Shelves Against the Dust

The corrugated iron cladding had taken three days. Alastair Drummond and his crew fixed the galvanised sheeting to the steel frame in horizontal runs, working from the bottom up, each sheet overlapping the one below it by a single corrugation to shed water. It was straightforward work — drill, bolt, move, repeat — but the sheer surface area of a fifteen-by-thirty-metre building meant that even a competent crew of six covered ground more slowly than anyone's impatience preferred. Ewan Maitland handled the roof sheets, working methodically along the trusses with the surefootedness of a man who had spent decades at height on New Edinburgh's timber-framed buildings. Callum Baird passed sheets up to him from below, learning through repetition the particular rhythm of construction work — lift, position, hold, wait for the drill, release, step sideways, lift again.

The roll-up steel doors had arrived through the portal pre-assembled — two wide vehicle-access doors for the building's eastern face and a smaller staff entry door on the northern side. Tavish Renfrew fitted them on the fourteenth of September, welding the guide rails to the steel frame and testing the rolling mechanism with the particular thoroughness of a man who understood that a door which jammed in an emergency was worse than no door at all. The vehicle doors rolled smoothly on their tracks. The staff door swung on heavy-gauge hinges that Tavish had reinforced with additional weld passes at the pivot points — a precaution born from New Edinburgh experience, where doors that saw daily use in harsh conditions failed at their hinges before they failed anywhere else.

The interior fit-out belonged to the HVAC and electrical technicians — two men who had been delivered through the portal specifically for this stage of construction, arriving in Bixbus with toolkits and a manifest of equipment that included solar panels, inverters, LED lighting strips, ventilation fans, refrigeration compressors, and the insulated wall panels for the walk-in freezer and cooler. Their work occupied the final three days of the build, and it transformed the Supply Depot from an empty steel shell into something that functioned.

The solar panels went onto the roof first — eight panels arranged in two rows of four across the northern pitch, oriented to catch the maximum available light. The wiring ran through conduit along the roof trusses and down the interior face of the western wall to an inverter and battery bank positioned near the staff entrance. The system was modest by Earth standards but sufficient to power the building's lighting, ventilation, and — critically — the cold storage units that would preserve perishable animal feed and veterinary supplies.

The walk-in freezer and cooler were assembled in the building's northwest corner. Each unit occupied a three-by-three-metre footprint, their insulated panels bolting together into sealed chambers with heavy-duty doors and magnetic gaskets. The compressors, mounted externally against the building's northern wall, connected to the solar power system through a dedicated circuit that the technicians tested repeatedly before declaring it operational. The freezer held its target temperature within two hours of being switched on. The cooler stabilised within one. In a settlement that had been storing perishable goods in whatever shade could be found and consuming them before they spoiled, the existence of reliable refrigeration represented a quiet revolution in operational capability.

Steel shelving went up along the eastern and southern walls — floor-to-ceiling racking in standard modular sections that bolted together without welding. Ewan Maitland assembled the shelving with the systematic efficiency of a man who found satisfaction in ordered spaces, levelling each shelf with a care that Alastair observed was perhaps excessive for a storage facility but chose not to discourage. The shelving divided the building's interior into logical zones: tools and hand equipment along the eastern wall, construction materials and fencing supplies along the southern wall, animal feed and consumables nearest the cold storage, and veterinary supplies in a locked cabinet near the staff entrance.

LED strip lighting, mounted along the underside of the roof trusses, illuminated the interior with a clean, even light that made the building's steel-and-concrete surfaces look almost clinical. Ventilation fans set into the upper walls provided air circulation that would prevent moisture buildup and keep the working environment tolerable during the warmer months. Fire extinguishers were mounted at four points. Safety signage was fixed beside each door. A first-aid kit was bolted to the wall near the staff entrance — a detail that Alastair had insisted on, citing a New Edinburgh construction tradition that no building was considered complete until it contained the means to treat an injury sustained within it.

Adrian Pafistis arrived on the morning of 17 September for the final walkthrough. He had visited the site intermittently during the cladding and fit-out stages, checking progress and signing off on each completed system, but this was the formal inspection — a systematic review of the entire building against the construction specification he had drawn up with Grant three weeks earlier.

He began at the foundation, inspecting the slab edges where the formwork had been stripped away to reveal clean concrete margins. He checked the drainage channels. He tested the door mechanisms. He walked the interior methodically, running a hand along welded joints, pressing his weight against shelving to test its anchorage, opening and closing the cold storage doors, verifying that the magnetic gaskets sealed properly. He checked the solar panel connections on the roof. He tested every light. He read the amperage on the inverter display and compared it to the technicians' commissioning report.

Grant Ironbach arrived while Adrian was still on the roof. He waited at the staff entrance with his project plan — the same rolled document he had carried to the groundbreaking, its margins now annotated with dates, tick marks, and the occasional correction in his small, precise handwriting. When Adrian descended and confirmed that the building met specification, Grant entered the Supply Depot and conducted his own inspection.

Grant's walkthrough was different from Adrian's. Where Adrian had checked systems and structure, Grant checked purpose. He stood in the centre of the building and looked at the empty shelving and saw what would fill it — the fencing wire for the Meadow Enclosure, the timber posts for the Canopy Enclosure, the bags of seed for habitat planting, the veterinary supplies that Dr. Hargrove would organise when she arrived, the animal feed that would sustain species not yet present in Bixbus. The building was complete. What it represented was just beginning.

The afternoon was spent moving in supplies. Everything that had been stored under tarpaulins at the sanctuary site since the groundbreaking — tools, bags of cement, rolls of wire mesh, fencing posts, boxes of bolts and fixings — was carried into the Supply Depot and placed on the shelving that Ewan had assembled. Jerome Smith and Callum Baird handled the heaviest loads, hauling sacks of animal feed pellets that had been delivered through the portal earlier that week and stacking them in the zone nearest the cold storage. Hamish Kincaid carried tools with the deliberate care of a man who believed that how you stored your equipment reflected how you used it. Kain Jeffries, back from another rotation on perimeter duties, moved construction materials onto the southern shelving with the efficient indifference of someone who had spent enough time in Bixbus to stop being impressed by new buildings and start expecting them.

The frozen supplies went in last. Sealed containers of animal feed concentrates, veterinary medications requiring cold storage, and biological samples that the supply network had begun delivering in anticipation of the sanctuary's eventual operation were transferred into the walk-in freezer and cooler. The compressor's hum, barely audible from outside the building, became the Supply Depot's permanent background sound — a low, mechanical pulse that would run continuously from this day forward, powered by sunlight collected on a steel roof in a settlement that had not existed two months ago.

Sarah Ironbach visited the completed building in the late afternoon. She walked the interior with Grant, examining the shelving layout and the cold storage facilities with the practiced eye of someone who had managed supply logistics at Bonorong and knew exactly how a facility like this would be used once it was operational at scale. She moved three items on the shelving to different positions — adjustments that Grant noted without comment and did not reverse — and spent several minutes in the cooler assessing its capacity against the feed storage requirements she had been calculating for the first phase of animal arrivals.

By evening, the Sanctuary Supply Depot was operational. Its shelves held supplies. Its cold storage maintained temperature. Its doors locked. Its solar panels would charge the battery bank overnight to power the following day's operations. The building smelled of new steel, fresh concrete, and the faint chemical sharpness of refrigerant — smells that would gradually be overlaid by animal feed, timber, soil, and the accumulated residue of daily use, but that on this first evening retained the particular clarity of something unused.

Outside, the Operations Hub frame was visible twelve metres to the north, its corrugated iron cladding half-complete. Alastair's interleaved schedule had kept the crew productive throughout the Supply Depot's construction — the Ops Hub foundation had been poured during the Supply Depot's curing period, its frame erected while the Supply Depot was being clad, its own cladding now progressing while the Supply Depot's interior had been fitted out. The two buildings were rising in parallel, each one's idle periods filled by the other's active stages, exactly as Alastair and Adrian had planned.

The peafowl had discovered the Supply Depot two days earlier. The peacock had investigated the building's interior during the fit-out stage, walking through the open vehicle doors with the imperious curiosity of a creature that considered all structures within its territory subject to personal inspection. Callum had attempted to discourage it. The peacock had regarded him with one flat, golden eye and continued its survey. It had not returned since the doors were fitted and closed, but on the evening of the building's completion it was visible on the track between the Supply Depot and the Operations Hub, picking through the construction debris with the air of a proprietor reviewing his holdings.

Grant locked the staff entrance as the light faded — the first time a door had been locked at the Bixbus Wildlife Sanctuary. He pocketed the key, noted the completion date in the margin of his project plan, and walked back toward the main settlement. Behind him, the Supply Depot's solar panels caught the last of the light, and the freezer compressor hummed steadily in the new dark.
