Estimating Construction Types

NOTE-- We retired the BidMagic construction estimating software program in 2001. It has been replaced by Goldenseal construction estimating software.

We still include this BidMagic estimating software program manual as a convenience for users of our older program. Many features are similar, in Goldenseal estimating.

Construction Type

The BidMagic construction estimating software handles four basic types of projects--New Construction, Additions, Gut/Rehabs, and Remodeling. Every bid that you create will fit into one of these construction types.

New Construction

Choose New Construction if you are building an entirely new structure from the ground up.

HINT: You can use this command even if there are existing buildings associated with the project, as long as the new structure does not touch the existing ones.

When working in Dimensions on new construction, everything will be treated on a 'whole project' basis. Measure wall lengths and floor areas from plan drawings, and ceiling heights from elevations. BidMagic will assume that every surface that you've entered will be built entirely new. It will suggest no demolition, repairs or rehab work.

NOTE: Occasionally a project with many different ceiling heights on the same story is best treated as a Remodeling project, even though it is entirely new construction.

Additions

Choose Addition as a construction type if you are attaching new construction to an existing building without making major changes to the existing building (except at the point of contact with the addition).

NOTE: If you are combining an addition with major work inside the existing building, choose Remodeling as a construction type. If doing only minor work on existing building , choose Addition, and add the work being done on the existing building into the dimensions that are affected by the work that is actually being done (see page 349).
When dimensioning an Addition, first enter the amount of contact between the old building and the new addition (see page 174).

Additions are treated on a 'whole project' basis. Measure wall lengths, floor areas and ceiling heights for the addition only. BidMagic assumes that every surface that you've entered will be built entirely new. It will treat the contact wall as a special case--you'll have the option of doing demolition there, and that wall will receive new wallboard on only one side (the former exterior surface).

Gut/Rehabs

Choose Gut/Rehab as a construction type if you are making a major overhaul to most or all of an existing building. This choice works best if you are completely redoing a distinct chunk of the building, rather than a scattering of surfaces here and there.

NOTE: If the surfaces to be worked on are scattered, or if you are combining an Addition with a Gut/Rehab, choose Remodeling instead.

The BidMagic estimating software treats Gut/Rehab projects on a 'whole project' basis. Enter the floor area that will be worked on, the length of all walls being worked on, and the ceiling height for each story that is actually being gutted and rehabilitated.

BidMagic assumes that each surface you have entered will be finished with new wallboard, paint and trim. Enter the quantities of demolition and new framing independently, since Gut/Rehab projects often involve a mixture of wall removal, new framing and refinishing of existing walls. No exterior work is assumed for a Gut/Rehab project.

Remodeling Projects

Choose Remodeling as a construction type if your project can't be considered as a simple New Construction, Addition, or Gut/Rehab project. You can also choose Remodeling if you want to enter each room individually, even if the project could fall into one of the other categories.

NOTE: You may want to choose Remodeling for a project with many different ceiling heights, since you can set them independently for each room.

When dimensioning a Remodeling project, first enter the number of rooms you'll be working on (see page 175).

Unlike the other construction types, remodeling projects are handled 'room by room' instead of as a 'whole project.' You'll enter information about each room individually, rather than measuring overall floor areas and wall lengths.
In a Remodeling project, each wall between two rooms is covered on two separate room cards. The Room card for each room handles the wallboard, paint and trim on that room's side of the wall. The framing and insulation can be entered into either room card.

WARNING: Since wall framing can be entered into either of two rooms, be careful to enter it only once!
