How much steel is in a building?

9-18-16 update Mar 2018 Recent articles suggest that steel cost is expected to increase and this will almost certainly affect the cost of construction. But just how much of an affect would a cost increase have on total building cost? The cost increase that is being talked about is the mill price cost of steel, or something like pipe and tube producer price (PPI), since pipe and tube is a world trade item, but not a Fab Steel PPI. How Much Steel Required For House Construction The questions we need to answer are:

How much of a cost increase will we see in the raw product, manufactured raw steel? How much steel is used in a building? What affect will a raw material cost increase have on the cost of steel installed? How much does that change the cost of the building?

It might help to start with a basic understanding of steel manufacturing and use. Basic Oxygen Steel (BOS) steel making uses between 25 and 35% recycled steel to make new steel. BOS steel usually has less residual elements in it, such as copper, nickel and molybdenum and is therefore more malleable than EAF steel so it is often used to make automotive bodies, food cans, industrial drums or any product with a large degree of cold working.

  • Cold rolled steel is in this category which would include gypsum wall system steel studs and HSS Hollow Structural Sections.
  • Electric Arc Furnace (EAF) steel making contains more residual elements that cannot be removed through the application of oxygen and lime.
  • It is used to make structural beams, plates, reinforcing bar and other products that require little cold working.

EAF steel uses almost 100% recycled steel. Most steel that goes into a building or civil structure is in this category.2/3rds of all steel manufactured in the US is EAF steel. Typically quoted benchmark steel pricing that I’ve seen is based on either cold-rolled-coil sheet steel or hot-rolled-coil sheet steel.

  1. This is a common product used for the automotive industry or appliance, but not so much for the construction industry (steel studs vs structural steel).
  2. EAF Structural steel is nearly 100% dependent on recycled steel so is not as much affected by price changes of iron ore, as is BOS steel.
  3. The United States is the world’s largest steel importer.

Of the 30MMT imported, 50%+ of that comes from our top few import suppliers, Canada, Brazil, South Korea and Mexico. Russia supplies 7%-9%. No other country supplies more than 5% of our imports. China supplies less than 2% of our steel imports, The U.S.

  1. Is responsible for almost 10% of global steel imports, more than double the second largest importer. The U.S.
  2. Annually imports about $20-$25 billion of steel, $2 billion from Mexico.
  3. The United States consumes approximately 110 million tons of steel each year.
  4. More than 40 million tons is used in the construction industry.

The next largest industries, automotive and equipment and machinery, together do not use as much steel as construction. The U.S. imports about 30% of the steel it uses. How Much Steel Required For House Construction The graphic chart above is by American Iron and Steel Institute, Structural steel is the most widely used structural framing material for buildings used in the U.S. with nearly 50% market share in nonresidential and multistory residential buildings. Prior to the recession steel had a 60% market share. The table of data above is by Dodge Analytics, from this paper by American Institute of Steel Construction. Sources are also linked below. What affect might a steel cost increase have on a building project? It will affect the cost of structural shapes, steel joists, reinforcing steel, metal deck, stairs and rails, metal panels, metal ceilings, wall studs, door frames, canopies, steel duct, steel pipe and conduit,

Structural steel and reinforcing steel are hot-rolled long products, EAF steel. All the others are cold-rolled flat sheet BOS steel. Here are some averages of the percentage of steel material costs as related to total project construction cost. For a building that is predominantly masonry, these percentages would be reduced considerably.

For a heavy industrial building the percentages might be higher. Assuming a typical structural steel building with some metal panel exterior, steel pan stairs, metal deck floors, steel doors and frames and steel studs in walls, then all steel material installed represents about 14% to 16% of total building cost.

Structural Steel only, installed, is about 9% to 10% of total building cost, but applies to only 60% market share of steel buildings. The other 6% of total building cost applies to all buildings. Other steel is very likely higher to take into account any increased cost in major mechanical equipment such as chillers, pumps, fan powered boxes, cooling towers, tanks, generators, plumbing fixture supports, electrical panel boxes and cable trays.

If the structural steel subcontractor increases bid price by 10%, that raises the cost of the building by 1%, but if it is the mill price of steel that increases by 10% the increase to final building price is far less. It is the mill price of steel, rather than fabricated steel, that you would track in the producer price index (PPI).

The final cost of steel installed in a building is about four times the cost of the raw mill steel material used in making and installing the final product. Why so different? Well, for instance, structural steel cost includes: raw mill steel cost, delivery to shop, drafting, shop fabrication, shop paint, delivery to job site and shop markup.

At the job site it includes: unload and sort, field installation crew, welding machine, crane and operator, contractor’s overhead and profit and sales tax. Assuming a building as described above, a 10% increase in the cost of mill steel, which (material only) affects one fourth the cost of 16% of the total building cost, then a 10% increase in the cost of ALL mill steel may result in a composite price increase on a whole building of about 10% x ¼ x 16% = 0.4%.

A 10% increase in the cost of mill steel just for structure may result in a composite price increase on a whole building of about 10% x ¼ x 10% = 0.25%. So, if the mill cost of steel were to increase 10% from $700/ton to $770/ton prior to shop fabrication, for a $100 million building, that could add roughly 0.25% ($250,000) to the cost of the structural steel contract or roughly 0.4% ($400,000) to the total cost of all steel.

A 25% increase in mill steel could add 0.65% to final cost of building just for structure. It adds 1.0% for all steel in a building. For a project such as a steel bridge, where not just 16% of cost is steel material, but potentially 40% to 60% of cost is steel, a 25% increase in mill steel might add as much as 3% to 4% to final cost.

How It Works | ProMix Concrete If you’ve ever taken on a building project, you know that size matters. You don’t want to pay for more than you need, so when it comes to fresh concrete, the size of your project and the size of the equipment are important considerations. This is where our volumetric concrete mixer trucks come in handy. • Hand or Small Barrel Mixer on Site • Residential or Micro Commercial, Post Footings, Small Curbs etc. Typically used in residential or micro-commercial projects, these small concrete jobs, such as installing small curbs or post footings, are often addressed on-site, where the concrete batches are mixed by hand, with hand tools or small barrel mixers. • 6–10 Cubic Meter Capacity • One Batch Mixed at Plant • One Pour at a Time • Foundations, Walls, Floors and Other Structures for Commercial, Infrastructure and Large Residential Projects When serving the concrete needs of larger commercial, residential or infrastructure projects, such as building houses or apartments, usually ready-mix trucks are employed.

  • The typical trucks have a 6-10 cubic meter capacity and their concrete batches are produced off-site at a concrete plant.
  • These large batches are mixed at the plant and are delivered in big ready-mix drum trucks in one large pour and the trucks need to rotate their drums constantly to prevent over-curing, which can ruin the load.

This is why they are often known as “hot loads”, because they have to be used within a certain timeframe. • 6­–8 Cubic Meter Capacity • Minimum 1 Cubic Meter Pour • Several Smaller Pours or One Large Pour • Each Pour Mixed at Client Site to Meet Client Specifications and Timing • Small Foundations, Sidewalks, Landings, Stairs, Infrastructure, Backfill and Specialized Pours Our ProMix trucks have a 6- 8 cubic meter capacity, with the flexibility to deliver several smaller pours (minimum 1 cubic meter pour required), or one larger pour, each with the capability to custom-mix at your job site.

  • This makes our trucks uniquely versatile, allowing us to serve anything from smaller to larger loads, perfect for anything from commercial to residential projects, small foundations, sidewalks, stairs, infrastructure, backfill and other specialized pours.
  • And since our Volumetric Mixer Trucks produce concrete on-site, unlike ready-mix trucks, we can customize each batch to meet your project requirements.

Plus, it’s on-demand. We don’t start pouring until you require it.

    How do you calculate materials needed?

    The Basics of Material Estimating Even the most experienced and professional applicators can have trouble determining the appropriate amount of materials needed for their project. Underestimating or overestimating can have a tremendous impact on budget, product availability, project scheduling, forecasting and bidding.

    1. A successful project starts by taking an accurate lay of the land.
    2. Following are tips that will help pros confidently select which products to use, determine the quantities required for the project and avoid running short while on the job.
    3. Calculate Project Square Footage First, in order to determine how much material will be needed for a specific project, you must determine the square footage of the area you are surfacing.

    As a rule of thumb, measurements should always be rounded up and considered additional square footage to ensure the appropriate amount of material for the application. Surface conditions such as porosity, spalling, pitting, cracking and so forth will all result in the use of additional material.

    1. Adding square footage to measurements will help ensure materials do not run short during application.
    2. A lot of contractors like to use the “ten percent rule” for waste and order accordingly.
    3. Using a laser tape, measuring wheel or measuring tape is best to determine the length and width of the area that is being surfaced.

    If the work space is not a perfect square or rectangle, measuring from the furthest point of both the length and width will account for any shorter sides of the space. After measuring, round up to the next foot on the length and width measurements. Then, multiply the length and width to determine the total amount of square feet for that area.

    Length x Width = Total Area For example: 25′ x 40′ = 1,000 sq. ft. If the work area is the entire floorplan of a house or business, measuring the outside perimeter of the building will provide a good estimate for the space. While the assumption is that there will be too much material left over, it’s wise to remember that the perimeter is taking into account all of the nooks and crannies, such as closets, hallways and bedrooms.

    If overhead or vertical surfaces such as walls or stairs are being surfaced, be sure to take those areas into consideration, too. Determine Which Products to Use When applying system-based products, it’s important to use all of the appropriate materials to ensure job success.

    • Depending on the finish that the customer has selected, specifically whether it is a traditional broom finish, stamped texture, decorative flake or metallic epoxy, it is imperative to follow the system directions for that application.
    • Information about all of the systems, the products they include and their individual application instructions is available at and,

    Once a system is chosen, it’s important to list the products needed for application by referring to individual Product Data Sheets for directions for use, mixing and application instructions as well as the coverage rates. The coverage rates are needed to determine the quantity required to complete the project.

    Calculate Quantity of Materials Now that the area is known, as well as the products needed and coverage rates, it is time to calculate how much will actually be needed. It’s easy to figure out – simply take the total amount of square feet that were measured for the project, then divide the total amount of square feet by the coverage rate of the material.

    Square Feet of Area ÷ Coverage Rate = Quantity of Bags or Gallons For example: Let’s use the ¼” Stamp Overlay System to determine how many bags of S-1800 Super-Stamp Gray are required to stamp the total area. Super-Stamp is applied at ¼” and has a coverage rate of 25 square feet per bag.

    We will use the area we measured earlier for the example.1,000 sq. ft. ÷ 25 sq. ft./bag = 40 bags Now it’s time to figure out how many gallons of S-1710 Liquid Release Agent are needed to stamp the material. The Liquid Release has a coverage rate of 250-300 square feet per gallon. We want to make sure we have enough material and avoid running short while on the project, so let’s use 250 square feet as the coverage rate.

    One of the most common errors in figuring how much S-1710 Liquid Release Agent is required is forgetting that both the Super-Stamp overlayment and the stamps or skins must also be coated with the release agent.1,000 sq. ft. ÷ 250 sq. ft./gallon = 4 gallons for the Super-Stamp overlayment and 1,000 sq.

    • Ft. ÷ 250 sq.
    • Ft./gallon = 4 gallons for the stamps or skins, therefore you will need a total of 8 gallons of S-1710 Liquid Release Agent.
    • Once you identify the coverage rates for all the materials, you can use these formulas to calculate the appropriate amount of material you will need for your entire project.

    Calculating Cost of Materials Since you will essentially be getting more product than required for the project, the initial cost of your materials will be greater than the actual cost per square foot. This will fluctuate from project to project and result in accumulation of leftover materials that can be used on future projects.

    This will also help cover the cost of creating samples to aid in getting your next project approved. For example: 3.5 gallons of one product and 0.5 gallons of another may be needed, but because you are purchasing 4 gallons of the one, and 1 gallon of the other, the actual cost is more than what will be applied on the job.

    To properly bid on a project, a contractor needs to determine material cost. It’s important to remember that this doesn’t include any labor, freight charges, equipment rental or any outsourced or sub-contracted services. All factors should be considered before submitting the actual bid to a client.

    1. After determining the amount of material needed, just add up the actual cost of all the materials.
    2. To calculate the cost per square foot on material for the example project, divide the total cost of materials by the square footage.
    3. Let’s apply a cost of $3,060.16 to determine the cost per square foot.

    (Note: $3,060.16 is estimated and is not a true cost, it is only used for example) $3,060.16 ÷ 1,000 sq. ft. = $3.06/sq. ft. In the case that some services need to be subcontracted or equipment needs to be rented, those charges would be incorporated into the total landed cost.

    • Continuing with the example above, if grinding equipment had to be rented for two days at $65/day ($130 total), the new total cost would come to $3,190.16 and the cost per square foot would now be $3.19/sq. ft.
    • These same figures would be applied once the general overhead costs are determined, along with indirect expenses and, of course, your profit.

    Once again, divide that total by the total amount of square footage and it will generate the actual cost per square foot, allowing a contractor to accurately and confidently submit their bid.
