Ground-up Commercial Buildings

A ground-up construction project is building a structure completely from scratch, where nothing existed before.

We can assist you in every step: from site survey to structural and MEP design. Our engineers are well-versed in complex structures and deliver optimized plans and calculations according to design codes and regulations, making sure you get a permit.

Load Bearing Walls

Load Bearing Wall Removal

Removing a wall may grant more open space, but not every wall can be easily removed: some of them are carrying a load and require special measures and calculations.

We will help you identify those walls and provide plans that preserve the stability of the building.

Seismic Retrofit Engineering

Seismic retrofitting is the modification of existing structures to make them more resistant to earthquakes or similar natural disasters. We perform a site inspection to determine the seismic retrofit needs and offer designs to enhance the structures, helping you to obtain a permit for your project.

Structural Calculations

Structural Calculations

While architecture defines the appearance of a building, structural engineering ensures the building stands up and can withstand heavy winds, earthquakes, or gravity loads. Structural calculations are the math behind this ability, and determine the properties of columns, joists, beams, slabs, trusses and other members that comprise a building.

Our structural calculation follows local building codes, therefore not only ensures you can get a permit but also consider value engineering to cut down actual construction costs.

Pool Engineering

Building a swimming pool is subject to safety measures as well as local codes and permit requirements. A properly designed pool supports the soil around it, thereby preventing cracks and leaks.

We offer structural as well as MEP design services for several different swimming pools, ranging from residential swimming pools and community pools to hotel pools, high school pools, college, and university pools.

Warehouse Design

Warehouse Design

Warehouse design is a specialty of S3DA Design, as such projects often require both structural as well as Mechanical, Electrical and Plumbing (MEP) designs, particularly for HVAC systems.

Our designs emphasize safety and development according to regulations while cutting down costs through value engineering. As a single source of both structural and MEP design, we also heavily reduce design clashes, saving valuable time and resources.

Data Center Design

Data Center design is another specialty of our company, as it relies heavily on electrical design, HVAC systems, and plumbing. Safety and efficiency are of utmost importance and proper ventilation has a direct effect on the costs. The buildings also need seismic retrofitting and may be enhanced by adding solar energy to reduce power consumption costs.

We are proficient in all the above fields, and being a single source of responsibility means utmost efficiency, time savings, and cost reductions for our clients who will not need to deal with design clashes, extra costs, or coordination between multiple parties.

Data Center Design
Mixed-Use

Mixed-Use

A mixed-use building combines several functions into one structure. For instance, parts of a building may be devoted to hotel rooms while other parts are used for residential units and commercial services.

S3DA Design has successfully designed mixed-use buildings, including the 73,000-sqft four-story complex Imperial Beach Blue Wave project, which includes hotel rooms, residential units, underground parking garage, shops, a restaurant, and an office. We were deliberately selected because of our vast experience with different kinds of buildings and our ability to deliver structural and MEP design simultaneously.

Restaurant Design

Restaurants differ from other kinds of buildings because of the importance of their kitchen. A kitchen must be safe, competent, easy to maintain, and functional. Designers must prioritize ventilation systems, logistical necessities, and delivery and storage requirements.

Restaurants need extra expertise from MEP designers, and we are uniquely positioned to develop such plans as we offer both structural and MEP design.

Restaurant Design
Foundation Engineering

Foundation Engineering

The foundation transfers the load of the building to the ground and anchors against wind and earthquake. A strong foundation is crucial for a building to last long, therefore it must be protected from cracks, settling or sloping.

Our structural design engineers offer professional plans to protect your foundation against such damages, and will calculate for wear and tear and imperfect soil conditions.

Decks and Patios

Some of our clients need help, deciding if a deck would be suitable for their outdoor space or a patio. Luckily, we are experts in both and can help you decide based on a number of factors including budget, location, purpose, size, materials and maintenance.

Our engineers will help you with the design, starting with the foundation up to the frame and stairs. We help you choose the material that will last long without damaging the appearance of your deck or patio.

HVAC

The HVAC system is a key mechanical component that puts you in control over temperature and humidity. HVAC systems are one of the most expensive parts of a building’s operation, therefore an efficient design is mandatory to minimize your energy and gas bills while maintaining a great result.

Our company’s specialists ensure that not only do the HVAC designs provide maximum efficiency, but also comply with building codes to ensure quick and pain-free city approval. The design encompasses multiple levels including floor plans, air and water riser diagrams, equipment specification, and construction requirements.

Some of our HVAC services include mechanical drafting and design, mechanical detailing, 3D REVIT modeling, schematic heating, and cooling system design, heating and cooling equipment selection heat loss and/or gain calculations, plant room layout design, and duct layout drawings.

Electrical design

Electrical Design

Electrical design is the process of planning and creating electrical equipment such as electrical components, lighting equipment, power systems, mechanical powers, panel board schedules, electrical riser diagrams, and telecommunications infrastructure.

An accurate electrical design plan is crucial to accurately measure the energy usage of each component in the building, allowing to optimize for maximum efficiency. Our engineers are experts in electrical design and are well-versed in alternative energy sources such as solar panels, helping you to achieve high efficiency with your plan and reduce energy costs as well as maintenance requirements.

Our electrical design services include electrical schematics, power and lighting plans, interior lighting and exterior lighting, electrical site plans, riser diagrams, electrical panel schedules and distribution panels, wiring diagrams and power distribution systems.

Plumbing Design

A plumbing design addresses two systems; one that supplies water and one that gets rid of waste. An efficient plumbing system provides water to the necessary sections of a building with the right flow and pressure while saving water and energy resources. An accurately sized system can minimize pumping costs, and an efficient water usage system reduces the heating bill. The system can be further improved via water-saving upgrades such as rainwater collection tanks, low-flow plumbing features, and greywater recycling systems.

Our engineers develop professional plumbing designs adhering to local design codes while being optimized for maximum efficiency. We offer plumbing and drainage drafting services design and drafting services for domestic water, plumbing set up of natural and LP gas piping drafting, compressed air and medical gas system plan drawings, demolition and existing plan drawings, isometrics, riser diagrams, schematics, and schedules.

Green Construction

Title 24

Title 24 is a collection of energy standards created by the California Building Standards Commission in 1978, that strives to make buildings more energy-efficient and reduce greenhouse gas emissions. The standards are updated every three years. In 2020, the main purpose is boosting energy efficiency, saving consumers money, and improving air quality.

S3DA Design has experienced engineers who design to meet those goals, using the latest technology and years of experience. Some of our Title 24 services include Title 24 calculation, remodeling lighting, Title -24 envelope, and Title 24 mechanical.

Solar Design

Solar power is increasingly popular, particularly in California which has made solar power mandatory for newly designed homes as part of Title 24, Part 6. Solar power reduces your energy bills, however, installing the system and getting it right is challenging.

Our engineers assist you with picking the right system and designing for efficiency. As MEP and structural design experts, we are particularly well-positioned to take care of all such requirements from start to finish.

Fire protection

Fire Protection

Fire is the greatest enemy of buildings, thus it is important to prepare and protect against it. There are strict fire protection guidelines, and designs must meet local codes.

Our experts design for fire protection with maximum efficiency and minimum costs in mind, incorporating measures to prevent fire or minimize damage in case of an outbreak. We design for fire alarm systems containing the necessary sensors and devices to detect fire, as well as accommodate fire exists.
