TAKE-OFF LIST
Takeoff list is the most required components of any of project. They gives both the client and
the contractor the outline of the total material cost required for the contract. Takeoffs varies from
simple to complex depending on the size and scope of the project. Due to its importance of cost
estimation, this article sheds light on how a construction takeoff is crafted and the core
components of takeoff are, and what some factors are you should consider when creating that
takeoff.
Carpentry estimate sheet is also used in the estimation of both the exterior and interior framing,
cabinet and finishes of carpentry. To determine the rough estimate the materials to be used are
listed first with their functions and the parts in which they are used and then calculation is done
to get the estimate quantity.
Below is a take-off of carpentry framing of the interior walls of the garage of Huron County
Ambulance Station encompassing Rooms 100 including all the walls.
Requirements
1. Stud framing
This is the vertical frame in a building of the wall with a small cross section than a post and they
are used to carry the vertical structural loads. They holds in place the windows, doors, insulation
and interior finishing. They are slender than posts and beams .They also fastened to the plates to
prevent the building from lifted off by severe wind and earthquake.
2. plywood sheathing
This is the layer of material attached to the frame of the roof, floor and wall assembled on the
residential and commercial construction.it is used to form the surface in which materials can be
applied. Plywood sheathing is made of layers made up of very thin ply or wood that are glued
together from the surface is made of hardwood while inside is of softwood.

3. Air Barrier
It is a membrane attached to control air leakage into and out of the building. It is an essential
component in a building enclosing the air pressure and ensures comfortable environment within
the building. It is divided into air barrier material, air accessories, barrier system, and air barrier
component and air assemblies. They takes a lot of forms which can be mechanically membrane,
self-adhered, fluid applied, closed cell medium and polyurethane.
4. Sill foam gasket
It is a polyethylene that provides a sealing against air leakage, insect intrusion and moisture
between the foundation wall and the sill plate.
5. Items incidental to the framing
These are the necessary requirement in carpentry but they do not require an illustration or
description because they are either used in small quantity or their price is relatively small.
Example of incidental carpentry items include nails, plywood gum and other tools used.
How to estimate framing materials.
Construction materials estimation starts with counting of the frame lumbers .for the wall we
count the number of stud, horizontal plates for both top and bottom of the wall and the number of
sheets of the required for the interior side of the wall.
The takeoff of carpentry construction is first done by sketching the wall frame and identify
overall height and length of the wall and sizes of opening like doors and windows. The following
is the interior plan of different section within the office.
1. Interior plans of different sections of the garage
The dimensions of the interior part of the garage that needs to be furnished is; length is 50.50
feet, width 36.25 feet and the height is 14 feet as shown in the diagram below.
