Housekeeping

Housekeeping is something we all grow up with. Some learn it better than others. On the job site, we all must practice good housekeeping because it affects safety and productivity. There are three main housekeeping issues: job site scraps, personnel debris, and tool organization.

Job site scraps are the cut-off ends of pieces of wood, lumber torn down that will not be used again, wrapping from lumber, empty nail boxes, and numerous other materials brought onto the job site that will not be used. You don’t always want to take the time to attend to this debris at the moment it is made, but you do need to make sure that it is not left in a location that would pose a safety problem,

such as in a walkway or at the bottom of a ladder...

EXAMPLES OF SUCCESSFUL VE HIGHWAY STUDIES

To recognize outstanding VE achievements and promote awareness of the importance of this program, the AASHTO Value Engineering Task Force has established national awards to be given to state transportation agencies. These awards are presented every 2 years to agencies that have shown special achievement in either cost-effectiveness or innovation.

STRETCHING CARPET

Once the carpet seams have cooled, stretch and attach the carpet to the tackless strips around the perimeter of the room, using the knee-kicker, power stretcher, and stair tool. Actually, if you must join carpet seams, you already will have used the knee-kicker to draw the carpet edges taut so the glued seam will be a straight.

Typically, stretching begins in a corner, using a knee-kicker. Place the knee-kicker about 1 in. from the wall and rap the cushion of the tool

Подпись: 9. After stretching a carpet, use an edge trimmer to cut off the excess around the perimeter of the room. Then use a stair tool to tuck carpet edges behind tackless strips or under baseboards. That’s pretty much it. Once the second corner is attached, alternate using the knee-kicker and the power stretcher, somewhat as shown in "A Carpet-Stretching Sequence,” below. There’s no one always-best sequence. Keep an eye on what the carpet is doing, and use the tool that seems right...

METHODS OF CALCULATION

The concepts of annualized cost and present worth are employed in LCC. Using the annual­ized cost method, all costs incurred are converted to equivalent annual costs using a base­line and a specified life span. For example, initial costs would be amortized over the life cycle and include principal and interest (similar to home mortgage payments). Replacement costs or rehabilitation costs at various points during the life cycle would also be converted to equivalent annual costs (sinking fund). The following steps can be employed:

1. Annualized initial cost. Tabulate all initial (acquisition) costs. These include the base cost of each of the alternative systems and any other initial cost. Total these ini­tial expenditures to arrive at the total initial cost (IC)...

CATEGORIES OF COSTS

Costs that must be considered depend to some extent upon the system or project analyzed,

but can generally be categorized as follows:

1. Initial costs

a. Item costs. These are costs to produce or construct the item.

b. Development costs. These are costs associated with conducting the value study, testing, building a prototype, designing, and constructing models.

c. Implementation costs. These are costs expected to occur after approval of the ideas, such as redesign, tooling, inspection, testing, contract administration, train­ing, and documentation.

d. Miscellaneous costs. These costs depend on the item and include costs for owner-furnished equipment, financing, licenses and fees, and other one-time expenditures.

2. Annual recurring costs

a. Operation costs...

ACCORDING TO A SURVEY in Builder

Magazine, Habitat for Humanity is the

15th largest house builder in the U. S.

a Since its founding in 1976, Habitat for Humanity has built or rehabilitated more than 40,000 houses throughout the U. S.

^ More than 350 Habitat houses have been built by all-women crews.

a According to The Chronicle of Philan­thropy Habitat for Humanity is the 23rd largest nonprofit organization in the U. S.

a The average Habitat house built in the U. S. costs just over $48,000, encom­passes 1,100 sq. ft. of living space, is held together with 20,000 nails, contains 650 pieces of lumber, and is finished with 40 gal. of paint.

a Habitat for Humanity has 1,621 affil­iates in the U. S. (including Guam and Puerto Rico) and 497 international affiliates in 83 countries.

Chronological Table

[1] Sanlaville (1996).

[2] For a recent synthesis of the birth of agriculture and the Neolithic revolution, see the book of the pre­historian and archaeologist Jacques Cauvin, Naissance des divinites, naissance de l’agriculture, la revo­lution des symbols au Neolithique, revised in 1996.

[3] Some have proposed that population pressure explains the exodus which clearly accompanied the Neolithic spread (each generation seems to have migrated 20 kilometers or so). But according to Jacques Cauvin, this explanation is inadequate; he sees in addition a profound change of mentality, responding to the call of the “new frontier”.

[4] According to Geyer and Besanfon (1997), the Euphrates was in a sedimentation phase until the VIIth millennium BC, having a braided morphology which favored ea...
