Who do I send a Pay Application to?2018-01-23T16:49:59+00:00

All pay applications need to be submitted to projectmanagement@sigmacontracting.com and need to be to our office by the 20th of each month and the percentage of completion needs to be projected to the end of the month, unless a project has other specific requirements.

How do I fill out the Pay Application?2018-01-23T16:51:44+00:00

The form should be self-explanatory but you will need to include the following information:

  3. PERIOD ENDING DATE – Usually this is the end of the month
  4. JOB NUMBER – The Sigma job number
  5. PAYMENT APPLICATION NUMBER – This is your number (example, your second draw request is 2)
  6. ORIGINAL CONTRACT SUM – Your original contract value
  7. % COMPLETE – This is the total percent of work you have completed to date
  8. WORK COMPLETED – Multiply the contract value by the percent complete
  9. APPROVED SIGMA C/O’S – List all approved change orders, if any, and calculate the percent complete of each change order
  10. REVISED CONTRACT AMOUT – Total of original contract plus approved change orders
  11. PENDING CHANGE ORDERS– List any change orders that you have issued to Sigma but have not received an approved written Sigma change order
    1. This helps us make sure we do not miss any of your pending change orders. They may or may not be paid with that application but they could be moved to an approved condition and paid if the work is completed
  13. LESS PREVIOUS PAYMENTS – Subtract what has previously been requested to date
  14. TOTAL DUE THIS APPLICATION – Subtract the retention and the previously requested payments from the Total Completed to Date

What is my deadline for submitting Pay Applications?2018-01-23T17:00:05+00:00

The deadline for submitting a Pay Application is the 20th of each month (unless noted otherwise in your contract). Pay Applications must be received by the 20th of the month to be processed for that pay period.
a. In the event your payment application is received after the 20th deadline, your invoice will be processed the following month

When are Change Orders considered approved?2018-01-23T17:23:47+00:00

Internally, we do everything possible to expedite the process and obtain approvals on Change Orders. If there is a change order that is a back charge from one trade to another or if there is something that was omitted from the subcontract and is a legitimate change order, those will be processed very quickly as they do not require the project’s Ownership approval.

If a change order is being processed through the project’s Ownership then we all must wait until it goes through the formal acceptance of Sigma receiving a signed change order then Sigma issuing the subsequent subcontractor change orders.

Once a formal change order has been executed by Sigma and your firm you can then include it in the Pay Application process. Up until then it is considered pending.

If a subcontractor Change Order is not approved, do I put it on the Pay Application?2018-01-23T17:32:08+00:00

Yes! These should be included in the “Pending Change Order” section of the Pay Application. This will help to ensure that Project Management is fully aware of any pending change orders that might be out there.

How long does it take to get paid?2018-01-23T18:28:12+00:00

We pay within seven (7) days after receipt of payment from the Owner, per the Arizona Prompt Payment Act.

Most Owners strive to pay us in a timely manner so we in turn can release funding to the trades but some Owners don’t always make this happen for a variety of reasons. As such we have partnered with Contractor’s Capital Solutions (CCS) to provide an early payment option for our subcontractors. If you would like to investigate this in greater detail please go to the link listed below to establish an account with them. If this is a service of interest and you meet their requirements and establish an account you could have payments within 24 hours of a submitted and approved (by Sigma) pay application.
