PROJECT : SUPPLEMENTAL ARCHAEOLOGICAL PHASE IINVESTIGATION FOR THE II TH
STREET BRIDGE PROJECT, CITY OF WATERLOO, IOWA
LABOR TOTAL $ 5,765
EXPENSES TOTAL $ 1,126
GRAND TOTAL $ 6,891 [costs may be shifted within budget to reflect actual labor & receipts.]
Scope of Work - SUPPLEMENTAL Archaeological Phase I Investigation. This investigation will examine to
the Phase I level a new area supplemental to the original 11th Street Bridge APE that will encompass a proposed
temporary driveway for the Midwest Pattern Co where it extends outside of the previously -surveyed APE (see
attached maps). It is anticipated that the fieldwork will take two days and will involve intensive subsurface testing
(shovel/auger tests to a maximum of 1 meter below the current ground surface) wherever possible and where
needed to address the presence/absence of archaeological sites. The testing interval is proposal for 10 meters since
it is anticipated that at least one historic house site will be encountered. There is also potential for a precontact
component in this area as well. The state guidelines for Phase I intensive survey as approved and revised by the
AIA in October 2021 will be followed for both the fieldwork and the report stages of the project.
Schedule - the fieldwork will commence as soon as possible after a notice to proceed but dependent on the
ground being thawed in order to meet the AIA guidelines for adequate field conditions. A summary report can be
submitted within 20 business days or less following the end of the fieldwork.
Note - the above proposal is considered a not -to -exceed cost estimated.
