A reliable Engineering schedule requires more than just dates. Tt requires a profound understanding of the interfaces among disciplines, deliverables, and construction.
What a Planner Must Master
To support a project effectively, a planner cannot treat Engineering as a single "block." Planner must be able to map the complex relationships among:
Engineering Deliverables & Disciplines
Procurement and 3D Model Development
Engineering and Construction Needs
Man-hour Estimation & Resource Loads
Rework & Revision Management
When planners lack experience, they often simplify Engineering and Procurement to a much higher level than Construction. The result? Activities with long durations and
logics built on arbitrary Start-to-Start + Lag relationships.
The "SS + Lag" Illusion
Similar flaws methodology apply in Procurement scheduling. Long Durations without granular logic, the relationship between Engineering milestones and Procurement cycles becomes a guessing game.
Procurement Complexity
The Price of Low Detail
Baseless Lags:Lags are added arbitrarily just to force dates to look "right."
Flawed S-Curves:Progress curves become straight lines or entirely incorrect.
Last-Minute Drama:E&P delays are hidden until they impact Construction.
Impossible Analysis:Delay analysis and forensics become impossible to justify.
Blind Risks:Resource and risk management cannot be applied to E&P.
Loss of Credibility:The schedule loses value as it fails to reflect site reality.
