Reducing Errors in the Design Office

 

 

Reducing Errors in the Design Office – Bill Kimber

 

How can we reduce the quantity and severity of errors in the design office? As much as 37% of project increases in cost and schedule can be traced back to changes in the original contracted scope.

 

A change in scope can been defined as; “an unexpected development that will change the requirements and results in cost growth and time extension.”

 

All Contract changes must be well documented using procedures that should already be in place. Procedures are designed to allow accurate documenting of project changes and the transmission of updated costs to the client for approval. The costs and terms are added to the original project documentation after client approval and become part of the amended contract.

SPED Tech Tuesday: Design of Expansion Loops

 

Design Quality Improvement – Bulletin 02 4/29/19 Prepared by – Todd Sisti, PE

 

Design of Pipe Expansion Loops

 

 

Quality Concern:

 

What is the practical range of axial pipe line growth that a designer should plan for in the design of an expansion loop?

 

  • In Case 1 below the expansion loop is absorbing up to 20” (10” per side) of pipe line growth without a resulting pipe stress problem.

  • In Case 2 multiple expansion loops are designed which absorb only 1” to 2” of axial line growth.

SPED Tech Tuesday: Auxiliary Pipe Supports - Consider the Cost

 

Design Quality Improvement – Bulletin 01 4/29/19 Prepared by – Todd Sisti, PE

 

AUXILIARY PIPE SUPPORTS – CONSIDER THE COST ($)

 

Quality Concern:

 

Auxiliary Supports are sometimes referred to as Engineered Supports, or Special Supports. Regardless of what you call them, these supports are custom designed for a specific application. Sometimes they are used as a gang support to support many lines, and other times they are custom to support a special pipe stress need. Regardless of the need, the support designer should consider the cost of the design of the support and plan for economics in design.
