100x200 Fleet Maintenance Garage

This page is ordered around height and clearance, because at 100x200 the 26-foot eave limits a fleet garage sooner than the plan does.

The footprint holds 35 vehicle stands — 7 across by 5 deep — and the remaining 14 feet is marginal: there is no oversize position, so the largest vehicle parks where it fits and the layout reorganizes itself around it.

Read this footprint through its span. 100 feet across is the fixed constraint; 200 feet of length is the negotiable one, and at 2 to 1 the building is long for its width, so movement runs front to back. An empty building looks generous and a working one rarely does; plan against the working state.

A fleet garage is an operational vehicle facility: it is planned around getting a group of vehicles out on schedule and back again, not around storing them. Density is deliberately loose, because a vehicle blocked in is a vehicle out of service. A 100 by 200 footprint is a clearly directional plan: 20,000 sq ft enclosed by 600 ft of wall, at a 2:1 length-to-width proportion. Along its 200 ft dimension it takes 6 runs of vehicle stands at 32 ft, leaving 8 ft over — the 8 ft is where the argument about this size actually happens. A mixed fleet is the hardest case, because a grid sized for the largest vehicle wastes space on the smallest, and a grid sized for the average cannot accept the largest at all. This footprint is planned around the exception: one or two oversize positions, and a regular grid for everything else. Turnaround time, not floor area, is the number a fleet base is judged on.

This footprint is planned as a covered yard for a mixed fleet of very different vehicle sizes. Sequencing matters more than in a uniform fleet: the largest vehicle should be first out or last in, because any other position makes its maneuver everyone else's problem. Roster patterns change more often than buildings do, so a layout that depends on one roster ages badly. Turnover here is daily: most of what is inside at night is outside by mid-morning and back again before dark.

Span drives headroom at 100x200: 100 feet of width on a 4:12 pitch puts 42.7 feet over the middle and 26 feet at the walls, so where a tall item stands matters as much as how tall it is. The corner nobody plans for is the one that fills first, which is an argument for planning it.

Mixed fleets commonly include one item taller than the assumption — a tipper with the body raised, a rack, an aerial unit. Height should be checked against that item in its working condition, not its traveling one.

As for work on the assets themselves, routine checks, tire and fluid work and defect rectification happen in-house on dedicated bays. The operating pattern this base slips into when the roster changes is a small fleet base built around one concentrated morning release: there is no width for a sign-out corner, so the first stand doubles as the place drivers stop, which slows the release. Dividing the 20,000 sq ft by the 14 by 32 ft vehicle stand gives roughly 30 positions before circulation is deducted a second time for cross movement. Whether the plan keeps 30 or drops to 24 comes back to the question this footprint is really answering: does the largest vehicle in the fleet dictate the whole grid, or does it get a position of its own?

There is no end zone at this footprint. 14 feet is circulation slack, not floor area with a purpose, and there is no oversize position, so the largest vehicle parks where it fits and the layout reorganizes itself around it. Ground conditions and drainage decide the floor before the frame does.

Width is fully committed at 100x200. With 2 feet spare, wall storage and passing room compete with the vehicle stands directly. Neighbouring buildings, setbacks and the approach road often decide the orientation before the plan does.

Sequencing matters more than in a uniform fleet: the largest vehicle should be first out or last in, because any other position makes its maneuver everyone else's problem. Roster patterns change more often than buildings do, so a layout that depends on one roster ages badly. Turnover here is daily: most of what is inside at night is outside by mid-morning and back again before dark. That movement pattern, not the 20,000-square-foot total, is what decides whether the leftover 14 feet is useful here.

Openings are the pinch point here. With 2 feet of spare width the gable cannot host 7 separate doors, so access is either shared or moved to the 200-foot sidewall. What the building holds in its busiest week is the honest brief; the rest of the year is slack.

The 100 ft ends and the 200 ft sides offer very different opening budgets: 100 ft of end wall has room for one wide opening or two modest ones, while 200 ft of side wall can carry several without the openings competing. On this plan the deciding factor is whether mixed fleet stand sizing or swept path planning should be the first thing reached from the door.

Nominal bay division computes to 8 bays at about 25 feet, wider than the 14-foot module — so a position can sit inside a bay without a frame line splitting it. The plan should survive the day the largest item the operation owns has to come inside.

Two-plus rows change the access question entirely. Every rear position at 100x200 needs either its own opening or an aisle, and 2 feet of spare width is what that aisle has to come from. A leftover strip earns its place only when something is deliberately put in it; otherwise it is circulation with a nicer name.

Extension is cheapest along the 200 ft dimension, where each added bay repeats work already framed; widening past 100 ft is a different frame rather than a longer one. Growing to 100 by 232 adds a 7th run of vehicle stands — useful if the constraint is vehicle stands rather than the 8 ft already spare at the far end.

Configured as a covered yard for a mixed fleet of very different vehicle sizes, 100x200 is judged on whether the 35 vehicle stands it holds match the operation, and on whether the 2 feet of spare width leaves the route this mode depends on.

• Does the work need an interior street with independent zones on both sides and turning room at each end, or does it need a second lane that this 100-foot span cannot give?
• Is the 200-foot length being bought for depth, or for the repeated bays — a long uninterrupted bay sequence that suits repetitive layouts and continuous processes?
• How many vehicles have to leave within the same window, and does the lane order allow it?
• Are service positions separate from the parking lanes?

• 80x100 moves the count from 35 to 18 vehicle stands (6 across by 3 deep), which is the reason to choose between them.
• 60x150 moves the count from 35 to 20 vehicle stands (4 across by 5 deep), which is the reason to choose between them.
• 80x120 moves the count from 35 to 18 vehicle stands (6 across by 3 deep), which is the reason to choose between them.

Because this footprint is planned as a covered yard for a mixed fleet of very different vehicle sizes, the useful next reads are different from the ones a differently shaped fleet garage suggests: mixed fleet stand sizing, swept path planning, oversize vehicle provision.

No price appears on this page. The quantities that scale an estimate at 100x200 are 20,000 square feet of slab, 370.4 cubic yards of nominal concrete, 15,600 square feet of wall cladding and 21,082 square feet of roof cladding. Plan the exit as carefully as the entrance; buildings are emptied under more time pressure than they are filled.

The oversize provision is what the plan pays for, and it is worth naming as its own line so it survives value engineering. Removing it does not save its area; it moves the problem into the yard.
