A system is an interconnected set of elements that is coherently organized in a way that achieves something. If you look at that definition closely for a minute, you can see that a system must consist of three kinds of things: elements, interconnections, and a function or purpose.

Most Schedules Are Built to Install Things.
Commissioning Schedules Are Built to Prove Them.

This is where the schedule stops tracking progress and starts delivering performance.
Where tasks turn into systems — and systems turn into handover.

Yet most planners still treat commissioning as an afterthought.
They try to tack it on instead of building it in.

That’s why commissioning schedules fail.
And it’s exactly why great schedulers stand out.

Here are 6 ways to get commissioning right — especially in P6:

1. Shift from Sequence Logic to System Logic
Construction logic follows areas and trades.
But commissioning logic follows systems.
You need to build the schedule around functional groups — HVAC, fire alarm, chilled water — not floors or work packages.
This is a logic transformation, not a sequencing tweak.

2. Start With the System Turnover Plan
Before you build commissioning activities, map your System Turnover Packages.
What has to be installed, tested, and approved before System A is ready for turnover?
This becomes the backbone of your logic — and drives the real float paths that matter to your client.

3. Integrate Commissioning Into the Baseline
Commissioning activities shouldn’t appear when construction is 90% done.
They need to be visible from the beginning — in the baseline.
When commissioning is part of your original critical path, you drive better coordination, earlier planning, and fewer surprises.

4. Use P6 Activity Codes for System-Level Clarity
Commissioning needs smart filters, not endless scrolling.
Use Activity Codes to sort by:

System or Subsystem
Commissioning Phase (Pre-Functional, Functional, Acceptance)
Turnover Package

This makes it easy to group, filter, and report what really matters — what’s ready to test, energize, and hand over.

5. Be Intentional With Constraints
Yes, commissioning depends on permits, documents, and inspections.
But don’t overuse constraints like Mandatory Start or Finish On.
Always lead with logic.
If you need a constraint, log it with a notebook entry — and always check your Schedule Log to catch float killers early.

6. Add Interface Milestones for Key Handoffs
This is the detail that sets great commissioning schedules apart.
Create milestones like:

“System B Mechanical Complete”
“System B Ready for Commissioning”
“System B Functional Test Passed”

These make handoffs visible, drive accountability, and give your team shared targets to hit.

The goal isn’t to finish the work.
It’s to deliver a working system.
Commissioning isn’t a phase — it’s the proof that everything before it worked.

Make sure your schedule is ready for that test.

Upgrading Your Resume

Copy and paste this prompt into ChatGPT, Gemini or Claude.

Act like a senior hiring manager and resume optimization expert with 20+ years of experience in the construction and engineering industry. You specialize in reviewing resumes for construction scheduler positions and providing targeted, actionable suggestions to align resumes with job descriptions.

Your objective is to analyze a construction scheduler's resume and compare it against a specific job posting. Then, provide a detailed evaluation and personalized suggestions to improve the resume so that it aligns more closely with the job requirements, responsibilities, and preferred qualifications.

Use the following step-by-step process:

Step 1: Read the resume (provided within triple quotes) and summarize its key skills, tools, certifications, experience, and strengths in bullet points.

Step 2: Read the job posting (provided within triple quotes) and summarize the key requirements, responsibilities, tools, experience, and qualifications sought by the employer in bullet points.

Step 3: Compare the resume with the job posting. Identify:

Areas of strong alignment between the resume and the job description
Skills, keywords, or experiences from the job posting that are missing or underemphasized in the resume
Any outdated or irrelevant content in the resume that could be removed or revised

Step 4: Provide a detailed list of specific, actionable suggestions to improve the resume. This should include:

Sections to rewrite or reword (with sample rewrites)
Skills or keywords to add based on the job description
Formatting or structure suggestions to better showcase the applicant's strengths
Any achievements or metrics that should be quantified

Step 5: Provide a brief overall summary assessment that highlights the resume’s current strengths and its potential to be improved for this specific role.

Here is the resume: """[Insert resume text here]"""

Here is the job posting: """[Insert job posting here]"""
