SUBJECT: Request to Amend Contract Amount for Fire Tower Construction 
 
BACKGROUND 
In the original bid documents for the Fire Tower Construction, we included lump sum costs for excavation, 
fill material, and electrical wiring.  However, we did not include a general contingency line item in the 
contract as we do with most projects which are handled under one umbrella contract as opposed to this 
project which has been developed in phases.  Similarly, to other projects there are some additional items 
that need to be addressed now that we have begun construction of th e foundation and received the 
tower.  Because of this being a prefabricated building, we anticipate less changes moving forward than 
with a traditional construction project.  However, we would like to request a contingency allotment to 
cover the current items we need to address and any future items which may arise during this phase of the 
project. 
 
Contingency budgets generally range from 10% to 15% of the project cost.  In this case we are requesting 
a total of $4 0,000, which is approximately 12.5%  of the budget .  We currently have received a change 
order which we requested to upgrade the electrical service for the tower.  This change order is for 
$17,057.36.  The original scope only provided electrical for the items being shipped with the tower 
package and after discussion with the manufacture r and other departments we believe the addition of 
lighting would enhance safety and security.  This change order would add these services, as well as provide 
extra capacity should we decide something needs to be added in the future.   We also had to utiliz e the 
lump sum clause from the bid package to bring in fill material for the foundation.  The cost for this work 
is approximately $980.  With both items added to the project, roughly 45% of the contingency will already 
be allocated. 
   
ACTION ITEM 
Approve an amendment to the Fire Tower Installation contract with Wilson Construction to include a total 
of $40,000 of contingency funding.
