80x80 Fleet Maintenance Garage

Quantities, not prices, are publishable here: roof cladding runs 6,597 square feet — 3% above the 6,400-square-foot floor at a 3:12 pitch — with 79 cubic yards of nominal slab beneath it. Interior divisions are the last decision that should be fixed, because they are the first one that usually changes.

The check position costs floor area that carries no vehicle overnight, and it is the first thing cut on paper. It is also the item with the clearest operational return, so it deserves to be argued for explicitly rather than assumed.

• 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

This page is ordered around the floor itself, because at 80x80 the 6,400 sq ft available decides what a fleet garage can hold before any other consideration applies.

The footprint holds 12 vehicle stands — 6 across by 2 deep — and leaves 14 feet of depth for a check position where a vehicle can be looked over, topped up and released without occupying the route the rest of the fleet is using.

Read this footprint through its span. 80 feet across is the fixed constraint; 80 feet of length is the negotiable one, and at 1 to 1 the building is close to square, so movement runs in both directions. Ground conditions and drainage decide the floor before the frame 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. It is reached several movements per vehicle per day, concentrated into a morning release and an evening return. A 80 by 80 footprint is a near-square plan: 6,400 sq ft enclosed by 320 ft of wall, at a 1:1 length-to-width proportion. Along its 80 ft dimension it takes 3 runs of vehicle stands at 24 ft, leaving 8 ft over — the 8 ft is where the argument about this size actually happens. Taken purely as arithmetic, 80 by 80 gives 5 vehicle stands across the 80 ft dimension once 18 ft is reserved for movement, and 3 deep along the 80 ft dimension. Run as a a dispatch floor with a daily-check position held back from the parked rows, 2 ft across is below the 12 ft this use needs to be worth planning, so the leftover cannot hold a check position, so daily checks happen on the route and every check stops the release The vehicle that is hardest to place is usually the newest one, bought after the building was drawn.

At 80x80 the operating question is a specific one: where does a vehicle stand while it is being checked, without that check blocking the fleet behind it? 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 dispatch floor with a daily-check position held back from the parked rows rather than as generic covered area.

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 compact parking base that shelters a handful of vehicles and nothing else: there is no end strip, so equipment travels in the vehicles and the first stand becomes the store. Allocation is three-part: the parked rows, the route that serves them and a held-back position with space to open doors and a bonnet at once. The held-back position is the part most plans omit and the part that decides whether a defect delays one vehicle or the whole roster.

Because 14 feet clears the 12 feet this platform treats as usable, the end of the run is a room rather than a gap: 1,120 square feet for a check position where a vehicle can be looked over, topped up and released without occupying the route the rest of the fleet is using. Neighbouring buildings, setbacks and the approach road often decide the orientation before the plan does.

Spare width is the more valuable of the two leftovers here: a continuous 8-foot strip beats the same area stranded at the end of the run, because it touches every position along the way. The plan should survive the day the largest item the operation owns has to come inside.

The longest internal travel on a 80 by 80 plan is about 113 ft corner to corner, and the shortest useful one is the 80 ft cross-run. For a a dispatch floor with a daily-check position held back from the parked rows that matters where daily check position planning sits, because shortening the 80 ft run to serve it lengthens every trip along the 80 ft dimension. The yard outside decides how well the building works, because every movement starts and ends there. The perimeter is fully enclosed and secured, because keys, fuel cards, tooling and telematics live with the vehicles. That movement pattern, not the 6,400-square-foot total, is what decides whether the leftover 14 feet is useful here.

Nominal bay division computes to 4 bays at about 20 feet, wider than the 12-foot module — so a position can sit inside a bay without a frame line splitting it. A leftover strip earns its place only when something is deliberately put in it; otherwise it is circulation with a nicer name.

Depth here creates a hierarchy: 2 rows means front positions get used and rear positions get filled. Deciding which is which up front is what keeps 80x80 workable. The corner nobody plans for is the one that fills first, which is an argument for planning it.

Expansion here adds stands, but the check position has to grow with them or the ratio worsens. A base that doubles its vehicles without doubling its held-back capacity gets slower, not just fuller.

Configured as a dispatch floor with a daily-check position held back from the parked rows, 80x80 is judged on whether the 12 vehicle stands it holds match the operation, and on whether the 8 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 80-foot length being bought for depth, or for the repeated bays — six to eight repeated bays, and the bay line becomes the organising device for the whole plan?
• 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?

One opening per position works on this gable: 6 across 80 feet, with 8 feet of wall to distribute as piers. Splitting that margin evenly is what keeps the elevation buildable. Plan the exit as carefully as the entrance; buildings are emptied under more time pressure than they are filled.

Two drive openings start to pay for themselves at this scale, because they let the released vehicles and the held-back one use different paths. Where they sit relative to the yard gate matters as much as their width.

The stored configuration carries a 14-foot eave and computes to 24 feet at the ridge on a 3:12 pitch — a 10-foot rise across 80 feet. Height is therefore not uniform, and the sidewall is the constraint. What the building holds in its busiest week is the honest brief; the rest of the year is slack.

Height on a 80 ft span is a separate decision from the 80 ft length, and it is the span that sets the frame's behavior. Raising the eave over 6,400 sq ft affects every bay along the 80 ft dimension, so the test is whether daily check position planning genuinely needs the extra clear height or only the floor area.

• 40x70 moves the count from 12 to 6 vehicle stands (3 across by 2 deep), which is the reason to choose between them.
• 30x100 moves the count from 12 to 6 vehicle stands (2 across by 3 deep), which is the reason to choose between them.
• 50x60 moves the count from 12 to 3 vehicle stands (3 across by 1 deep), which is the reason to choose between them.

Because this footprint is planned as a dispatch floor with a daily-check position held back from the parked rows, the useful next reads are different from the ones a differently shaped fleet garage suggests: daily check position planning, fleet defect handling, two-door circulation.
