Arrangement drawings

The proposal shall eontain preliminary eross-seetional outline and arrangement drawings. 

General arrangement drawings with location and characteristics of terminal points,... 

STRATEGY For the electron arrangement, draw the Fewis structure and then use the VSEPR model to decide how the bonding pairs and lone pairs are arranged around the central (nitrogen) atom (consult Fig. 3.2 if necessary). Identify the molecular shape from the layout of atoms, as in Fig. 3.1. 

Lube oil system arrangement drawing including size, rating, and location of all customer connections. ... 

Electrical and instrumentation arrangement drawing and list of components. ... 

The HDS includes lists of equipment, instruments, cables, and cable identification, label schedules and instrument loop drawings of the signal installations. General arrangement drawings identify the location of the IPC displays, keyboards, cable routes, and marshaling cabinets. 

Preliminary equipment arrangement drawings and proposed layout of required buildings. 

Note A bid package for a lump sum contract must also include complete P ID s, equipment and piping arrangement drawings and a complete set of project specifications... 

Plot size - from plot plans and arrangement drawings. 

When applied to Phase 1 designs (complete P lD s and arrangement drawings), the quality of the resulting estimates could be as good as the conventional detailed estimates normally prepared by contractors at much greater expense. 

Piping - Use P ID s, Plot Plans, and arrangement drawings to develop take-offs as follows ... 

Definitive and/or appropriation type estimates can be developed in four or six hours with the information normally provided in a Phase 1 package, i.e., P ID s, equipment list, plot plans, arrangement drawings, and single line electrical diagram. 

As mentioned in Section H.l the activity breakdown for this example is based on the preliminary estimate in Appendix L that was prepared without the benefit of P ID s and arrangement drawings. This breakdown would be barely adequate for tracking the civil work - site, concrete, and steel erection. However, it is not detailed enough for use for tracking electromechanical work - equipment erection, piping, electrical, and instrumentation. 

Such details are only available when the estimate is based on P ID s and arrangement drawings, in other words, on definitive type-cost estimates. 

Since P ID s and Equipment Arrangement drawings are not available yet, piping and instrumentation information must be estimated with the preliminary procedures in Chapter 19. Painting and insulation can be estimated using a Lang Factor. ... 

For a Conceptual Estimate where P ID s and Arrangement Drawings are not available, heat tracing must be estimated as an allowance based on the available process and site information. 

Note For estimates based on take-offs from P ID s and Arrangement Drawings, a resolution allowance would be warranted at this stage. Resolution allowances would be from 5% to 30%, based on the design status. (See also Section 19.10 Adjustments. )... 

A semi-detailed estimate of the Insulation Account can be prepared when P ID s and equipment arrangement drawings are available to develop take-offs and apply the unit prices in Section 19.5... 

Discuss the safety precautions involved in the operation of the plant, and the procedure to be followed in starting the plant up and shutting it down. Develop the mechanical design of the reactor and prepare a key arrangement drawing, supplemented by details to make clear the essential constructional...
