    Insulation Section

    Refer to All About Insulation Material for any questions regarding construction materials and processes related to this section

    Header Information

    Most of the information in this head can be pulled from the BasicInfo tab, or other places in the Estimating Workbook where it has been calculated previously. If a value is not present, enter formulae to reference those values, or use Bluebeam to study the plans and enter the missing values.

    Materials Subsection

    Line items in this subsection that require extra consideration outside of the process described in How to Complete Material Estimates:

    • All items should use LFQuantity and SFQuantity user defined functions to calculate quantity as is appropriate.

    Labor Subsection

    This is the same process used for estimating labor costs for any other construction task using the NCE.

    1. Ensure that the materials that correspond to each job description are present in the line items in the Materials Subsection.
    2. Use the NCE to look up the CraftHrs, Unit, and Labor for the specific job and material. 
    3. Reference any relevant information in the Header and Material Subsection to calculate the quantity of Labor required for the job.
    4. Ensure the Total cell has calculated the total cost for completing the job.

    Drywall Section

    Refer to All About Drywall for any questions regarding construction materials and processes related to this section

    Header Information

    SF Standard Drywall

    Pull this information from the BasicInfo tab, using a formula to account for interior walls with both sides covered in drywall, the area of exterior walls, and the area of the common walls.

    SF Water Resistant Drywall

    Building plans do not always show which sections of walls will require water resistant drywall, or green board. If this is the case, look at the floor plans in Bluebeam and identify any wall sections that will come in contact with water. Bathrooms that include a shower or tub commonly use water resistant drywall. Use Bluebeam to measure and calculate the SF of any wall portions in the floor plans that will be built with water resistant drywall.

    SF Fire Resistant Drywall

    Fire resistant drywall will normally be found on common walls between the main building and the garage. Use Bluebeam to measure and calculate the SF of any wall portions in the floor plans that will be built with fire resistant drywall.

    LF Outside Corners

    Outside corners of interior walls require the installation of corner beads to strengthen those corners. Door frames with doors installed do not require corner beads, as they are reinforced with the door frame itself.

    1. Identify and count all outside corners that will require a corner bead.
    2. Use Bluebeam to measure the height of all wall sections that will require corner beads.
    3. Calculate the LF of corner bead required by multiplying the various wall heights by the number of corner beads those heights require.
    4. Input the total LF of required corner bead in the LF Outside Corners cell of the Drywall Materials Header.

    Materials Subsection

    Interior Trim Section

    Refer to All About the Framing Phase for any questions regarding construction materials and processes related to this section

    Header Information

    LF Interior Walls

    This information should be precalculated with a formula that will pull information from other parts of the workbook. If it does not, either write a formula to calculate this value, or use Bluebeam to complete a takeoff.

    LF Interior Walls W/O Baseboard

    Some walls will not require finishes like baseboards. Examples include wall sections with built-in cabinets, vanities, or appliances, stairways, and bathroom fixtures like tubs.

    1. View the overhead floor plans and elevation floor plans in Bluebeam to identify any wall sections that will not include baseboard trim.
    2. Use Bluebeam to complete a takeoff measurement of all wall sections without baseboard trim.
    3. Add all the measurements together to estimate the total LF of wall sections without baseboard trim.
    4. Enter this measurement in the Interior Trim Material Header for LF Interior Walls W/O Baseboard.

    Note: Toilets are not typically built into the wall, so baseboard trim is likely to be installed behind it.

    LF Door Openings

    Door openings typically include a door frame and door casing that does not require the use of baseboard molding. Because of this, the LF of all door openings must be subtracted from the total LF of interior walls to accurately estimate the quantity of baseboard molding required.

    1. View the overhead floor plans and elevation floor plans in Bluebeam to identify any door openings that include an actual door.
    2. Use Bluebeam to complete a takeoff measurement of the width of all door openings that include a door.
    3. Add all the measurements together to estimate the total LF of door openings.
    4. Enter this measurement in the Interior Trim Material Header for LF Door Openings.

    Note: Some building plans include archways without doors. These are typically trimmed with baseboard, so do not include any of these openings in your door opening count.
