Specialty Services

Access Solutions 
Our Access Solutions engineering services provide safe, practical, and efficient temporary access for challenging construction projects. We specialize in the design of system and frame scaffolds, suspended scaffolds, swing stages, construction hoists, mobile transport and work platforms, elevated work platforms, and overheard protection systems. Our experience includes access solutions for historic buildings, high-rise structures, industrial facilities, and complex building envelope restorations. Every solution is tailored to the project's structural, logistical, and scheduling constraints, helping contractors work safely, maintaining productivity, and minimize impacts to operations and the public.

Demolition Plans and Procedures
Our Engineers have conducted pre-demolition surveys of building due to their close proximity to demolition operations. Observation reports include a record of the general preexisting structural condition of the buildings before demolition. We also work with demolition contractors to review and develop demolition procedures for buildings to determine if shoring is required. Typically, we are also retained to perform a post-demolition surveys to re-inspect for changed conditions. We have assisted with evaluation of existing buildings where portions of the buildings were to remain and designed temporary shoring for façades. We closely monitor the remaining portions of the buildings for property managers on a routine basis to determine if there are any changes or movement.

Shoring
The firm has a long history of working for Owners, Contractors, and Specialty Scaffolding Companies to design shoring to prevent structures from collapse, or to allow construction to proceed in rehabilitation projects. In rehabilitation projects, there are many instances where bearing walls need to be removed or major changes to the structure are required. Ryan Biggs Clark Davis has designed temporary shoring to allow the work to proceed safely.

Stone Anchor Design
We have served as Delegated Design Engineer to design anchors and supports for dimensioned stone and other specialty cladding systems for new and existing buildings. For existing buildings, Ryan Biggs Clark Davis has performed field testing of proposed anchors as a basis for design. Materials have included limestone, granite, marble, cast stone, brownstone, and terra cotta for walls, soffit panels, arches, lintels, jambs, sills, copings, and other accent features for both interior and exterior applications. Anchor materials have included stainless steel straps, rods, pins, angles, and proprietary cladding systems.

Structural Lifting
The firm is involved in many aspects of bridge construction including jacking (or structural lifting operations). When acting on the owner’s behalf, Ryan Biggs Clark Davis specifies the jacking. When acting on the contractor’s behalf, we develop the plans and details for the contractor to implement. Bridges may require jacking or shoring to strengthen existing bridge members, to replace a deteriorated member or existing bearing, to replace a failed or damaged member, or to aid in the erection of the structure.

Cold-Formed Metal Framing
Ryan Biggs Clark Davis provides structural engineering design and detailing of light-gauge cold-formed metal-framed (CFMF) structures. Acting as either the design Engineer of Record or as the delegated engineer responsible for provision of engineered shop drawings and component design calculations, Ryan Biggs Clark Davis provides services including engineering for multi-story loadbearing CFMF; plywood/metal panel/gypsum shear walls and light-gauge strap braced frames for wind and seismic force resistance; cladding and curtain back-up assembly framing; and interior non-loadbearing partitions, supports, and assemblies. The CFMF design can be seamlessly coordinated with concrete, steel, and masonry components and supporting structures.
