CHANGE ORDER
Order No.: 003
Date: June 30, 2025
Agreement Date: November 25, 2024
NAME OF PROJECT: East Nottingham Park Improvements
OWNER: Town of Avon, Colorado
CONTRACTOR: __Baker Builders, LLC dba Baker Constructors
The following changes are hereby made to the CONTRACT DOCUMENTS :
Justification: Changes detailed herein capture changes to the Utility Plan to route the Sanitary
Sewer Main, additional tree demolition approved by Avon, relocation of one of the primary electric
vaults, and updates to the modular building delivery schedule. See the spreadsheet in Attachment
A for a summary of the revised plan quantities, resulting in a total contract adjustment of
$48,663.62. None of adjustments herein result in a change to the contract time. See Attachment
B for the revised drawing sheet and markups.
DEMO & SITEWORK ($7,300.90): This item includes the additional tree demolition detailed in
markup of Sheet C-02 in Attachment B. Removal of 10 additional trees was added to the existing
11 trees to be demolished as shown on Sheet C-02. Per contract demolition Line Item 7 Trees, the
cost of each tree demos is $730.09, adding $7,300.90 to the contract. This item also includes
adjustment to the demo plan for changes for sanitary sewer (SS) service line relocation See
Revised Sheets C-02 in Attachment B. The relocated SS line reduces the amount of pavement
cut and removal (-39 LF), basecourse place (-1.6 TN), and asphalt re-laid (-1 TN). However, the
deep excavation is anticipated to impact additional asphalt, and was therefore these items were not
adjusted.
UTILITIES ($41,630.64): Avon provided the paint striping and will provide ADA thermoplastic
markings for the parking along Lake Street, crediting the project $1,232.56 as detail below:
- Line Item 37: Striping (4” White): 236 LF parking stall lines striping (11 at 21.5 LF) plus
the 76 LF ADA cross hatching (8 stripes at 9.5 ft long), totaling 312 LF at $2.38 per LF
crediting the project $742.56.
- Line Item 38: Thermoplastic Pavement Marking: Avon will provide two 40 x 36-inch ADA
thermoplastics totaling 20 SF. At 24.50 per SF, this credits the project $490.
Additionally, revised Sheet C-04 in Attachment B details needed relocation and
extension/replacement of the SS line. The changes increased the length of 4” SS line by +68 LF
and requires deep excavation and booting at the existing penetration into the manhole. As detailed
in marked up Baker PCO 001v4, Attachment C, change order cost for the SS Line (Baker PCO
001) increase the contract by $42,864 for the following additions:
- Line Item 48: Extension of the 4” SDR35 SS line by 68 LF at $248.22/LF, adding $16,879
CO-3
Form Approved by Town Attorney – 05/15/2024
- Line Item 48a: Internal Manhole Drop: including ~16 LF of 4” PVC Pipe and a wye and
45 deg bends to redirect flow into the manhole invert flowline, increase of $3,972.
- Deep excavation adjacent to the manhole increasing the cost of work by $16,480.
- Utility potholing, additional time in confined space, compaction testing, and surveying ;
adding $4,484.
- A 5% margin and overhead of $1,893 at detailed. However, that cost built into the unit
price on contract line items. Therefore, $844 and $199 of Margin & Overhead are
disallowed from the contract increase for the 4” sewer line extension Line Item 48, leaving
an increase of $1,049.
It is acknowledged that a Union Pacific Railroad Permit needs to be located to add a barrel section
to the manhole work given its existing encroachment onto the railroad. Therefore, that work is
unlikely to take place, and the cost is not addressed herein. Therefore, the total contract increase
detailed herein is $41,630.64.
OVERHEAD ELECTRIC BURY ($0): CO1 detailed that the length of Line Item 92 Electric
Primary Trenching w/ Conduit between the railroad casing and the surface location of intercepting
the conduit had not been resolved.
- On the Northside of the Railroad Casing: It was determined that the Vault V3 installation location
would be over the Heat Recovery Piping, which may be problematic in the future. Therefore, Vault
V3 was relocated further east to eliminate this concern as shown in Attachment B.
- On the Southside of the Railroad: The primary electric line crossed the heat recovery pipes and
conduit bank of power and data lines that are encased in red concrete at a shallow depth. With
Holy Cross Energy, it was determined that to best solution was to run the primary electric conduits
shallow over the top of the Heat Recovery lines and encase them in red concrete. That extra work
was completed and determined to be similar in value to the ~20LF of Line Item 92 electrical
conduit work that did not need to be run between the railroad casing and surface vault locations.
Therefore, these adjustments are a $0 and 0 day change to the contract and resolve the outstanding
items around Line Item 92.
Change to CONTRACT PRICE: $ $48,932.34
Original CONTRACT PRICE: $ 3,940,836.00
Current CONTRACT PRICE adjusted by previous CHANGE ORDER $ 3,890,689.25
The CONTRACT PRICE due to this CHANGE ORDER will be increased by $48,932.34.
The new CONTRACT PRICE including this CHANGE ORDER will be $ 3,939,621.59.
Change to CONTRACT TIME:
The CONTRACT TIME will be (increased)(decreased) by 0 calendar days.
The date for completion of all work will be May 20, 2026.

Ok, well thank you for sorting that. I spoke with Operations, and they mentioned that there is a comcast
box and a few irrigation boxes that may need moved or capped. Otherwise, this relocation is acceptable
to us.
I will work with Jeff Vroom on the easement update.

They did have to spend an extra day potholing all the different utility crossings coming out of the railroad casing,
but there will not be a cost impact other than any easement filings for yourself.
Speaking of easements, does ERWSD have an easement for the manhole that would allow us to work in that area?
Thanks,

Clayton from RPM stated that he has walked the location of the new vault with you and we are moving the vault so
that it does not get installed over the top of the existing hot water recovery line. Are you OK with the revised
location per the attached drawing?
