Project Experience
One of the most important tools for an estimator is experienceDesire to improve capital cost estimating systems, tools, methodologies and practices. Data collection of project cost, schedule and scope information required in a structured formatMissing feedback loop during the execution phase in order to validate and/or improve

Broken feedback loop
Many reasons can be identified:Disconnects exist between project management, estimating, planning and cost control, due to a lack of understanding of each other’s need which could disrupt a proper feedback cycleThe cost control baseline could lack the level of detail required to evaluate for instance compensation events during execution

Synergy between Cost Estimating and Project Controls
It is time to establish synergy between Cost Estimating and Project Controls by working with pre-set visual performance indicators during project execution.
Should start by setting up a proper baseline conforming to all requirements of the stakeholders. Monitor project cost and schedule performance during Project Cost Control

What are important metrics?
Metrics used for quantitative estimating in order to determine the expected project quantities without having to involve a full design team to determine these quantities.For example:• Length of pipe per main equipment item : 150 m pipe / eq.• Number of fittings per length of pipe : 0,6 fitting / m pipe
![Page 18: Total Cost Management - Synergy between Cost Estimating and Project Controls](https://reader035.vdocument.in/reader035/viewer/2022070511/58a53ec41a28ab4f088b4feb/html5/thumbnails/18.jpg)

The purpose of this focus on cost metrics is to extend to cost engineering practices. By using these metrics and research findings, companies can improve their project and business results. These characteristic values will:• Support conceptual estimate• Support estimate reviews• Assess company performance against industry norms.• Support calibration and improvement of company tools and databases.• Improve asset cost evaluation and concept development
