80x120 Fire and EMS Station Building

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 16 quarters modules — 4 across by 4 deep — and the remaining 8 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.

Efficiency is the useful number here: 600 square feet of enclosed floor per quarters module, against a 432-square-foot module. That leaves working slack around each position. An empty building looks generous and a working one rarely does; plan against the working state.

A 80 by 120 footprint is a clearly directional plan: 9,600 sq ft enclosed by 400 ft of wall, at a 1.5:1 length-to-width proportion. Along its 120 ft dimension it takes 5 runs of quarters modules at 24 ft, leaving 0 ft over — the 0 ft is where the argument about this size actually happens. Taken purely as arithmetic, 80 by 120 gives 3 quarters modules across the 80 ft dimension once 16 ft is reserved for movement, and 5 deep along the 120 ft dimension. Run as a a continuously staffed station with living quarters separated from the apparatus floor, 10 ft across is below the 14 ft this use needs to be worth planning, so there is no buffer between quarters and the bay, so noise, exhaust and traffic from the apparatus floor reach the living space directly Whether a station needs quarters, how many bays are required, and how coverage is distributed across substations are determined by the department and the authority having jurisdiction, not by the building program.

This footprint is planned as a continuously staffed station with living quarters separated from the apparatus floor. Spent as a square 98 by 98 instead, the same 9,600 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 90 of the same width, the extra depth here adds run rather than reach: it buys about 5 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. Training or drill space works best kept physically separate from the apparatus floor, so a scheduled drill never has to be cleared before a response can proceed.

One opening per position works on this gable: 4 across 80 feet, with 8 feet of wall to distribute as piers. Splitting that margin evenly is what keeps the elevation buildable. What the building holds in its busiest week is the honest brief; the rest of the year is slack.

The 80 ft ends and the 120 ft sides offer very different opening budgets: 80 ft of end wall has room for one wide opening or two modest ones, while 120 ft of side wall can carry several without the openings competing. On this plan the deciding factor is whether staffed fire station quarters or apparatus bay to quarters route should be the first thing reached from the door.

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. Quarters, kitchen and common space form one zone; the apparatus floor and its support rooms form another; a defined buffer corridor connects them and carries the direct route without merging the two zones. Placing quarters directly against the bay wall trades comfort for a marginally shorter route that a well-planned buffer rarely costs.

There is no end zone at this footprint. 8 feet is circulation slack, not floor area with a purpose, and there is no buffer between quarters and the bay, so noise, exhaust and traffic from the apparatus floor reach the living space directly. Ground conditions and drainage decide the floor before the frame 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. Neighbouring buildings, setbacks and the approach road often decide the orientation before the plan does.

Spent as a square 98 by 98 instead, the same 9,600 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 90 of the same width, the extra depth here adds run rather than reach: it buys about 5 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. Training or drill space works best kept physically separate from the apparatus floor, so a scheduled drill never has to be cleared before a response can proceed. That movement pattern, not the 9,600-square-foot total, is what decides whether the leftover 8 feet is useful here.

Nominal bay division computes to 5 bays at about 24 feet, wider than the 18-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.

With 4 rows deep, the rear row is behind the front one. Without a route past it, those quarters modules become storage positions rather than working ones — the real cost of depth at this width. A leftover strip earns its place only when something is deliberately put in it; otherwise it is circulation with a nicer name.

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, 80x120 is judged on whether the 16 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 120-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?
• Is the tallest apparatus dimension measured with everything mounted?
• Drive-through or reverse-in, and what does the apron allow?

Span drives headroom at 80x120: 80 feet of width on a 4:12 pitch puts 35.3 feet over the middle and 22 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.

Quarters and administrative space can use residential or office-scale ceiling heights, while the apparatus bay needs its own clearance for the equipment housed there — treating the whole building as one uniform height wastes volume in the living areas or shortchanges the bay.

Ventilation across 9,600 square feet at this height: exhaust capture in the bays is planned as part of the building rather than added afterwards.

• 50x80 moves the count from 16 to 3 quarters modules (3 across by 1 deep), which is the reason to choose between them.
• 40x100 moves the count from 16 to 4 quarters modules (2 across by 2 deep), which is the reason to choose between them.
• 60x80 moves the count from 16 to 6 quarters modules (3 across by 2 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.

No price appears on this page. The quantities that scale an estimate at 80x120 are 9,600 square feet of slab, 177.8 cubic yards of nominal concrete, 8,800 square feet of wall cladding and 10,119 square feet of roof cladding. Plan the exit as carefully as the entrance; buildings are emptied under more time pressure than they are filled.

Proportion drives cost here as much as size does: 400 ft of wall around 9,600 sq ft is 0.042 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
