Advanced Structural Framing, Building Science & Continuing Education for Residential Construction in Southern Maine

Why I Continue Learning the Engineering Behind Residential Construction

I've always believed that experience is only half of becoming a better builder. The other half is understanding why things are built the way they are.

After years of framing houses, building custom decks, remodeling kitchens, adding onto homes, and opening walls that have been hidden for decades, you start to recognize patterns. Some framing has been sitting there for fifty or a hundred years without a problem because it was designed, built, and connected correctly. Other failures have nothing to do with bad lumber. They're the result of an interrupted load path, a missing connector, too much material removed from a framing member, or someone making a structural change without understanding what that piece of the house was actually doing.

One habit I've developed over the years is asking a simple question every time I uncover older framing:

Why did they build it this way?

Sometimes the answer is obvious. Sometimes it takes a while to figure out. Either way, I've found that understanding the reasoning behind an older carpenter's work usually teaches me more than immediately assuming they were wrong. Construction has changed, building codes have changed, engineering has changed, but there's almost always something to learn from understanding how another builder approached the problem.

The same mindset is what led me to continue my education through Simpson Strong-Tie. I wasn't looking for another certificate to hang on the wall. I wanted a better understanding of the engineering behind the work I already do every day. I wanted to know why one connector is specified instead of another. Why one hole location is acceptable while another weakens the member. Why one framing detail performs better under load than another. The more I understand the engineering behind those decisions, the better decisions I can make in the field.

One thing I've learned over time is that the best builders don't just keep building—they know when to stop building. Throughout every framing project there are points where I stop the crew and we inspect everything before moving forward. Are the walls still square? Is every required strap installed? Has the blocking been completed? Is every sheet fully nailed? Are we about to cover something that should be corrected now instead of discovered later? Those inspections take minutes, but they prevent mistakes that become expensive once the project moves to the next stage.

I've also learned that experience should never replace verification. One mistake I still see in this industry is skipping a five-minute conversation with an engineer or assuming a structural detail without taking the time to verify it. Most of the time the answer is simple, but asking the question is what separates hoping something is right from knowing it's right.

Every course in this series reinforced the same idea I've seen on jobsites for years: a house is one complete structural system. Roof loads transfer into walls. Walls transfer into floor framing. Floor framing transfers into beams, posts, foundations, and finally the supporting soil. Every joist hanger, anchor bolt, beam pocket, structural screw, bearing point, and connector has a job to do. When one component is overlooked or improperly modified, the effects rarely stay isolated to that one location.

The courses that follow cover subjects including continuous load paths, roof framing, structural modifications, shear wall design, deck construction, flood-resistant building practices, and engineered wood systems. They're different topics, but they're all connected by the same principle: understanding how every part of a structure works together instead of looking at each component independently.

The longer I've worked in construction, the more convinced I've become that good building is rarely the result of one big decision. It's the accumulation of hundreds of small decisions made correctly—asking one more question, checking one more measurement, understanding one more engineering detail, and taking the time to figure out not just how something should be built, but why it's built that way in the first place.

Continuous Load Path

A foundational principle of structural engineering—and one of the concepts that has changed how I look at every framing project.

One of the biggest misconceptions I see is the idea that a house is simply a collection of boards nailed together. In reality, a properly built house behaves as one interconnected structural system. Gravity doesn't care where one carpenter stopped framing and another trade started working. Snow loads, wind uplift, lateral forces, and occupant loads all follow the same path through the structure, and if that path is interrupted, the building has to redistribute those forces somewhere else.

That's the idea behind a continuous load path.

Every structural load begins somewhere. A snow load bears on the roof sheathing, transfers into rafters or trusses, moves through bearing walls, floor framing, beams, posts, sill plates, anchor bolts, foundations, and finally into the supporting soil. Wind works in the opposite direction, creating uplift forces that try to separate those same components. The strength of the structure depends less on any single piece of lumber than on how effectively every connection transfers those forces to the next component.

Over the years, I've noticed that many structural problems don't start with undersized framing members. They start with interrupted load paths. A missing connector, an improperly fastened ledger, inadequate bearing, poorly detailed beam support, or a field modification that seemed insignificant at the time can change how loads move through the structure. Houses are remarkably forgiving, but they're also predictable—loads always find a path. The goal is to make sure it's the one the structure was designed to use.

This course reinforced that philosophy by digging deeper into the engineering behind load transfer. Topics included gravity loading, live loads, snow loads, wind uplift, tributary areas, diaphragms, collectors, hold-down systems, anchor bolts, structural connectors, bearing requirements, and the importance of maintaining uninterrupted force transfer from roof to foundation. It also highlighted something that doesn't get enough attention in day-to-day construction: connectors aren't accessories. They're structural components with engineered load capacities, installation requirements, fastener schedules, and design limitations that are every bit as important as the framing members they connect.

The biggest takeaway I had from this course was simple. Good framing isn't just about making everything straight, level, and square. It's about understanding how every rafter, joist, beam, wall, connector, and fastener contributes to the structural behavior of the building as a complete system. Once you begin looking at houses through that lens, you don't just see lumber—you see load paths, force transfer, and hundreds of individual details working together to create one durable structure.

Code Requirements for Conventionally Framed Roofs

Residential roof framing is one of the best examples of structural engineering hidden in plain sight.

One thing I've learned after framing and remodeling homes is that roofs are often underestimated. Most people see shingles, fascia, and trim. Underneath all of that is a structural system that's responsible for collecting dead loads, live loads, snow loads, and wind uplift, then distributing those forces safely throughout the rest of the building. Every rafter, ridge member, ceiling joist, valley, hip, bearing wall, beam, and connector has a specific purpose, and changing one part of that system almost always affects another.

Conventional roof framing isn't simply about cutting rafters to the correct pitch. Every roof is a balance of compression, tension, bearing, and load transfer. Ridge boards, structural ridge beams, collar ties, rafter ties, ceiling joists, purlins, and bearing walls each perform different structural functions depending on the geometry of the roof. Understanding when each system is appropriate is far more important than simply following a framing layout.

One topic I found particularly valuable throughout this course was how roof geometry influences structural behavior. Features such as hips, valleys, dormers, intersecting rooflines, cathedral ceilings, and large open floor plans create additional load paths that must be accounted for during framing. As homes become more architecturally complex, roof systems become significantly more than repetitive rafters spanning between two walls. Proper bearing, continuous support, engineered beam design, and connection detailing become increasingly important as loads are concentrated into fewer structural members.

The course also reinforced something I've seen repeatedly in older homes: the framing itself is often not what fails. More often, problems develop where framing members connect to one another. Hurricane ties, framing anchors, structural screws, hold-down systems, and engineered connectors aren't simply hardware—they're designed structural components with tested load capacities and specific installation requirements. Using the correct connector, the specified fasteners, proper edge distances, and approved installation methods is just as important as selecting the correct framing member.

Modern residential building codes continue to evolve as research improves our understanding of structural performance. Snow loads, wind exposure, uplift resistance, diaphragm action, and engineered connection systems all influence how conventionally framed roofs are designed today. While every house presents its own structural challenges, the underlying engineering principles remain consistent: maintain continuous load paths, provide adequate bearing, minimize unintended load concentrations, and ensure every structural connection is capable of transferring the forces it's intended to resist.

One of my biggest takeaways from this course is that good roof framing isn't measured by how quickly it goes together. It's measured by how well every component works together after the drywall is installed and the framing is no longer visible. When the geometry is correct, the connections are properly detailed, and the loads have a predictable path through the structure, the roof becomes part of a complete structural system designed to perform reliably for decades.

Boring and Notching in Wood-Frame Construction

Every hole drilled into structural framing changes the way that member carries load. The question isn't whether it can be drilled—it's where, how much, and why.

One of the easiest mistakes to make during construction is assuming that a framing member has "extra wood" that can simply be removed to make room for plumbing, electrical, or HVAC. In reality, every joist, stud, rafter, beam, and engineered framing member was designed to resist very specific forces. Removing material changes the cross-section of that member, which changes how it behaves under load.

Something I've noticed over the years is that most framing failures don't happen because someone drilled one perfectly placed hole. Problems usually begin when multiple trades each remove "just a little more." One notch becomes a larger notch. One hole becomes two. Utilities are rerouted. Before long, a member that's supposed to carry thousands of pounds no longer has the section properties it was originally designed with.

This course did an excellent job explaining the engineering behind those limitations. Structural members don't experience the same stresses throughout their entire depth or length. Bending moments, shear forces, compression, tension, bearing, and deflection all vary depending on span length, loading conditions, and support locations. That's why building codes permit boring and notching in some locations while prohibiting it in others. Those limitations aren't arbitrary—they're based on how wood actually performs under load.

The course also reinforced an important distinction between conventional dimensional lumber and engineered wood products such as LVLs, LSLs, PSLs, glulam beams, and wood I-joists. While sawn lumber follows the prescriptive requirements of the International Residential Code, engineered members are manufactured to specific design criteria and often have manufacturer-developed boring schedules that differ significantly from conventional framing. Field modifications outside those published requirements can substantially reduce structural capacity and may require engineered repairs.

One takeaway that stood out to me is that protecting structural capacity often starts long before the first hole is drilled. Good planning between the framing, plumbing, electrical, and HVAC trades usually produces a cleaner installation while preserving the integrity of the framing system. Coordinating mechanical runs, understanding where loads are being transferred, and recognizing when an engineered solution is required can eliminate problems before they ever reach the jobsite.

The more structural remodeling I do, the more I appreciate that good framing isn't just about what gets installed—it's also about knowing what shouldn't be removed. Understanding how section loss affects load transfer, stiffness, and long-term structural performance makes better decisions possible long before drywall ever covers the framing.

Shearwall Design

Most people understand that walls hold up a roof. Far fewer realize that some walls are also responsible for keeping the entire house from moving sideways.

One thing I've learned remodeling older homes is that every wall has a purpose until you prove otherwise. Some walls carry vertical loads. Others are primarily partitions. But certain walls are part of the building's lateral force-resisting system, meaning they're designed to resist horizontal forces generated by wind and transfer those loads safely into the foundation. Remove or significantly alter one of those walls without understanding its function, and you've changed how the entire structure responds to loading.

That's the role of a shear wall.

A properly designed shear wall isn't simply a stud wall covered with plywood or OSB. It's an engineered assembly made up of framing members, structural sheathing, boundary members, blocking, fastening schedules, hold-downs, anchor bolts, collectors, and a continuous load path that transfers lateral forces from the roof and floor diaphragms into the foundation. Every component contributes to the overall capacity of the system, and changing one detail—whether it's nail spacing, panel layout, anchorage, or connection hardware—can affect the performance of the entire assembly.

What I appreciated most about this course was that it explained why these details matter instead of simply stating code requirements. Wind loads don't disappear because a wall was removed during a remodel. They have to be transferred somewhere. As floor plans become more open and larger wall sections are replaced with beams and wide openings, the remaining structure has to compensate for the loss of lateral resistance. Understanding concepts such as overturning, diaphragm action, collector elements, aspect ratio, and load transfer helps explain why certain framing details become increasingly important as structures become more complex.

The course also reinforced how interconnected residential framing really is. Roof diaphragms transfer lateral forces into shear walls. Shear walls transfer those forces through sill plates, anchor bolts, and foundation systems before they're ultimately dissipated into the supporting soil. Interrupting that load path at any point doesn't eliminate the load—it simply forces it to find another route, often through structural components that were never intended to resist those forces.

One of my biggest takeaways from this training is that structural remodeling isn't just about replacing a wall with a larger beam. It's about understanding how that wall participated in the structural behavior of the house before it was modified. The more experience I gain, the more I appreciate that successful remodeling depends on respecting the way a building was designed to transfer loads, not just the way it was originally framed.

Deck Inspection for New and Existing Construction

Decks rarely fail because the decking wears out. More often, they fail because the structural details underneath were never designed, installed, or maintained the way they should have been.

I've rebuilt enough decks to notice a pattern. The visible problems—loose railings, sagging framing, rotted decking, or uneven stairs—are usually symptoms of something happening underneath. The real structural issues are almost always found where loads are transferred from one component to another. Ledger connections, beam bearing, post attachment, footing design, joist hangers, lateral load connectors, and corrosion around structural hardware deserve far more attention than the decking itself.

A deck is simply another structural framing system. Like the framing inside a home, it relies on a continuous load path that transfers gravity loads, live loads, snow loads, and lateral forces safely into the supporting foundation. Every joist, beam, post, connector, footing, and fastener contributes to that structural system. When one connection is compromised, the effects often extend well beyond that single location.

One part of this course that reinforced my own experience was the emphasis placed on ledger attachment. The ledger board is one of the most highly loaded connections in residential deck construction, yet it's also one of the most commonly installed incorrectly. Proper flashing, approved structural fasteners, engineered lateral load connectors, adequate rim board attachment, and moisture management all work together to create a durable connection capable of supporting the deck throughout its service life. A deck isn't only resisting the weight of people standing on it—it's also responding to seasonal movement, snow accumulation, wind loading, and decades of environmental exposure.

The course also examined the relationship between preservative-treated lumber, connector coatings, fastener compatibility, and long-term corrosion resistance. Modern pressure-treated lumber contains chemical preservatives that can accelerate corrosion when incompatible hardware is used. Selecting hot-dip galvanized or stainless-steel connectors, structural screws, bolts, and anchors that are compatible with the framing materials is a structural decision, not simply a material selection.

Another point that stood out to me is that good deck construction starts long before the first deck board is installed. Proper footing layout, post alignment, beam sizing, joist spacing, connection detailing, drainage, flashing, and ventilation all influence how that structure performs years down the road. Most structural deficiencies don't appear overnight—they develop gradually as moisture, movement, corrosion, and loading expose weaknesses that were built into the deck from the beginning.

One thing experience has taught me is that every deck tells a story once you start looking closely. Fastener corrosion, crushed wood fibers beneath hardware, improper bearing, differential settlement, inadequate flashing, or overloaded framing all leave clues about how the structure has performed over time. This course reinforced the importance of understanding those details and approaching deck construction as a complete structural system rather than a collection of individual components.

Buildings and Homes in Flood Hazard Areas

Flood-resistant construction isn't simply about elevating a building. It's about understanding how water changes the structural demands placed on every connection, foundation, and framing assembly.

One thing I appreciate about studying construction in flood hazard areas is that it forces you to think differently about structural performance. Under normal conditions, residential structures are primarily designed to resist gravity, snow, wind, and occupant loads. During a flood event, those same structures may also be subjected to hydrostatic pressure, hydrodynamic forces, debris impact, buoyancy, scour, erosion, and prolonged moisture exposure. The engineering priorities change because the loading conditions change.

One of the biggest takeaways from this course was the importance of designing the entire structural system—not just the foundation—to perform under those conditions. Foundations, anchorage, continuous load paths, structural connectors, corrosion-resistant fasteners, preservative-treated lumber, drainage, and moisture management all contribute to how well a structure performs during and after a flood event. The structural capacity of a building depends not only on its framing members but also on the durability of the connections holding those members together after years of environmental exposure.

The course also reinforced how coastal construction presents challenges beyond simply meeting minimum code requirements. Salt-laden air accelerates corrosion, repeated wetting and drying cycles affect wood movement, and aggressive environmental conditions place additional demands on structural hardware, flashing systems, anchors, and fastening methods. Connector selection, protective coatings, material compatibility, and proper detailing become increasingly important when long-term durability is the objective.

Another concept I found valuable was understanding how seemingly small design decisions influence the overall resilience of a structure. Proper elevation, freeboard, foundation detailing, breakaway wall design where applicable, drainage, ventilation, and maintaining uninterrupted load paths all contribute to reducing structural damage while improving the building's ability to recover after severe weather events.

Although not every home is constructed within a designated flood hazard area, the engineering principles discussed throughout this course extend well beyond floodplain construction. Moisture management, corrosion resistance, connection durability, and thoughtful structural detailing improve the long-term performance of residential buildings in virtually every environment. Understanding how structures behave under the most demanding conditions often leads to better construction decisions under everyday conditions as well.

Decks, Porches, and Boardwalks in Flood Hazard Areas

Exterior structures are exposed to some of the harshest conditions found in residential construction. Unlike the protected framing inside a home, they're expected to resist weather, moisture, ultraviolet exposure, seasonal movement, and, in coastal environments, flooding and accelerated corrosion—all while remaining structurally reliable for decades.

One thing I've come to appreciate is that a well-built deck isn't simply a smaller version of a house. Exterior structures experience constant expansion and contraction, repeated wetting and drying, freeze-thaw cycles, and in many coastal locations, continuous exposure to salt-laden air. Every one of those conditions affects framing, fasteners, structural connectors, flashing details, and the long-term durability of the assembly.

This course reinforced how dramatically structural design changes when flood hazards are introduced. Foundations, piles, piers, footings, lateral bracing, uplift resistance, continuous load paths, and connection detailing all become increasingly important as structures are exposed to hydrodynamic forces, debris impact, scour, erosion, buoyancy, and wave action. Under these conditions, every connection must not only support design loads but also remain durable after years of environmental exposure.

One area I found particularly valuable was the discussion surrounding material compatibility and corrosion resistance. Modern preservative-treated lumber, stainless steel hardware, hot-dip galvanized connectors, structural screws, protective coatings, and proper flashing details all work together to extend the service life of exterior framing systems. Selecting the appropriate hardware isn't simply a matter of corrosion resistance—it's also about maintaining the structural capacity of the connections throughout the life of the structure.

The course also emphasized that good exterior construction is driven by detailing as much as structural design. Drainage, ventilation, moisture management, bearing surfaces, connector installation, fastening schedules, and proper load transfer all influence how well decks, porches, docks, and boardwalks perform over time. Small installation details that seem insignificant during construction often become the deciding factor in long-term durability years later.

The biggest takeaway for me was that exterior structures demand a different mindset than interior framing. They're continuously exposed to conditions that challenge every component of the structural system. Designing and building with those conditions in mind—from foundation to fastener—produces structures that are not only code-compliant, but capable of performing reliably in some of the most demanding environments residential construction encounters.

Midrise Timber & Wood-Frame Multifamily Housing

One of the things I enjoy most about construction is that the engineering principles don't change simply because a building gets bigger. The same fundamentals that apply to a custom home—load paths, bearing, lateral stability, connection design, and structural continuity—also apply to larger and more complex wood-frame buildings. The difference is that as structures grow in size, there's less room for error.

This course explored the engineering behind modern timber and wood-frame construction, including structural load transfer, diaphragm behavior, lateral force-resisting systems, connection detailing, redundancy, and the interaction between floor systems, shear walls, collectors, beams, columns, and foundations. While the scale of these buildings differs from typical residential construction, the structural principles governing their performance remain remarkably consistent.

One concept that stood out to me is how every structural system depends on the uninterrupted transfer of forces throughout the building. Loads rarely travel in a straight line. They move through framing members, diaphragms, collectors, engineered connectors, bearing points, and foundations before ultimately reaching the supporting soil. As buildings become larger and framing systems become more complex, understanding those load paths becomes increasingly important because every connection influences the behavior of the structure as a whole.

The course also examined advances in engineered wood products, including laminated veneer lumber (LVL), laminated strand lumber (LSL), parallel strand lumber (PSL), glulam beams, mass timber applications, and modern connection systems that continue expanding the capabilities of wood construction. These products have transformed residential framing by allowing longer spans, larger openings, improved dimensional stability, and structural solutions that weren't practical only a few decades ago.

One thing I appreciate about studying larger structural systems is that they reinforce good habits on smaller projects. Whether framing a custom home, installing an engineered beam during a remodel, or constructing a residential addition, the same questions always apply. Where are the loads going? How are they transferred? Where are the bearing points? What happens if one component is modified? Thinking through those questions before construction begins almost always leads to better framing decisions.

The biggest takeaway from this course wasn't learning how to build taller buildings. It was developing a deeper appreciation for how engineered wood construction continues to evolve. The more I study structural framing, the more convinced I become that good builders never stop learning. Materials improve, connection systems evolve, building science advances, and every opportunity to better understand those changes ultimately contributes to stronger, more durable, and better-performing residential construction.

Continuing to Learn the Trade

The longer I work in construction, the more I realize that experience and education aren't competing ideas—they build on each other.

No classroom can teach what years on a jobsite will. Construction teaches you that your body is one of the most valuable tools you own, and if you expect to build for decades, you have to take care of it the same way you take care of every other tool. It teaches you that every trade depends on the others, and that a good lead carpenter isn't just building walls—he's coordinating people, sequencing work, and keeping everyone moving toward the same finished vision.

One habit I've developed over the years is asking a simple question whenever I open an older home:

Why did they build it this way?

Sometimes the answer is obvious. Sometimes it isn't. Every framing decision, every beam, every notch, every bearing point, and every structural connection tells part of the story. Even when I find something I wouldn't build the same way today, I want to understand the reasoning before I change it. I've found that's one of the fastest ways to become a better builder—learn from the people who came before you, understand what they got right, recognize what has changed, and keep moving forward.

I've also learned that some of the best builders aren't necessarily the fastest builders. They're the ones who know when to stop. Throughout every project there are moments when progress pauses and the entire job gets inspected before anyone moves forward. Is every wall square? Has every connection been completed? Is all required blocking installed? Has every structural strap been installed? Is the sheathing fully fastened? Are we building exactly what we intended to build? Taking a few minutes to verify the work before covering it up often prevents hours—or days—of corrections later.

Another lesson experience has reinforced is that assumptions are expensive. One mistake I still see in this industry is skipping the five-minute phone call to an engineer, failing to verify a detail in the plans, or assuming a structural condition without documenting it. Most of the time those conversations are straightforward, but they're often the difference between hoping something is correct and knowing it is. Good builders rely on experience. Great builders also know when to ask questions.

People occasionally ask whether continuing education is still necessary after years in the trade. My answer is that it depends on what you're trying to become. There are builders with decades of experience who have forgotten more than many people will ever learn, and some of those individuals are the ones teaching these courses. At the same time, I've never taken a technical course without learning something I didn't know before. Sometimes it's a new connector, a revised code provision, a different framing detail, or simply a better explanation of why something I've been doing works the way it does. Those small improvements accumulate over time.

I don't believe anyone ever masters construction completely. Materials change. Building science evolves. Engineered products improve. Research continues. Every project presents a different challenge, and every challenge is another opportunity to learn something new. That's one of the reasons I continue investing in education. Not because experience isn't valuable, but because experience becomes even more valuable when it's paired with a better understanding of the engineering and building science behind the work.

At the end of the day, good construction isn't usually defined by one dramatic decision. It's the result of hundreds of small decisions made correctly—asking one more question, checking one more measurement, installing one more connector exactly as intended, and taking the time to understand not only how something should be built, but why it should be built that way.
