Innovative Delivery of Information to the Crafts

Use of two-sided isometric drawings results in a 16% improvement in installation speed. Other notable improvements include direst work up, indirect prep time down, and a reduction in errors. (RS327-1, p. 11)

When using the two-sided isometric drawings, craft with lower spatial ability—as measured by the card rotation (left) and cube comparison (right) tests—performed as efficiently and effectively as pipefitters with higher spatial ability. (RS327-1, p. 13)

Two-sided drawings result in a $33 return for every $1 increase for engineering costs. Gains from Investment were estimated by improvements observed from installation rates. The cost to produce the Two-Sided Isometric was considered, however the time saved to compensate labor and operating equipment outweighs the added investment significantly. (RS327-1, p. 14)
