  • 150 Modular Units Delivered for a Mining Infrastructure Project in Chile: A Case Study
    Nov 03, 2026
    Wanbang Modular Building achieved a milestone with 150 Modular Units Delivered for a mining infrastructure project in Chile. Four enablers made this delivery possible: early planning, purpose-built modular design, coordinated logistics, and disciplined installation. The scope covered auxiliary-service modules for water treatment, potable water supply, and electrical power generation. These 150 integrated housing units supported an award-winning workforce housing project tied to a power transmission scheme. The outcome was clear. All units arrived on schedule, installation proceeded successfully, and the auxiliary services reached operational readiness. This modular camp project case study shows how careful coordination turns remote-site complexity into a predictable, repeatable process—and demonstrates what 150 Modular Units Delivered truly means in practice. Key Takeaways Plan early to reduce risks in remote mining projects. Design modules for easy transport and quick assembly. Coordinate logistics carefully to keep deliveries on schedule. Follow disciplined installation and quality checks for success. Mining Project Requirements in the Chile Project Auxiliary Services Scope The Chile project required three auxiliary-service streams: a water treatment plant, a potable water supply, and electrical power generation. These modules served an award-winning workforce accommodation camp tied to a power transmission scheme. Each stream had to operate independently in a remote setting with minimal operator involvement. Water treatment design followed the constraints typical of remote mining camps. Containerized plants scale from 5 to 100 m³ per day, serving roughly 50 to 1,000 people, and horizontal scaling adds parallel containers as camp population grows. Membrane bioreactor technology achieves more than 98% BOD₅ removal with total suspended solids below 5 mg/L, and automatic PLC control monitors pH, dissolved oxygen, and flow. Factory pre-testing shortens commissioning on site. Design Consideration Project Detail Treatment technology MBR and MBBR with automatic PLC control Capacity scaling 5–100 m³/day per container; parallel units as needed Durability Marine-grade C5-M epoxy or 304/316L stainless steel; insulated walls rated -40°C to +50°C Environmental compliance Meets WHO and local discharge standards; effluent suitable for dust control Footprint About 30 m² for a 50 m³/day unit Atacama Desert Site Conditions The Atacama Desert imposes extreme aridity, wide daily temperature swings, and intense UV radiation. Humidity stays below 1% year-round, and rainfall totals only 10–50 mm in the wet season. Daytime temperatures reach 30–35°C in summer, while winter nights fall to 0–10°C. The El Teniente copper mine and other Chile copper mines operate in comparable high-altitude terrain, so the camp design borrowed proven cold-climate features. These conditions shaped the specification. Walls carry insulated sandwich panels, and windows use thermal-break aluminum glazing to hold interior temperatures through the nightly swing. Sealed envelopes keep dust out. Modular construction suits this environment well: factory-built mining camp modular buildings arrive complete, and site work stays short despite the remote Atacama location. Explore modular houses designed for workforce accommodation and remote project camps. Modular Solution for the Power Transmission Camp Wanbang Modular Building served as the integrated modular construction provider for this power transmission camp. The company brings more than 14 years of experience, five production bases, and 120,000 m² of production area. Its ISO 9001, ISO 14001, and ISO 45001 certifications and CE marking support international project compliance. End-to-end service runs from camp design through production, shipping, installation guidance, and after-sales technical support. Unit Types and Specifications The project drew on four product families. Flat pack container houses ship as components and assemble on site. Folding container houses unfold quickly for immediate use. Expandable container houses offer the largest floor area per shipped unit, and modular office buildings cover administration and site functions. The 40ft expandable model illustrates the engineering behind these modular housing solutions. Specification Value Expanded size (L×W×H) 11,800 × 6,300 × 2,480 mm Folded size (L×W×H) 11,800 × 2,200 × 2,480 mm Total area 74.3 m² Unit weight 6,000 kg Structure Galvanized steel frame with folding expansion system Loading One unit per 40HQ container Layout options include one-bed, two-to-three-bed, and four-bed configurations with living, kitchen, and bath. Pre-installed wiring, sockets, and LED lights meet AU, US, EU, or UK standards. For projects that need more living space from a compact shipping footprint, expandable container houses offer another modular accommodation option. Design for Transport and Assembly Factory prefabrication drives the transport strategy. Flat-packed units ship walls, roofs, and interiors as stacked components rather than assembled volumes, which cuts the space each house occupies. Compact disassembly lets several houses travel in a single load on standard trucks and containers. Folding frames reduce width to 2,200 mm when closed, so each expandable unit fits a 40HQ container. These choices support custom quick-assembly flat-pack units and quick-assembly flat-pack units alike. On-site expansion of an expandable unit completes within hours. Galvanized steel frames resist corrosion in the Atacama environment. Standardized connections simplify lifting and joining in remote terrain, and this discipline in modular housing engineering keeps site labor predictable. The same approach serves accommodation camps across mining and engineering, procurement, and construction projects. For compact shipping and rapid deployment, foldable houses are also suitable for projects with demanding transport requirements. Delivery Logistics to the Atacama Site Route and Port Coordination Factory-to-port-to-site planning started long before the first container left the yard. Wanbang mapped the route from its production bases to a Chilean port, then onward by truck to the Atacama region. Northern ports serve mining cargo best. The team weighed each option against the final overland leg. Antofagasta (CLANF): a northern port serving the Antofagasta mining region, handling general cargo, project cargo, and concentrate exports. Mejillones (CLMJS): a northern port complex near Antofagasta used for mining inputs, containers, and bulk cargo. Iquique (CLIQQ): a northern port in the Tarapacá region, next to the Iquique free trade zone (ZOFRI). Arica (CLARI): the northernmost port, carrying a large share of Bolivian transit cargo. San Antonio (CLSAI) and Valparaíso (CLVAP): Chile's main and second container ports in the central region. Chile has state-owned ports, private ports open to public use, and private ports for private use, which are mostly terminals used by the mining sector. Customs clearance shaped the shipping schedule as much as vessel bookings did. A local importer had to appear on the documentation, and every declaration passed through a licensed customs broker under the Customs Ordinance. The team aligned the commercial invoice with the customs declaration and matched the packing list to the declared contents. Accurate HS classification prevented duty reassessments. Telecom-enabled equipment needed SUBTEL type approval before loading, so certification checks ran before departure. Category Requirement Detail Documentation Commercial invoice Must align with the customs declaration Documentation Packing list Must match declared contents exactly Documentation Transport document Air waybill or bill of lading Documentation HS classification data Inaccurate codes trigger duty disputes Documentation SUBTEL type approval Required for Wi-Fi, Bluetooth, or cellular devices Documentation Chilean importer Foreign firms use an Importer of Record Procedure Licensed customs broker Legally required for all declarations Procedure Pre-shipment compliance HS review, SUBTEL mapping, document alignment Sequencing 150 Units Volume control began at the factory. Factory prefabrication let the team ship walls, roofs, and interiors as stacked components instead of assembled volumes. Folding frames closed to 2,200 mm in width, so each expandable unit fit a single 40HQ container. This prefabrication strategy cut the shipping footprint across the whole order. The 150 units moved in staged waves rather than one block. Early vessels carried water treatment and power generation modules, which needed the longest commissioning window. Housing units followed in sequence, timed to arrive as site crews finished each camp zone. Staging at the port kept trucks moving without congestion at the gate. The atacama camp received units in the order crews could lift and connect them. Wanbang's rapid deployment response capability supported schedule changes during transit. A rapid deployment response plan covered re-sequencing when a vessel slipped. Custom quick-assembly flat-pack units and standard quick-assembly flat-pack units shared the same lifting points, so crews handled mixed loads without retraining. This discipline carried the delivery through remote Chile terrain, and every delivery milestone held against the master schedule. Installation and On-Site Execution Site Preparation and Lifting Site preparation began with the ground itself. Crews leveled and stabilized each pad before any unit arrived, because shifting sand and uneven terrain can stall ground work at remote sites. Utility planning ran in parallel. Medium-voltage grid service stepped down through on-site transformer and switchgear to the module input, and backup generators with automatic transfer switches covered the gap. Drainage prevented water from pooling under the modules, and windbreak structures protected exposed approaches. Dust control treated door seals, window systems, and ventilation intakes as one coordinated barrier. Lifting followed a model-specific plan with approved lifting points and trained operators. The team matched crane capacity to unit size, and the table below shows the working figures for expandable houses. House Size Crane Capacity Needed 20ft 25 tons 30ft 35 tons 40ft 50 tons Actual capacity depended on lifting distance, site access, crane radius, and local conditions. Mobile cranes, forklifts, lifting straps, hydraulic tools, and level measurement tools rounded out the kit. During roof lifting, the crane stayed engaged until temporary support rods were installed. Wanbang supplied installation drawings, fasteners, sealant, and guidance as part of its end-to-end service. Flat pack, folding, and expandable units each followed their own assembly sequence, and the rapid deployment response plan kept crews aligned when arrivals shifted. Quality Checks and Commissioning Commissioning started before the first switch was thrown. The water treatment modules passed a structured checklist covering feed analysis, membrane protection, pretreatment, chemical dosing, instrumentation, sampling points, and mechanical readiness. Permeate pressure could not exceed feed pressure by more than 5 psi (0.3 bar), and interlocks prevented operation when dosing pumps were off. Potable water and power generation modules received comparable checks, and instrument calibration was verified against plan. Handover to operational readiness followed a fixed sequence. Crews confirmed utility connections, tested alarms and time-delay relays, and ran each auxiliary stream through its operating range. The atacama camp reached full readiness on schedule. This discipline echoed the prefabrication strategy that shaped the whole delivery, and it showed how mining camp modular buildings can move from arrival to service without extended site work. The rapid deployment response capability gave the team room to absorb late changes, and the atacama desert conditions never disrupted the commissioning window. For future mining projects, the lesson is simple: plan the lift, verify the systems, and hand over with evidence. Results: 150 Modular Units Delivered Schedule, Cost, and Safety Outcomes All 150 modular units delivered on schedule. The auxiliary services—water treatment, potable water, and power generation—passed commissioning and reached operational readiness. The camp of 150 units supported an award-winning workforce accommodation project tied to the power transmission scheme. This outcome confirms the 150 modular units delivered for the Chile project met every milestone. Modular construction compresses programme durations because site works and building production run simultaneously. That overlap reduced delivery risk across the Atacama site. Staged scale-up lowered initial capital exposure while keeping an upgrade pathway open. Safety performance held because lifting plans, temporary supports, and access arrangements were coordinated before units arrived. Lessons for Future Mining Projects Early modular planning reduces risk in mining infrastructure. Transport logistics assessed during design confirm module dimensions fit road envelopes and weights comply with bridge limits. Early cost assessment in the study phase confirms whether the 10%–30% savings apply before committing to modular delivery. Early Planning Activity How It Reduces Project Risk Transport logistics assessed early in design Confirms module dimensions fit road envelopes and weights comply with bridge limits Construction engineering and temporary works planning Coordinates lift planning, temporary supports, and access for safe installation Early cost assessment in the study phase Confirms whether the 10%–30% savings apply before commitment Designing the module-to-site interface Addresses foundations and earthworks early for seamless installation Reduced temporary infrastructure requirements Shrinks camp sizes and lowers logistical burden Addressing transport, engineering, and integration factors early allows modules to be integrated seamlessly, reducing installation risk and supporting efficient, predictable project delivery. Logistics sequencing matters equally. Heavy haul expertise, multi-modal transport, and just-in-time delivery keep site congestion low. A design lock roughly six months before full production prevents late changes. This modular camp project case study shows that standardized mining camp modular buildings and disciplined sequencing turn remote complexity into repeatable results.   Integrated planning, purpose-built design, coordinated logistics, and disciplined installation carried the 150 modular units delivered for this Chile project. The 150 integrated housing units brought water treatment, potable water, and power generation to operational readiness on schedule. Staged delivery kept on-site disruption low across the Atacama Desert. The Chile case study offers clear guidance for future mining work. Early modular planning, sequenced logistics, and standardized designs turn remote complexity into repeatable results. Teams that apply these lessons can expect faster auxiliary-service readiness and calmer site execution on their next Atacama camp. For projects requiring a larger integrated building solution, Wanbang also offers steel structure buildings for industrial and infrastructure applications. FAQ What did the Chile project deliver?
