Structure Designing

DesignLAB International execute and supervise the analysis, design, and document preparation for the building structure and has knowledge of requirements for the load carrying structural system. We are responsible for design of primary structural system, that is "the completed combination of elements that serve to support building's self-weight, applicable live load that is based upon occupancy and use of spaces, and environmental loads such as wind, seismic, and thermal.”

Every part of a building is subject to effects of outside forces - gravity, wind, earthquakes, and temperature changes, to name a few. Throughout history, people have constructed buildings that have withstood these forces over a long period of time, primarily using rules of thumb derived from their own experiences and those of their predecessors. In recent centuries, the scientific and industrial revolutions introduced analytical approaches that allowed designers to go beyond empirical limitations and predict the behavior of building systems and components that existed only in their imaginations. This gave rise to the formalization and specialization of the modern engineering profession, who in turn led to more accurate and cost-effective designs.

We need a site engineer to perform structural engineering functions necessary for the structure to be completed and who has shown experience in the specific specialty. Engineer usually retained by a supplier or subcontractor who is responsible for the design, fabrication, and sometimes installation of engineered elements or by general contractor or subcontractor responsible for construction related services. Common examples of such elements are precast or tilt-up concrete, open web steel joists, pre-engineered cold-formed steel or wood trusses, and metal building systems.

Every project should have a single designated Engineer who establishes the structural design criteria and concepts for the project, but may delegate detailed design of certain portions to us by communicating this information and other requirements on construction documents (drawings and specifications). In such cases, we subsequently prepare calculations and construction documents for delegated work and submit them to Engineers, who verifies if it comply with the specified requirements and is consistent for the project as a whole. Without an Engineer, it is difficult to ensure adequate coordination of design work that is performed by us. This problem often arises in design-build situations when various subcontractors supply their own design services, but there is no Engineer to review the documents that they produce to harmonize those with each other.

We undertake the project before finalization of architectural, mechanical, and electrical systems. We provide valuable input into these decisions, addressing such factors as:

Type of construction—The selection of the structural system (frame, bearing walls, etc.) depends on the function and dimensions of the building, as limited by the building code and any zoning restrictions, as well as the local availability and relative cost of each material (reinforced concrete, precast concrete, reinforced masonry, structural steel, cold-formed steel, wood, etc.).

Column locations—A uniform grid facilitates repetitive member sizes, reducing the cost and increasing the speed of construction. Bay dimensions may also be optimized to minimize material quantities while efficiently accommodating specific space requirements, such as parking garages and partition layouts.

Bracing or shear wall locations—Horizontal forces due to wind, earthquakes, etc. must be transferred down from the superstructure to the foundations. The most efficient means of accomplishing this is usually to provide vertical bracing or shear walls oriented in each principle direction, which must be coordinated with functional and aesthetic requirements for partitions, doors, and windows.

Floor and roof penetrations—Special framing is often required to accommodate stairs, elevators, mechanical chases, exhaust fans, and other openings.

Floor-to-floor heights—Adequate space must be provided for not only the structure itself, but also raised floors, suspended ceilings, ductwork, piping, lights, and cable runs for power, communications, computer networks, etc. This may affect the type of floor system (reinforced concrete beams, joists, or flat plates; structural steel beams or open web steel joists; cold-formed steel or wood joists or trusses) that is selected.

Exterior cladding—The building envelope not only defines the appearance of the facility, but also serves as the barrier between the inside and outside worlds. It must be able to resist wind and other weather effects while permitting people, light, and air to pass through openings such as doors, windows, and louvers.

Equipment and utility arrangements—Large equipment (air handling units, condensers, chillers, boilers, transformers, switchgear, etc.) and suspended utilities (ductwork, piping, light fixtures, conduits, cable trays, etc.) require adequate support, especially in areas subject to seismic activity that can induce significant horizontal forces.

Modifications to existing buildings—Changing the type of roof or roofing material, adding new equipment, and removing load-bearing walls are common examples of renovation measures that require structural input.

We are concerned with providing not only adequate strength for the building, but also serviceability. Beams that deflect excessively under their design loads can cause problems with floor and ceiling finishes, especially those that include brittle materials. A light and inexpensive framing system may exhibit uncomfortable vibrations when subjected to human foot traffic. If high winds cause considerable lateral movement, unacceptable cracks may develop in exterior walls and interior partitions.

We are involved in a building project until construction completes. No set of documents is perfect; review of submittals and firsthand observations at the site may reveal conflicts between disciplines or misinterpretations by the contractor at a point in time when it is still possible to correct them with minimal cost and schedule impacts.
