Quick Answer: General Project Managers vs. Technical Project Managers - Which One Do You Need?
General Project Managers excel at scheduling, budgeting, and stakeholder coordination for standard construction projects. They're ideal for renovations, office builds, and straightforward commercial projects.
Technical Project Managers combine PM skills with engineering expertise in mechanical systems, vibration control, acoustics, and building codes. They're essential for:
✓ Manufacturing facilities with specialized equipment
✓ Projects requiring vibration/acoustic analysis (cleanrooms, precision manufacturing)
✓ Complex MEP coordination (pharmaceutical, food processing, semiconductor)
✓ Strict compliance environments (FDA, NJUCC, OSHA, cleanroom standards)
Rule of thumb: If your project involves technical systems where engineering judgment affects cost and performance, choose a technical PM. If installation errors could cost 15-20% in rework, technical expertise isn't optional—it's essential.
Cost impact: Technical PMs typically save 10-30% on complex projects despite higher fees (5-8% vs. 3-5% of project cost).
Not all project managers are created equal. While every PM handles schedules, budgets, and coordination, the depth of technical knowledge separates adequate project delivery from optimized performance—especially in manufacturing and industrial construction.
Choosing between a general project manager and a technical project manager with engineering expertise is one of the most consequential decisions in complex facility projects. The wrong choice doesn’t just affect timeline and budget—it can compromise equipment performance, violate compliance requirements, and create operational issues that persist for decades.
This guide explains the fundamental differences between general and technical project management, when each approach makes sense, and how to determine what your specific project requires.
What Is a General Project Manager?
Core Competencies
A general project manager focuses on the universal aspects of project delivery:
- Schedule management – Creating and maintaining project timelines
- Budget control – Tracking costs and managing financial reporting
- Stakeholder coordination – Communication between owners, architects, and contractors
- Contract administration – Managing agreements and change orders
- Risk identification – Recognizing potential project delays
- Document control – Organizing submittals, RFIs, and approvals

Making the Transition: When to Upgrade
Signs Your Current Project Needs Technical PM
Even if your project started with general PM, these indicators suggest you should add technical expertise:
- Frequent change orders for “unforeseen” technical issues
- Design-construction conflicts appearing during installation
- Contractor confusion about engineering intent
- Multiple RFIs requesting clarification on technical systems
- Equipment incompatibility issues during commissioning
- Compliance concerns raised during inspections
- Performance issues with completed systems
Action: Bring in technical PM as consultant even mid-project to prevent further issues.
How to Upgrade Without Causing Conflict
Options for adding technical expertise:
- Technical PM as Consultant – Keep general PM, add technical oversight
- Co-PM Structure – General PM handles administration, technical PM handles engineering
- Full Transition – Replace general PM with technical PM (if contractually possible)
- Engineering Consultant – Add specialist consultants (vibration, acoustics, MEP)
Most diplomatic approach: Position technical PM as “specialized consultant” rather than replacement.

Frequently Asked Questions
Can a general PM work with engineering consultants instead of hiring a technical PM?
Yes, this can work for moderately complex projects. However, coordination between PM and consultants adds communication layers and potential gaps. A technical PM integrates both roles, making real-time decisions without waiting for consultant reviews.
When this works: Projects with discrete technical challenges (e.g., one vibration-sensitive area in otherwise standard facility)
When technical PM is better: Continuous technical judgment needed throughout project lifecycle
How much more does a technical PM cost?
Technical PMs typically charge 5-8% of project cost vs. 3-5% for general PMs. On a $5M project:
- General PM: $150,000-$250,000
- Technical PM: $250,000-$400,000
- Premium: $100,000-$150,000
However, cost savings on complex projects (10-30%) far exceed this premium. The technical PM often pays for themselves plus adds substantial net savings.
Can a technical PM handle non-technical aspects as well as a general PM?
Yes. Technical PMs have all the same project management certifications and training (PMP, scheduling software, contract administration). The engineering background is additive, not replacing fundamental PM skills. Many technical PMs have 10-15+ years managing projects before specializing.
What if my general contractor says they'll handle the technical aspects?
Contractors focus on installation based on drawings. They typically don’t:
- Review design adequacy before bidding
- Validate equipment specifications
- Coordinate between design disciplines
- Ensure compliance with specialized codes
- Perform value engineering in owner’s interest
A technical PM represents the owner’s interests throughout the project, including during design when most cost-saving opportunities exist.
Should the technical PM have a PE license in the same discipline as the project?
Ideally yes, but related disciplines often work. For example:
- Mechanical PE is valuable for HVAC, plumbing, food processing, pharmaceutical projects
- Electrical PE is valuable for power-intensive facilities, data centers
- Structural PE is valuable for heavy equipment, seismic-critical projects
The key is relevant hands-on experience with the specific systems in your project type.
Can we start with a general PM and add technical PM later if needed?
You can, but this approach loses the primary value of technical PM: preventing problems during design. Most cost savings and issue prevention happen before construction begins.
Better approach: Start with technical PM, or at minimum have technical PM review designs before construction starts.
The choice between a general project manager and a technical project manager fundamentally comes down to project complexity and consequence of technical errors.
For standard commercial construction with routine mechanical systems, general PM provides excellent value. The lower fee is appropriate when engineering challenges are minimal.
For manufacturing facilities, cleanrooms, precision equipment installations, and projects with strict regulatory requirements, technical PM expertise isn’t a luxury—it’s essential project insurance. The engineering judgment to catch design errors before installation, validate equipment specifications, and coordinate complex MEP systems prevents cost overruns that dwarf the fee premium.
Key Takeaway: On complex projects, the question isn't whether you can afford a technical PM—it's whether you can afford not to have one.
The typical 10-30% cost savings technical PMs generate on complex projects mean they often pay for themselves while simultaneously reducing risk and improving performance. For New Jersey manufacturing facilities navigating NJUCC compliance, FDA regulations, or complex urban construction challenges, technical project management expertise is the difference between project success and expensive lessons learned.
