Licensed Structural Engineer in Arizona: Your Complete Guide to Choosing the Right Professional

When your Arizona home or commercial building needs structural expertise, hiring a licensed structural engineer isn’t just recommended—it’s often legally required. Whether you’re planning a major renovation in Phoenix, building a custom home in Scottsdale, or addressing foundation issues in Tucson, understanding what a licensed structural engineer does and how to choose the right one can save you thousands of dollars and ensure your project’s safety and success.

This comprehensive guide covers everything Arizona property owners need to know about licensed structural engineers, from understanding their qualifications to selecting the best professional for your specific project.

What Is a Licensed Structural Engineer?

A licensed structural engineer is a specialized civil engineer who has met rigorous educational, experiential, and examination requirements to legally design and evaluate structures. In Arizona, these professionals hold either a Professional Engineer (PE) license or the more specialized Structural Engineer (SE) license issued by the Arizona Board of Technical Registration.

The Difference Between PE and SE Licenses

Professional Engineer (PE) License: This is the standard engineering license that allows engineers to practice civil engineering, including structural work. To obtain a PE license in Arizona, engineers must complete a four-year ABET-accredited engineering degree, gain four years of qualifying work experience under a licensed engineer, and pass both the Fundamentals of Engineering (FE) exam and the Principles and Practice of Engineering (PE) exam.

Structural Engineer (SE) License: This is an advanced specialty license that demonstrates expertise specifically in structural engineering. The SE license requires passing the 16-hour Structural Engineering exam, which is one of the most challenging professional engineering exams. While Arizona recognizes both PE and SE licenses for structural work, an SE license indicates additional specialization in complex structural analysis and design.

Both license types legally authorize engineers to stamp and seal structural drawings and calculations in Arizona, making them responsible for the safety and code compliance of their designs.

What Does a Licensed Structural Engineer Do?

Licensed structural engineers in Arizona provide essential services across residential, commercial, and industrial projects. Their core responsibilities include:

Structural Design and Analysis

Licensed structural engineers design the skeletal framework of buildings, ensuring structures can safely withstand Arizona’s unique environmental challenges, including extreme heat, monsoon winds, seismic activity, and soil conditions that vary dramatically across the state. They calculate loads, select appropriate materials, and create detailed construction documents that contractors use to build safely.

Building Evaluations and Inspections

When you’re buying a property with structural concerns, dealing with visible cracks, or experiencing foundation settlement—common in Arizona’s expansive clay soils—a licensed structural engineer can assess the severity of problems and recommend cost-effective solutions. These evaluations are crucial for older homes in historic Phoenix neighborhoods or properties affected by Arizona’s soil movement.

Remodeling and Addition Plans

Removing a wall in your Tempe home? Adding a second story to your Chandler property? A licensed structural engineer ensures these modifications won’t compromise your building’s integrity. They design support systems, specify beam sizes, and provide engineered drawings required for Arizona building permits.

Foundation Design and Repair

Arizona’s desert climate and varying soil types present unique foundation challenges. Licensed structural engineers design foundations suited to local soil conditions and develop repair strategies for existing foundation problems, from minor settling to significant structural movement.

Code Compliance and Permitting

Licensed structural engineers ensure all designs meet Arizona’s adopted building codes, including the International Building Code (IBC) and the International Residential Code (IRC), along with local amendments. Their stamped drawings are required for permit approval by cities and counties throughout Arizona.

Why Arizona Building Codes Require Licensed Structural Engineers

Arizona law and local building departments require licensed engineer involvement for many projects to protect public safety. Understanding when you need a licensed structural engineer helps you budget appropriately and avoid permit delays.

When Arizona Law Requires a Licensed Structural Engineer

You’ll need a licensed structural engineer in Arizona for:

  • Load-bearing wall removal or modification: Any changes to walls that support the weight of the structure above must be engineered and stamped by a licensed professional.
  • Structural additions: Adding square footage, especially second stories, requires engineered plans to ensure the existing foundation and framing can handle additional loads.
  • Foundation repairs: Significant foundation work, including underpinning, helical piers, or structural stabilization, requires engineering oversight.
  • Commercial construction: Nearly all commercial projects require comprehensive structural engineering and stamped plans.
  • Properties in special hazard areas: Homes in floodplains, high wind zones, or areas with known soil instability need additional engineering analysis.
  • Large residential projects: Custom homes, significant renovations, and projects over certain square footages require structural engineering in most Arizona jurisdictions.
  • Beam sizing and structural steel: Anytime structural beams or steel members are specified, a licensed engineer must calculate and specify appropriate sizes.

Building departments in Phoenix, Tucson, Mesa, Scottsdale, and other Arizona cities strictly enforce these requirements during plan review. Attempting to proceed without proper engineering can result in permit denial, construction delays, and potential liability issues.

How to Choose the Right Licensed Structural Engineer in Arizona

Selecting a qualified licensed structural engineer requires more than just finding someone with the right credentials. Here are the essential questions to ask and factors to consider when hiring a structural engineer for your Arizona project.

1. Verify Their Arizona License and Credentials

Before discussing your project in detail, confirm the engineer holds a current Arizona PE or SE license. You can verify licenses through the Arizona Board of Technical Registration website by searching the engineer’s name or license number. This quick step ensures you’re working with a legitimate professional authorized to practice in Arizona.

Look for additional credentials that demonstrate expertise:

  • SE license: Indicates advanced structural engineering specialization
  • ASCE membership: Shows involvement with the American Society of Civil Engineers
  • SEAoA membership: The Structural Engineers Association of Arizona membership indicates commitment to local industry standards and continuing education
  • LEED certification: Relevant if you’re pursuing sustainable or green building goals

2. Assess Their Arizona Project Experience

Arizona’s building environment is unique. Structural engineers familiar with local conditions will design more appropriate, cost-effective solutions. Ask about their experience with:

  • Arizona soil conditions: Experience with caliche, expansive clays, and varying soil bearing capacities across different Arizona regions
  • Desert climate considerations: Understanding of thermal expansion, extreme temperature fluctuations, and weathering effects specific to Arizona
  • Local seismic requirements: Arizona has specific seismic design requirements, particularly in areas like Yuma and along the Arizona-Mexico border
  • Monsoon wind loads: Engineers should understand Arizona’s seasonal high winds and their impact on structural design
  • Regional building codes: Each Arizona jurisdiction may have unique amendments to standard codes

Request examples of similar projects they’ve completed in your area. An engineer who has worked extensively in Phoenix understands different requirements than one who primarily works in Flagstaff, where snow loads become a significant factor.

3. Review Their Residential vs. Commercial Experience

Structural engineers often specialize in either residential or commercial work, though many handle both. If you’re a homeowner, you want someone comfortable with residential projects who can explain technical concepts in accessible terms. For commercial projects, look for engineers experienced with the specific building type you’re developing—whether retail, office, industrial, or multi-family.

Ask for their project portfolio and request to see:

  • Similar building types to your project
  • Projects of comparable size and complexity
  • Recent work that demonstrates current code knowledge
  • Examples of successful permit approvals with Arizona municipalities

4. Understand Their Process and Timeline

A professional licensed structural engineer should clearly explain their workflow for your specific project. A typical process includes:

  1. Initial consultation: Site visit and project discussion to understand your goals and constraints
  2. Structural assessment: Evaluation of existing conditions (for renovation projects)
  3. Preliminary design: Initial structural concepts and approach
  4. Engineering calculations: Detailed structural analysis and load calculations
  5. Construction drawings: Stamped plans suitable for permit submission
  6. Plan review support: Responses to building department comments or questions
  7. Construction observation (optional but recommended): Site visits during key construction phases

Ask for a realistic timeline. Simple residential projects might take 2-4 weeks, while complex commercial structures could require several months. Engineers who promise unusually fast turnaround times may cut corners or have capacity issues that could delay your project.

5. Clarify Their Knowledge of Arizona Permitting

Every Arizona city and county has unique permitting requirements and review processes. Phoenix operates differently than Tucson, and Maricopa County has different standards than Pima County. An experienced Arizona structural engineer should:

  • Prepare plans formatted for your local jurisdiction’s requirements
  • Understand typical plan review timelines in your area
  • Know how to address common plan check comments
  • Have established relationships with local building departments
  • Be available to answer questions during the permit review process

Ask directly: “How many projects have you permitted with [your specific city/county]?” Their answer will reveal their familiarity with your local process.

6. Get Transparent Fee Structures

Structural engineering fees in Arizona vary based on project complexity, building size, location, and the engineer’s experience level. Residential projects typically range from $1,500 to $5,000 for straightforward work like beam sizing or simple additions, while complex custom homes or commercial buildings can run $10,000 to $50,000 or more.

Request a detailed proposal that outlines:

  • Scope of services: Exactly what work is included
  • Deliverables: What you’ll receive (calculations, drawings, specifications)
  • Fee structure: Flat fee, hourly rate, or percentage of construction cost
  • Revision policy: Cost for design changes or additional iterations
  • Site visit fees: Whether construction observation is included or additional
  • Permit support: If assistance with plan check responses is included
  • Payment schedule: Deposit requirements and milestone payments

The lowest price isn’t always the best value. An experienced engineer who prevents costly construction errors or redesigns can save significantly more than their higher fee. However, all quotes should be reasonable for the Arizona market and the project scope.

7. Evaluate Communication and Availability

Strong communication prevents misunderstandings, delays, and costly mistakes. During your initial conversations, assess:

  • Responsiveness: Do they return calls and emails promptly?
  • Clarity: Can they explain technical concepts in understandable terms?
  • Listening skills: Do they understand your goals and constraints?
  • Availability: Will they be accessible during construction for questions?

Ask about their typical response time for contractor questions during construction. The best structural engineers remain available for Requests for Information (RFIs) and unexpected site conditions that may require design modifications.

8. Request References and Check Reviews

Reputable licensed structural engineers should readily provide references from recent clients. Contact at least three references and ask:

  • Was the project completed on time and within budget?
  • Were the plans approved without significant issues?
  • How did the engineer handle unexpected problems?
  • Would they hire this engineer again?
  • Did contractors find the plans clear and buildable?

Also check online reviews on Google, Yelp, and industry-specific platforms. Look for patterns in feedback regarding professionalism, accuracy, and customer service.

Red Flags to Avoid When Hiring a Structural Engineer

Protect yourself by watching for these warning signs:

  • No verifiable license: Anyone offering structural engineering services in Arizona must hold a valid PE or SE license
  • Unwillingness to provide references: Legitimate professionals have satisfied clients willing to speak on their behalf
  • Vague or unclear proposals: Professional engineers provide detailed scopes of work and fee structures
  • Pressure tactics: Reputable engineers don’t pressure you into immediate decisions
  • No errors and omissions insurance: Licensed engineers should carry professional liability insurance
  • Unfamiliarity with local codes: Arizona-specific experience is crucial for successful projects
  • Poor communication: If they’re difficult to reach during the proposal phase, expect worse during the project

Arizona-Specific Structural Considerations

Licensed structural engineers in Arizona must account for unique regional factors:

Expansive Soils

Many parts of Arizona, particularly in the Phoenix Valley, have expansive clay soils that shrink and swell with moisture changes. This causes foundation movement and requires special foundation designs, including post-tensioned slabs, deeper footings, or specialized drainage systems.

Extreme Temperature Fluctuations

Daily temperature swings of 40-50°F are common in Arizona, causing thermal expansion and contraction that engineers must consider in material selection and connection design.

Monsoon Winds

Summer monsoon storms bring sudden, powerful winds that can exceed 70 mph. Structural engineers must design roof systems, shade structures, and tall buildings to withstand these forces.

Seismic Activity

While not as seismically active as California, Arizona does experience earthquakes, particularly near the Arizona-Mexico border and in areas like Yuma. Buildings must meet seismic design requirements based on location.

Low Humidity Effects

Arizona’s dry climate affects material selection and construction details, particularly for wood framing, masonry, and exterior finishes.

Working With Your Licensed Structural Engineer: Best Practices

Maximize the value of your structural engineering investment:

Provide Complete Information

Share all relevant details about your project, including:

  • Property survey and title information
  • Existing building plans (if available)
  • Soil reports or geotechnical studies
  • Previous inspection reports
  • Budget constraints
  • Project timeline requirements

Be Available for Site Visits

Plan to be present during the engineer’s initial site visit to answer questions and discuss your vision for the project.

Ask Questions

If you don’t understand something in the plans or calculations, ask for clarification. Good engineers welcome questions and explain their design decisions.

Follow Recommendations

Structural engineers base their designs on safety factors and code requirements. Avoid requesting changes that compromise structural integrity to save costs.

Include the Engineer During Construction

Having your engineer available for construction questions ensures the project is built as designed and problems are addressed quickly.

These services ensure that your wall meets local building codes, safety requirements, and performs well under Arizona’s challenging soil and weather conditions. Check out our Civil Engineering and Design Services to hire your engineer today!


When Do You Need a Licensed Engineer for a Retaining Wall in Arizona?

In Arizona, you typically need licensed retaining wall engineering services when:

  • The wall exceeds 3–4 feet in height (depending on city)
  • It supports driveways, buildings, or slopes
  • It’s located near property lines or easements
  • Your local municipality, such as Scottsdale, Mesa, or Tucson, requires an engineering stamp

Even if not legally required, hiring a licensed engineer ensures safety, protects your investment, and increases property value.


Why Arizona Retaining Walls Require Specialized Engineering

Arizona’s geography and climate create unique engineering challenges:

1. Expansive Clay Soils

Common in Phoenix and Tucson, expansive clay swells when wet and shrinks when dry—causing intense pressure on walls. Proper design, drainage, and reinforcement prevent cracking or collapse.

2. Caliche Layers

Arizona’s hard caliche deposits complicate excavation and foundation anchoring. Experienced engineers know how to design footing and drainage systems that handle these conditions.

3. Extreme Temperature Swings

Arizona’s pavement can reach 160°F in summer and drop below freezing in winter. Licensed engineers use the right materials, joints, and reinforcements to prevent thermal cracking.

4. Monsoon Drainage

Sudden monsoon storms can dump inches of rain in hours. Without professional drainage design—weep holes, gravel backfill, and perforated drains—walls can fail quickly.

5. Seismic Stability

Arizona’s mild but present seismic activity requires that taller walls include earthquake-resistant design principles.


Types of Retaining Walls Common in Arizona

Cantilever Retaining Walls

Best for 4–20+ foot walls. Require complex calculations for reinforcement and footings—always handled by licensed engineers.

Gravity Retaining Walls

Ideal for decorative or shorter walls (under 4 feet). Even small walls benefit from professional drainage and soil design in Arizona’s expansive soils.

Segmental Retaining Walls (SRW)

Popular in residential and commercial Arizona landscapes. Most cities require an engineer’s stamp for walls over 4 feet.

Anchored / Tieback Walls

Used for steep sites or large commercial projects. These always require comprehensive retaining wall engineering services for safety and stability.


The Arizona Retaining Wall Engineering Process

Step 1: Site Assessment & Consultation

Your engineer visits the property to evaluate soils, slopes, and drainage, then recommends the best type of retaining wall for your Arizona location.

Step 2: Geotechnical Investigation

Soil borings and lab testing determine bearing capacity, lateral earth pressure, and drainage recommendations. Cost: $800–$2,500 for residential projects.

Step 3: Structural Design

The engineer performs load calculations and designs for overturning, sliding, and bearing stability. Drainage, weep holes, and backfill are included.

Step 4: Construction Documents & Stamped Plans

Your engineer provides sealed drawings and calculations that meet Arizona building codes—required for permits.

Step 5: Permit Application

Plans are submitted to your local city or county building department (Phoenix, Chandler, Mesa, Tucson, etc.) for approval.

Step 6: Construction Oversight

Engineers may perform site visits or field adjustments to ensure construction follows approved plans.

Step 7: Final Inspections

Your retaining wall is inspected and approved by Arizona authorities before it’s finalized.

Load-Bearing Walls and Foundations: When to Call an Engineer for Inspection

In Phoenix’s dynamic climate—where intense sun, shifting soils, and monsoon rains challenge building stability—understanding when your home’s load-bearing walls or foundation need professional inspection could save you thousands and protect your property. If you spot sagging floors, diagonal cracks, or bulging walls, it’s time to call a licensed engineer to conduct a structural evaluation. Schembri Engineers offers expert inspections across metro Phoenix, delivering peace of mind with Certified Home & Property Inspection Services.


What Are Load-Bearing Walls & Foundations?

A load-bearing wall supports weight from above (floors, roof, beams) and transfers those loads into the foundation. Unlike partition walls, removing or altering them without proper design can compromise structural integrity. The foundation anchors your home and resists forces like soil settlement or uplift; problems here often manifest as cracks, tilts, or uneven settlement. In Phoenix, expansive soils and desert conditions can exacerbate foundation stress.


Signs You Should Call an Engineer

You don’t need to wait for disaster. Here are warning signs that merit professional inspection:

SymptomWhat It May Indicate
Wide (> ⅛ in) or diagonal cracks in walls, especially near corners or windowsStructural shifting or foundation movement
Sagging or bouncing floorsDeflection in beams, joists, or inadequate support
Cracks in the foundation slab or footingFoundation failure or soil pressure
Doors or windows that stickFrame movement due to shifting walls
Bulging walls or separation between wall and ceilingLateral load issues or soil pressure
Settlement near footings or exterior wallsSoil subsidence or drainage-related erosion

When these symptoms appear, it’s best to schedule a structural inspection promptly.


The Role of the Engineer vs. a Contractor

  • A contractor can do repairs—fix cracks, underpin foundations, install beams—but is not always qualified to assess or design structural systems.
  • A licensed structural or civil engineer can diagnose root causes, perform load calculations, design structural solutions, and stamp plans for permit review. In Phoenix, adhering to municipal codes is critical. Before removing or altering load-bearing walls, an engineer’s design is often required to satisfy permitting procedures. Vir Structural Engineers

Hiring the right qualified engineer up front ensures your repairs are safe, sustainable, and code-compliant.


When You Should Definitely Call an Engineer (Phoenix Edition)

  1. During remodeling, additions, or wall removal – Anytime you plan to remove or punch through walls, especially load-bearing ones.
  2. Before buying a home – Structural inspections can reveal hidden foundation or wall issues.
  3. When cracks or movement appear – Elevated, spreading, or recurrent cracks should be evaluated.
  4. After natural events – If a storm, flood, or seismic event occurs, inspect structural components.
  5. Pre-permit work – Many Phoenix municipalities will reject permit applications without stamped structural plans.

What to Expect from a Structural Inspection

A professional inspection will typically include:

  • Visual and in-person examination of walls, beams, and foundation
  • Review of original construction documents (if available)
  • Measurements, mapping of cracks, and load path checks
  • Structural calculations (axial, bending, shear)
  • Recommendations and design options (repairs, reinforcements, load redistribution)
  • Stamped drawings for repair or retrofit
  • A clear report you can use with contractors or for permitting

Load-Bearing Wall Evaluations: What Arizona Homeowners Should Know

When it comes to remodeling or renovating your Arizona home, one of the most critical questions is: “Is this wall load-bearing?” A misstep in removing or altering a load-bearing wall without proper evaluation can lead to costly—and dangerous—structural failures. That’s why homeowners in Arizona should understand the essentials of load-bearing wall evaluations, the risks involved, and the role of expert engineers in ensuring your home remains safe, sound, and code-compliant.


What Is a Load-Bearing Wall?

A load-bearing wall carries weight from the structure above (roof, floors, upper walls) and transfers that load down to the foundation. Unlike non-bearing or partition walls, load-bearing walls are integral to your home’s structural integrity. Removing or modifying them without accounting for their load path can lead to sagging floors, cracked ceilings, or even collapse.


Why Load-Bearing Wall Evaluations Are Especially Important in Arizona

Arizona’s unique climate and building styles make load-bearing evaluations especially crucial:

  • Heat and expansion: The desert heat causes expansion and contraction in building materials, stressing structural components over time.
  • Seismic considerations: While not as seismically active as some states, Arizona’s occasional tremors (and building code requirements) demand careful structural design.
  • Older homes or unrecorded modifications: Many Arizona homes were altered over the years—without permits or professional guidance. Walls that once were non-bearing may now carry unexpected loads due to prior modifications.
  • Material types: Masonry, adobe, block, or concrete walls behave differently from wood-framed walls. Knowing how to evaluate each type under Arizona conditions is essential.

Because of these factors, Arizona homeowners cannot rely solely on experience or guesswork—they need qualified structural evaluations.


Key Steps in a Load-Bearing Wall Evaluation

  1. Review architectural and structural plans (if available).
    Original blueprints may indicate which walls are load-bearing. But in many homes, plans are lost or modified, so they’re just a starting point.
  2. Inspect framing and structural members.
    Engineers or inspectors will look at joist directions, beam placements, column alignments, and connections to determine load paths.
  3. Probe or remove finishes (where needed).
    In some cases, drywall, plaster, or finishes may be partially removed to reveal framing behind walls.
  4. Check foundation and roof/upper loads.
    The wall must be tied into appropriate foundations, and the load from above must be quantified (roof, second floor, mechanical loads, etc.).
  5. Perform calculations and verify load capacity.
    Engineers calculate axial, shear, and bending forces to confirm whether the wall or proposed modifications are safe.
  6. Design reinforcements or alternative load paths (if needed).
    If removal or alteration is planned, beams, headers, steel posts, or other structural members may be designed to carry the load safely.
  7. Permit and code review.
    Any changes must comply with Arizona building codes, local jurisdiction requirements, and structural safety standards.

Common Misconceptions & Risks

  • “Because it’s just drywall, it’s non-bearing.”
    Not true. A wall may look ordinary, but behind it could be critical framing.
  • “I can just add a header.”
    Headers must be sized correctly and properly supported. An undersized header or unsupported ends can fail.
  • “Load shifts will always go to footing automatically.”
    Without proper design, loads can shift erratically, overstressing neighboring walls or structure.
  • DIY is fine for small changes.
    Even minor adjustments to load paths can have cascading consequences. A professional evaluation is worth the cost.

When Should You Get a Structural Evaluation?

  • When removing, relocating, or recessing a wall in a renovation
  • When converting a single-story to a multi-story or adding mezzanines
  • When purchasing a home and signs of structural distress (cracks, sagging, uneven floors) are present
  • Whenever the existing layout seems inconsistent with expected framing (e.g. beams in awkward places)

Early evaluation prevents costly surprises mid-project and ensures safety.

What is NAOS? The Arizona Homeowner’s Guide to Natural Area Open Space

Natural Area Open Space (NAOS) is a protected part of a property in Arizona that is permanently designated to remain in its native desert state. While a homeowner owns the land, it is subject to an easement that restricts any building, landscaping, or clearing, making it a critical consideration for anyone buying, selling, or renovating a home in the region.

Understanding the Importance of NAOS

If you’re a homeowner or prospective buyer in Arizona, particularly in a city like Scottsdale, understanding NAOS (Natural Area Open Space) is essential. It’s a key component of the state’s efforts to preserve the Sonoran Desert. Simply put, NAOS is a deed-restricted area on a property that must be left in its natural condition, completely undisturbed by human activity.

The easement means that within the designated NAOS, you cannot:

  • Build new structures like pools, sheds, or additions.
  • Grade, fill, or excavate the land.
  • Clear, prune, or rake existing native vegetation.

The purpose of NAOS is to protect native vegetation, wildlife habitats, and natural drainage patterns. This not only preserves the beauty of the desert but also helps with flood control and maintains the area’s unique ecosystem.

Know Where Natural Area Open Space is Located on Your Property

Before you plan any home improvement project, it’s crucial to know if and where a NAOS easement exists on your property. This information is typically recorded with the county and can be found on a title report or the subdivision plat. Knowing the exact location is the first step in avoiding costly violations.

We often encounter situations where homeowners are surprised by NAOS restrictions. For example, we worked with a client who wanted to add a beautiful new patio and retaining wall to their backyard. Upon reviewing their property documents, we discovered a significant portion of their yard was in Natural Area Open Space . By understanding the easement early on, we were able to redesign the project to fit within the buildable area of the property, avoiding potential fines and the expensive process of seeking a variance.

This is where expert structural guidance is invaluable. A NAOS violation can be a major hurdle, but with the right planning, it doesn’t have to stop your project. Schembri Engineers specializes in navigating these complexities. We work with homeowners and builders to ensure that structural designs are not only safe and robust but also fully compliant with local regulations, including NAOS easements.

What Is the Difference Between a Survey and a Boundary Survey?


Introduction

A survey is a broad measurement and mapping of land, while a boundary survey focuses specifically on locating the exact property lines and corners of a parcel. In short, surveys show what’s on the land, and boundary surveys confirm where the legal boundaries lie.


What Is a Survey?

A survey is a broad term that refers to the process of measuring and mapping property, land, improvements, and topographical features. It may include:

  • Measuring distances, angles, elevation changes
  • Mapping physical features (such as structures, roads, trees, utilities)
  • Identifying easements, rights-of-way, flood zones, or environmental constraints
  • Producing maps or plats to show what’s on a property and its surroundings

Surveys can be required or helpful in many contexts: property purchase, site planning, construction, zoning compliance, land development, and even for obtaining permits.


What Is a Boundary Survey?

A boundary survey is a more specific type of survey. The focus is on determining the precise location of the property lines (boundaries) of a parcel of land. Key elements include:

  • Locating (or re-establishing) boundary lines based on recorded deeds, plats, monumentation, and Title documents
  • Identifying corners, property line markers, fences, walls that define ownership
  • Verifying legal descriptions
  • Determining whether structures or improvements encroach onto adjacent parcels

Boundary surveys are often needed for resolving property line disputes, subdividing land, obtaining mortgages, or ensuring that structures comply with setback requirements.


Key Differences Between a Survey and a Boundary Survey

FeatureGeneral SurveyBoundary Survey
ScopeBroad: topographic features, improvements, elevations, utilities, etc.Narrow: focused mainly on property lines, monuments, legal boundaries.
PurposeSite planning, building design, environmental assessment, grading, drainage, etc.Property ownership/legal issues, fences/setbacks, title insurance, subdivisions.
Legal weightCan inform many things; may not be sufficient alone for resolving boundary disputes.Usually used in legal, real estate, or title contexts; heavily based on deed/record evidence.
DeliverablesTopo maps, site plans, overall property layout, sometimes 3D data.Plat or map showing boundary lines, monuments/corners, legal description confirmation.
Typical Cost & TimeMore elements = more work. Often more expensive due to more data gathering (elevations, utilities, terrain).Sometimes less expensive if only lines; but if monuments are missing or deed records are complex, cost and time can increase.

When You Need One, or Both

Often, a property project requires both kinds of surveys (or parts of them). For example:

  • Buying property: you’ll often want a boundary survey to ensure what you’re purchasing matches legal record, alongside a general survey to assess topography and features.
  • Building an addition: you need to know boundary lines (to obey setback laws), but also elevations, existing structures, utility lines etc.
  • Subdivision or lot line adjustment: boundary surveys are essential to legally adjust lines; general surveys help with terrain, utilities, and infrastructure planning.
  • Dispute resolution: boundary surveys are typically the main tool; general surveys can provide context.

What’s the Difference Between a Civil Engineer and a Structural Engineer?

When you look at building homes, infrastructure, or commercial projects, you may hear people use the terms civil engineer and structural engineer interchangeably. While these roles overlap, each has distinct responsibilities, training, and specialties. Understanding the difference can help you know exactly who you need on your team—and how Schembri Engineers can deliver both.


What is a Civil Engineer?

A civil engineer is typically responsible for the planning, design, construction, and maintenance of infrastructure projects. This includes:

  • Site development: grading, drainage, utilities, roads, sidewalks
  • Infrastructure systems: stormwater management, sewage, flood control, water supply
  • Land use planning & transportation engineering
  • Public works projects: highways, bridges, airports, dams
  • Regulatory compliance: making sure designs meet local, state, and federal codes and permitting requirements

Civil engineers often look at the big picture—how a project fits within its environment, how to prepare a site, how to ensure access, manage water and infrastructure.


What is a Structural Engineer?

A structural engineer focuses more narrowly on the skeleton of buildings or other structures: the parts that carry loads and make sure the structure stands up safely. Core responsibilities include:

  • Designing structural elements: beams, columns, foundations, trusses, load-bearing walls
  • Load analysis: wind loads, snow loads, seismic loads, dead/live loads
  • Material selection: steel, concrete, wood, or composite materials
  • Ensuring structural integrity over time: durability, safety, serviceability
  • Inspection & evaluation: checking existing structures, analyzing damage, designing repairs

Structural engineering is deeply technical—analysis, modeling, safety factors—all focused on making sure that a structure won’t collapse, deform excessively, or fail in extreme conditions.


How the Roles Overlap (and Why Both Matter)

There is overlap. A civil engineer designing a site must work with drainage and foundation considerations, which involves structural knowledge. Conversely, a structural engineer must understand the site conditions (soil, slope, loads) which often involves civil engineering. Good projects require coordination between both disciplines.

A few examples:

What is neededCivil Engineer’s ContributionStructural Engineer’s Contribution
Building a new commercial building on undeveloped landDesigning the site layout, grading, utility connections, stormwater flow, access roadsDesigning the building’s foundations, framing, ensuring safe load-bearing design
Renovating an older buildingDetermining site constraints, utilities, permitsInspecting load capacity, designing structural reinforcement

Why Choose a Firm That Offers Both: The Schembri Engineers Advantage

At Schembri Engineers, we pride ourselves on being a full-service engineering & design firm that covers both civils and structural engineering (along with mechanical/plumbing, electrical, and inspection services).

Here are some ways Schembri Engineers stands out:

  • Decades of experience: Established in 1985, family-owned and operated. Over 40 years of solving engineering challenges across Arizona and Nevada.
  • Comprehensive design services: We perform Civil Design & Analysis and Structural Design & Analysis, so you get both site-/infrastructure-level expertise and structure-level safety and integrity from the same trusted team.
  • Inspection & evaluation capabilities: We provide special inspections, defect investigation, construction forensics, etc.—ensuring that structures are built (and maintained) properly.
  • Professional credentials: Many of our inspection engineers are board-certified via the Building Inspection Engineering Certification Institute (BIECI); we’re members of NABIE and the NSPE.
  • Proven track record: Over 15,000 satisfied clients, recognized locally (2023 Angi Super Service Award).

When you need work that involves both civil and structural engineering—say, a new building, or repairs to an existing one—having a single firm that understands both disciplines means fewer gaps, smoother coordination, lower risk, and better outcomes.


When Do You Need Each (or Both)?

Here are some scenarios:

ScenarioYou Need Civil EngineeringYou Need Structural EngineeringBoth
Building a new house on a graded lot✔️ site grading, utilities✔️ foundation & framing✔️
Replacing a retaining wall after soil erosion✔️ site grading and drainage✔️ structural wall design✔️
Adding a second story to an existing building✔️ permits, site impact✔️ load capacity, framing reinforcement✔️
Building a road or infrastructure (non-building)✔️ primarily civil✔️ if bridges or structures are involved

Tips for Working Successfully With Your Engineers

  • Clearly define what you want: budget, timeline, functionality (e.g., parking, load-bearing requirements, seismic or wind concerns).
  • Ensure you hire licensed professionals: structural engineers should be licensed P.E.s; inspections by certified inspectors. Schembri Engineers provides licensed Professional Engineers for designs and board-certified inspectors for evaluations.
  • Talk about soil and site conditions early: poor soil types, steep slopes, expansive soils (common in parts of Arizona) & drainage issues can significantly affect both civil and structural design.
  • Plan for inspections & evaluation, not just design: catching issues early (foundation problems, structural issues) saves cost and delays.

Civil engineers and structural engineers are both essential

Civil engineers focus on how a project fits into, impacts, and works with land, infrastructure, and environment; structural engineers ensure the safe, stable skeleton of what is built. When they work together, projects are safer, more efficient, more durable, and cost-effective.

At Schembri Engineers, you don’t have to choose one or the other—you get both. Whether you’re starting from the ground up or reinforcing existing structures, our team has the civil, structural, inspection, and evaluation expertise to guide your project from plan through construction and beyond.

If you’re planning a project in Arizona or Nevada and want engineers who truly understand both civil and structural demands, contact Schembri Engineers today. Let’s make sure whatever you build is safe, sustainable, and built to last.
