Construction Engineering

LBYD’s Construction Engineering Division bridges the gap between what is shown on the Contract Documents and the design needs of the General Contractor.

Our staff has intimate knowledge of how buildings and other structures are designed across all building materials. This gives us the unique advantage to efficiently communicate with the Structural Engineer or Architect to bring their vision and design intent to fruition.

Working on the contracting side of the fence we are quite accustomed to react quickly to schedule demands.

LBYD has a team of specialty engineers with over 25 years of experience in the industry.

We can provide services as Specialty Structural Engineering Services (SSE) for Delegated Design items or work directly to support the General Contractor during construction.

Structural Steel Connection Design

Structural steel connections can have elaborate loading and complex geometry. LBYD has extensive knowledge of steel connection design, fabrication practices, and steel detailing. We work closely with steel detailers, fabricators, and erectors to provide designs that work well with the fabricator’s shop practices and can be erected in the field safely and efficiently.

Our staff has over 25 years of experience in the industry and have authored many publications and given seminars on connection design topics. Our capacity allows us to take on projects large & small with a dedicated team for your project.

Our standards and deliverables have been proven to be cost-effective and easy to understand to the user – from the Steel Detailer to the Structural Engineer of Record (SEOR).

We employ the latest ‘state-of-the-art’ software in our design, however, our experience also allows us to work on highly-complex joints outside of the limits of any design software. Our software capabilities include:

  • Ram Connection
  • Idea Statica
  • Trimble Connect / Tekla Structures
  • Qnect Collaboration

Structural Design of Stair and Handrail Systems

Stair and handrail systems are often a Delegated Design item that fall on the miscellaneous steel fabricator to provide. LBYD has extensive experience in the design of stair and handrail systems. We can provide designs that are code-compliant and meet the intended performance requirements for strength and serviceability.

Considered as architectural components, stair and handrail systems must be designed to be attached to the primary building structure. We can leverage our structural steel connection design experience to do so safely and efficiently.

We can provide design of these structures in materials such as steel, stainless steel, aluminum, bronze, and glass.

Temporary Structures & Scaffolding Design

Temporary structures often require specialized design to facilitate repeated erection and disassembly while also optimizing pieces for shipping and handling. LBYD has extensive experience in the design of temporary structures from construction sites to sporting events.

We leverage our experience in building design, aluminum structure design, and erection engineering to provide the design that best fits the needs of the owner and the erector. Our temporary structure experience includes:

  • Hospitality structure design
  • Scaffold design
  • Temporary grandstand design
  • Temporary seating support design

Aluminum Structures Design

LBYD provides design support to aluminum fabricators that primarily service the water and wastewater industry. We assist the fabricator with their shop drawings and provide calculations for structures such as stairs, mechanical platforms, and handrail in aluminum.

Wall Shoring Design

Walls built from Concrete Masonry Units (CMU) or Cast-in-Place Reinforced Concrete may often require to be shored for lateral loads such as wind or seismic. LBYD can work with the subcontractor to provide the shoring design for these walls including attachments and specifying ‘dead men’ or other types of anchoring and improve the safety of…

Cold-Formed Metal Framing Design

The structural back-up for a façade is routinely provided by cold-formed metal framing (metal studs). These systems are often a Delegated Design item and are designed to withstand lateral loading such as wind and seismic, but they must also be stiff enough for the deflection requirements of the outside veneer shown on the architectural drawings. LBYD works with metal stud suppliers to provide drawings for submittal to the Structural Engineer of Record for cold-formed metal framing systems. We also can provide design of ‘load-bearing’ systems where the metal studs are also supporting the gravity system of the structure.

Enhanced Steel Integration (ESI)

Structural steel can often be the contractor’s largest purchase throughout the construction of a building. Enhanced Steel Integration (ESI) is a project delivery method where LBYD coordinates with a steel detailer during the design phase to provide a partially connected steel detailing model alongside the construction documents.

We leverage our experience in building design and steel connection design to jumpstart the detailing of the primary structural steel and its connections while construction documents are still in design. The ESI steel model is a fabrication level model ready for architectural, MEP, and miscellaneous steel coordination immediately upon receipt of the construction documents.

The ESI project delivery method reduces RFIs, accelerates submittal reviews, tightens steel bids, and shortens the time from NTP to steel fabrication. Any project with steel on the critical path should consider the ESI project delivery method with LBYD.

Erection Engineering

During construction environmental loads, such as wind and seismic, are typically not considered by the Structural Engineer of Record. LBYD has experience working with the General Contractor and the Steel Erector to provide engineering support for the stability of the structure during these temporary loading conditions. Below is a listing of our Erection Engineering services:  

  • Staging plans showing crane locations
  • Temporary bracing plans and connection design
  • Lifting plans and rigging
  • Critical lift plans
  • Shoring design & foundations
  • Dunnage/cribbing design
  • Lifting lug design
  • Spreader beam design
