B&A - TYPICAL DESIGN SERVICE

MECHANICAL / PLUMBING - Typical design tasks include:

• Meet with the project representatives to determine the scope of work and project goals. Gather available information such as as-built drawings then visit the site to verify existing conditions.
• Our mechanical designer would then calculate heating and cooling loads based on environmental factors, building construction, number of people and equipment/appliances to determine sizing requirements for HVAC equipment.
• Prepare a schematic design/concept plan to review with the client, architect and structural designers for equipment sizing, location and layout. Early in the schematic design phase we discuss the system options. We have experience with nearly every type of HVAC system including: central plants with boilers and chillers; four pipe HVAC distribution systems, thermal energy storage systems, package units and split systems. We are also capable of designing more complex systems including laboratory designs, clean rooms; biosafety labs with C.D.C. requirements, industrial process, hazardous material rooms, and complex exhaust systems, etc. These complex systems are mentioned because we stay current on the latest technologies and look for opportunities to apply these technologies.
• Once we all agree on the best system, B&A will proceed with a detailed design to provide a cost effective engineering design of the HVAC system to complement the facility requirements, conform to applicable codes and California Title 24 requirements. We then specify HVAC equipment locations, air distribution plan, and zone temperature control plan, BMS control systems and exhaust system.
• Prepare Mechanical Title 24 documents and prepare submittal for agency approval.

In addition to our mechanical HVAC designs we also provide plumbing and electrical designs as follows:

• Plumbing Plan - Prepare calculations and design new plumbing systems including: hot and cold water piping layout, waste/vent piping, condensate drains, roof/deck drains, gas piping, pipe sizing, fixture selection and water heater selection/sizing. If required we have the ability to design complex industrial systems including: air compressor plants, process piping, industrial waste streams with neutralization stations, monitor systems, process gasses (nitrogen, oxygen, argon), etc.
• Site Plumbing - Provide a design for point of connection (POC) to the site utilities located 5' outside of the building perimeter. The plumbing site utilities typically include: gas, water and sewer. These design efforts are coordinated with the civil engineer, architect and utility service companies. Utility gas requirements for the site are based on heating loads and other requirements and water/sewer requirements based on the water usage (fixture count).
• Fire protection (plumbing) - B&A has designed combined standpipe, combination and wet standpipe systems. Components include fire department connections, post indicator valves, flow and tamper switches, pressure switches, etc. Designs include instructions and specifications to the contractor to hire a C16 licensed design build contractor to install the sprinkler system. B&A also provides risers and a point of connection for the sprinkler system.

ELECTRICAL

A sample of our design strengths include:

Electrical service upgrades - we have performed hundreds of electrical service upgrades for school campuses, industrial facilities, buildings including new construction and modernization. Typically we coordinate the following:

• Verify existing electrical capacity.
• Coordinate the new electrical service and transformer location with the utility company; coordinate telephone and cable TV service with the serving utilities (as required).
• Provide a layout for the electrical room or main switchboard yard.
• Provide a Single Line Diagram
• Provide load calculations and panel schedules.
• Provide short circuit calculations and device tripping coordination studies (if size of project warrants these items).
• Design the physical locations of the main service, distribution switchboards, and motor control centers.
• Provide a site electrical plan showing distribution of the electrical power, low voltage, data and fire/life safety.
• Provide design for telephone backboard, FACP control panel, TV/cable headend and security equipment, data main distribution frame and local distribution frames.
• Provide parking lot and other exterior lighting controls and inverter system for egress lighting (if required)

Power and Lighting - We have provided power and lighting designs for thousands of areas including: classrooms, offices, egress lighting, parking lots, stadiums, industrial facilities, hazardous areas, clean rooms and others.

Safety and Technology - we have completed many S&T projects. Systems include data networking, data cabling drops (Cat 5E), PA, power upgrades, telephone, security smart podiums in lecture halls and clock systems.

Fire Alarm - we completed hundreds of Fire Alarms projects providing designs for complete addressable, fully automatic fire alarm systems with smoke detection, heat detection, audible alarms, strobes and manual pull stations. The Fire Alarm systems are provided with battery back-up power.

Emergency Generators - Many of our projects include emergency generators.

Other Electrical Designs -

• Computer centers

• High tech pharmaceutical, healthcare, research, industrial and manufacturing clients

• Prepare Title 24 calculations and forms.

• LEED designs

• High voltage substations for industrial facilities and pump stations.

General

• Drawings - Drawings will be prepared in AutoCAD format consistent with the client's base drawings. FTP, email, CD or other means as directed by the client can be used to transfer files during the design process.
• Meetings - We attend meetings as needed.
• Corrections to comply with review comments by the owner, DSA, Department of Building and Safety and by others are included in our services

Construction Support

      Construction support typically includes:

• Review of submittals and shop drawings, responses to contractors' RFI's, review of contractors change order requests and field meetings as required.
• Site visit at each of the following phases of construction:
  a. Underground work completed but while trenches are still open and before slabs have been poured.
  b. Rough-in of HVAC, plumbing and electrical has been completed but walls and ceilings haven’t been covered.
  c. At end of construction to provide a final punch list.
• Incorporate as-built information into drawings after construction.

FULL SERVICE PROJECT MANAGEMENT
Many of our clients prefer one stop shopping for design services.
A typical example follows:

• Meet with the project representatives to determine the scope of work and  project goals. Gather available information such as as-built drawings then visit the site to verify existing conditions.
• Discuss the project with the end users.
• Select a team of experts uniquely qualified for the specific project tasks.
• This may include architectural, civil, structural, environmental, etc. 
• Benefit - Aware of the big picture (keep project goals in focus, maintain schedules and budgets)
• Partner with client to provide one stop shopping

Note: The above listing of services are examples. Not all services are provided on every project, but are provided on projects as per each project's client-approved contract.
