  • From Missed Details to Valuable Lessons – A Take-Off Journey at UTAS Stadium Redevelopment

    From Missed Details to Valuable Lessons – A Take-Off Journey at UTAS Stadium Redevelopment

    Scope of the Project

    We were initially requested to prepare a material take-off and model for the UTAS Stadium Redevelopment project. The scope clearly included handrails and balustrades for multiple areas.

    Jobs like this are inherently more complicated than standard steel take-offs. They often require:

    • Detailed coordination between architectural and structural drawings
    • Consideration of site-specific conditions, such as existing structures that may need rust removal and recoating
    • Identification of non-typical items like steel grating over EAs, which may only be mentioned in notes—not shown in drawings
    • Understanding what is in scope and out of scope, especially for existing vs. new elements

    Example: In other jobs like Respect Care Avonlea, the scope required rust removal and recoating of existing steel. These unique elements must be clearly marked as in or out of scope so the person quoting knows how to price it.

    Also, it’s important to remember that not all steel items are drawn with lines. Some only appear in notes.

    Initial Submission & Review

    Our team submitted the initial take-off. However, during review, Mr. Koshy pointed out that handrails and balustrades were missing.

    👉 This was a valuable reminder that some clients require these items, especially when they’re a focus of the job, while others may choose not to quote on them. Knowing what matters to each client is essential.

    Given that this take-off was for quoting purposes, accuracy was vital. Even a small oversight could result in:

    • Financial miscalculations
    • Client dissatisfaction
    • Loss of trust or future jobs
    • Reduced team incentives

    This feedback helped us pause, reflect, and improve our approach for the future.

    Why Accuracy Matters in Take-Offs

    This wasn’t just a drawing task—it was a cost-based take-off used for budgeting and quoting. An error in such cases can:

    • Lead to incorrect cost estimations
    • Affect the project’s financial feasibility
    • Create production issues if the quote is rejected
    • Ultimately impact our credibility and incentives

    Moreover, certain items – like balustrades, stairs, and grating – are intricate and time-consuming to fabricate. These should not be quoted on a tonnage basis. It’s important to flag such elements to clients so they can be quoted separately and priced appropriately.

    Issues with the Take-Off

    Further review revealed that purlins and bridging members were missing. These were likely deleted during the cleanup process (e.g., using OVERKILL) without a proper post-cleanup check.

    A senior detailer shared three essential lessons that helped us improve:

    1. Double-Check After Cleanup

    Tools like OVERKILL are useful for removing duplicates, but they can unintentionally delete important steel items.

    Always:

    • Check the model space thoroughly after cleanup
    • Re-import or re-check structural drawings to confirm all members are intact
    • Visually verify all key components before finalizing the take-off

    2. Understand the Scope Clearly Before Starting

    Don’t jump into modelling or marking up without:

    • Carefully reading the client’s request and job brief
    • Noting special requirements such as rust removal, coatings, or integration with existing structures
    • Identifying what’s included/excluded from scope (e.g., stairs, handrails, balustrades, fixing brackets, grating)

    3. Follow Disciplined Modelling Practices

    A clean and organized model helps avoid confusion. This includes:

    • Using correct layer management
    • Extending beam lines to column blocks or grids
    • Using proper naming (e.g., RODXX for rod members in schedules)
    • Keeping the model aligned with architectural and structural references

    Key Learning Points

    We’ve compiled the following key tips from this project and past experiences:

    • Check material grades (e.g., use G450 for purlins and bridging if noted).
    • Always read both structural and architectural notes—some items exist only in notes.
    • Compare drawings -they may not match exactly.
    • Mark PDFs clearly during take-offs to show what’s included.
    • Flag special or intricate items like stairs, balustrades, grating – these are not suited for tonnage pricing.
    • List all exclusions clearly.
    • Mention that take-offs are rough estimates, and clients should verify quantities.
    • Follow consistent modelling practices for clean reporting and review.

    Key links:

    Please supply checklist and special notes with every take off report you complete.

    What is the purpose of an MTO?

    • The purpose is to enable our client to quote on a job. These structural steel jobs are expensive, ranging between $2m – 30m dollars. They employ us to do a “take off” i.e. to count the steel elements to enable them to quote, accurate.
    • If you make a mistake, then you could potentially cost our client millions of dollars. It is especially important that you DO NOT miss anything which should be in your take off.
    • Clients typically price their job based on tonnage of steel. i.e. $x / tonnge. if there are 100 tonnes, then they would quote: $x * 100. However, pricing on steel tonnage is not always accurate. Some jobs may require a lot of site welding. This requires a higher price. It is cheaper to do work in a factory than on a construction site.
    • Some items SHOULD NOT be quoted on a tonnage rate. For example: balustrades and stairs. Why? Because these items require a lot of work: they are intricate, and should not be quoted on a tonnage rate. Another example is grating. Therefore we must warn our client if there are special items, so that these may be priced separately.

    The Actual MTO report:

    • Please provide two MTO reports:

    (a) Full Material List

    (b) The second: Excel – Material List – which shows all sub-totals.

    (c) IFC file.

    (d) db1 file

    (e) and if applicable, your .dwg line work file.

    1. Where to save the .xls.rpt files? Ssave it to the appropriate file in your Tekla Program directory. In my computer it is here: C:\Users\All Users\Trimble\Tekla Structures\2023.0\Environments\Australasia\General\common_reports

    You’ll have to go into the file and add/edit fields if applicable.

    Please make sure that you do not double count “sub-totals” in the sub-total report otherwise you will get an incorrect tonnage report.

    • Read the report: (i) is there anything with a zero weight?

    If so, you have probably used the wrong “material” or grade. Is there anything obvious?

    • I want the files format in .xlsx (if possible)

    Why? Because when the client opens up .xls files they complain about some error. If you are using LibreDocs then please open your .xls file and save as .xlsx:

    If you are using Excel, the please open Excel and save the file as .xlsx (one with and without.with an ‘x’ on the end of it).

    Are you using Open Office or LibreOffice?

    • Combine MTO and MC Reports in the same email

    If I’m dealing with 10 projects then I have to coordinate 20 different emails. NO. I want them all together.

    Separate Areas – Do Separate Reports

    • e.g. You may have a main building, and a bike shed near the building – combine them into separate reports, so that fabricators can quote for them separately.

    Provide Screenshots

    • to make it easy for your clients.

    Bridging Report

    • I need separate bridging report.
    • Include the bridging in the “overall” report.

    On Refurbishment Jobs – make special notes

    • These jobs are extra complicated, require a great deal of coordination (plus site measurements). Make special note of the difficulties inherent in such jobs:

    Respect Care - Avonlea

Special notes to your client who is quoting.

    (This was for Respect Care Avonlea). Note: they want the EXISTING steel frames to have rust removed and recoated. Make such items clear for the person quoting – that this is to be in or out of scope.

    Check architectural and sturctural drawings and note discrepancies

    • Sometimes architecturals and structurals don’t match. They might miss steel e.g. frames.

    Check The Notes for Steel and / or other extra items items

    e.g. see below – we need steel grating over EAs. Please make sure you don’t miss such notes.

    • Not all steel is drawn with a line. Some steel is contained in a note. See example on Mt Atkinson structural drawings (page 13).
    • When doing take-offs and marking pdfs – make sure to mark the pdf so that the reviewer can see that you have accounted for the steel in the markup.

    Please quantify the exclusions in your report to give some basic idea on what the client needs to price. Please tell the client that your numbers are rough estimates and the client should verify independently – because we are not actually modelling those items.

    2025-06-18 – Clients are quoting steel. Help the clients establish what is and is not in their scope. e.g. while you might EXCLUDE e.g. lintels in your modelling, you must provide a note saying to the client that LINTELS exist if they exist. This goes for ANY steel in the job. e.g. a special steel door, or grating – if they are excluded from your take off, you must still provide a note saying we haven’t modelled it, and if possible, to provide an estimation of it.

    Add In Finish on Beams

    MTO STEEL FINISHES – this is a part of take-off:

    1. Primer only
    2. Painted ( usually only for metal works ) we do not do Metal works mto
    3. Fire rated (Intumiscent or Vermicular)

    These finishes must go on the member finishes

    1. Also when taking the snap shot, Each finish must have different color. There is already a method to render with steel finishes
    2. Different colors must be present on IFC files.

    If in doubt – ask.

    How to do bridging / purlin reports

    Add Status For quote:

    • Type in the quote number to get to the material_take_off page.
    • Add in the ETA date.

    Invoicing:

    • When you finish a job – I need to create a “variation” with hours 0.
    • In the “description” add in the following: (I) tonnage, and (ii) a google drive link to where your MTO reports are. This is for invoicing purposes – so the client can check our reports, and whether the details are correct.
    • Mark it as “IFA” or ready to invoice.

    Example of what to write on the “variation” on the MTO:

    • 27.3 Tonnes
    • Proof: Link-to-google-drive

    Code via .dwg file

    The source code + documentation is located here. (Sorry only accessible to Tek1).

    We will be regularly updating the code, and documenting how we do material take offs.

    List all files in the MTO:

    1. Go to the relevant folder in Windows File Explorer.
    2. Press the CTRL button on the key board AND then RIGHT CLICK h your mouse
    3. Click on “Open in terminal.”
    4. Then cut and paste the following command:

    (Now the files should be listed in the “file_list.txt” file.)

    Watch this video for further instructions:

    Outdated Checklists and Special Notes Templates – Immediate Demerit to be applied

    • Some are using outdated checklists / special notes templates – this prevents the latest process being applied uniformly across all take offs. This has happened before more than once. If this happens, and you’re caught, this will result in an immediate demerit, unless you can explain otherwise.

    Folder Locations

    Please do not dump your reports in random locations. This makes it very difficult for clients to find especially if there are addendums, which means they MAY be using incorrect reports – which is unforgivable. If I catch you you will lose your entire bonus. (2025-10-31)

    If there is no profile information – PICK a random profile! (2025-02-18)

    Take for example the 537 Malvern Road MTO. Let us read from the special notes section:

    Structural drawings indicate steel columns (SC1,SC2 & SC3) in structural plan, but there is no member profile nomination provided for these columns in the member schedule. Therefore, those steel columns were not included in this takeoff report. Please refer below snap showing yellow highlighted columns.  In addition we have attached the highlighted markup for clarity

    And then the following image is attached:

    This is bad policy. Why? Because the client might not read the special notes and might mis-quote steel. it is better to add in an item with a nominated profile than to omit it entirely – in this case, at least the client will be ok if he quotes. If I see this happen again, you may endanger your bonus for a particular job.

    Make items perfectly visible (2026-02-18)

    This was for 26 Railway Parade, Hornsby. Almost all the items are not included, except the last one. But it is not highlighted in any particular way. Are you guys trying to confuse your clients? Highlight critical items to ensure it isn’t lost.

    Here is another example:

    This is 156 square meters of checker plate – which is not cheap. If you leave it like this, the client might miss – so consider highlighting where relevant.

    Isolated Material List Reports must have a separate IFC with them

    (again on the 537 Malvern Road MTO).

    When you have reports that segregate steel, you should also have the IFCs generated for each one of those reports. For example, if there is a PV platform, a canopy, a pergola, and roof steel, you should have separate IFC models for each one, as the case may be. This is so that people can recognise which steam corresponds to which items. Not doing so confuses myself, the client and wastes a lot of time.

    Special Client

    One of our clients wants their MTOs in a very special type of formatting. To that end, I have created an Apps script so we can transform our Tekla Members to be client with our client’s workflow:

    https://script.google.com/a/macros/tek1.com.au/s/AKfycbwh7F6kjwSvrkbk0rOBYlaIsEjWBEQEwiMndSYKhFw13ddlQeeGAPBOroitsGV2mrSWug/exec

    We will also need to create a schedule of Member Marks which map to our client’s Steel Codes.

    Backing Software:

    • https://github.com/benkoshy/mto_uploads – Private repository to transparently manage drawings and versioning via Google Drive API and Google workspace
    • Google App Scripts – to manage mapping from Tekla to our client specific take off codes. Link and instructions will be posted here.

    Answers to RFIs need to be proven with markups

    e.g. see Q18810 – PEGS Junior Boys Campus Stage 1 by Hari.

    This is the question by the client / builder:

    Include:

    • Window Shround Secondary Steel
      • Refer elevations BE3 through to BE5 on ST-300-02
    • Structural Steel Member shown in blue on Concrete Outline Plans
      • These are shown on structural documentation throughout
    • Structural Steel Lintels
      • These are shown on structural documentation throughout
    • Structural Steel to Makers Façade
      • Refer elevations BE3 through to BE5 on ST-300-02
    • Structural Steel to GRC Metal Cladding
      • Refer elevations BE3 through to BE5 on ST-300-02
    • Secondary Steel to Makers Entrance Eaves Gutter
      • This is shown on ST101-1
    • Structural Steel Framing concealed within ceiling cavity

    And here is the response:

    Inclusion:

    1. Window Shroud Secondary Steel.
    2. Structural steel lintels.
    3. Structural steel to makers facade.
    4. Structural steel to GRC metal cladding.
    5. Secondary steel to makers entrance eaves gutter.
    6. Structural steel framing concealed within ceiling cavity.
    7. Structural steel framing of planter storage(WT-03).

    Exclusion:

    1. Steel angle for perforated balustrade including steel plate and steel verticals
    2. Steel plate to support door frame
    • Terrible. Why? (a) Poor English: First of all the grammar is not clear. What do you mean: “Inclusion”? Does this mean you have included the steel or not? (b) Why Excluded? Secondly the exclusions: any reason why this is excluded? The client is paying you for doing the work, so you need a very good reason to exclude it, or there must be a measure, or a proxy by which you should enable the client to quote. (c) No proof: Generally speaking, if someone asks you a question, it is not enough to give the answer. You must provide your reasons / proof as well. In this case, if a client asks if you have accounted for PF1 profiles, what will constitute is the isometric view with the mark numbers. That is enough.

    Organise Folders – Don’t be a slob

    Architectural Finishes

    Please say yes / no if arch finishes are required. IF clients progress in the tendering stages, then they will almost certainly request an architectural review of the paint finishes. This might be an additional $6000 / tonne extra cost.

    How to fill out a checklist

    WARNING: How to fill a checklist. If people are filling the checklist first, and then doing the work later – if you forget or miss, that is a huge cost to me. You will incur punitive demerits from now on (i.e. not only will I remove this MTO bonus, but I might take away 2-3 more). Please take care.

    Paint Finishes

    For certain projects, it is necessary to give a thorough audit of the architectural finishes. Once you have done that, you need to communicate all the results to our clients via an Excel Spreadsheet. Secondly, reviewing the architectural finishes take time / complexity. Therefore, we need to submit a fee proposal to our client before do the work. In addition, we need approvals.

    Here is a sample file: Paint Finishes Sample here

    Cell References

    If functions

    Search Function

    iferror function

    Transpose Function

    How to put all of the above together

    =IF( IFERROR(SEARCH( L$5, $E6 ), 0), $K6, 0)

    • Where: L$5 is the paint finish (the search term input)
    • Where $E6 is the finish column (aggregated)
    • Where $K6 – is the tonnage you want to capture.
    • Please make sure that you don’t have two finishes which are encompass each other. e.g. with “PT1″ and PT11” the PT1 can be found and captured within a PT11! So your results will be incorrect.

    Renaming Files

    Clients find it annoying to open Excel if the file names are the same. Make it easy for your client my renaming the files so they are unique across the entire project where you have many different report sets – e.g. Building A, Building B etc.

    Downlaod Power Toys from here: https://github.com/microsoft/powertoys

    Please find above the settings required to rename a file.

    Executive Summary

    If your reports has many sections and sub-sections, you need to provide an “EXECUTIVE SUMMARY” to make it easy for your client to collate the tonnages and to quote the job. Make sure you add it to the “OVERALL TONNAGE” file.

    Building A: x tonnes

    Building B: y tonnes

    Building C: z tonnes etc.

  • Internal Processes

    Please find below the processes we expect all staff to follow:

    • Document all instructions in writing.
      • Why? Clients may call on the telephone. Communication may be confused. People say the wrong lengths, the wrong drawing numbers, and they might be working of the wrong revisions, and people hear the wrong things. If you receive instructions via the phone: put it in writing with any applicable mark ups to make sure that everyone is on the same page. Later on, if there is some miscommunication, it becomes a “he said – she said” blame game. We want to solve our clients problems not add to them.
      • Insist that communication is sent to the right people. If important communication is sent to the wrong person: perhaps a mark up or an RFI etc. then there is a chance that it could be missed.
    • Do not issue IFC drawings without IFA approvals.
      • Why? Clients will scream that they don’t care about approvals: but approvals are very important from a safety point of view. Be firm and clear: no IFC without IFA approvals. If a client wants to take a risk and build off an IFA drawing that that will be their prerogative. We do not want to risk someone’s safety in order to expedite a construction schedule.
    • Clear all outstanding RFIs before issuing drawings:
      • Why? If you don’t have the answers to the questions you need: then you can’t draw something on assumptions. What if those assumptions are not correct? Seek the answers you need before issues drawings.
    • DO NOT RUSH a job. Do it properly rather than do a rushed, or half-complete job.
      • Why? Because you will be likely to make mistakes and cost everyone even more down the line. If a client wants a ferrule moved on a mark up immediately, when there are 10 other items that need to be moved and verified, tell the client to wait. Because if those drawings are sent through, then you’ll need to send them again with those secondary revisions, and that will likely confuse people and cause huge problems down the line. Finish the job, do it properly and move on. Don’t be pressured to deliver a shoddy work due to time pressures. Yes we are all pressured by time, but there’s no point doing it badly and then costing everyone going forward.

  • ESTIMATION MODELS AND TAKE OFF

    Tek1 has developed plug ins with IntelliCAD based systems to create take off models from PDF drawings. The PDF drawings are brought into the intellicad based cad systems. Columns and Beams are modeled over the PDF drawings.

    This method is significantly faster than undertaking blue beam takeoffs.  The accuracy of the take off is much better than what is possible with blue beam or any other PDF based take off system.

    The inellicad model is then exported into Tekla using an in house plug in. Material Lists, and GAL lists can be taken out of the Tekla Model.

    An IFC model is exported from Tekla. Along with a 3d model, this type of take off provides great value of the estimator.

    Pricing is very competitive since we are using our in house offshore team. The take off team is now of a significant in size. Because IntelliCAD software is cheap, and given our in-house plug in, we are able to provide, fast and very cost effective services in take off modeling.

    Fittings and bolts are not normally included in the take off.

    Here is an example of the Essendon hanger we completed today (29/1/2020).

  • .dwg based Take off with custom Plug ins

    Tek1 has developed .dwg based plugins which talk to Tekla to carry out take-off efficiently

    Take off is completed in .dwg based Cad systems very similar to modeling in Tekla. For BIM model the model is converted to Tekla

    Reports can be taken either from .dwg system or Tekla. Right now reports are being taken out of Tekla. Our next effort is to develop a plugin which will convert the .dwg model into an IFC model.

    If anyone is able to help us in this developing the plug int convert .dwg based model to an IFC model we will be very interested.

    Here is a sample file.

    Tek1 has developed ACTCAD based take off tools of easy estimation. Members are modelled in ACTCAD and converted to Tekla with single click with an API call. In some cases we are now able to create IFC straight from .dwg models.

    Deliverables include IFC model, and reports. Reports as below.
