The factors fp and fj have not been applied to installation costs because installation costs are not a simple function of purchase cost. Although process piping and fittings made for the same unusual conditions are proportionally more expensive, labor, foundations, insulation, etc. are not. Furthermore, only about 70 percent of piping is directly exposed to process fluid. The balance is auxiliary or utility piping made of conventional materials. 

Including 20 ft2 for miscellaneous items not identified in this section, 110.3 ft2 must be rented, at an annual cost of 44,100/yr. Note that this moderately sized complex is added to an existing electronic materials manufacturing facility. Hence, no direct charges are added for infrastructure, such as non-clean room and office space. The total purchase cost, 6,492,100, provides equipment modules that require small installation costs, on the order of 1% that is, 65,000. Note also that two PECVD reactors are provided to assure uninterrupted operation when the plant is in operation, around the clock, 330 day/yr. While the robot loads and unloads one of the reactors, the other reactor is in operation. 

The total M + L, material and labor cost, is shown in Table 8.12 as a direct cost factor, 231.3. This is a percentage-type cost factor, a percentage of the total base cost. All materials of the fabrication shop and field materials are included. Labor in both the fabrication shop and field are equally included. Thus, this single figure in Table 8.12 is a factor for deriving the total direct cost of a new shell/tube heat exchanger fabricated and field-installed, ready to commission. 

Although accurate costs for pipes, valves, and piping system auxiliaries can be obtained only by direct quotations from manufacturers, the design engineer can often make satisfactory estimates from data such as those presented in Figs. 14-3 through 14-34. The cost of materials and installation time presented in these figures covers the types of equipment most commonly encountered in industrial operations. 

The materials column includes all the equipment and materials usually purchased by the Owner and/or general contractor - to be installed by the subcontractors. The subcontracted labor column includes all costs, direct and indirects, incurred by the subcontractors for the installation of these materials. Construction equipment rentals as well as contractor overhead and profit must also be included. The accounts traditionally treated in this manner are ... 

Enter the size parameters and then click the Evaluate button, shown in Figure 6.3d. This runs the evaluator program and gives the results screen shown in Figure 6.3e. The purchased equipment cost is 145,900 on a January 2006 USGC basis. The installed cost is 196,225. Note that the installed cost is calculated directly by estimating bulk materials and labor rather than using an installation factor. 

Power requirements and materials are directly related to the size of the treatment area. One of the largest unit cost factors is the depth of the contamination. This variable may be more sensitive to Lasagna-type installations and direct-push installations than borehole or well-based installations. Project costs tend to rise more than linearly with depth. Power and materials rise linearly with depth, but the installation labor costs and, possibly, equipment cost may rise more than linearly as time required to install and horsepower can increase significantly as depth increases, especially beyond 15-25 m. It may take longer to drill the boreholes or drive mandrel systems to depth because of soil changes and the increase in soil densities. 

Step 3 Update the cost data to the current cost index. For each piece of equipment, determine the bare-module cost, using bare-module factors, Fbm, from Table 16.11, being careful to determine it properly when the material of construction is not carbon steel and/or the pressure is not near ambient, as given by Eq. (16.12) and illustrated by the following example, before moving to Step 4. As discussed earlier, the bare module cost accounts for delivery, insurance, taxes, and direct materials and labor for installation. 

As shown below, the List of Equipment and Bulk Material by Area portion of the report is displayed when the Equipment List is accessed. This provides the Purchased (Equipment Setting) and Installed Direct Costs (i.e.. Total Material and Manpower Cost or Total Direct Materials and Labor Cost) for each piece of equipment, e.g., the reboiler as shown next. Note that the right-hand window below is displayed using a 7-point font. This is achieved by pressing the Select Font button on the toolbar. Furthermore, portions of the complete printed output are provided in Appendix HI of these notes. 

The total direct material and manpower costs for construction of the plant are 605,400 and 152,100, as shown in line 11. These sum to 757,500 and include items that cannot be charged to the individual equipment items (e.g., charges for instrument testing, pipe testing, and equipment grounding). Note that the installed costs of the equipment items are displayed on the List View ... 

The installed costs sum to 646,800 that is, 108,700 less than the total direct cost of materials and manpower for installation of the plant, 757,500. This Installed Direct Cost, Cdi, is referred to in Chapter 16 of the textbook as the Total Direct Materials and Labor Cost, Cdml- Finally, the materials and manpower items that are not chargeable to the individual equipment items are displayed in the Area Bulk Report within the Capital Estimate Report ...

If this equipment cost were multiplied by the bare module factor for the base case, the cost would become ( 43,880)(3.29) = 144,360. This is 16% greater than the 124,490 calculated in Example 7.11. The difference between these two costs results from assuming, in the latter case, that all costs increase in direct proportion to the increase in material cost. This is far from the truth. Some costs, such as insulation, show small changes with the cost of materials, whereas other costs, such as installation materials, freight, labor, and so on, are inpacted to varying extents. The method of equipment module costing accounts for these variations in the bare module factor. 

Shallow holes that are used for temporary deployments are typically not cased. This minimizes the cost of the installation. A seismometer deployed in an uncased hole is backfilled with sand or the excavated materials from the hole. This type of deployment is also known as a direct burial installation. A direct burial installation is quicker and easier to install than an installation using a vault seismometer. It is often challenging leveling a vault seismometer in a field deployment since it requires a hard surface, access to the leveling feet, and bubble level. With a posthole seismometer, the procedure is to dig a small hole, place the seismometer in the hole, backfill with earth or sand, and start the autoleveling in the seismometer. There is no further work required to insulate or weatherproof the installation. 

Fixed charges on capital investment. Dircd construction costs. The estimated costs of equipment, installation of equipment, and construction are based on the plant layouts for the two reference designs evaluated in this study. Construction and erection costs of all items, as well as direct materials costs for those components manufactured by the Babcock Wilcox Company, were developed by B W estimators. Delivered costs of equipment supplied by manufacturers other than B W were taken from vendors quotations.
