Construction Calculators

Draw an ordered outline on FloorCanvas, add up to five optional exclusion polygons, and calculate gross, excluded, and net area in one US/Metric app. Canvas edits remain local until Calculate is pressed; every reported area comes from the reviewed workbook.

Draw a floor plan on FloorCanvas with its rooms, windows and doors, set the wall height and each opening's height on the drawing or in the tables under it (and see them in 3D), and get the baseboard run and the baseboard and casing sticks to order, room by room, in US or Metric units. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Compare bids on the same scope of work. Each bid's price plus your allowance for every item it leaves out gives its normalized price; the bids are ranked by normalized price and then by duration, and the change orders after the award are added to the awarded bid to give the revised total, the revised duration and the margin against your estimate.

Estimate the concrete for slabs, strip footings, pads, piers, walls and solid stairs typed as element rows, or draw a slab on the page's drawing grid, exclude columns or drains and pour it through a 'Slab from the drawing' row, and get the concrete before and after waste, the bags and ready-mix loads with their costs, whether the pour is above a ready-mix threshold, and a rebar, mesh or entered reinforcement quantity, including a rebar takeoff across each slab's bounding rectangle. Typed dimensions and the concrete, bag, cost and reinforcement results are in US units; the drawing is in feet or metres and its areas in square feet or square metres. Over MCP the typed rows are the input; on the page, edits stay local until Calculate is pressed, and every figure comes from the reviewed workbook.

Estimate finish costs from a floor plan you draw: flooring, trim along the outline, wall finishes at your wall height, and doors and windows, each at your own unit price, with a regional factor and a contingency, and the total per square foot (or square metre) of floor.

Draw a deck on FloorCanvas, exclude a hot tub or a tree, mark its rails and stairs, set its height, and get the joists, beams, posts (a post at both ends of every beam, each cut to the deck height, with the post stock to buy) and footings with their concrete bags, the rim joists, the deck boards and screws (framing and boards follow the outline and its openings; shapes other than a plain rectangle are flagged for a site check), the railing posts and balusters for each rail run, and the risers, treads and stringers of each stair, in US or Metric units. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a slab or driveway on FloorCanvas, block out columns or drains, and get the concrete to order with waste, whether ready-mix is recommended, the trucks or bags it takes, and the length of control joints at your spacing, in US or Metric units. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a floor plan on FloorCanvas (rooms, interior walls, windows and doors), choose each room's floor (tile, plank, carpet, sheet vinyl or none) and its own product in the Materials panel, lay each room on the drawing (tiles and planks piece by piece, carpet and sheet vinyl in roll strips), and get the pieces laid and to buy, the boxes, the thinset and grout bags and the carpet and sheet vinyl to order, room by room and in total, in US or Metric units. A 3D view shows the walls and openings as drawn. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a floor plan on FloorCanvas (outline, interior walls, windows and doors), set the wall height and each opening's height, and get the studs, plate sticks, wall sheathing and nails to buy, with a header for every window and door, in US or Metric units. View the walls in 3D before you calculate. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a floor plan on FloorCanvas with its windows and doors, set the wall height, and get the exterior wall area net of openings, the attic area, the wall batts and attic bags to buy, and the R-value each surface reaches against your target, in US or Metric units. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

List a job's materials, labor, subcontractor and equipment costs line by line, set the overhead, profit and contingency rates and a sales tax on the materials or on the whole price, and get the direct cost, each markup, the tax and the total price to quote, with the markup and margin that price gives. As the requirement defines them, the markup and margin count the tax.

Draw a lot and the buildings and paved areas on it, say which are buildings, and get the lot coverage, the impervious share and the floor area ratio; coverage and the impervious share are checked against the limits you enter. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a floor plan on FloorCanvas (rooms, interior walls, windows and doors), set the wall height once and check each window's and door's height, lay the drywall sheets on the walls and ceilings with one button, and get the paint and primer to buy and the drywall sheets, compound, tape and screws, with each room's wall and ceiling areas, paint and sheets, in US or Metric units. A 3D view shows the walls and openings as drawn, and the laid sheets on the walls. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a patio on FloorCanvas, leave out columns, beds or planters, and get the pavers to order with pattern waste, the base gravel and bedding sand, the edge restraint along the outline and the polymeric sand bags, in US or Metric units. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a pool on FloorCanvas, leave out islands or planters, and enter the depth at each end and a fill rate to get the water volume in gallons or litres, the liner area, the coping length and the time to fill, in US or Metric units. The spreadsheet measures the perimeter from the drawn points; canvas edits stay local until Calculate is pressed, and every figure comes from the reviewed workbook.

Draw a roof on FloorCanvas, its ridges, hips and valleys and each facet's pitch, and get the true roof area, the squares, the shingle bundles and underlayment rolls, the starter strip, drip edge and ridge cap, the length of every roof line and a facet-by-facet schedule, in US or Metric units. Canvas edits stay local until Calculate is pressed; every figure comes from the reviewed workbook.

Draw a one-storey house's outline on FloorCanvas, add its windows and doors, set the wall height and each opening's height, mark which doors are exterior, enter your siding's piece length, width and exposure, and lay the siding on the walls. Get the pieces and squares to order, the J-channel, corner posts and starter strip, with each wall's length, area and pieces laid, and each room's openings, in US or Metric units. A 3D view shows the walls and openings, and the laid courses up to a drawing size limit. Canvas edits stay local until Calculate is pressed; the drawing counts the pieces it lays, and every other figure comes from the reviewed workbook. The piece count is in pieces of the size you enter, so enter your product's.

Draw a lawn on FloorCanvas, leave out beds and hardscape, and get the sod rolls and pallets, topsoil and grass seed to order, in US or Metric units. Canvas edits stay local until Calculate is pressed; every quantity comes from the reviewed workbook.

Enter a stair's total rise, your target riser height and tread depth, and get the number of risers and treads, the actual riser height, the total run, and the stringer length and count. The riser height, the tread depth, 2R + T and, when you enter it, the headroom are checked against limits you can change. If you enter the run you have and the stair would not fit, the riser count is reduced to fit and flagged. US or Metric units.
