Keep the Facility Shipping and Receiving While Construction Happens Around It

Warehouse downtime costs between $5,000 and $100,000 per hour. Uncontrolled construction dust settles on product, triggers food safety violations, disables automation sensors, and creates forklift-to-worker conflicts that end careers. 5DCCS modular containment systems keep construction zones cleanly separated from active operations so the dock stays open, the racking stays in service, and the facility keeps its compliance standing throughout the project.

The Warehouse Construction Problem

Two Workforces, One Building, Completely Different Hazard Profiles

Active warehouse construction is one of the most hazardous occupied-space scenarios in construction. Construction workers drilling into concrete, running conduit overhead, or welding steel mezzanine frames are operating under OSHA 29 CFR 1926 construction standards. Warehouse employees driving forklifts, pulling pallet jacks, and moving through the same building are covered under 29 CFR 1910 general industry standards. OSHA's multi-employer worksite policy means the controlling contractor is accountable for both populations — and a forklift-to-construction-worker collision, a piece of falling hardware, or silica dust drifting into an active pick aisle creates liability that belongs to the GC.

Containment walls are the primary mechanism for keeping those two populations separated. A rigid modular barrier at the construction zone perimeter defines where construction ends and warehouse operations begin — creating a physical boundary for access control, dust control, debris containment, and forklift traffic management simultaneously. Without that boundary, the hazard environments overlap and no one can reliably control either one.

In-Plant Offices and Enclosed Work Zones

Interior Build-Outs Inside Warehouse Footprints Are a Specialty of Their Own

One of the most common warehouse construction scenarios is the in-plant office or modular enclosed workspace — a finished office, break room, supervisor station, or training room built inside the warehouse shell. These build-outs generate gypsum dust, VOC fumes from paint and floor finishes, and HVAC installation debris in a space where product is stored 20 feet away on open racking. In food, pharmaceutical, or electronics warehouses, those fumes and particulates are compliance events, not just housekeeping problems.

Our modular containment systems are well-suited for this application specifically. A clean, sealed perimeter around the build-out zone keeps construction activity contained from day one, allows adjacent aisles to remain in full operation throughout the project, and comes down at closeout without the drywall demolition debris that a conventional built-in-place office generates at the end of the lease.

Containment for Every Warehouse & Distribution Project Type

From racking installations and automation upgrades to cold storage expansion and interior office build-outs, warehouse construction covers a wide range of work types — each generating distinct hazards that require physical separation from active operations.

🏗️
Structural Work

Racking, Mezzanines & Structural Steel

Pallet rack installation requires concrete anchor drilling that generates silica dust. Mezzanine construction creates falling debris and weld spatter risks directly above active storage and pick aisles. Our containment systems create defined construction perimeters with overhead protection provisions, keeping debris and particulate off stored product while forklift traffic continues in adjacent aisles.

🤖
Automation

Conveyor, Automation & AS/RS Upgrades

Micro-dust from construction settling on optical sensors, LiDAR units, and laser guidance systems causes AGV misrouting and conveyor scanner failures in adjacent automated zones. Our sealed barrier systems prevent particulate migration into active automation environments during installation of new conveyor systems, sorters, and robotic pick infrastructure.

🏢
Interior Build-Outs

In-Plant Offices & Interior Workspace Build-Outs

Drywall, painting, electrical, HVAC, and flooring work inside warehouse footprints generates VOCs and gypsum dust that can migrate across open racking to stored product. In food, pharmaceutical, or electronics warehouses, this is a compliance event. Our containment barriers isolate build-out work from day one, with sealed top tracks that prevent VOC migration into adjacent storage zones.

🧊
Cold Storage

Cold Storage Expansion & Refrigeration Upgrades

Cold storage construction requires cutting through insulated panels and running refrigerant piping through active temperature-controlled zones — every breach risks thermal infiltration that disrupts product storage and can trigger USDA FSIS or FDA temperature compliance violations. We design containment with vapor barrier provisions and airlock vestibule configurations to maintain thermal separation during refrigeration work.

🍽️
Food Safety

Food-Grade & FSMA-Regulated Warehouse Renovation

Under 21 CFR Part 117, food warehouses must prevent physical contamination of stored product. Construction dust and debris migrating onto food or food-contact packaging materials are potential cGMP violations that can trigger FDA inspection findings. Our rigid sealed barriers provide the physical contamination control that FSMA hazard analysis requires when construction occurs adjacent to active food storage.

💡
Systems Upgrades

LED Lighting, Electrical & Sprinkler Retrofits

LED lighting upgrades require overhead drilling that drops debris directly onto product stored on racks below. Sprinkler system modifications require taking portions of the active system offline — every zone of impairment requires fire watch under NFPA 25. Our containment systems define the impairment zone, minimize the area requiring fire watch coverage, and protect product from overhead construction debris.

Regulatory Framework

The Overlapping Codes That Govern Occupied Warehouse Construction

Warehouse construction is regulated by an unusually dense stack of overlapping standards. OSHA's multi-employer worksite policy means the controlling contractor is accountable for both construction workers under 29 CFR 1926 and warehouse employees under 29 CFR 1910 — two separate regulatory frameworks that both apply simultaneously inside the same building.

For food, pharmaceutical, and cold chain warehouses, an additional layer of FDA, USDA, and Good Distribution Practice requirements applies on top of the OSHA and fire code baseline. Construction that crosses any of these regulatory lines does not just create a safety incident — it creates an inspection finding that can affect operating licenses, import alerts, or distribution contracts.

The containment barrier is often the single most important compliance mechanism on a warehouse construction project: it separates the regulated storage environment from the uncontrolled construction zone, limits the area of fire suppression impairment, creates the forklift exclusion zone, and provides the physical contamination control that FSMA hazard analysis requires.

OSHA Multi-Employer Worksite Policy The controlling contractor is responsible for protecting both construction workers (29 CFR 1926) and warehouse employees (29 CFR 1910) from each other's hazard environments. Physical containment is the primary mechanism for maintaining that separation.
29 CFR 1910.178 — Powered Industrial Trucks Forklifts cause approximately 85 deaths and 34,900 serious injuries annually. Adequate safe clearances must be maintained in all aisles and through all doorways. Construction activity cannot reduce forklift aisle clearances; physical barriers defining construction zone perimeters are the primary compliance mechanism.
NFPA 241 — Construction Fire Safety Requires a written Fire Safety Program and designated Fire Prevention Program Manager for all occupied building construction. Between 2010 and 2014, construction site fires caused an average of $300 million in annual property damage. Containment walls limit fire spread risk and define impairment zones.
NFPA 13 / NFPA 25 — Sprinkler Systems Temporary barriers must not obstruct sprinkler head spray patterns. When sprinkler systems are impaired for more than 10 hours in a 24-hour period, continuous fire watch is required under NFPA 25 Section 15.5.2. Containment walls limit the impaired zone and reduce fire watch cost and duration.
FDA 21 CFR Part 117 — FSMA Food Safety Food warehouses must prevent physical contamination of stored product and food-contact packaging. Construction dust and debris migrating into active food storage are potential cGMP violations. Containment barriers provide the physical hazard control that FSMA risk-based preventive controls require during adjacent construction.
USP <1079.4> — Pharmaceutical Cold Chain Construction projects that alter warehouse layouts, HVAC systems, or refrigeration equipment trigger a temperature mapping re-qualification obligation for pharmaceutical storage facilities. Containment systems that limit construction impact on HVAC configuration help minimize the scope of re-qualification required.

What Warehouses Need That Plastic Sheeting Cannot Provide

Plastic sheeting is inexpensive, tears under forklift air blast and HVAC pressure, provides no acoustic attenuation, fails fire code in egress paths, and leaves dust settling on product the moment a section gaps. Here is what modular walls provide in a warehouse environment.

Rigid Structure That Holds Against Forklift Air Blast and HVAC Pressure

Active warehouses run constant HVAC airflow and forklift traffic that generates significant air movement near barriers. Plastic sheeting billows, tears, and gaps under these conditions. Our rigid panel systems maintain sealed perimeters throughout the project duration without daily re-taping or patching.

🍽️

Physical Contamination Control for FSMA and cGMP Compliance

Food, pharmaceutical, and electronics warehouses need barriers that genuinely prevent dust and particulate from reaching stored product. Our sealed panel systems with floor-to-ceiling tracks provide the physical contamination control that 21 CFR Part 117 hazard analysis and cGMP requirements call for adjacent to active food and pharmaceutical storage.

🔥

ASTM E84 Class A Fire Rating in High-Combustible Environments

Warehouses store combustible goods. Barriers in occupied warehouses must meet ASTM E84 Class A fire rating — the standard required in egress paths and near high-combustibility storage. All panels in our systems are Class A rated, eliminating a common compliance gap that plastic sheeting creates in warehouses with active fire suppression systems.

Same-Day Installation Without Disrupting Receiving or Shipping Operations

Our installation generates zero cutting dust and zero debris — critical when the floor 10 feet away is active pick-and-pack or receiving. Most standard warehouse configurations install in a single day, so the construction zone is sealed and forklift traffic in adjacent aisles is protected before the construction crew's first tool lands on the concrete.

🔄

Reconfigurable as Construction Phases Advance Through the Building

Warehouse renovations that move zone by zone — racking row by racking row, or bay by bay for LED upgrades — need containment that relocates without a full rebuild. We reconfigure without demolition, keeping the construction footprint tightly controlled as phases advance and minimizing the area of operation that is impacted at any given time.

Yes — and it is usually the only viable option given the cost of downtime. Warehouse downtime costs range from $5,000 to $100,000 per hour depending on facility type, automation level, and service level agreement obligations. With proper containment, active racking, pick operations, and dock functions in adjacent zones can continue throughout renovation. The construction boundary is the key: once a rigid sealed barrier defines the construction zone, both populations — construction crew and warehouse staff — know exactly where the safe work boundary is, and operations on the other side of the wall proceed normally.
Forklift-to-construction-worker conflicts are one of the leading hazard categories in occupied warehouse construction. OSHA 29 CFR 1910.178 requires that adequate safe clearances be maintained in all aisles and doorways — a standard that construction activity frequently compromises when work zones are not clearly demarcated. Our rigid modular barriers create a visible, solid perimeter that forklift operators can see and recognize as a boundary, unlike plastic sheeting that can be difficult to distinguish from surrounding materials in a busy warehouse environment. We design barrier layouts that account for forklift turning radius requirements and OSHA minimum aisle clearances at the initial design stage.
Under FDA 21 CFR Part 117 and FSMA, food warehouses must prevent physical contamination of stored product and food-contact packaging materials. Construction dust, debris, and condensate reaching stored food or its packaging are potential cGMP violations that can trigger FDA inspection findings and enforcement actions. Our sealed rigid panel systems provide the physical contamination control that FSMA hazard analysis requires when construction occurs adjacent to active food storage. We can provide barrier system specifications to your food safety team for inclusion in the facility's construction-period hazard analysis documentation.
Yes, though cold storage adjacency requires additional design considerations beyond standard warehouse containment. The primary concerns are thermal infiltration — warm construction air entering the cold zone through barrier gaps or worker ingress — and condensation on panel surfaces where warm humid air contacts cold panel faces. We design cold storage barrier configurations with sealed base and top tracks, vapor barrier provisions at panel joints, and airlock vestibule options for high-frequency construction worker entry. For USDA FSIS-inspected facilities, we can provide system documentation that supports your temperature excursion prevention plan.
This is a critical design consideration that we address at the layout stage. NFPA 13 requires that sprinkler spray patterns not be materially obstructed by temporary barriers — if a barrier exceeds the height at which it would shadow a sprinkler head, additional sprinkler coverage may be required in that zone. We review sprinkler head locations and design barrier heights that maintain compliant coverage or flag the need for additional heads to your fire protection engineer before installation. Containment walls also help by limiting the zone of sprinkler system impairment during modification work, which reduces the area requiring continuous fire watch coverage under NFPA 25.
Yes. Active warehouses often run significant HVAC airflow, evaporative coolers, and large overhead fans that create sustained air pressure differentials across any barrier in the space. Plastic sheeting billows, tears, and gaps under these conditions — often within days of installation. Our rigid modular panel systems are structurally stable under sustained air pressure and do not require re-anchoring or patching as conditions change. Floor tracks provide the base seal and ceiling connectors or braced top tracks maintain the upper seal throughout the project.
Yes. Full-service rental includes delivery, installation, reconfiguration as phases advance, and removal at project completion. Self-service rental is available for facilities or GCs with in-house installation capability. System purchase is worth evaluating for large distribution center operators, 3PLs, or GCs managing ongoing construction programs across multiple warehouse facilities — the per-project economics improve substantially once the inventory is owned, and the deployment speed increases significantly when panels are already on-site and ready to configure for the next project phase.
