P&ID, Redline Markups and As-Built Drafting

P&ID Drafting & Updates

We create and update Piping and Instrumentation Diagram drawings that clearly represent your process systems. Our team focuses on consistency, readability, and alignment with industry and client standards.

We support:

  • New P&ID drafting
  • Revisions and system modifications
  • Legacy drawing cleanup and digitization
  • Standardization across drawing sets

Redline Incorporation

Field changes need to be captured accurately and efficiently.

We take redline markups from your site teams, engineers, or contractors and convert them into clean, updated drawings. This includes piping, valves, and instrumentation updates—ensuring nothing is lost in translation.

Our approach emphasizes:

  • Clear interpretation of markups
  • Fast, reliable turnaround
  • Consistency with your standards
  • Ongoing coordination when clarification is required

As-Built Drawings

Outdated drawings introduce risk. We deliver as-built Piping and Instrumentation Diagram drawings that reflect what is actually installed in the field.

Using approved redlines and client inputs, we produce final documentation that supports operations, maintenance, audits, and future engineering work.

Deliverables include:

  • Fully updated P&IDs with all field changes incorporated
  • Verified instrumentation and tagging
  • Clean, quality-checked drawing packages
  • Ongoing support for documentation management

Fixed-Price Drafting Model

We offer a fixed-price model based on drawing complexity categorized as low, medium, or high.

One of the main feedbacks we have received from clients is the frustration with hourly billing since it can vary wildly based on the project and the engineers doing the work. This is why we are taking on the operational risk since we have strong faith in our team’s ability to deliver results efficiently and you can have a clear price for your budget.

For projects involving design work, complex interpretation, or transformation engineering, we also provide full engineering support under a separate, custom proposal to ensure the right level of technical oversight.

Our Hybrid Model

We have the support and standards of North America combined with the talent and cost effectiveness of India all controlled in-house for complete control of our processes. Our main offices are in Calgary and Houston, while the operations offices are based in Chennai and Pilani. 

The result is a cost-effective alternative to traditional large EPC firms—without the overhead or rigidity. Our prices are 30-70% less expensive and we have quicker turnaround times thanks to overnight support.

Send us a scope to quote on or book a meeting with our team to see if we’re a good fit for your company.

How it Works

Our sales team will work with you to set up your drafting standards with our team. You can share your drawings (DWGs) and PDF redlines so we can assess whether the files are high, medium, or low complexity. If native files are not available, the project will be billed separately at a fixed price as part of our technical drafting services.
