80x100 Fire and EMS Station Building

No price appears on this page. The quantities that scale an estimate at 80x100 are 8,000 square feet of slab, 148.1 cubic yards of nominal concrete, 7,200 square feet of wall cladding and 8,433 square feet of roof cladding. Interior divisions are the last decision that should be fixed, because they are the first one that usually changes.

Proportion drives cost here as much as size does: 360 ft of wall around 8,000 sq ft is 0.045 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 continuously staffed station with living quarters separated from the apparatus floor is the fit-out staffed fire station quarters implies, along with framed openings and the height chosen for the 80 ft span.

• apparatus door height and width
• drive-through bays versus reverse-in bays
• exhaust capture in the bays
• crew quarters as a separate conditioned envelope

This page is ordered around arrival, because in a client-facing office the first thirty seconds after the door decide how the rest of the plan has to work.

The footprint holds 12 quarters modules — 4 across by 3 deep — and the remaining 12 feet is marginal: there is no buffer between quarters and the bay, so noise, exhaust and traffic from the apparatus floor reach the living space directly.

Read this footprint through its span. 80 feet across is the fixed constraint; 100 feet of length is the negotiable one, and at 1.25 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 80 by 100 footprint is a mildly directional plan: 8,000 sq ft enclosed by 360 ft of wall, at a 1.3:1 length-to-width proportion. Along its 100 ft dimension it takes 4 runs of quarters modules at 24 ft, leaving 4 ft over — the 4 ft is where the argument about this size actually happens. A staffed station is occupied around the clock, so it has to work as living space and as a response building at the same time, and those two roles pull in opposite directions — quarters want quiet and separation, the apparatus floor wants a direct route to it. The plan's central decision is how much distance to put between them without lengthening the response path. A substation earns its size by doing deliberately less than a primary station, not by quietly duplicating the primary station's full program at a smaller footprint.

This footprint is planned as a continuously staffed station with living quarters separated from the apparatus floor. Spent as a square 89 by 89 instead, the same 8,000 sq ft would stand 4 quarters modules across rather than 3, and would trade this plan's length for parallel access. That is the width-against-depth decision this footprint has already made. Compared with a 80 by 80 of the same width, the extra depth here adds run rather than reach: it buys about 4 quarters modules in line, and every position past the second is retrieved by moving what stands in front of it. A building of this size behaves like a small yard under a roof: zones need to be defined, signed and left alone, or they migrate. The building runs on two schedules at once — daily living routines and an interruption sequence that has to work at any hour. Furniture, doors and floor finishes in the connecting zone are chosen for that interruption sequence rather than for the daily routine alone. Clearance in the apparatus bay follows the tallest apparatus expected to be housed there, not the ceiling height anywhere else in the building.

The 80-foot gable can carry 4 openings, one per quarters module, with 8 feet of wall left for piers between and beside them — the arrangement that keeps each position independently reachable. Plan the exit as carefully as the entrance; buildings are emptied under more time pressure than they are filled.

Beyond the apparatus doors, the door and route from quarters to the bay matter more than any other opening in the building; a direct, unobstructed path is the priority, and it should not pass through public or administrative space.

The staffing and turnout pattern this station could equally be planned for is a volunteer station members drive to and park apparatus in, entering and exiting through the same bay front: there is no turnout area between the bays and the day room, so gear is staged wherever there is a wall left over and members cross the bay floor to reach it. Dividing the 8,000 sq ft by the 18 by 24 ft quarters module 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 route from quarters to the apparatus stay short and direct, while the quarters themselves stay separated enough from the bay to function as a place to rest?

The 12-foot leftover depth falls under the 14 feet this platform treats as usable for a fire and ems station building, so there is no buffer between quarters and the bay, so noise, exhaust and traffic from the apparatus floor reach the living space directly. 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.

Spent as a square 89 by 89 instead, the same 8,000 sq ft would stand 4 quarters modules across rather than 3, and would trade this plan's length for parallel access. That is the width-against-depth decision this footprint has already made. Compared with a 80 by 80 of the same width, the extra depth here adds run rather than reach: it buys about 4 quarters modules in line, and every position past the second is retrieved by moving what stands in front of it. A building of this size behaves like a small yard under a roof: zones need to be defined, signed and left alone, or they migrate. The building runs on two schedules at once — daily living routines and an interruption sequence that has to work at any hour. Furniture, doors and floor finishes in the connecting zone are chosen for that interruption sequence rather than for the daily routine alone. Clearance in the apparatus bay follows the tallest apparatus expected to be housed there, not the ceiling height anywhere else in the building. That movement pattern, not the 8,000-square-foot total, is what decides whether the leftover 12 feet is useful here.

Nominal bay division computes to 4 bays at about 25 feet, wider than the 18-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: 3 rows means front positions get used and rear positions get filled. Deciding which is which up front is what keeps 80x100 workable. The corner nobody plans for is the one that fills first, which is an argument for planning it.

Quarters typically expand along their own wing rather than by extending toward the apparatus floor, keeping the buffer and the direct route intact as staffing needs grow.

Configured as a continuously staffed station with living quarters separated from the apparatus floor, 80x100 is judged on whether the 12 quarters modules 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 100-foot length being bought for depth, or for the repeated bays — eight to ten repeated bays, which makes the layout a scheduling problem as much as a spatial one?
• Is the tallest apparatus dimension measured with everything mounted?
• Drive-through or reverse-in, and what does the apron allow?

The stored configuration carries a 20-foot eave and computes to 33.3 feet at the ridge on a 4:12 pitch — a 13.3-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 100 ft length, and it is the span that sets the frame's behavior. Raising the eave over 8,000 sq ft affects every bay along the 100 ft dimension, so the test is whether staffed fire station quarters genuinely needs the extra clear height or only the floor area.

Ventilation across 8,000 square feet at this height: exhaust capture in the bays is planned as part of the building rather than added afterwards.

• 40x80 moves the count from 12 to 2 quarters modules (2 across by 1 deep), which is the reason to choose between them.
• 60x60 moves the count from 12 to 4 quarters modules (4 across by 1 deep), which is the reason to choose between them.
• 50x80 moves the count from 12 to 3 quarters modules (3 across by 1 deep), which is the reason to choose between them.

Because this footprint is planned as a continuously staffed station with living quarters separated from the apparatus floor, the useful next reads are different from the ones a differently shaped fire and ems station building suggests: staffed fire station quarters, apparatus bay to quarters route, 24-hour station layout.
