Retainage

Section 810.90 Retainage
The Department shall retain up
to ten percent of its total share of a project as follows: for projects of
less than $25,000, no retainage shall be held; for projects of more than
$25,000 but less than $500,000, ten percent shall be retained; for projects of
$500,000 or greater, five percent shall be retained. The following are the two
instances when the State's retainage is released:
a) If the State is financing only part of the project, the
retainage shall be released to the recipient within ninety calendar days of
when the Department verifies that the State's share of the project has been
completed, and the remaining portion of the project is proceeding on schedule,
as evidenced by the Department's engineering inspection reports. (Engineering
inspections are required in accordance with the Department of Transportation
Act (49 USC 1654, as amended by the Local Rail Service Assistance Act of
1978)). If the remaining portion of the project is not on schedule, then the
State will hold the retainage until total project completion; and
b) If the State is financing the total project, the retainage
will be released to the recipient within ninety days after the Department's
engineer has approved total project completion. Total project completion is
determined by the Department's engineer and coincides with the completion of
all work or line items found within the project contract.
