80x200 Industrial Steel Building

No price appears on this page. The quantities that scale an estimate at 80x200 are 16,000 square feet of slab, 197.5 cubic yards of nominal concrete, 7,840 square feet of wall cladding and 16,492 square feet of roof cladding. The span is the commitment; everything inside it is rearrangeable later, and the 80-foot dimension is not.

Proportion drives cost here as much as size does: 560 ft of wall around 16,000 sq ft is 0.035 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 floor planned around heavy static and moving loads is the fit-out heavy load floor planning implies, along with framed openings and the height chosen for the 80 ft span.

• clear height for plant and handling
• power capacity and distribution to plant positions
• slab requirements under fixed equipment, which are an engineering item
• opening positions at the flow ends

This page is ordered around where the heavy loads stand and how they travel, because those two decisions govern the slab, the route and the rest of the plan.

The footprint holds 8 load positions — 2 across by 4 deep — and the remaining 2 feet is marginal: there is no laydown margin, so items wait in the travel route and the floor is congested whenever two moves overlap.

Commitment first: 63% of the 16,000 square feet goes to load positions at 1260 square feet each, and 4,960 square feet survives as edge strip. A footprint is worth its own decision when that split lands where the work does. Rows that cannot be entered independently end up used as one long space.

A 80 by 200 footprint is a long corridor of a plan: 16,000 sq ft enclosed by 560 ft of wall, at a 2.5:1 length-to-width proportion. Along its 200 ft dimension it takes 4 runs of load positions at 45 ft, leaving 20 ft over — the 20 ft is where the argument about this size actually happens. Taken purely as arithmetic, 80 by 200 gives 2 load positions across the 80 ft dimension once 18 ft is reserved for movement, and 4 deep along the 200 ft dimension. Run as a a floor planned around heavy static and moving loads, 6 ft across is below the 12 ft this use needs to be worth planning, so there is no laydown margin, so items wait in the travel route and the floor is congested whenever two moves overlap Staff parking, deliveries and waste collection compete for the same corner of almost every industrial site.

This footprint is planned as a floor planned around heavy static and moving loads. Compared with a 80 by 150 of the same width, the extra depth here adds run rather than reach: it buys about 4 load positions in line, and every position past the second is retrieved by moving what stands in front of it. Spent as a square 126 by 126 instead, the same 16,000 sq ft would stand 3 load positions across rather than 2, and would trade this plan's length for parallel access. That is the width-against-depth decision this footprint has already made. At this scale the building is infrastructure rather than a shed; scheduling, traffic direction and separation of activities matter more than any single dimension. The longest internal travel on a 80 by 200 plan is about 215 ft corner to corner, and the shortest useful one is the 80 ft cross-run. For a a floor planned around heavy static and moving loads that matters where heavy load floor planning sits, because shortening the 80 ft run to serve it lengthens every trip along the 200 ft dimension. The apron outside the doors takes more punishment than the floor inside them and is more often under-specified.

The servicing pattern this shell could equally be operated under is a shell planned to divide between separate occupiers: there is no shared frontage strip, so tenancies share an approach and the yard has to be managed rather than divided. Load positions cluster along the strongest run of floor and the travel route between them is kept clear of everything else. Distributing heavy positions evenly across the floor turns the whole slab into a premium slab.

The 2-foot leftover depth falls under the 12 feet this platform treats as usable for a industrial building, so there is no laydown margin, so items wait in the travel route and the floor is congested whenever two moves overlap. Circulation width is the first thing surrendered under pressure and the first thing missed afterwards.

Spare width is the more valuable of the two leftovers here: a continuous 24-foot strip beats the same area stranded at the end of the run, because it touches every position along the way. Two feet of spare width reads as nothing on a plan and as a great deal when a machine is being turned.

Compared with a 80 by 150 of the same width, the extra depth here adds run rather than reach: it buys about 4 load positions in line, and every position past the second is retrieved by moving what stands in front of it. Spent as a square 126 by 126 instead, the same 16,000 sq ft would stand 3 load positions across rather than 2, and would trade this plan's length for parallel access. That is the width-against-depth decision this footprint has already made. At this scale the building is infrastructure rather than a shed; scheduling, traffic direction and separation of activities matter more than any single dimension. The longest internal travel on a 80 by 200 plan is about 215 ft corner to corner, and the shortest useful one is the 80 ft cross-run. For a a floor planned around heavy static and moving loads that matters where heavy load floor planning sits, because shortening the 80 ft run to serve it lengthens every trip along the 200 ft dimension. The apron outside the doors takes more punishment than the floor inside them and is more often under-specified. That movement pattern, not the 16,000-square-foot total, is what decides whether the leftover 2 feet is useful here.

Nominal bay division computes to 8 bays at about 25 feet, narrower than the 28-foot module — so frame lines land inside positions and the interior has to be set out from the columns. The plan is only as good as the route into it, which is a site question rather than a building one.

With 4 rows deep, the rear row is behind the front one. Without a route past it, those load positions become storage positions rather than working ones — the real cost of depth at this width. Whoever operates the building daily should read the plan before it is frozen, because they know where the pinch points are.

The heavy floor rarely extends; the light floor around it does. Planning the light end as the extendable one preserves the expensive part of the building.

Configured as a floor planned around heavy static and moving loads, 80x200 is judged on whether the 8 load positions it holds match the operation, and on whether the 24 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 200-foot length being bought for depth, or for the repeated bays — a long uninterrupted bay sequence that suits repetitive layouts and continuous processes?
• What direction does material flow, and are the openings at the right ends?
• Is overhead handling planned, and has that been raised as an engineering requirement?

One opening per position works on this gable: 2 across 80 feet, with 24 feet of wall to distribute as piers. Splitting that margin evenly is what keeps the elevation buildable. Security and after-hours access are easier to design in the door layout than to bolt on later.

The opening is specified from the largest load rather than the largest vehicle, and its approach outside needs the same clearance as the route inside. An opening that fits the item but not its handling equipment is the usual mistake.

Handling at fixed points matched to the flow, so a door in the wrong place turns into a permanent double handling cost.

Span drives headroom at 80x200: 80 feet of width on a 3:12 pitch puts 24 feet over the middle and 14 feet at the walls, so where a tall item stands matters as much as how tall it is. Daylight placement changes how a floor is used far more than its cost suggests.

Height on a 80 ft span is a separate decision from the 200 ft length, and it is the span that sets the frame's behavior. Raising the eave over 16,000 sq ft affects every bay along the 200 ft dimension, so the test is whether heavy load floor planning genuinely needs the extra clear height or only the floor area.

Ventilation across 16,000 square feet at this height: process air is a design requirement rather than general comfort ventilation.

• 80x80 moves the count from 8 to 3 load positions (3 across by 1 deep), which is the reason to choose between them.
• 60x120 moves the count from 8 to 4 load positions (2 across by 2 deep), which is the reason to choose between them.
• 50x150 moves the count from 8 to 4 load positions (2 across by 2 deep), which is the reason to choose between them.

Because this footprint is planned as a floor planned around heavy static and moving loads, the useful next reads are different from the ones a differently shaped industrial building suggests: heavy load floor planning, laydown margin, load travel route.
