REVIEWED:

PURPOSE: 
The Development Services Department is requesting approval of the First Amendment to the Professional 
Services Agreement (PSA) between the City of Tolleson and 4Line Studio, LLC, for professional services related 
to the design and development of the Tolleson Event Center. The Amendment extends the term of the 
Agreement through June 30, 2027, incorporates a fee proposal for project-specific architectural and 
engineering services, and establishes a maximum aggregate compensation amount not to exceed $175,000. 
 
BACKGROUND: 
On September 27, 2022, the City entered into a Professional Services Agreement with 4Line Studio, LLC to 
provide on-call architectural services. The Agreement allows the City to utilize the consultant for architectural 
and related design services on an as-needed basis. This agreement had extension options through June 30, 
2026. 
 
The City acquired the partially completed building located at 9258 West Van Buren Street and is pursuing its 
conversion into the Tolleson Event Center. The project includes renovation of the existing approximately 5,500-
square-foot structure and construction of an approximately 3,500-square-foot addition to create a community 
event facility. 
 
DISCUSSION: 
The proposed First Amendment incorporates a project-specific fee proposal for the Tolleson Event Center. 
Under the proposed scope of work, 4Line Studio, LLC will provide architectural design services and coordinate 
subconsultants for mechanical, plumbing, electrical, structural, civil, landscape architectural, cost estimating, 
food service design, and geotechnical engineering services. 
 
The proposed facility is anticipated to include a ballroom/event space with a capacity of approximately 250 
occupants, meeting rooms, restrooms, bridal room, warming kitchen, business support spaces, outdoor patio 
area, vehicular drop-off area, and additional parking improvements. 
 
The scope of services includes completion of schematic design, design development, and construction 
documents necessary for permitting and future construction of the facility. The fee proposal included with the 
Amendment establishes a total project cost of approximately $171,385 for basic services. To provide flexibility 
for additional services and contingencies that may arise during project development, staff recommends

establishing a maximum aggregate compensation amount not to exceed $175,000. 
 
The Amendment also extends the term of the Agreement through June 30, 2027, to allow sufficient time for 
completion of the design services associated with the project. 
 
BUDGET IMPACT: 
Funding for the proposed services is available within the project budget established for the Tolleson Event 
Center. The First Amendment establishes a maximum aggregate compensation amount not to exceed $175,000. 
 
RECOMMENDATION: 
Staff recommends approval of the First Amendment to the Professional Services Agreement between the City 
of Tolleson and 4Line Studio, LLC, for professional services related to the design and development of the 
Tolleson Event Center, extending the Agreement through June 30, 2027, and establishing a maximum aggregate 
compensation amount not to exceed $175,000.
