100x150 Fleet Maintenance Garage

This page is ordered around access, because on a 100-foot endwall the opening arrangement settles how a fleet garage at 100x150 is actually used.

The footprint holds 28 vehicle stands — 7 across by 4 deep — and the remaining 14 feet is marginal: the remainder cannot carry a driver strip, so people and vehicles share the same floor at the busiest minute of the day.

Efficiency is the useful number here: 536 square feet of enclosed floor per vehicle stand, against a 364-square-foot module. That leaves working slack around each position. Doors and their approaches decide more about daily use here than the enclosed area does.

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 150 footprint is a clearly directional plan: 15,000 sq ft enclosed by 500 ft of wall, at a 1.5:1 length-to-width proportion. Along its 150 ft dimension it takes 5 runs of vehicle stands at 28 ft, leaving 10 ft over — the 10 ft is where the argument about this size actually happens. At hub scale the building stops being a garage and becomes a piece of scheduling infrastructure. Two shifts overlap, drivers arrive on foot while vehicles are moving, and the plan's real subject is separation: which door people use, which door vehicles use, and where the two are never in the same place. Keys, telematics and paperwork have to live somewhere that is not the driver's seat.

At 100x150 the operating question is a specific one: when two shifts overlap, do the arriving and departing vehicles use the same ground? That is a different question from the one a fleet garage of another shape has to answer, and it is why this footprint is planned as a shift hub where release, return and support all run at once rather than as generic covered area.

The 100-foot gable can carry 7 openings, one per vehicle stand, with 9 feet of wall left for piers between and beside them — the arrangement that keeps each position independently reachable. Neighbouring buildings, setbacks and the approach road often decide the orientation before the plan does.

Separate entry and exit openings, and a personnel door that is nowhere near either, are the arrangement this scale asks for. Marked walking routes matter here for reasons the frame cannot solve.

At 25-foot nominal bays the structure works with the layout instead of against it: one vehicle stand per bay line, walls free of awkward half-positions. Two operations of the same size can want opposite plans, so the arithmetic below is a starting point rather than a recommendation.

With 4 rows deep, the rear row is behind the front one. Without a route past it, those vehicle stands become storage positions rather than working ones — the real cost of depth at this width. An empty building looks generous and a working one rarely does; plan against the working state.

Hubs grow by adding a defined zone, not by squeezing rows tighter. When a hub is full, the honest answer is usually a second site or a second shift rather than a denser floor.

Configured as a shift hub where release, return and support all run at once, 100x150 is judged on whether the 28 vehicle stands it holds match the operation, and on whether the 9 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 150-foot length being bought for depth, or for the repeated bays — a long repeating bay sequence, so segment boundaries are set by bay lines rather than by walls?
• 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?

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 base that keeps a working service bay alongside the parked fleet: the remainder is too narrow for a true service bay, so work happens in a parking stand and the tools travel to the vehicle. Dividing the 15,000 sq ft by the 13 by 28 ft vehicle stand gives roughly 25 positions before circulation is deducted a second time for cross movement. Whether the plan keeps 25 or drops to 20 comes back to the question this footprint is really answering: when two shifts overlap, do the arriving and departing vehicles use the same ground?

There is no end zone at this footprint. 14 feet is circulation slack, not floor area with a purpose, and the remainder cannot carry a driver strip, so people and vehicles share the same floor at the busiest minute of the day. The building is fixed for decades while the operation inside it changes every few years, and the plan has to survive that.

The 9 feet of spare width runs the whole 150-foot length — 1,350 square feet of wall strip. It earns its keep as shelving, staging or a walking route, not as another vehicle stand. The floor treatment is a use decision that outlasts most of the equipment standing on it.

The longest internal travel on a 100 by 150 plan is about 180 ft corner to corner, and the shortest useful one is the 100 ft cross-run. For a a shift hub where release, return and support all run at once that matters where shift overlap planning sits, because shortening the 100 ft run to serve it lengthens every trip along the 150 ft dimension. The vehicle that is hardest to place is usually the newest one, bought after the building was drawn. What it holds is licensed vehicles that earn their keep on the road, not machinery parked between seasons. That movement pattern, not the 15,000-square-foot total, is what decides whether the leftover 14 feet is useful here.

Across a 100-foot span the 4:12 pitch adds 16.7 feet between eave and ridge. The centreline measures 40.7 feet; anything parked or stacked near a wall lives with the 24-foot eave. Ground conditions and drainage decide the floor before the frame does.

Consistent height across a large floor is worth protecting: the tallest vehicle in the fleet sets the requirement everywhere, because a hub cannot rely on any one vehicle keeping to any one bay.

No price appears on this page. The quantities that scale an estimate at 100x150 are 15,000 square feet of slab, 277.8 cubic yards of nominal concrete, 12,000 square feet of wall cladding and 15,811 square feet of roof cladding. The plan should survive the day the largest item the operation owns has to come inside.

Proportion drives cost here as much as size does: 500 ft of wall around 15,000 sq ft is 0.033 ft of wall per enclosed square foot, and a squarer plan of the same area would carry less. What moves the figure further on a a shift hub where release, return and support all run at once is the fit-out shift overlap planning implies, along with framed openings and the height chosen for the 100 ft span.

• the number of lanes and openings the dispatch window needs
• charging or fuelling infrastructure positions
• opening height set by the tallest fleet vehicle
• yard staging area outside the building

• 60x100 moves the count from 28 to 15 vehicle stands (5 across by 3 deep), which is the reason to choose between them.
• 50x120 moves the count from 28 to 12 vehicle stands (3 across by 4 deep), which is the reason to choose between them.
• 80x80 moves the count from 28 to 12 vehicle stands (6 across by 2 deep), which is the reason to choose between them.

Because this footprint is planned as a shift hub where release, return and support all run at once, the useful next reads are different from the ones a differently shaped fleet garage suggests: shift overlap planning, pedestrian and vehicle separation, large fleet circulation.
