Absolute minimum Anchor Spacing
Please note that the spacing and edge distances given in the ferrule tables is for design purposes only and not a minimum for actual installation. That is the dimensions given are for each insert to achieve 100% capacity. They can be placed closer. It just means their combined capacity will be reduced. The same is for drilled and epoxied bars.

Subject Line it Emails
When writing subject line in emails, DO NOT JOIN WORDS WITH “_”.
Example Q10231_MACORNA ST SUP BRIDGE.
In the above subject line words are connected by underscore. On mail search by subject line, a search for Q10231 will not bring up the mail
A better approch will be do not use underscore separate by space

When projects are delayed we need to invoice
These are our terms
VariationsVariations affect our cash flow adversely. In the event of any variations, we may need payment prorata for work already completed, before we take up variations — if they cause major delays in the submission of approval drgs. Variations are charged at the above mentioned rate. You will be notified of variations as and when they appear and are applicable. If you do not agree to the variations we are claiming,please inform us within 72 hours of us sending you the notice. If we do not receive a notification from you refusing our claim then this we will presume you to accept the variation, and we will continue to implement the applicable changes required in the drawing and bill it accordingly. Variations will be billed every week and is payable within 7 days. If payments are not made on time, we reserve the right to stop work without being liable for any consequential losses which may arise as a result

Maximum Cleat Heights for Purlins and Girts
There are recommended maximum heights for purlins and Girts. If you want more heights the options are increase cleat thickness ore change cleat profile to may be equal angle profile.
Expert steel detailers will know what to do and will use the appropriate thickness and profile
If you are using 8 mm plate cleat, you can go upto 150 mm max
Beyond that use an EA cleat
75×6 EA is good.
Increasing plate thickness may not be a good option because of PB30 bolt where the bolt length is only 30 mm.

Australian Standards – Available for Staff at Tek1 on the firm’s Google Drive
All staff should have access to the relevant Standards.
You should be familiar with them, and master them – otherwise you will embarrass yourself, and the firm, if you claim knowledge but demonstrate ignorance. The latter is especially costly to clients, and detrimental to your name and reputation (as well as the firm’s) – you certainly will not be getting repeat work if you prove ignorance.
Please access them at the firm’s google drive location here.

Adding details without approval which affects other trades
This memo clarifies the process for handling drawing approvals and issuance to ensure project coordination and minimize potential errors.
Drawing Approval Reviews:
When receiving approved drawings, carefully review them for any markups that may significantly impact other trades or existing structural elements (e.g., slabs, foundations, anchor bolts).
Example: If an approved drawing introduces a slab pocket where none existed in the original design, ensure the following steps are taken:
- Verify Slab Status: Issue an RFI (Request for Information) to determine the current status of the slab construction.
- Coordinate with Relevant Parties: Communicate the design change to the construction crew responsible for pouring the slab.
- Provide Updated Drawings: Issue revised slab drawings reflecting the pocket addition.
Failure to take these steps can lead to costly rework and project delays.
Issuing Drawings Before Approval:
Construction drawings should only be issued prior to approval if specifically requested by the client. In such cases, the drawings must be clearly marked and include a disclaimer.
Scenario 1: Client Does Not Require “For Construction” Marking
- Issue a full set of drawings marked “Issued for Approval” (IFA).
- Include a disclaimer stating that the drawings are not yet approved and their use is at the client’s own risk.
Scenario 2: Client Requires “For Construction” Marking
- Issue the drawings marked “For Construction.”
- Include a disclaimer stating that the client was informed of the drawings’ unapproved status but requested them for construction at their own risk.
- Obtain a written statement from the client acknowledging their request and acceptance of responsibility.
This process ensures clear communication and accountability in the drawing issuance process, mitigating potential risks associated with using unapproved drawings.
