Integrating Design to Fabrication Workflows

for Industrial Projects

Geoff Butt, BA, CETLead Civil Designer, Gemini Engineered Solutions

Adam TravisSr. Civil Designer, Gemini Engineered Solutions

� The fast-paced Design-Build part of the oil and gas

industry has typically used two types of design

software:

� one for producing civil engineering 3D models & drawings and

� a different one for steel fabrication 3D models & drawings

� This session will present a mid-sized engineering,

procurement, and construction management

(EPCM) company’s experience-based case for using

only Advance Steel to successfully produce both sets

of drawings.

Class summary

� The presentation will describe:

� The business case for the decision

� The transition process

� Lessons learned

� Recommended path for success

� We’ll conclude with about 5 -10 minutes of questions

and answers.

Class summary

At the end of this class, you will be able to:

� Understand the business case for using Advance Steel to produce both

civil engineering and steel fabrication drawings from the same model.

� Know the transitional steps for a civil drafting department to become a

successful contributor in a Design-Build company.

Gemini

Bakken Formation

� Work with other disciplines, mainly Plant Layout & Piping

(PL&P) and Electrical to produce engineering drawings.

� Our civil engineering deliverables include earthworks/roadworks, piling

and foundations, concrete, steel, and buildings.

� Work with our steel fabrication shops to produce steel

fabrication drawings.

� We usually receive Engineering Issued For Construction (IFC) drawings

from our own department, or from other Engineering consultants. Then we

produce steel Issued For Fabrication (IFF) shop drawings.

� Distinction between engineering and fabrication drawings

� Sincere apologies to those of you who already know!

Civil Design Department

general role and deliverables

� Engineering drawings:

� direct the fabricator in all design aspects, materials, coatings,

specifications, and governing codes.

� specify delegated connection engineering loading.

� provide just enough dimensions for the fabricator (minimize duplicated

dimensions).

� packages vary greatly in the amount of detail provided.

� almost never contain Mark Numbers.

� identify temporary members.

� identify erection and assembly constraints.

Main distinction between

engineering and fabrication drawings


� identify temporary members.


� identify erection and assembly constraints.

� Fabrication drawings:� always contain Mark Numbers.

� set includes erection, assembly, single parts, and Bill Of Materials (BOM).

� show every dimension (includes tolerances, and adjust to field measurements).

� should stand alone. The fabrication personnel should not have to refer back to the

engineering drawings. (This is more important on large projects, but the rule is

sometimes broken on small projects to save drafting duplication and cost).

� package can include numerical control (NC) files that are used by a machine’s

software to cut steel.

Business Case for why we use Advance

Steel to produce both engineering and steel

fabrication models and drawings

� Schedule

� Quality

� Cost

is primarily based on improvements in:

� SCHEDULE improvements:

� We produce one model to produce both engineering and fabrication drawings.

The advantages are that we:

� can advance the model to a fabrication level detail during the engineering modeling stage

when the designers have any kind of downtime.

� can engage our fabrication checkers to check the model earlier.

� do not have to take time to export the engineering model and import into the fabrication

software.

� don’t have to wait for the IFC drawings bid period, bids review and selection, and award.

� Sometimes we can actually start slightly before IFC is issued as long as the Engineering model is

deemed to be complete and released to the fab team.

Business Case for Advance Steel

� QUALITY is better because we:

� lower any chance of a discrepancy between the engineering model and the

fabrication model, because it’s the same model.

� have standardized the 3 types of fabrication drawings and BOMs using drawing

templates, so that each designer’s drawings have the same presentation.

� Library include standard assemblies and settings.

� Erection drawings are currently built by the designers, however assembly and single part

drawings are automatically generated.

� spend less time checking the drawings and more time making sure that the

model is perfectly correct.

� The checkers know which drawing items are automatically generated, and therefore should

be correct if the model is correct.


� COST is lower because we:

� do not have to create 2 models.

� do not have to take time to export the engineering model and import into the

fabrication software.

� have improved the automated standardization.

� spend less time checking.


Transitioning the Civil Design Department

to the new workflow

� Brief Description of our previous workflow

� Brief Description of the new workflow

� Working with other disciplines

� Working with our two remote fabrication shops

� Designer training

� Creating Advance Steel 3D blocks

� Customizing and automating drawing production


to the new workflow

� Brief Description of our previous workflow:

� Produced the model in CADWorx and then IFC drawings also in CADWorx

� Recreated the model in Advance Steel and then produced IFF drawings also in

Advance Steel

� BOMs required substantial checking time

� We did not have a beam profiler


to the new workflow

� Brief Description of the new workflow:

� Produce engineering model and drawings using Advance Steel.

� Make a copy of the same model to produce fabrication drawings using Advance

Steel.

� Automatically generate BOMs and nc files for the fab shop


to the new workflow

� Working with other disciplines:

� The other disciplines are currently using CADWorx.

� Our Advance Steel Model is xreffed in to the full model.


to the new workflow

� Working with our two remote fabrication shops:

� Fab shop representatives are invited to model reviews to verify constructability

and cost efficiency.

� Fabrication drawings are sent through our Document Control to the fab shops.

� nc files are sent up to the Fort Saskatchewan shop to feed the PythonX robotic

computer numerical control (CNC) plasma cutting system.

� Cut steel is also assembled and welded there, or trucked to our Ponoka fab shop.

� We have one designer on site in Fort Saskatchewan who:

� takes care of drafting standard products (ex. pipe shoes)

� adds heat numbers to the nc files (scribed on to the individual steel parts when required)

� trouble shoots any nc file issues at the PythonX.


to the new workflow

PythonX

� Designer training:

� We used a 30 hour Advance Steel basic course put on by Graitec

(www.graitec.com). It is offered online 3 hours/day over 10 days, which worked

best for most users. They had Advance Steel actual projects to work on for the

remainder of the day.

� We have also tried using Graitec’s trainer at Gemini over 3 full days. Users

found this more difficult to absorb.

� We had a half day course for the checkers using the Advance Steel read-only

version.

� We selected one designer for advanced training in order to be able to

customize and create templates. This consisted of 2 full days at Gemini.

� More courses are available, but the above is what we used.


to the new workflow

� Customizing and automating drawing production:

� Creating a block library of Advance Steel 3D objects

� Using templates to automate drawing production

� Erection drawing example

� Assembly drawing example

� Single Part drawing example

� BOM example


to the new workflow

� Creating a block library of Advance Steel 3D objects

� Block models are thoroughly checked for future use.

� Example of automated drawing production:

� Customizing and automating

drawing production


� Erection drawing example:


� Assembly drawing example:


� Single part drawing example:

Lessons Learned

� Advance Steel

� PythonX

� From the fabrication shops

� Designer training

Lessons Learned:

� Advance Steel:

� Research the available software options and get first-hand accounts of the

implementation process.

� Train and transition a spearhead team first in order to work through any issues.

� Put your best customizer through advanced training.

� Begin customization of blocks and templates.

� When the workflow and drafting system is proven to be more efficient than the

current system, then train the remainder of the operators.

� Put “click by click” instructions in a CAD Manual.

� Keep on top of any Advance Steel fixes and versions.

� Unfortunately it takes time to switch all the software versions over to 2015, especially if

some of them are not previously tested for compatibility by Autodesk.

Lessons Learned

� PythonX:

� See the CNC machine in action and know what issues crop up.

� Visit a fab shop that is using the brand of CNC machine you want, and that has its own fab

drafting department. Ask the manager, machine operator, and designer(s) what issues they

had to face and how they overcame them.

� Train each designer regarding what each line of nc code does.

� If you cannot resolve a file, send it to the machine’s help desk.

� In our case, Burlington Automation

� We get back redmarked files with an email explanation of what was wrong.

� Train each designer regarding what each line of nc code does.

� If you cannot resolve a file, send it to the machine’s help desk;

� in our case, Burlington Automation.

� We get back redmarked files with an explanation of what was wrong.

� Document every problem and its resolution.

� Start a file structure for storing repeatable standard products (ex. pipe shoes).

� Categorize by product, and by client for client-specific requirements.

Lessons Learned

� From the fabrication shops:

� Know their workflow and drawing requirements. Every shop is different; for

example:

� Crane capacity affects size of assembly that can be flipped for welding from above.

� Rat holes can be drafted and nc sent to the PythonX, or cut at the fab shop. What do they

prefer?

� Visit the shop floor and ask what they like and do not like about the fab

drawings.

� Where they have a choice of handrail type, what connections are the most cost-

effective and best?

� For example they prefer flat plate midrail versus an angle.

� Advance Steel renumbers Mark Numbers (ex. for re-issue of revised items).

This can cause the fab shop a lot of confusion and extra work. “Lock down” any

part numbers that have been issued.

Lessons Learned

Measuring success

If you have integrated the new workflow correctly,

what does that success look like?

� Satisfied internal and external clients

� Schedule

� Quality

� Cost

� Designers’ morale

Measuring success

� Satisfied internal and external clients:

� Usually on time, error-free, and under budget does the trick!

� Let it be known up front that feedback is requested

� Track Lessons Learned along the way and conduct a Lessons Learned review

at the end. Action any improvements needed for the next project(s).

� Communicate any improvements learned for the next project(s) with the fab

shops and the client as needed.

Measuring success

� Schedule:

� Start an IFF drawing deliverables schedule before the IFC engineering

drawings are even provided, and keep it up to date.

� Communicate any IFC potential date slippage with all concerned.

Measuring success

� Quality:

� Drafting memos are distributed to all so that not just one designer learns.

� New items get put into the Civil Department’s CAD Manual.

� Quality concerns are also discussed for resolution at monthly civil designers’

meetings.

� Regular checkers’ meeting to resolve any differences in checkers’ redmarks.

� We escalate any problem issues

� Important to have an escalation path that every designer knows

� Our own CAD Support

� Advance Steel issues go to our in-house guru, then to Graitec and Autodesk

� PythonX issues go to Burlington Automation (24 hr hotline, or email for less time-sensitive)

Measuring success

� Cost:

� We track all fab project drafting hours with kg of steel per hour of drafting.

� Steel can be categorized into light, medium, heavy, and extra heavy.

Measuring success

� Cost:

� We keep standard estimating spreadsheets with typical hours per unit

(ex. a tank base). We multiply that by both a complexity factor and

quantity of tank base types.

Measuring success

� Designers’ morale:

� Standardization and bug removal (or work-arounds) is key.

Measuring success

� Designers’ morale:

� Must communicate expectations

� Show estimates to the designers and obtain agreement that they are achievable.

� The above results in quick communication when anything slows down a designer.

� Must communicate bigger picture and how designers are an integral part of

success

� Project drivers are important (ex. Schedule versus Quality versus Cost)

� Communicate the “why” for any change in priorities.

� Tracking productivity gives everyone a goal and purpose for improving.

Provides proof of success.
