Thermal insulation Estimating

How do you calculate thermal insulation? It is measured in m2. K/W. The R-Value is calculated as R = l/λ where l = the thickness of the material in metres and λ (lambda) is the thermal conductivity of the material in W/m.K. Most Common Thermal Insulation Materials Insulation Material Price / Sq. Ft. R-Value / Inch Fiberglass $ R-3.1 […]

Ductwork Takeoff

What is a duct takeoff? Duct takeoffs have big shoes to fill. They are the avenue by which air moves from the main duct pipe to a new branch. … Each new duct branch usually services another room in the home or building, and you want the air distribution to be the same for every room. […]

Piping Fabrication Cost Estimation

How do you calculate man hours for piping? For example, if the project mentioned above contains 4 stress critical lines (you have to calculate critical lines from P&ID) per stress system on an average, then the total number of stress critical lines are 250×4=1000. So total piping man-hours estimated would be approximately 1000 x 12=12000. How […]

Construction Cost Estimating Services – Estimators NYC – Construction Estimating Services

Construction material take-off lists are required for the preparation of detailed cost estimates of construction projects. The estimators use the material quantities, labor hours and unit rates, etc. to prepare a detailed cost estimate. So, an accurate take-off serves as a base for an accurate estimate. What is a construction cost estimate? Construction cost estimating is the process of forecasting the cost of building a physical structure. […]

How many sheets of plywood do I need calculator?

Divide by the total square footage by the square footage of a sheet of plywood to find the number of sheets required to cover the space. A 4×8 sheet of plywood is 32 ft2. For example, if the area to be covered in plywood is 800 ft2 then 25 sheets of plywood will be needed to cover it. Lumber and plywood prices are so high now because of the short-run […]

How do I calculate roof removal?

What is a roof takeoff? A roof takeoff is a report that provides a full list of the materials needed to complete your roofing project. … Roof takeoffs are a necessary requirement to having an organized and successful installation. How do I calculate roof removal? On the roof plan, measure the distance from the line of the ridge to the outside of the fascia, which […]
