Engineering Standards
Section 9 – Structural Design Requirements
9.01 General
A. The Design Engineer of record shall bear the sole responsibility for meeting the engineering
standard of care for all aspects of the design and providing a design that’s required by the sitespecific
conditions and intended use of the facilities.
B. For the purposes of this section of the Engineering Standards, the following items shall be
considered structures: bridges, foundations, retaining walls (structural and gravity), headwalls and
wingwalls, culverts, slopes and embankments, and screening walls.
C. The City’s review of any structural design is limited to determining whether the construction
plans are in general compliance with the City’s Master Plans and Engineering Standards. The
City’s review and release of the construction plans does not represent that the City has reengineered
or verified the engineering of the proposed improvements.
D. The structural design must be signed and sealed by a structural engineer or civil engineer
competent in structural engineering licensed in the State of Texas. The Design Engineer is
responsible for all engineering and recognizes that specific site circumstances or conditions may
require improvements constructed to exceed minimum standards contained in the City’s
Engineering Standards. The Design Engineer is responsible for the applicability and accuracy of
the construction plans and specifications.
E. Walls shall be permitted and constructed in accordance with all requirements of these
Engineering Standards. Third-party inspections shall be performed during construction, and
reports provided to the City. A third-party shall certify wall was constructed in general
compliance with the City-approved plans and specifications, and a certification shall be provided
to the City.
9.02 Code Requirements
A. All structural design shall comply with the City’s currently adopted version of the International
Building Code.
B. The design and construction of structural concrete for buildings and where applicable in nonbuilding
structures shall be provided in accordance with the requirements of the current version of
“Building Code Requirements for Structural Concrete (ACI 318)” as published by the American
Concrete Institute.
C. Placing reinforcing steel in reinforced concrete structures shall be provided in accordance with
the requirements of the current version of the “ACI Detailing Manual (ACI 315)” as published by
the American Concrete Institute.
D. The design and construction of concrete tanks, reservoirs, and other structures commonly used in
water and wastewater treatment works where dense, impermeable concrete with high resistance to
chemical attack is required shall be provided in accordance with the requirements of the current
version of “Environmental Engineering Concrete Structures (ACI 350)” as published by the
American Concrete Institute. This code places special emphasis on structural design that
minimizes the possibility of cracking and accommodates vibrating equipment and other special
loads. ACI 350’s minimum requirements for proportioning of concrete, placement, curing, and
