When the Parking Garage Becomes the Statement: Jakob Webnet at the Convention Center Carpark, Springfield, MA

Engineering-grade stainless steel mesh. Custom brackets. A bold identity—literally woven into the façade.

There are parking garages that blend into the streetscape. And then there’s the Convention Center Carpark in Springfield, Massachusetts.

Anchored across the street from the MassMutual Center, this multi-level facility is more than infrastructure—it’s a visual marker for one of New England’s most active convention destinations. The design brief demanded something that could span large open façade sections, contain the inherent safety requirements of an open-air garage, and carry large-format metal lettering and a logo directly on the enclosure system itself. That’s not a typical spec. That requires a mesh engineered to perform.

Jakob was called in to provide exactly that.

The Challenge: More Than Just a Safety Screen

Multi-story parking structures present a specific set of structural and aesthetic demands for any façade system. The spans between anchoring points are large. Wind loads are constant and directional. The system must retain its geometry under service loads without excessive deflection—because a sagging mesh is both an aesthetic and a safety concern.

For this project, the engineering challenge was compounded by a key architectural decision: integrating large-scale metal lettering and a logo directly onto the mesh surface. This introduced localized point loads and additional dead weight distributed unevenly across the cable network. Any system not specifically engineered for this condition would either over-deform under the added load or require so many intermediate supports that the visual openness would be compromised.

The solution required custom-engineered hardware—not catalog brackets.

Swiss Engineering Meets Pacific Northwest Waterfront

When Seattle’s Pier 58 collapsed in September 2020, the city lost more than infrastructure—it lost a beloved waterfront gathering space. Rebuilding required 600 linear feet of coastal protection that could withstand Pacific Northwest conditions while preserving the unobstructed Elliott Bay views that define this location.

Jakob’s Inviss-C frames with Webnet mesh now protect the entire coastal perimeter, delivering transparent safety barriers that visitors barely notice—while performing flawlessly in one of North America’s most demanding marine environments.

The Challenge: Protection in a Harsh Marine Environment

Seattle Parks and Recreation faced specific technical requirements:

600 linear feet of coastal protection along Elliott Bay
Transparent barriers preserving panoramic water views
Marine-grade durability for constant salt spray exposure
Seismic-rated systems for earthquake-prone region
Zero maintenance requirements for public infrastructure
Seattle Building Code compliance

Traditional railing systems struggle in these conditions. Glass requires constant cleaning in salt-spray environments and blocks natural ventilation. Powder-coated aluminum corrodes in marine exposure. Rigid systems perform poorly during seismic events.

The project demanded engineered solutions specifically designed for coastal conditions.

Jakob’s Solution: Inviss-C Frames with Webnet

Jakob supplied 600 linear feet of Inviss-C frames with Webnet mesh infill for Pier 58’s coastal-facing barriers.

Marine-Grade Material Specification
Every component is fabricated from AISI 316 stainless steel—marine-grade material used in ship construction. This specification matters in coastal environments where material choice determines long-term performance.
AISI 316 contains molybdenum, providing superior corrosion resistance compared to standard architectural stainless steel (AISI 304). In salt-spray environments, this difference determines whether a system performs for decades or requires replacement within years.

Transparent Protection
Webnet mesh provides code-compliant fall protection while maintaining visual transparency. From even a short distance, visitors see Elliott Bay—not the barrier system. The open mesh design allows natural airflow, reducing wind loads across the 600-foot installation.

Seismic Engineering

In earthquake-prone Seattle, flexibility provides structural advantage. Webnet’s flexible mesh construction absorbs seismic movement without failing. The Inviss-C frame system meets Pacific Northwest seismic codes, with each section designed to move independently during seismic events.

Installation Efficiency

Pre-engineered Inviss-C frames simplified installation and code approval processes. The modular system adapted to Pier 58’s geometry without requiring custom fabrication, supporting the project timeline.

Performance in Pacific Northwest Conditions

Since opening, the installation has demonstrated its design intent:

100% Seattle Building Code compliance achieved on first inspection
Full ADA accessibility maintained throughout

Visual Experience

Panoramic Elliott Bay views preserved across entire installation
Transparent barriers maintain sightlines from all angles
Natural ventilation through mesh reduces wind turbulence

Material Performance

Material Specification for Coastal Projects

For waterfront and coastal installations, material specification drives long-term performance.

Understanding AISI 316 Stainless Steel

AISI 316 stainless steel contains:

16-18% chromium (corrosion resistance)
10-14% nickel (structural stability)
2-3% molybdenum (marine environment protection)

This composition provides resistance to chloride corrosion—critical for salt-spray environments. Alternative materials without molybdenum content deteriorate in marine conditions.

The Scale Factor

At 600 linear feet, material specification becomes increasingly important. Systems requiring periodic maintenance create ongoing operational obligations. Marine-grade materials eliminate these requirements entirely.

For public infrastructure, this distinction affects budgeting, staffing, and long-term facility management.

Why Architects Specify Jakob for Marine Environments

Pier 58 demonstrates principles that apply to coastal projects of any scale:

True Marine-Grade Materials
We specify AISI 316 stainless steel—not “marine-rated” coatings applied over inferior base materials. The material composition itself provides corrosion resistance, not surface treatments that degrade over time.

Engineering for Transparency

Safety barriers shouldn’t dominate the visual experience. Webnet systems provide code-compliant protection while preserving view corridors—essential for projects where waterfront views create value.

Seismic Performance
Flexible mesh construction performs better than rigid systems during seismic events. For Pacific Northwest projects, this characteristic provides both structural and life-safety advantages.

Operational Simplicity

Public infrastructure managers value systems that don’t require ongoing maintenance programs. Marine-grade materials eliminate the need for inspection schedules, treatment programs, and replacement planning.

The Solution: Custom Brackets + Jakob Webnet

One bracket design wasn’t going to cover this project. The geometry changed floor to floor, the load conditions varied across the façade, and the signage attachment points needed their own solution. Jakob’s engineering team developed three bracket types — all in AISI 316 stainless — each built for a specific condition rather than a generic average.

The shared base — Groundplate Art. No. 239944 — provides a consistent, bolted anchor to the structure across all bracket configurations. From that foundation, each bracket type addresses a distinct structural need:

Bracket Type 1 (Art. No. 239948) — A dual-flap configuration with a 127 mm assembly height. Designed to receive both vertical and horizontal cable runs, distributing loads across the connection point. Total assembly weight: 1.652 kg.

Bracket Type 2 (Art. No. 239953) — A single-flap, 132 mm assembly, incorporating an M8 threaded top connection for pre-tensioning control. At 1.687 kg, it is the heaviest of the three — optimized for zones with higher load demands or specific cable pre-tension requirements.

Bracket Type 3 (Art. No. 239957) — The most compact configuration at 103.5 mm assembly height (1.561 kg), sharing the Top 2 component with Bracket Type 2. Used in locations where spatial constraints limit the bracket profile.

All three types were engineered to ISO 2768-mK general tolerances and fabricated with Ra1.6 surface finish — consistent with Jakob’s precision manufacturing standards.

Springfield winters are not gentle. Road salts, standing moisture, and hard freeze cycles are standard — and they eat through lower-grade metals over time. Specifying AISI 316 stainless for the mesh wasn’t a premium choice; it was the baseline for a system expected to perform without intervention for decades. Webnet handles those conditions without complaint. That’s the point.

Engineering for the Unexpected: The Lettering Load

One of the most technically interesting aspects of this project was the signage integration. Large-format letters spelling “CONVENTION CENTER CARPARK” — visible in the drone photography — were mounted directly to the Webnet surface.

This is not standard. Most mesh installations treat signage as a separate system. Here, the mesh had to carry the additional weight and localized load of the metal lettering while maintaining cable geometry and system stiffness within acceptable limits.

The custom bracket spacing was optimized specifically to control deflection at these load points. Pre-tensioning of the cables was a critical variable — enough tension to limit deformation under the sign weight, without overstressing the connection hardware. The three bracket types, used in combination, gave the installation team the flexibility to address varying load conditions at specific locations across the façade.

The result: a façade system that reads as effortlessly clean from the street while performing as a precision-engineered structure in the background.

Why This Matters for Architects and Engineers

The Convention Center Carpark project is a useful reference point for any design team specifying mesh enclosures in demanding conditions. Several principles from this installation apply broadly:

A few things this project makes clear for anyone specifying mesh on a similar brief.

Pre-tension gets designed in or it doesn’t work. On large spans, the cable tension determines how the system behaves under load — not just at installation, but months later when the sign weight has been sitting there through two winters. You can’t tension your way out of a problem in the field that should have been solved on paper.

Off-the-shelf brackets force compromises. When the support spacing is dictated by what’s available in a catalog, the geometry of the system follows — and not always in the direction the design intended. Three custom bracket types cost more upfront. They also mean the mesh sits exactly where it’s supposed to.

And on the signage question specifically: the weight and attachment method of the lettering had to be defined before the load analysis could run. Teams that treat signage as a construction-phase decision — rather than a design-phase input — often find themselves retrofitting solutions that should have been part of the original spec.

Why Architects and Contractors Specify Jakob

There are mesh products. And then there are mesh systems.

The difference shows up on projects like this one — where the specifications includes something nobody anticipated, like bolting large metal letters to a tensioned cable façade. It requires someone willing to model the load, design the hardware, and stand behind the result.

If your project is straightforward, most mesh suppliers can handle it. If it isn’t — if the geometry is complex, the loads are unusual, or the design intent doesn’t leave room for compromise — that’s where the engineering behind Jakob becomes the deciding factor.
