What experience have they had? What can you afford to pay them? What have you to draw from? Areas to be looked at under this element are: a. Experience b. Supply c. Pay Like general economy this too must be carefully analyzed. If business is excellent, the chances are that you will have a poor lot to draw from. If business is normal, you will have a fair chance of obtaining good supervision.
The contractor who tries to cut overhead by using cheap supervision usually winds up doing a very poor job. However, the estimator has no control over this. It must be left to management. All the estimator can do is estimate his projects accordingly.
Are the craftsmen in the area experienced and satisfied? Are there adequate first-class craftsmen in the area? Like project supervision things that should be analyzed under this element are: a.
Pay xiii The area where your project is to be constructed should be checked to see if the proper experienced craftsmen are available locally or if you will have to rely on travelers to fill your needs. Can and will your organization pay the prevailing wage rates? Example: Let us say that for a project in a given area we have found our labor relations to be fair but feel that they could be a little better. Is the schedule tight or do you have ample time to complete the project?
What is the condition of the site? Is it high and dry and easy to drain or is it low and muddy and hard to drain? Will you be working around a plant already in production? Will there be tie-ins making it necessary to shut down various systems of the plant? Will most of your operations be manual or mechanized? What kind of material procurement will you have?
There are many items that could be considered here, dependent on the project; however, we feel that the most important of these items that should be analyzed under this element are as follows: a. Scope of work Site conditions Material procurement Manual and mechanized operations By careful study and analysis of the plans and specifications coupled with a site visitation you should be able to correctly estimate a productivity efficiency percentage for this item.

The instruments that are to be installed on the panel board or cabinet are usually furnished to the sub-contractor by the general contractor. Panel boards are usually fabricated in sections up to approxi mately 12'Q" in length.
Per linear foot of control board length 1. Mail hours for installation of air supply piping and air signal lines from control panel to remote instruments are not included.
See other accounts for these man hours. No manufacturer's representatives are included in the above man hours. Multipoint Temperature Indicator, per pt. Analog computer for multiplying two variables, or dividing one variable by a second one, or extracting square root of one variable, or squaring one variable 3.
Man hours for installation of air supply piping and air signal lines from control panel to remote instruments is not included. No manufacturers representatives are included in the above man hours. First of all, the area in which the pipe is to be installed must be excavated. Before an estimate is made on this item it is well to know the kind of soil that may be encountered. For this reason, we have divided soil into five groups according to the difficulty experienced in excavating it.
Soils vary greatly in character and no two are exactly alike. Group 2: Preliminary loosening is not required when power excavating equipment such as shovels, dragline scrapers and backhoes are used.
This earth is usually classified as ordinary soil and loam. Group 3: Hard and compacted loam containing gravel, small stones and boulders, stiff clay or compacted gravel are good examples of this type. Light blasting is often required when excavating with power equipment. Group 5: ROCK — Requires blasting before removal and transporting. May be divided into different grades such as hard, soft, or medium. For carbon steel pipe installation man hours refer to section two of this manual.
This too, has been covered with a table listing the direct man hours that are required for coating and wrapping various sizes of pipe. Oiler Labor 1. Oiler Labor Op. Oiler Labor 3. This must be added in all cases. Operation includes excavation and dumping on side line or into trucks for hauling but does not include hauling. See pages on hauling for this charge.

Add from respective pages for these charges. Man Hours Per Foot 0. It includes labor man hours for the installation of patented clevis, band, ring, expansion and trapeze types as well as fabricated hangers and supports made from structural angles, channels, etc. Thus, this becomes the estimator's problem for the purpose of bidding the job.
Field Erection: Fabricated Hangers Angles, Channels, Etc. The following factors should be applied for sizes over 4": We have not covered color coding under this section due to the fact that the scope of the work involved in this operation can vary so greatly. As an example,you maybe able to set-up in one location and band as many as a dozen lines, on the other hand the same set-up maybe required to band one line. Labor for scaffolding must be added.
Man hours to galvanize exterior and interior of pipe is approximately the same as dimetcote. Sections — 7' L x 5' W x 5' H Includes: Transporting scaffolding and materials from storage. Erection of scaffolding including leveling and securing. Installation of 2" planking.
Dismantling of scaffolding. Transporting scaffolding and materials to storage. This is due largely to the fact that this is a very special item which is usually subcontracted to an organization who specializes in this field. Too, an insulation contractor will consider many factors before he submits his bid — such as, "Do I want or need this job, is the job large or small, etc. However, we believe that for projects where much and varied insulation is to be used a contractor who specializes in this type of work should be consulted on this matter.
Outside Use: Use same man hours as appear above for this type insulation. This will include labor for butter joints with "Seal Koat" and secure with 16 and 14 gauge galvanized wire on 9" centers. Finish with one coat "Seal Koat" for indoor piping and 55 asbestos roofing felt secured with 16 gauge wire 6" on center over the layer of "Seal Koat" on outside piping. Above thicknesses and man hours are for all hot services, if calcium silicate is used.
The above man hours are for either indoor or outdoor service. Bent Pipe: Steam Traced Piping: To be man houred at size of pipe covering required to fit over pipe and tracer line.
Method of Measurement: Straight pipe to be determined by measuring along approximate center line over the exterior of the insulation from center line to center line of change of direction.
Measurement shall be made through all valves and fittings, except bent pipe. Pipe Covering: Molded sections secured with 16 ga. Outdoors with 55 Fiberock Asbestos Roofing felt secured with 16 ga. To be built-up with insulating cement or sectional pipe covering pointed up with asbestos cement, finished with 6 ounce canvas and Arabel for indoor service and "Seal Perm" for outdoor service.
Section Ten This section is presented for the purpose of showing the work ability of a few of the man hour charts as appear throughout this manual. It does not mean that a take-off must be made in this manner before the man hour charts will work.
It is merely a suggested method. We do not show in this sample estimate any material cost, nevertheless, you will find ample space provided for this item. You will also find space provided for both unit and total weights of pipe and fittings.
We feel that this item has much value such as an estimate check using the weight method, or for the estimation of warehousing, equipment usage and fabrication shop set-up. As is stated in the Preface of this manual, its sole purpose is for the estimation of direct labor in man hours only.
Jy IB O. Therefore, this section has been held to a minimum and includes only information that we feel will benefit the estimator in the preparation of his estimate. Included in this section are tables showing the circumferences of pipes for welding purposes, the amount of materials needed for insulation, the weights of pipe, fittings and valves and methods of hanging and supporting pipe and fittings.
We wish to acknowledge and to express our appreciation to the Grinnell Company, Inc. M- A A. A A. The weight of reducing fittings is approximately the same as for full size fittings. The weight of Welding Reducers is for one size reduction, and is approximately correct for other reductions. Pipe Covering temperature ranges are intended as a guide only and do not constitute a recommendation for specific thickness of material. Pipe Covering thicknesses and weights indicate average conditions and include all allowance for wire, cement, canvas, bands, and paint.
The listed thicknesses of combination covering is the sum of the inner and the outer layer thickness. When specific inner and outer layer thicknesses are known, add them, and use the weight for the nearest tabulated thickness. To find the weight of covering on Fittings, Valves, or Flanges, multiply the weight, factor light faced sub script by the weight per foot of covering used on straight pipe.
All Flange weights include the proportional weight of bolts or studs required to make up ail joints. Lap Joint Flange weights include the weight of the lap. Welding Neck Flange weights are compinsated to allow for the weight of pipe displaced by th flange. Pipe should be measured from the face of the Mange All Flanged Fitting weights include the proportional weight of bolts or studs required to make up all joints.
Weights of valves of the same type may vary because of individual Manufacturer's design. Listed valve weights are approximate only. When it is possible to obtain specific weights from the Manufacturer, such weights should be used. Wall Designation Thickness— In.
