Structural Steel Detailing / Workshop Drawings

Structural steelwork detailing (Workshop Drawings) is prepared on a "per tonne of steelwork detailed" basis.

Provision of PDF Files Only

The current rate for preparing the detail drawings where only PDF files are provided varies between $420 and $1,180 per tonne calculated using a density of 7.85 tonnes per cubic metre.

In addition to this, there is the 3D structural model from which the detail drawings are prepared. This is charged on an hourly rate basis. The current rate is $84 per hour (ex. GST).

Provision of DWG and/or DXF Files

If DWG and/or DXF files are required, this must be clearly stated before anything is agreed and before any work has commenced. The client must provide all symbols libraries, setup templates, layer templates, pen colours:pen width mapping, drawing sheet borders, font files, linetype files, etc. Only information that is provided will be used in preparing the drawings. 

Also, the client accepts full responsibility in the interpretation of the drawings as symbols and standards used may not conform to Australian Standards

Because of now having to work with unfamiliar settings and standards, there is a surcharge applied to the preparation of the drawings. 

Where DWG and/or DXF files are required, the current rate for preparing the detail drawings varies between  $632 and $1772, per tonne calculated using a density of 7.85 tonnes per cubic metre.

In addition to this, there is the 3D structural model from which the detail drawings are prepared. This is charged on an hourly rate basis. The current rate is $128 per hour (ex. GST).

Detailing is not commenced until the complete 3D structural model is completed and accepted. Once the 3D structural model is completed and accepted, any changes to the model will be an extra.

Quotation

Before any quotation can be provided for workshop drawings, the following information MUST be provided.

Remember, all this information must be available for the Structural Engineer to be able to certify the structure. This can be summarised by the 4 C's - Clear, Concise, Complete, Correct.

Extras

Extras will be charged where the structure is altered (i.e. members removed, or members added, members changed, structure cannot be resolved). This will be charged at the standard hourly rate to cover the redrawing, plus an additional amount for the new tonnage detailed or amended.

Site visits are charged at the standard hourly rate plus kilometerage, and it is conditional that free on-site parking is made available for a vehicle with a height clearance requirement of 1.96 m. All tolls and other charges are to be reimbursed.

Payment Schedule

For these payment milestones, if payment is not made by Direct Debit, then a cheque must be provided and cleared by the bank before any commencement of work for the initial pre-payment, issuing the drawings FOR APPROVAL, or issuing the drawings FOR CONSTRUCTION.

If the cheque is dishonoured, the dishonour fee, plus any additional costs incurred by WAI Engineering will also be charged, and those additional charges must be paid before the particular milestone can be passed. Authorities will be notified where it is believed that deception is involved (eg: a cheque is raised for a particular milestone payment when the issuer knows there are insufficient funds to cover the cheque).

Drawings will be submitted for approval as PDF files, however they will be watermarked and clearly marked as FOR APPROVAL ONLY and NOT FOR CONSTRUCTION. Use of such drawings is not advised as they may not contain all changes for the structure to be manufactured correctly. Only drawings clearly marked as FOR CONSTRUCTION are to be used to manufacture or order any items.

All invoices for works provided to the Building & Construction industry are issued under the Building & Construction Industry Security of Payments Act - 1999.

Delivery of Drawings, Ownership & Permission to Use Drawings

Other than incidental drawings covering items that need clarification as a result of detailing, no drawings will be provided other than at the milestones set out above. All drawings remain the property of WAI Engineering until such time as ALL amounts invoiced are paid and cleared by the bank. Permission to use the drawings is only given once ALL amounts invoiced are paid and cleared by the bank. This permission will be provided in a formal document and will be for the specified project only. Use outside these conditions would be considered a breach of intellectual property rights and will be pursued.

Deliverables will be as set out by the Australian Institute of Steel Detailers.
