PROJECT CONSTRUCTION DEVELOPMENT BUDGET
Estimated total Project cost for these improvements is $14,461,475.00 ($892,450.00 for Ben Garza,
$1,774,200.00 for HJ Williams, $8,037,525.00 for Washington Coles, $2,177,300.00 for TC Ayers,
and $1,580,000.00 for the North Beach Trailhead and shared use path). This construction
development budget does not include soft costs for professional consulting or support services, but
does include a construction contingency of 15%.
PROJECT DESIGN DELIVERABLES BY CITY
The scope of services for this proposal has been prepared assuming that the CITY will supply the
following deliverables to the CONSULTANT in a timely manner, which are necessary to complete the
design phase.
1. Topographic Survey — includes but not limited to, Category 6 (per TSPS standards);
established elevations of the Project sites; location of visible improvements within the Project
areas; location (x, y, and z elevations) of visible utilities within the Project areas; location of

within the areas of TC Ayers Park and North Beach Trailhead will affect the reliability
of the survey. Additional survey may be required at a later date to confirm or modify
construction documents prior to 90% submittal and schedule may be affected due to
ongoing construction in these areas.

SCHEDULE ASSUMPTIONS
The schedule for this proposal has been prepared using the following assumptions as a basis for its
preparation.
• All Topographic Survey Data for each site (parks, trailhead, and shared use path) will be
received simultaneously.
• Additional topographic survey may be required for TC Ayers Park and the North Beach
Trailhead, due to ongoing construction activity in these areas. Schedule may be affected by
this need for survey after ongoing construction has been completed.
• Notice To Proceed (NTP) and Executed Contract will be received the same day or one (1)
week after the receipt of the Topographic Survey Data for each site.
• Geotechnical Report will be received prior to the 60% Design Submittal
• Schematic will be submitted, and review comments will be received prior to the 60% Design
Submittal
• All review times including City of Corpus Christi Development Services and TxDOT will be 2
weeks maximum.
If the schedule assumptions are not completed as stated, the schedule is subject to change.
All sites (4 parks, 1 trailhead, and shared use path) shall be combined into a single (1) set of
construction documents. Preparation and submittal of separate construction documents per park,
trailhead, and/or connectivity shared use path is not included in this scope of services.
