This letter will confirm your authorization for Architerra Design Group (ADG) to provide additional services beyond our original scope of work for the Vernon City Hall project.
Our services are generally described as adding additional scope of work and fee to the original construction document contract to include work not originally included based on the final agreed upon Conceptual Landscape Plans, Conceptual Graphics, desired elements and materials requested by the City, and Code Requirements.
This additional scope of work includes time to add additional areas originally outside of our limit of work such as the building frontage along Sante Fe Avenue.
This agreement includes time to break out the project cost estimates, construction documents, bidding assistance, and subconsultants work out into three separate phases, and ADG's coordination time with subconsultants and city staff.
Lastly, this agreement includes time allocated for the creation of conceptual 3D renderings to help visualize the potential appearance of the Plaza upon completion.
The additional scope of work and fee will be added to the originally approved contract amount, dated February 21st, 2023, and will be as listed below:
1. Added Additional Area and Three Phases to Landscape Scope Additional scope of work to include the new area along the southern building frontage and streetscape facing Santa Fe Avenue.
This fee covers the additional base sheet, construction, planting, and irrigation scope of work required for this newly added area. This fee and additional scope of work will also include time for separating out the project, cost estimates, and packages out into three separate phases based on City feedback and construction budgets. a. $9,300.00

2. Added Custom Detailing to Landscape Scope
Additional custom construction detailing covering custom elements within the plaza and time needed to design and detail these items.
The original contract provided an estimate without having a final design in place, and did not account for the different types of materials or custom design elements.
We calculated the additional scope of work needed for the additional details and subtracted out the original amount from the original contracted fee already accounted for.
a. $10,300.00
3. Added Structural Engineering and included 3 Phase Breakout Additional structural engineering for completion of analysis, design, and calculations of attachment of new custom sign to the parking garage wall, relocated City medallion to be altached to the parking garage wall, two ground level monument walls, custom steel & wood trellis overhead structures, up to four large flagpoles with anchoring foundations, and the custom post / bollard laser etched lighting standards with anchoring foundations.
This fee includes time for RFI responses and shop drawing & material review. This fee also accounts for separating the scope into three separate phases. See attached ISE Proposal.
$8,600.00
4. Added Required Water Quality Improvements Based on Final Design Additional civil engineering for Standard Urban Storm Water Mitigation Plan (SUSMP) & the related Best Management Practices (BMPs) to include the required calculations. studies, and related details.
This scope of work is not separated into three separate phases, as the report must be completed for the project in its entirety. See attached Madole Proposal. a. $9,350.00
5. Added Required Erosion Control and included 3 Phase Breakout Additional civil engineering to prepare an erosion control plan due to the increasea disturbance. It has been determined that less than an acre of disturbance will occur and therefore SWPPP will NOT be required, but the City will likely still want an Erosion Control Plan completed.
This includes additional time to separate the Erosion Control Plan into three separate phases. See attached Madole Proposal.
$4,400.00
6. Added 3 Phase Breakout Time to the Original Precise Grading Plan Fee Additional civil engineering time for separating the Precise Grading Plan (PGP) into three separate phases. See attached Madole Proposal.
