Wall Costs - michigan.gov

1 This section is not a part of the Segregated Cost Method. It is pre-sented here to provide a detailed cost buildup where it is felt that aspecific wall being valued varies significantly from the typical wallson the Segregated Cost pages or where such detail is Costs in this section differ from the Segregated Costs ofSections SEG 1 through SEG 6 in that each individual wall compo-nent is priced separately, while the segregated wall Costs include, inthe one cost, an allowance for each of the following components:1.

2 BASIC WALL2. EXTERIOR COVER3. INTERIOR FACING4. FINISH (exterior and interior) 5. OPENINGS (windows and doors)Some walls will be made up of many component parts, while othersmay have only two or three. The examples, on the next page, illus-trate the method to use in building up a total wall cost. The Costs aregiven per square foot of actual area of the various componentsexcept as otherwise stated. Thus, if any component, such as win-dows or doors, does not occupy the total wall area, the unit priceshould be multiplied by the proportion of the area of the componentto the total wall area.

3 Costs include full allowance for the generalcontractor s overhead and profit. However, the architect s fee mustbe Costs are the sum of the Costs of all their parts. Basic wall costsfor wood frame, brick, stone, etc., and for wall coverings such asface brick, wood shingles, and many others, are priced for the entirewall area regardless of the number and size of openings. To thesecosts are added the unit Costs for windows and doors. These unitcosts are applied in the proportion the windows and doors bear tothe entire wall principle is demonstrated in the examples.

4 In Example 1, forinstance, where 10% of the total wall area consists of windows, 10%of the unit cost for windows is applied to the total wall are exceptions to the above rule. For instance, in the build-ing elevation illustrated in Figure A, the basic wall cost would beapplied only to the lower half of the wall which is shown and the win-dow Costs applied to the upper this type of wall and the completely blank wall, there is acomplete chain of gradations, which leaves much to the experienceand judgment of the B shows the front elevation of a typical industrial building.

5 Where the basic wall Costs are applied to the entire wall and the costof the windows and door is applied to the actual area of the so-called doubling of areas for computation, as in Figure B, pro-vides an allowance for the added cost of building the wall section can also be used to test the proper rating choice in theSegregated Cost section. For example, the assessor mayencounter a wall which is not typical either in the number of open-ings, type of interior finish, or some other feature.

6 He may profitablybuild up the cost of that particular wall in detail and not only use thecost for that particular appraisal, but also could use it as a guide inchoosing the proper rating number in the Segregated Costs when asimilar wall is encountered in the is sometimes desirable to build up the cost of interior partitionsinstead of pricing them on a square foot basis. Some of the compo-nent parts for interior construction may be priced from this section;however, interior doors and built-in cabinets should be priced fromSection UIP 5, PAGE 1 2003 - State of MichiganWALL COSTSEXPLANATIONF igure AFigure BFIGURE BFIGURE ACost per Square Footof Total Wall AreaBASIC WALL1.
