80x150 Fleet Maintenance Garage

This page is ordered around the working arrangement, because the 150-foot depth at 80x150 is what gives a fleet garage its usable sequence of zones.

The footprint holds 15 vehicle stands — 5 across by 3 deep — and leaves 28 feet of depth for an oversize position for the one vehicle that does not fit the standard stand, kept where its maneuver does not sweep the rows.

Efficiency is the useful number here: 800 square feet of enclosed floor per vehicle stand, against a 448-square-foot module. That is generous — the footprint is doing more than hold modules. The floor treatment is a use decision that outlasts most of the equipment standing on it.

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. It is reached several movements per vehicle per day, concentrated into a morning release and an evening return. A 80 by 150 footprint is a clearly directional plan: 12,000 sq ft enclosed by 460 ft of wall, at a 1.9:1 length-to-width proportion. Along its 150 ft dimension it takes 4 runs of vehicle stands at 32 ft, leaving 22 ft over — the 22 ft is where the argument about this size actually happens. Taken purely as arithmetic, 80 by 150 gives 3 vehicle stands across the 80 ft dimension once 26 ft is reserved for movement, and 4 deep along the 150 ft dimension. Run as a a covered yard for a mixed fleet of very different vehicle sizes, 12 ft across is below the 18 ft this use needs to be worth planning, so there is no oversize position, so the largest vehicle parks where it fits and the layout reorganizes itself around it Keys, telematics and paperwork have to live somewhere that is not the driver's seat.

At 80x150 the operating question is a specific one: does the largest vehicle in the fleet dictate the whole grid, or does it get a position of its own? 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 covered yard for a mixed fleet of very different vehicle sizes rather than as generic covered area.

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. Ground conditions and drainage decide the floor before the frame does.

Depth here creates a hierarchy: 3 rows means front positions get used and rear positions get filled. Deciding which is which up front is what keeps 80x150 workable. Neighbouring buildings, setbacks and the approach road often decide the orientation before the plan does.

Growth in a mixed fleet is rarely uniform, so leave the flank next to the oversize position as the extendable one. That is where the next unusual vehicle will need to go.

Configured as a covered yard for a mixed fleet of very different vehicle sizes, 80x150 is judged on whether the 15 vehicle stands it holds match the operation, and on whether the 10 feet of spare width leaves the route this mode depends on.

• Does the work need racking or work zones on both sides with a full vehicle lane down the middle, or does it need a second lane that this 80-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?

What it holds is licensed vehicles that earn their keep on the road, not machinery parked between seasons. 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 12,000 sq ft by the 14 by 32 ft vehicle stand gives roughly 12 positions before circulation is deducted a second time for cross movement. Whether the plan keeps 12 or drops to 8 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?

Because 28 feet clears the 18 feet this platform treats as usable, the end of the run is a room rather than a gap: 2,240 square feet for an oversize position for the one vehicle that does not fit the standard stand, kept where its maneuver does not sweep the rows. Two operations of the same size can want opposite plans, so the arithmetic below is a starting point rather than a recommendation.

The 10 feet of spare width runs the whole 150-foot length — 1,500 square feet of wall strip. It earns its keep as shelving, staging or a walking route, not as another vehicle stand. An empty building looks generous and a working one rarely does; plan against the working state.

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. Turnaround time, not floor area, is the number a fleet base is judged on. The perimeter is fully enclosed and secured, because keys, fuel cards, tooling and telematics live with the vehicles. That movement pattern, not the 12,000-square-foot total, is what decides whether the leftover 28 feet is useful here.

Span drives headroom at 80x150: 80 feet of width on a 4:12 pitch puts 37.3 feet over the middle and 24 feet at the walls, so where a tall item stands matters as much as how tall it is. The plan should survive the day the largest item the operation owns has to come inside.

Height on a 80 ft span is a separate decision from the 150 ft length, and it is the span that sets the frame's behavior. Raising the eave over 12,000 sq ft affects every bay along the 150 ft dimension, so the test is whether mixed fleet stand sizing genuinely needs the extra clear height or only the floor area.

One opening per position works on this gable: 5 across 80 feet, with 10 feet of wall to distribute as piers. Splitting that margin evenly is what keeps the elevation buildable. A leftover strip earns its place only when something is deliberately put in it; otherwise it is circulation with a nicer name.

Opening size is set by the exception and position by the rule. One opening sized for the largest vehicle, placed where its swept path is clear, usually beats two average-sized openings placed conveniently.

Quantities, not prices, are publishable here: roof cladding runs 12,649 square feet — 5% above the 12,000-square-foot floor at a 4:12 pitch — with 222.2 cubic yards of nominal slab beneath it. The corner nobody plans for is the one that fills first, which is an argument for planning it.

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.

• 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

• 60x80 moves the count from 15 to 8 vehicle stands (4 across by 2 deep), which is the reason to choose between them.
• 40x120 moves the count from 15 to 12 vehicle stands (3 across by 4 deep), which is the reason to choose between them.
• 50x100 moves the count from 15 to 6 vehicle stands (3 across by 2 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.
