Design-Build Glazing in Centennial
What design-build glazing actually means
Design-build glazing is when a single firm works with you from concept through installation to design the glass system, specify the materials, and then build it. The glazier sits at the design table alongside the architect and general contractor, not just at the end waiting for a set of specifications. You get one accountable firm for both the design decisions and the execution.
This differs from traditional spec-and-bid, where an architect specifies every detail on paper, then glaziers bid against that fixed spec. Design-build puts the glazier's structural knowledge and real-world install experience into the design itself, before anything is ordered.
When your project needs design-build instead of spec-and-bid
You need design-build when the schedule is tight, when the building structure isn't yet locked in, when the budget has room for value engineering, or when you want to avoid costly changes mid-install.
Common triggers: a fast-track general contractor who needs glazing input before framing is done; a budget that needs optimization without cutting quality; a building with complex geometry or mixed facade types; or a property manager who has occupied tenants and cannot afford a stoppage.
Design-build also works when the architectural spec was written without glazing expertise on site. We've walked into projects where the spec created assembly conflicts, excessive mullion weight, or thermal bridging problems that only show up when someone has fabrication experience in the room.
How Element13 runs design-build glazing projects
We start with a design assist meeting. You bring the architectural intent, square footage, occupancy, and any constraints. We bring structural silicone sealant knowledge, thermal break options, AAMA ratings, code compliance, and the ability to predict install logistics on your actual site.
From that meeting, we provide outline specifications, material options, and a preliminary assembly. We identify code triggers: IBC Section 2406 safety glazing requirements, wind load zones, seismic considerations, and thermal performance targets. Then we work with your design team to lock the system before drawings go final.
Once approved, our in-house fabrication facility builds the units and assemblies according to the design. Our NACC Master-Certified glaziers then coordinate the installation schedule around your operational needs.
Why Element13's process catches problems early
We employ union-trained, NACC Master-Certified glaziers. That certification means they've passed structural knowledge, sealant chemistry, and installation protocol exams that spec-readers don't take. When our glaziers sit in a design meeting, they catch things.
Example: a typical spec might call for a curtain wall system with a standard thermal break. Our team can ask whether the building has slab-edge heads or stack joints, how much drainage is planned, what the actual wind load is at height, and whether the spacer selection matches the climate. That conversation saves change orders later.
We also have in-house air and water testing capability. Before installation, we can run ASTM E330/E330M structural performance testing and ASTM E1300 glass load resistance on sample units. We don't rely on lab certs alone; we test your actual assembly.
What happens during the design phase
First, we gather site data: building dimensions, occupancy status, weather exposure, adjacent spaces. We review the architectural drawings, mechanical plans, and any structural details that affect the glazing interface.
Second, we evaluate options. Low-E coatings and U-value performance for SHGC targets. Insulated Glass Units with Argon gas fill versus standard double-strength. Laminated safety glass locations per code. Structural silicone versus pressure plates and gaskets, depending on the frame and sightline requirement.
Third, we detail the connection points. Flashing transitions, weep holes, desiccant spacers, and warm-edge spacer selection. Thermal break materials (polyamide or polyurethane) for thermal transmittance control. Anodized, painted, or Kynar aluminum frame finishes based on maintenance and durability expectations.
We document this in outline specs and forward them to your architect. No surprises at bid. No contractor confusion at install.
How we handle measurements when the building structure isn't ready
This is common in fast-track projects. The curtain wall system needs to be ordered before the facade is fully framed.
We work with the structural engineer to establish a tolerance envelope: a +/- range for header heights, column faces, and slab elevations. Our field team then coordinates with the GC's framing crew to confirm actual dimensions as the structure progresses.
If the structure falls outside tolerance, we flag it immediately. We adjust the system in our shop before fabrication, not during installation. This prevents a crew showing up with units that don't fit.
We also hold a pre-fabrication site visit once framing is near complete. We measure the actual opening sizes, confirm corner conditions, check for plumb and level, and document anything that affects the glass assembly. That real data goes back to fabrication before a single unit is cut.
Mixing curtain wall and storefront on the same elevation
Yes, and it's done often. Many projects have a curtain wall for the upper facade and storefronts or glazed partitions at the street level.
The trick is that the two systems use different structural frames, different sealant protocols, and different pressure profiles. A curtain wall uses structural silicone sealant and is designed for full wind load transfer. Storefronts use mechanical pressure plates and gaskets, designed for lower structural loads.
During design-build, we detail the transition. We specify where the curtain wall mullions stop, how the storefront header transitions to the curtain wall sill, how flashing and drainage flow from one system to the other, and what finish transitions look acceptable.
Our in-house fabrication and assembly means we can build both systems in the same shop, coordinate the delivery schedule, and show up with matching install teams. You get one firm accountable for both.
If you're planning a tenant improvement glazing project with mixed facade types, this is where design-build earns its cost back.
What testing does commercial glazing need before installation
Testing requirements depend on the system type and the code jurisdiction. We work within Denver and statewide IBC requirements.
Structural silicone glazing systems require ASTM C1394 inspection cycles on the sealant bond. We sample and test the joint at cure intervals to confirm adhesion.
Insulated Glass Units need ASTM C1521 adhesion testing on warm-edge spacers and sealant to ensure the unit stays sealed over time.
Full assembly testing under ASTM E330/E330M and ASTM E1300 simulates the actual wind load and glass deflection your building will experience. We test a representative unit from each fabrication batch.
All IGU assemblies get a desiccant spacer inspection and moisture check before shipment. Low-E coating inspection confirms the correct surface is faced outward (coating surface 2 or 3, depending on the design).
We run these tests in-house. You get the results before units leave our facility. If something fails, we know it before the crew is on site.
How we install while your building stays occupied
Occupied buildings require scheduling that respects tenant operations. Early mornings, evenings, weekends, or phased sections.
During design-build, we scope the install into phases. A floor per week, or a section per phase, depending on the building layout and your tolerance for disruption. We coordinate with building management on access, elevator holds, and security.
Our installation crews are union-trained and certified. They know how to stage materials, protect adjacent spaces, minimize dust, and work quietly. We've done commercial glass contractor work on occupied properties throughout Denver and the metro area.
The design-build advantage: we can propose the installation sequence during design, not surprise you with it later. You can see the timeline, the crew count, and the impact before you approve it.
Wind load requirements for your building's glazing
Wind load is the most critical structural input for glazing. It determines frame size, glass thickness, sealant width, and whether you need laminated glass for safety.
Wind load depends on the building height, exposure category (urban or open terrain), design wind speed for your area, and whether the facade is on the windward or leeward side.
Denver sits in Wind Zone 1, which has lower design wind speeds than mountain passes or open plains. But a 15-story building on a ridge sees different exposure than a 3-story strip center.
During design-build, we work with the structural engineer to confirm the design wind speed and exposure. We then specify frame depth, mullion spacing, glass thickness, and sealant joint widths to meet that load.
We size Insulated Glass Units using U-value calculations, and we confirm that low-E coatings don't compromise the structural rating. SHGC (Solar Heat Gain Coefficient) also affects unit thickness on south and west exposures.
Our NACC Master-Certified glaziers can explain the tradeoffs: deeper mullions reduce sightline and cost more; thicker glass adds weight and thermal mass; structural silicone allows thinner frames but requires more precision in installation.
How to specify glass for safety glazing locations
IBC Section 2406 defines where safety glazing is required: within 24 inches of a door, in doors themselves, in low-level windows near walking surfaces, and in bathrooms.
Safety glazing means either laminated glass or tempered glass. Laminated glass stays in the frame if broken; tempered glass shatters into small, relatively harmless chunks.
For curtain wall and storefront applications, laminated is more common because it holds the seal of the Insulated Glass Unit intact. A tempered lite in an IGU can create a moisture problem if the inner seal breaks.
During design-build, we specify which lites are safety glazed. A typical curtain wall might have laminated glass in the bottom row (safety zone) and standard tempered glass above. A storefront might have all-laminated units.
We also spec the interlayer: PVB for standard safety, ionoplast for high-performance (solar control, acoustic), or specialty films for security or blast load.
Once we've locked the spec, our fabrication facility builds the IGUs with the correct lites and interlayers. Installation crews verify that the safety glass is installed in the correct orientation before sealing.
If you're working on a glass partition installation project within occupied space, safety glazing spec is especially important for interior partitions near walkways.
Related services and how they fit
Design-build glazing is often paired with other contractor services. Many projects include tenant improvement glazing on upper floors, new storefront at ground level, and interior glass partitions for office layout.
When a property manager is planning a full facade refresh, design-build handles the new curtain wall or storefront, and our warranty-phase rescue capability handles any existing glazing that needs repair during the project.
We're a commercial-only firm. We don't split focus between residential and commercial work. Every glazier on our team is trained on the systems we design and install.

Frequently Asked Questions
Design phase typically takes 4 to 8 weeks, depending on building complexity and how quickly design decisions are made. Simple projects with fixed curtain wall systems and no novel details can move in 4 weeks. Complex projects with mixed systems, custom geometry, or occupied-building logistics can take 8 to 12 weeks. Fabrication follows. Standard Insulated Glass Units take 6 to 8 weeks from order to delivery. Custom units or laminated glass can add 2 to 4 weeks. Installation then depends on the scope and scheduling constraints. Total project timeline: 3 to 6 months from initial design meeting to final installation, depending on scope and decision velocity.
Design-build does cost more upfront because you're paying for design consulting before you lock a bid. However, you recover that cost through fewer change orders, less rework, and faster installation. We've seen spec-and-bid projects hit 15 to 20 percent change orders because the spec didn't account for real-world site conditions, structural interface issues, or logistics constraints. Design-build usually comes in at less than 5 percent changes because the glazier was part of the decision from the start. If schedule matters (occupied building, fast-track GC), the timeline savings alone justify the upfront design fee.
We handle both. A small tenant improvement with new storefronts and interior glass partitions can use the same design-build process as a full facade. The principle is the same: design with accountability, then build what you designed. Smaller projects move faster through design but still benefit from structural review, code compliance confirmation, and material coordination.
Changes during fabrication cost time and money. That's why the design phase matters: we lock details before fabrication starts. If a change comes up, we assess the impact. Colour or finish changes are usually fast. Structural changes (thicker glass, different sealant, new frame depth) require redesign and re-testing. We'll tell you the cost and schedule impact upfront. Design-build catches most change drivers during design.
We are. During design-build, we specify the system, we fabricate it, and we test it before installation. If a unit fails ASTM E330, ASTM E1300, or ASTM C1394 testing, we rebuild it in our shop. The crew doesn't install a failed unit. We carry a warranty on workmanship and materials through the project closeout. Defects found during installation are our responsibility to fix.
We coordinate directly with your architect. We attend design meetings, we respond to RFIs, and we provide shop drawings for approval. Your architect maintains final authority over the design, and we execute what's approved. You stay in the loop, but we handle the technical conversation. That's what NACC certification means.
We provide a design fee upfront. The fabrication and installation price comes after design is locked, based on the final specification and quantities. Some projects use a guaranteed maximum price (GMP) model. We set a design fee and a GMP for fab and install, assuming the design stays within agreed parameters. If the design changes, the GMP adjusts. We discuss the pricing model during the initial kickoff. Transparency on cost is part of how we work.
We'll hold the fabricated units in our warehouse for a reasonable period. Exact timing depends on the unit type and storage capacity. Long delays can affect shelf life on certain sealants or coatings, so we may need to refresh units if the install pushes more than 6 to 12 months. We'll work out the logistics and cost impact. Design-build scheduling includes a buffer for this. We don't typically fabricate until framing is substantially complete and you've approved the final installation window.
Yes. We encourage it. Property managers and GCs often visit to see the units being built, confirm colour matches on anodized frames or painted mullions, and watch mock-ups of the assembly. We schedule facility visits by appointment. Your team can see the quality standard we maintain and ask questions of the fabrication crew directly.
When Glass Door Problems Can't Wait Contact Element13
Your building's glass front entrance doors handle hundreds of entries daily. When they fail, have cracked glass, broken closers, or hardware that won't engage, it's not just inconvenient, it's a security risk. Property managers and general contractors know that entrance problems reflect poorly on the entire building and create liability concerns.
