IN THE FACTORY AND ON SITE
ShellForm™ System highlights
Industrializing the physical delivery workflow of cast-in-place reinforced concrete through the ShellForm™ System
Structural system and code path remain unchanged
A reinforced-concrete building can be replicated locally, but it cannot go global as the same product: it answers to its codes, its climate, its structural conditions, its approval path, and the chain of engineering responsibility behind it.
What repeats in every market is not the building. It is the delivery workflow behind it. Market after market, cast-in-place reinforced concrete repeats the same site work: temporary support, formwork, reinforcement placement, embedded items and MEP coordination, concrete placement and curing, stripping, insulation, plastering and finishes. That recurring delivery workflow is the true unit of industrialization for reinforced concrete.
We founded ShellForm Technologies to industrialize it: we keep the design, the code path, the approvals and responsibility chain, and the site-cast structural core local, and turn the repeatable site work behind the building into an industrialized product system that adapts to each market.
Shear walls, columns, beams, slabs, and partitions in one system; L-, T-, U-shaped corners and straights, one assembly family.
Formwork function, reinforcement positioning & integration, conduits & boxes, embeds, insulation boards, and plaster & decorative finishes, integrated in one factory pass.
Members arrive with reinforcement and every layer already integrated. On site they connect by lap splices or mechanical couplers, below, above, and side to side, to each other or to conventional cast-in-place work.
Walls, columns, beams, and slabs are placed one after another; all members set, then the whole floor is cast as one continuous placement. The structural concrete is conventional and placed entirely on site, encasing the pre-installed reinforcement to form one monolithic structure. Structural system and code path remain unchanged.
ShellForm Technologies Inc., headquartered in the US, industrializes the delivery workflow of cast-in-place reinforced concrete, turning multi-trade site work into a product system.
Non-structural, stay-in-place ShellForm™ assemblies pre-integrate reinforcement cages, connectors, insulation, conduits and boxes, the finish substrate, and, where specified, decorative finishes. The monolithic site-cast structural core and its code path remain unchanged.
A decade of deployment in the system's market of origin, with 1,000,000+ m² of GFA delivered, backed by proprietary technology, an industry technical standard, and industry recognition.
Pilot projects open each market, and production capacity is qualified through the route each market requires. Delivery runs through market-qualified capacity.
For most of the world’s cast-in-place reinforced concrete, delivery is not yet industrialized at scale: formwork, rebar, embeds, insulation, and plaster still arrive as separate trades, sequenced, coordinated, and executed largely by hand on site. The ShellForm™ System moves those repeatable trades into the factory as hollow, stay-in-place assemblies, while the load-bearing core is still cast monolithically on site.
Structural continuity between assemblies, and with conventional cast-in-place or other systems, follows the project’s structural design and applicable codes. Scope: occupied building structures such as residential, hospitality, affordable housing, and public buildings; steel and timber framing follow their own paths.
Reinforced concrete is one of the world's dominant building structures, and most of it is still cast in place on site. The delivery workflow behind it has barely industrialized while the workforce that executes it is shrinking.
The addressable market is not a share of modular or precast construction.
It is the delivery workflow of cast-in-place reinforced concrete itself, work that recurs on every project, every year.

Digital tools, BIM, and single-task robots improve isolated steps, but the site stays a sequential, multi-trade workflow.
Repeatable delivery operations move into industrialized factory production; site work narrows to component setting, continuity connections, and concrete placement.
Formwork and low-integration stay-in-place systems preserve the cast-in-place structure but stop at formwork or the insulation board.
Factory assemblies add reinforcement integration, embeds, insulation board, and plaster and decorative finishes, moving repeatable trade content into standardized, industrialized batch production.
Heavy factory-made structural products narrow the project pool through weight, transport radius, lifting limits, local-code acceptance, below-grade constraints, and plant-utilization economics.
Hollow ShellForm™ assemblies ship light while the load-bearing core is cast locally, allowing broader use across applicable reinforced-concrete scopes, from walls and corners to basement and foundation applications.

The bottleneck in industrializing reinforced-concrete construction is not software, robotics, or factory scale alone; it is whether the repeatable work that constrains field execution can be shifted into industrialized factory production without turning the structure itself into a factory product.
Repeatable site work moves into factory-integrated stay-in-place ShellForm™ assemblies, while the reinforced-concrete structural core remains site-cast and monolithic.

Highlighted in the model: the cementitious composite panels and the galvanized steel connectors. Both are excluded from the structural calculation and carry no structural load. The reinforcement cage arrives factory pre-installed; the load is carried by the cage and the structural concrete, cast entirely on site, forming one monolithic structure.
ShellForm™ assemblies cover conventional cast-in-place reinforced-concrete structural systems, including shear wall, frame-shear wall, and frame-core tube configurations. Member geometries shown are representative;
final assemblies are configured to the project structural design.
The core hollow stay-in-place wall assembly: interior and exterior cementitious composite panels, galvanized steel connectors, a pre-positioned reinforcement cage, and an open cavity for on-site structural concrete placement.
The same wall and column assemblies extend directly into foundations: strip footings, isolated footings, and continuous basement walls, from villas to commercial and industrial buildings.
Large isolated footings, strip footings, and continuous basement walls; most valuable where excavation faces require vertical formwork, shoring, reinforcement tying, or column-base integration.
Wall and column-base assemblies are positioned together; wall panels carry graded flow openings so concrete can flow into the connected cavities and fill them uniformly.
Hollow factory-made shells weigh a fraction of solid precast foundation units, easing transport, lifting, and installation; the footing is completed as one cast-in-place pour, without heavy precast-to-precast connections.
Reduces scaffolding and on-site formwork setup along excavation faces, so the schedule benefit begins at the foundation and carries through the project.
Example configuration shown: a 4.0 × 4.0 m footing, 0.5 m deep, supporting an 840 mm column; dimensions are project-determined, not a system limit. Factory-produced cementitious composite panel faces and galvanized steel connectors are non-structural; the load path is the field-placed reinforcement plus site-cast concrete.
Shown on a wall assembly as the illustrative case; the same thermal, finish, and façade-interface modules apply across the member family, configured to each project.
Modules are selected by requirements; the site-cast reinforced-concrete structural core remains unchanged.
Shown as a wall: interior and exterior cementitious composite panels, galvanized steel connectors, a pre-positioned reinforcement cage, an open cavity for the structural pour, and embedded conduits and boxes where required.
Full-length insulation connectors are set into the still-wet panels on both sides of the board and extend into the structural cavity, encased by the site-cast concrete. This concrete encasement greatly reduces the debonding risk of conventional external insulation.
Factory coating or paint, textured formliner, reverse-cast veneer in tile, stone, brick, or porcelain, and embedded façade or PV inserts, all integrated during factory panel production or at a factory finishing station.
20 mm standard in current deployments; oversized members can be upsized to 25 mm or more where needed; 12 mm validated in controlled testing, deployment pending
Equals the structural wall thickness per design; the cavity is the cast-in-place structural core
The proprietary cementitious composite panel resists the fresh-concrete pour, stays permanently in place as the plaster and finish base, and carries no structural load. This dual role is the core of the ShellForm™ System.
Non-structural stay-in-place panel faces resist fresh-concrete lateral pressure during the on-site structural pour, then stay permanently in place as the plaster and finish substrate; the panels are excluded from the structural calculation.
Supports on-site pours up to 6 m, placed in conventional lifts. Panels and galvanized steel connectors form an integrated system; panel thickness and connector spacing tune to the design pour.
The formulation incorporates 50 to 70% low-carbon constituents, and the permanent panels remove the need for separate reusable timber or aluminum formwork, cutting on-site material cycling and waste.
In-house automated production of the proprietary cementitious composite dry mix, pre-batched to specification and supplied in 1.5-tonne bulk bags, with an installed design capacity of 1,200 tonnes per day; fibers and admixtures are supplied separately and dosed at mixing, when the dry mix is combined with water at the assembly facility.
Each connector is a thin, flat galvanized steel strip. Its length matches the cavity dimension of each specific assembly, and lengths range across the product family to accommodate all member types.
Each connector spans panel face to panel face, standing vertically on its thin edge, in the same plane as the transverse reinforcement, so concrete placement and vibrator consolidation are not obstructed.
Spacing is denser in the lower zone of each member to resist higher fresh-concrete lateral pressure; standard spacing applies in the upper zone, set per the structural design and quality-control program.
Connectors tie the panel faces only and make no contact with the reinforcement cage, which is positioned independently by plastic rebar spacers embedded during factory panel production.
A proprietary reconfigurable assembly fixture integrates the reinforcement cage, connectors, electrical boxes, insulation board, embeds, and optional modules, so both panel faces and the integrated cage form in one wet-state sequence before a single factory cure.
Adjusts height, width, cavity depth, and panel thickness for project-specific assemblies, without fixed molds.
Reinforcement cage, galvanized steel connectors, embeds, and optional modules, highly integrated in the offline-preloaded assembly fixture.
Cast on the mold table.
The offline-preloaded assembly fixture, carrying the reinforcement cage, connectors, and embeds, is positioned onto the wet first panel.
For insulated assemblies, the insulation board and full-length insulation connectors are placed after the first face, set into the still-wet panel.
Cast onto the assembly fixture, completing both faces in one wet-state sequence.
One cure cycle for the whole assembly; no flipping.
Vacuum-lifter demolding; the assembly fixture and mold table return to the cycle.
One size per dedicated mold; cast a solid load-bearing member, steam cure, demold.
Cast and cure the first shell, cast the second, turn the first 180° onto it, then cure both.
Both panel faces and the integrated cage form in one sequence on the highly-integrated assembly fixture.
In solid precast and double-wall, the precast members are themselves load-bearing; in the ShellForm™ System the panels, connectors, and embeds are excluded from the structural calculation; the load is carried by the reinforcement cage and the site-cast structural concrete, forming one monolithic structure.
Cure-cycle figures compare straight shear-wall production.
Held at cover. Rebar spacers, cast into the wet panel, hold the pre-positioned cage at its specified concrete cover. The cage and the galvanized steel connectors are separate systems: the connectors tie the panel faces and maintain cavity geometry, with no contact with the rebar.
Placed to pull out. Horizontal connection bars are laid in and wire-tied at the factory; on site, once members are erected, the bars draw out to lap with the adjacent member.
Turned by the upender. An oversize assembly is repositioned on the assembly upender ahead of transport; connector spacing and the internal build-up read clearly in section.
Clean steel for the voyage. Laser rust removal on the projecting bars before container packing for sea freight.
A rehearsal, not a production step. Factory trial assembly ahead of an overseas shipment: tight butt joints on the outer face, hand-hole access on the inner face for the rebar connections, with fixing holes alongside for the hand-hole closures. Carried out for the first overseas shipment, verifying fit and tolerances before dispatch.
Partner and local scope by design: ordinary reinforcement, ready-mix structural concrete, and commodity materials are sourced locally.
Production lines may be configured as fixed or traveling mold-table systems and may run single or mixed assembly types, with the highest throughput achieved when focused on a single product family; actual output depends on facility layout, product mix, shifts, utilization, and market demand. Figures are calculated from a fixed mold-table reference deployment optimized for shear wall production under a 300-day reference operating schedule, with each assembly estimated at 1.8 m³ (2.5 m wide × 3 m high × 0.24 m thick).
Hollow assemblies ship before concrete is placed, so structural scope moves on standard trucks and standard cranes rather than oversize logistics.
A typical 3 × 3 × 0.2 m wall assembly weighs under 1 tonne, roughly one-fifth to one-sixth of an equivalent solid element; a standard light-duty crane handles it.
The economical road radius runs roughly 500 to 1,000 km [300 to 600 mi] from the production facility, several times that of solid precast; delivered projects have shipped roughly 800 to 1,300 km by road.
Because the structural design and code path stay conventional cast-in-place, distance does not break compliance: reinforcement is integrated to the project’s structural design under the local code, insulation and finishes follow the design’s own specification, and only the concrete is placed on site. Long reach also concentrates production: one qualified base can serve many markets before local capacity is justified.
For overseas delivery, assemblies load into standard open-top containers at the factory; the first European pilot project shipped this way, roughly 16,000 km from the production base.
Rebar is connected by conventional lap splicing or mechanical couplers per project structural design and applicable code, and structural concrete is placed per design. The finished reinforced-concrete core is monolithic cast-in-place, indistinguishable from conventional RC construction.
Formwork, form ties, plastering, insulation, MEP embedment, and decorative finishes where specified are already in place when the assembly arrives. Fewer site trades translate to shorter schedule, reduced site overheads, and less construction waste; the same crews deliver more project throughput.
A typical 3 × 3 × 0.2 m shear wall assembly weighs under 1 tonne, roughly one-fifth to one-sixth of an equivalent solid wall. A standard light-duty crane and a 3-person crew can handle installation in typical site conditions.
Light hollow assemblies arrive by standard truck; no oversize logistics or special permits.
Snap layout lines on the base slab; verify and adjust pre-installed starter bars to align with the assembly cavity before the lift.
Standard light-duty crane, assembly under 1 tonne; a 3-person crew sets each shear wall in minutes, with four adjustable diagonal braces.
Rebar continuity through lap splicing or mechanical couplers, per project structural design and applicable code, depending on member type.
Adjustable diagonal braces align each assembly to vertical and horizontal tolerances; beams and slabs use temporary props, likewise removed after the pour.
Base mortar seal; venting and rebar positioning verified before concrete placement.
Project-specified structural concrete is placed and vibrated by conventional methods; pours above 3 m proceed in multiple lifts. Once cured, the core is monolithic cast-in-place, and the panel faces remain as the finish-ready substrate.
The construction workflow is industrialized; the structural method is unchanged. From the ShellForm™ System installation model. Connection type, splice parameters, and joint schemes follow each project’s structural design and applicable code.
Excavation and base-slab casting come first; installation starts on the finished base. The base shown is illustrative: the same assemblies extend into foundations, strip footings, isolated footings, and continuous basement walls (see Below grade).
A wall member is lowered onto its starter bars; a worker torques the mechanical couplers at the base. Vertical bars connect by mechanical couplers or by lap splices, with the connection type and the associated reinforcement detailing per the structural design and the governing code; the footage shows the coupler method. Four adjustable braces plumb and hold each member, no scaffolding, and come off the day after the pour.
Between adjacent members, horizontal connection bars are tied on site at the joint; splice lengths and the associated reinforcement detailing follow the structural design and the governing code. The outer joint takes a PE backer rod and sealant; the inner gap closes with aluminum forms. The arrangement shown is one of several accepted schemes; joint methods differ in the site precision they demand, and the selection is matched to project conditions and crew capability, confirmed by the responsible structural engineer.
Shaped members, T, L, corner, follow the same rule: vertical connections to the starter bars below, horizontal connections to each adjacent member. Shown: an integral corner assembly making both connections at once.
Columns follow the same rule: vertical bars connect by mechanical couplers or by lap splices; the coupler configuration is shown here.
Walls and columns are placed one after another across the floor. Hand-hole openings at splice points close with aluminum forms once connections are complete.
Adjustable steel props are erected first. Beam assemblies are lowered level onto the props; top bars are threaded and tied on site, beam by beam.
Slab assemblies rest on point supports: adjustable props, not full shoring or scaffolding. Slab rebar is tied on site into beams and walls. Shown: the single-shell configuration; a wall-type slab configuration also exists.
One pour, two views. Right: the whole floor cast monolithically, walls, beams, slabs, and columns together. Left: the same pour seen inside the wall, placed and vibrated like any cast-in-place pour.
All members set, cast, and cured; then the floor above begins. A 3-person crew; 3 to 4 days per floor, one cycle repeating upward.
A hollow stay-in-place assembly is lifted into position, braced, and connected, with formwork function, ties, rebar, and embeds already inside. Complete procedures are documented in the ShellForm™ System technical video.
Non-structural panel faces can be locally modified for project design changes; for MEP changes the panels can be freely cut and patched by conventional methods, without altering the structural load path.
Open cavities keep reinforcement and embeds visible: bar specifications, spacing, and cover, lap splices or mechanical couplers, conduits and boxes, and insulation can all be inspected before the structural pour.
Where required, the cast-in-place structure itself can be inspected and verified through infrared thermal imaging, core sampling, and localized panel opening, under applicable approval documents and engineer-of-record specifications.
Panel and core share the same cementitious chemistry, anchored by the dense connector grid; panels are inorganic and non-combustible.
Every assembly leaves the factory with a QR identity tag. One scan resolves the component’s own record: what it is, where it belongs on the plan, and exactly what went into it.
SHELLFORM™ SYSTEM
Each delivered assembly carries a QR tag tied to its component ID. The tag resolves to a live record: member type, dimensions, floor, and its highlighted position on the layout plan.
The record carries the component’s own quantities: reinforcement, cementitious panel material, insulation board, steel and insulation connectors, and decorative finish. Material accounting is component-level, drawn from production data, rather than estimated across the pour.
Production QA data links to the same record, and key inputs carry their own certificates: reinforcement mill certificates to the specified grade, CE documentation where the market requires it, tracked to batch and producer. Conformity documentation is added as evaluation programs complete. One scan, the component’s full story.
The panel formulation incorporates 50 to 70% low-carbon constituents, and the permanent panels remove separate reusable formwork from the site. Because every component carries its own material record, material and embodied-carbon accounting can run at component level, and the same record structure is built to carry the documentation that follows. Reduced site waste, traceable materials, and trackable carbon data support LCA, EPD, and LEED documentation.
Specimen shown with masked identifiers and quantities; live records are issued per project. Deployed on the first European pilot project, now shipped and in transit.
ShellForm does not require its own structural design regime the way conventional precast does. The locally approved cast-in-place design is used as issued; assemblies are simply production divisions of that design, split by parameters every concrete code already defines.
The structure is first redesigned under the local precast code: panel joints become structural connections, seismic equivalence is proven case by case, and the system locks in early design. The conversion repeats for every project and market.
Assembly boundaries are production divisions, not structural joints; the monolithic load path is untouched. Split rules reduce to lap lengths, cover, and spacing, parameters every concrete code already defines, so the same engine ports across jurisdictions by loading the matching parameters, with no redesign loop between issued drawings and production. The system adds the delivery layer onto the issued design: cementitious composite panels, connectors, and embeds are generated by rule, and insulation follows the design’s own specification.

Numbered components; structure unchanged
Panels, connectors, and embeds configured per assembly
Process-step drawings and bill of materials, generated per assembly
Produced to specification, QR-traced to batches and QA records
Because the load-bearing structural path remains conventional cast-in-place reinforced concrete, applicability is driven less by building type than by project delivery conditions. Advantage concentrates where these press hardest, and compounds with each added floor.
Repeatable site trades move into the factory, supporting fixed handover dates.
Reduced dependence on site trades where skilled labor is scarce.
The cast-in-place core follows conventional RC code logic; delivered at scale in zones up to 0.30g.
Light hollow assemblies ease long-distance and constrained transport by standard truck.
Less laydown and site work, reducing traffic, noise, and dust pressure on tight sites.
Factory-prepped assemblies reduce weather-exposed site work in rain, heat, and cold.
Repeatable layouts industrialize fastest; benefits compound with volume.
Reduced site waste, traceable materials, and trackable carbon data support LCA, EPD, and LEED documentation.
Derived from delivered-project data; indicative ranges versus conventional cast-in-place baselines for main structural works. Outcomes vary by building type, height, local labor structure, assembly scope, and adoption scope. Validate project economics with local contractors.
Existing approaches face a fundamental trade-off: the deeper their factory integration, the further they move from conventional cast-in-place structural design and code. The ShellForm™ System resolves this trade-off.
Timber, steel, and aluminum systems keep the cast-in-place structure but stop at the formwork step. Non-structural permanent formwork, such as ICF and panel-based systems, adds insulation or a panel face, but reinforcement and MEP remain site trades; the site stays a sequential multi-trade workflow.
Structural stay-in-place and solid precast products integrate deeper, but the factory product becomes load-bearing: heavier logistics, joint design, and system-specific code acceptance.
Whole-room modules carry the most factory content, with oversize logistics, heavy cranage, and system-specific approval frameworks.
Deep factory integration while preserving the cast-in-place load path, standard reinforced-concrete code, and open pre-pour inspection.

Load-bearing prefabrication cannot hold inventory; hollow, non-structural units can. The system makes stock possible for a category that never had it. Where scopes are standardized and repetitive, stock applies; elsewhere, members are produced to project design.
In conventional prefabrication every factory unit is structure itself, engineered for a single project; elements cannot be cut, recombined, or reassigned, and cannot be held as general, reusable stock.
ShellForm™ assemblies are hollow shells that carry no structural load; the load-bearing structure is formed on site. The factory-integrated cage uses distributed reinforcement standardized per unit length, so units can be cut and recombined within defined rules, with cut lines clear of connectors, without changing the structural basis.
The stock model applies to standardized, repetitive scopes; project-specific members and engineered geometries are produced to project design, not from stock.
Corners set the shape. L- and T-corner assemblies are supplied standard and never cut.
Straights set the length. Straights are mass-produced in modular dimensions and installed at full length, with only the last closing unit of each wall cut to the remaining dimension.
Pre-formed positions. Standard units carry pre-formed lifting, bracing, and conduit and box positions.
Configured at regional points. Some are stocked without pre-set openings and configured to project design at regional processing points.
Cost items are removed from site scope, shifted into the factory, added as system costs, or left unchanged by design. Fewer site operations and coordination interfaces lower site-management burden and overheads; factory QA reduces rework and tolerance variance.

Qualitative framework. Specific unit economics vary by market, scope, and partnership tier.
ShellForm-supplied assemblies support first projects, references, and approval pathways; early market entry proceeds without committed plant investment.
Market partners hold and configure territory inventory, building customer access and repeatable demand; stock turnover becomes the demand signal for capacity.
Additional ShellForm-qualified capacity, including expanded supply from the established production base, where logistics and economics support the market.
Operating component factories add a ShellForm-qualified product line; plant and operations investment remains with the partner.
New dedicated capacity, located where market volume, logistics, and regional coverage justify dedicated investment.
Underutilized industrial assets transformed into ShellForm-qualified production at lower capital cost.
Brand-use license, factory qualification, quality-control program, certification listing, proprietary material and equipment supply, assembly fixture leasing, software and data reporting, and audit; territory, stocking, and production rights are granted separately, staged with market development.
IP, certifications, core technology, and data. Ordinary ready-mix concrete, reinforcement, and commodity materials stay local by design. Evaluations and certifications are held by ShellForm Technologies, and qualified partner factories produce as listed locations under them.
Test data, engineering analysis, and the factory QA backbone form one evidence base; one coordinated multi-standard test campaign feeds all target markets.
The same evidence base converts into each market's conformity document; ShellForm Technologies Inc. is the report holder in each pathway, and partner factories are listed locations under it.
Plants join by audit, not re-testing; once qualified, a partner plant is added to the reports as a listed location, and the technical file remains the holder's property. Where no formal product-evaluation pathway exists, the ShellForm™ enterprise standard governs quality and traceability.
