ATTACHMENT “A” (Change Order Scope) 
Project Name: Vulture Mountain Recreation Area, Phases II & III 
Contract #: 240064-DBB 
Change Order #: 25 
Project #: TR225 
Reason: 
This Change Order Will: 
1) Extend Contract Time By 130 Calendar Days
2) Create Item 002.00991-25: Extended General Conditions
Description: 
Change Order No. 25 will extend the project’s General Conditions to cover the additional 
contract time required as shown within the Contractor’s April 23rd, 2026, construction schedule 
update. The Contractor’s baseline construction schedule originally showed a substantial 
completion date of July 24, 2026. The current anticipated project substantial completion date is 
December 1, 2026, resulting in a net difference of 130 calendar days. 
Moreover, this Change Order will increase the project’s General Conditions budget due to the 
time extension.  The expansion of the General Condition budget authorized via this Change 
Order will exclude the cost & schedule impacts that may result from the following unresolved 
project events: 
•
Additional electrical underground work resulting from the increased quantity of Project
Service Entrance Sections (SES) to be installed as recorded via Change Order No. 19.
•
The procurement and installation of a free chlorination boosting system (FCBS) at the
Water Storage Tank.
•
The procurement and installation of a 3-phase fire booster pump for the Well Site.
•
Any additional work derived from the establishment of interim and/or permanent
electrical and telecommunication utility services.
•
Any work that requires the Design Team and/or their Engineers to complete for TSG to
price and receive approval to release for procurement.
The construction schedule and financial considerations for these above-mentioned events could 
not be determined as of the date of this Change Order.  The Contractor will assess the project 
delivery impacts (time & cost) for each event, at a later date, and reserves the right to seek 
further compensation from the Project Owner should additional recompense be merited. 
The General Conditions Budget established for the project’s original contract duration of 580 
calendar days is $1,597,320.00.  This Change Order will expand the General Conditions Budget at 
the same daily accrual rate incurred during the original contract period. 
Docusign Envelope ID: B8C62597-9B9B-8619-82FE-59CCAE5A3150

Revised 2-26 
Therefore, the quotient of $1,597,320.00 divided by 580 calendar days is $2,754.00 per calendar 
day.  
Subsequently, the product of extending contract time by 130 calendar days multiplied by 
$2,754.00 per calendar day is $358,020.00.  After accounting for the authorized project 
adjustments for taxes, bonding, insurance, and contractor mark-up, the total Extended General 
Conditions tabulates to $440,773.08. 
Authorized Exclusions from the Extended General Conditions

Additional costs associated with the above-listed items will be addressed on a case-by-case basis 
in the event monies expended by the Contractor to satisfy the project’s General Conditions 
exceed those monies received from the Project Owner via these Lump Sum bid item(s). 
Additional Fees to Extend Building Permits 
Docusign Envelope ID: B8C62597-9B9B-8619-82FE-59CCAE5A3150

Revised 2-26 
The building permits acquired through the Arizona Department of Housing to furnish and install 
ten (10) project structures are set to expire in September 2026.  The Contractor is actively 
engaged in permit renewal to avoid the disruption of construction progress. The costs to extend 
all applicable permit(s) are excluded from this Extended General Conditions change order and 
will be reimbursed within a future contract revision. 
Renewal of Permit Builder’s Risk Insurance Policy 
The term for Builder’s Risk Insurance acquired for the original contract duration of Vulture 
Mountain Recreational Area project is set to expire in July 2026.  The Contractor is currently 
pursuing policy renewal, and the new insurance premium rates are not known at the time of this 
contract revision. 
Therefore, the Contractor and Project Owner have agreed to exclude these costs from Change 
Order No. 25 in favor of creating a forthcoming contract revision to compensate for the renewal 
of the project’s Builder’s Risk Insurance Policy.

Project Name: Vulture Mountain Recreation Area, Phases II & III 
 
Contract #: 240064-DBB 
Change Order #: 27  
Project #: TR225 
Reason: 
This Change Order is to: 
 
Create the following item: 
 
Item 002.00160-27 Chlorination System Modifications, Quantity 1 EA, Unit price is 
$266,944.60. 
   
 
Description: 
Due to the relocation of the well from its previous location adjacent to the storage tank 
to a new site approximately 1.3 miles away, and alteration to the way the water system 
operates, an additional chlorination system is required. The water is chlorinated as it is 
pumped from the well into the system. However, since water is also pumped to and 
held in the storage tank, an additional chlorinator is required to maintain required 
chlorine levels. 
 
The designer (EPS) worked with the tank manufacture (D&R Tanks) to select the 
appropriate chlorination systems and complete the required design revisions. 
 
This change order will compensate the contractor for the cost of all materials and labor 
associated with furnishing and installing the tank-mounted chlorinator in accordance 
with the approved revised design requirements.
