Change Order No. 4
8006 — Amount of removals is approximately double the original bid quantity. The original bid price for removals was $20,000.
8007 — The original price for installation of the causeway was $27,500. The lump sum price provided by the contractor appears
reasonable based on the original price, and the work required to move the causeway to allow the repair work to be completed.
8008 — The contractor will be required to provide substantial additional oversight of subcontractor completing the work, as well as
considerable estimating time for this additional work.
8009 — The structural concrete price for this change order work appears reasonable in comparison to the original bid price of
$1,085.
8010 — The reinforcing steel price for this change order work appears reasonable in comparison to the original bid price of $1.60.
8011— Prime contractor for this job requested quotes from two subs for this work. The lump sum mobilization price appears
reasonable for bringing in specialty equipment to the job site.
8012 — Prime contractor for this job requested quotes from two subs for this work. The per LF price appears to be within reason for
the work required, particularly considering the short pile lengths.
55 additional working days will be added to contract for this work. This change order significantly changes the scope of the work. In
addition, the site conditions (building in the Cedar River), have not allowed a typical construction sequencing for the original scope of
work, and have necessitated the addition of additional working days.
