewed by the same individual(s) to positively confirm that all questions and comments have been 
addressed before releasing the project back to the applicant and the County.
