SUBJECT:  Construction Manager at Risk – Change Order  
 
Dear Mr. Riter, 
 
B&F Contracting, Inc. respectfully submits, for your review, our Proposal for additional CIPP lining of 48-
inch & 27-inch pipe on the Price Road Frontage Road Sewer Rehabilitation. B&F proposes to complete this 
work on directly after the contract work is complete utilizing the same equipment to convey flow an 
addition 750 LF downstream of the current discharge to complete the 48-inch pipelining from Frye Road 
to the Price Diversion Structure. To accommodate this, work the bypass will need to be extended and the 
Frye Road Bypass run time will be extended beyond the original duration in the GMP-001. Also included 
in this proposal is pricing to complete CIPP lining of the 27-inch line at Frye Road. The line was CCTV 
inspected and has buried manhole under ADOT concrete pavement that would need rehabilitated 80 lf 
off the price 42” main. This proposal would CIPP line from the new upstream manhole through this buried 
manhole to the new polymer downstream manhole and completely cut off corrosive gases to the manhole 
on the ADOT property and eliminate the need to abandon or rehabilitate the manhole. The price includes 
all labor, equipment, material, and services to complete this additional work. See the attached schedule 
of values for reference.

Assumptions specific to this project: 
- 
Insituform will continue these installations with minimum gap (approximately a month) from finishing the 
current Chandler Over the Hole installations, so we can keep most of the OTH equipment in Tempe 
- 
Designs are based on following MH depths measured: 21 feet at Frye Rd, 15 feet at Fairview Rd and 10 feet 
at MH with bend 
- 
We will install two OTH shots from Fairview St manhole, one to Frye Rd and other to the Structure 
 
All other assumptions, inclusions and exclusions remain same per the original contract. Please do not hesitate to 
contact me with any further questions. 
 
Very truly yours,
