DVBE Requirements
The Department of Transportation has implemented new DVBE goal setting procedures on its non-federal aid construction contracts over $250,000.
Effective March 21, 2011, state funded contracts advertised will have the following DVBE goals:

  • $1 million and under 5% DVBE goals.
  • $1 million and $5 million 3% DVBE goals.
  • Over $5 million No goals. DVBE incentive provisions apply.
Bidders are reminded that good faith efforts do not apply to these contracts.
Bidders are cautioned to use certified DVBE firms performing commercially-useful functions on the contract in order to receive credit towards the DVBE goals or incentives.
Each contract advertisement, Notice to Bidders and Special Provisions contain the DVBE requirements.
If you have any questions about the DVBE goals, please submit a bidder's inquiry.

Attention contractors:

If you'd like to pull back your submitted bid to make corrections, make sure you fill out the latest signature card and fax it in to the bidder's exchange. We also have a new release of bid documents form to keep with your bid runner in the event that you need to revise a bid. Both files are available on our Contractor Info Table, under the Bid Opening column.

File Format Information

.doc (.DOC) Files
Many Office Engineer text files use the "hidden text" feature of Microsoft Word. Therefore, it is recommended that only MS-Word be used to ensure full file compatibility. MS-Word files are readable with MS-Word 97 or greater for Windows, or MS-Word 98 or greater for Macintosh. Due to the usage of unique MS-Word features in some files, they must be distributed in the .doc
(Word 97/98) file format.
Office Engineer is unable to provide these files in other text formats.

.pdf (.PDF) Files
These are files that can be view using the free Adobe Acrobat Reader available
at Adobe's web site. Acrobat Reader is available for many platforms including:
Macintosh and Windows.

.tif, .TIF, .tiff, .TIFF Files
These are graphic files that can be read with any application capable of reading "tiff" files, such as:

  • Macintosh workstations can use iPhoto or other options to view and print images
  • Windows workstations can open TIFF files using software built into the Windows operating system, or one of many third-party applications
  • TIF files can be printed on full-size (24 x 36 inch) plan sheets at local shops specializing in document imaging, drafting supply, blueprinting, or plotting. Check your local listings for vendors in your area.
