DBE/MBE/WBE/SBE/TGB Certified: HI, IA, MN, ND, SD, WI
Terms and Conditions of Proposal 1. Proposal Inclusions
This proposal incorporates, by reference, all contract documents for the referenced project. The scope of this quotation
only covers material. Erection and/or field installation is not included.
2. Quantities
Quantities illustrated within the quotation are purely for the Buyer’s guidance. The quantities are not guaranteed to be the
amount required by the contract documents.
3. Assembly:
Unless explicitly stated within the notes section of the proposal, the scope of the proposal does not include assembly of
materials supplied.
4. Field Dimensions:
Required field dimensions shall be furnished by the Buyer. The scope of the proposal does not include field dimension-
ing. If Buyer fails to provide required dimensions, we will fabricate according to the best information available to us.
Failure to provide field dimensions in a timely manner may result in additional material lead time. We will not be respon-
sible for misfits due to discrepancies between design plans and field conditions.
5. Fabrication Lead Time:
Material lead time may be 8-12 weeks after drawing approval. Additional coordination with us may be necessary in order
to meet projected project timelines.
6. Delivery:
Aura Fabricators, Inc. will make every attempt to deliver at the requested time. However, we will not accept any charges
for delays either for lost production time or for any liquidated damages that the owner may assess against the Buyer.
7. Limitations of Liabilities
Under no circumstances will Aura Fabricators, Inc. be liable of any indirect, incidental, consequential or punitive dam-
ages as a limitation is also extended to any third parties who may be involved. The scope of our responsibility only ex-
tends to rectify any errors that we have made in our own work, which would be completed as quickly as possible. The
Buyer will be given written approval to complete such amendments or to replace material that does not meet contract doc-
ument requirements.
8. Back Charges:
We must give written consent before we will honor any claims for labor and/or materials supplied by Buyer in connection
with our work. Therefore, we must be advised before any such expenses occur.
9. Warranties:
Aura Fabricators, Inc.’s only responsibility is to ensure that all materials included within this proposal shall conform to
the contract documents for the referenced project. Since design plans are prepared by others, we make no warranties for
fitness for a particular purpose.
10. Payment:
Cash terms are net 30 days. We do not accept retainages and we will not extend payment beyond 30 days due to non-
receipt of monies from the Owner. A charge at an interest rate of 1.5% per month shall be applied on accounts past due.
11. Proposal Expiration
This proposal is valid for acceptance within 14 days. Subsequently, acceptance is subject to review. Acceptance may be
made subject to award of contract to Buyer.

Pam Please see the attached documentation. Once the existing structural steel girders were removed and placed at grade for cleaning, a review of their existing conditions was performed by Shoemaker Haaland. Based on that review, they have recommended some modifications to the existing girders to account for some of the deterioration that had occurred at the bracing connection points. I asked PCI to provide a break down of the Welding Hours to support the pricing. That is in italics below. Hawkeye Weld & Repair has the following labor breakdown: Onsite Field Welding & Fit‐Up Labor/Equipment $4,600.00 40 hours @ $115.00/HR Mobilization/Travel Time $500.00 Thanks JacobA.Hahn,P.E.,LEEDAPAssistantCityEngineer | Engineering Department1225 6th Avenue – Suite 200 | Marion, Iowa 52302 p 319-743-6340 | c 319-329-5173 | f 319-373-4260 [email protected]
