Under the supervision of Gary Kreutziger the MEP staff consists of six plan reviewers. The goal of the MEP staff is to review each set of construction documents with precision and promptness. Currently the MEP reviews are limited to commercial projects located throughout the city and surrounding areas. The staff provide plan review based on the following codes:
2006 International Mechanical Code
2005 NEC
2006 Uniform Plumbing Code
City of San Antonio amendments to these codes are located at the following:
Adopted Code Amendments
When MEP work is being proposed, the following require engineered MEP plans from a professional engineer licensed in the state of Texas:
1. All group A (Assembly) – Theaters, restaurants, bars, churches, Stadiums, etc.
2. All group E (Educational) – Day cares, grades 1st - 12th, religious educational
rooms, etc.
3. All group I (Institutional) – Care facilities, assisted living facilities,
social rehabilitation facilities, etc.
4. Buildings and structures over one story
(Commercial).
5. Buildings and structures 5,000 square feet or more in area.
6. Electrical plans must be engineered when
the total load exceeds 100 KVA single phase, 150 KVA three
phase, or over 600 volts.
For smaller projects outside the scope of the above, your MEP design will be reviewed by the Minor Plans Review team. Please refer to the Minor Plan Review website for more information.
The following are requirements for submittal to Plan Review for engineered MEP projects:
MECHANICAL
HVAC equipment and schedules: Show locations, type, capacity, energy efficiency, and weight/support of all heating, ventilation and air conditioning (HVAC) equipment.
Rated Enclosures: Show or specify wall construction and opening protection where rated enclosures are required (heaters, boilers, etc., over 400,000 BTU; air conditioners over 100 HP, etc.).
Special Equipment: Show special equipment such as kitchen hoods, garage ventilation, paint booth exhaust, automatic fire suppression, etc.
Fire or Smoke Control: Define in specifications or on plans special use of equipment in conjunction with fire or smoke control.
Penetrations of Rated Assemblies: Show method of opening protection and note referenced listing or refer to drawings containing same information.
Special Requirement: Show appurtenances and required details such as flue vent type and size, expansion tanks, blow down systems, protection devices, means for combustion air and special use equipment.
Air Distribution System: Show all duct runs, fire/smoke dampers where applicable, sheet metal gauge thickness for medium and high velocity systems, type and class of non-metallic duct, etc.
2000 International Energy Conservation Code Compliance/Calculations for Mechanical Equipment. Using the COMcheck software,provide Mechanical Reports/Certificate

ELECTRICAL
Utility Site Plan: The site plan should include location of all electrical equipment external to the building envelope, such as: power poles, overhead or underground electric lines, service equipment, pad mount transformers, generators, signs, pole lights, and exterior building lights.
Riser Diagram: The riser diagram should be a complete and comprehensive one-line diagram, including all service equipment, panels, transformers, generators, and fire pumps. The riser should also include all conductor sizes, overcurrent protection sizes, conduit sizes, and ground fault protection at the service if applicable.
Grounding Detail: The grounding detail can be incorporated in the riser or detailed separately; either format should include all conductor sizes, ground rod size, and location of bond. As a minimum the grounding electrode system shall consist of a concrete encased electrode, cold water bond, structural steel bond and grounding electrode. All methods of grounding/bonding should be sized and installed as per NEC article 250.
Interior Electrical Layout: The power plan should include the locations, circuiting, and wiring methods, of all electrical equipment such as panels, transformers, disconnects, elevator equipment, receptacles, etc,
The lighting plan should include the location of all fixtures and switches or other method of control (occupancy sensor, contactor, photo cell, time clock, etc,)All 2000 IECC requirements such as bi-level switching, occupancy sensors, master switches, etc… will be required where applicable.
Load Analysis: The load analysis should be calculated as per NEC article 220, and will need to include and indicate any existing load to assure adequate capacity of a common service, panel, load center, etc…
Panel Schedules: The panel schedules should include frame sizes, main lug or main breaker, feeder size, number of circuits, all overcurrent protection sizes (including main), NEMA classification of enclosure, and indication of any arc fault, ground fault, or shunt trip type breakers.
Fixture Schedule: The fixture schedule should include a fixture description, number of lamps, maximum lamp wattage, installed lamp wattage, and number of fixtures.
IECC Lighting Compliance Certificate: The 2000 International Energy Conservation Code (IECC) is enforced. Com check- EZ versions 2000, 2001, and 2001-90.1 are accepted. For more information on obtaining necessary forms you may visit
http://www.energycodes.gov/
Preparation of Electrical Drawings: A signed and dated Texas P.E. seal will be needed on plans when required by the Texas Engineering Practice Act, or when plans meet the requirements of Section 10-92 (e) of Chapter 10 of the City Code.
All plans not requiring a P.E. seal will need a signed and dated architectural seal or the name and master number of the master electrician responsible for the plans.
Additional Electrical Notes:
1. Once CPS Energy has approved two services to one structure, the required two
hour fire barrier that separates the areas served by each will need to be indicated
on the appropriate architectural drawings as well as the electrical drawings.
2. Rooms containing large equipment as defined by NEC article 110.26 (c) (2) will
need to indicate the correct door swing and
hardware. This information will need to
be shown on the appropriate architectural drawings as well as the electrical
drawings.
3. Disconnecting means for heating equipment covered in article 424 of the NEC and
for Refrigeration equipment found in article 440 of the NEC will be required to be
independently supported off the unit. This requirement will also apply to the
required servicing 120 volt receptacle outlet. Please reference Section 10-93 (1)
(e) & (f) of
Chapter 10 of the City Code for more details.
4. Exterior lighting designs on all commercial structures in addition to meeting NEC
requirements will also need to be in accordance with section 35.396 of the Unified
Development Code (UDC).
Please see the Electrical FAQ for more information.
