Structural Engineering

Richard J. Driscoll, Consulting Engineer (RJDCE) provides a broad array of structural engineering services, including several non-traditional offerings that assist project stakeholders to manage risk and uncertainty associated with existing structures, below-ground construction and urban sites. RJDCE’s approach to structural engineering is informed by the practice’s experience with foundations, construction system and forensic investigations to improve performance and control construction costs and risk of structural systems.

“Site-Structural” Engineering for the Urban Environment

Construction in the urban environment, especially below ground, presents unique technical challenges and risks that require engineering to interface the proposed construction to its site and surroundings. These challenges and risks are compounded when dense urban development requires new facilities to be constructed below ground.

This “site-structural” engineering includes selection and design of foundations and temporary protective works, assessment and monitoring of adjacent structures and investigation of construction damage. Many traditional structural engineering firms do not offer these services and fewer still offer them as a holistic, interdisciplinary practice area. Read More…

Delegated Design

“Delegated Design” is the means through which the Design Professional of Record (DPR) passes design responsibility for certain details or elements of a project to the Contractor. RJDCE has experience providing contractors with a variety of design services, including Delegated Design submittals for permanent structural and foundation elements and temporary structural systems interfacing with permanent work.

Temporary Structures for Construction

Construction projects often require the design, construction and use of temporary works to provide access or protection to workers or the public, to protect adjacent structures or to support temporary loads during construction. Temporary works often include structures, such as excavation support systems, underpinning, scaffolds, bracing and shoring, formwork, falsework, work platforms, decking, roof protection and structures used in on-site contractor facilities. RJDCE can provide concept development, performance specification, analysis, design and review monitoring of a variety of temporary structural systems used in construction. Read More…

Existing Structures

Analysis and design of modifications to an existing structure are substantially different from designing a new structure.  RJDCE can help clients assess and manage the risk associated with a variety of existing structures, including underground structures, foundation components and retaining walls. The practice presents experience observing and investigating existing structures, foundations and underlying subsurface conditions, analyzing the effect of new loads or compliance with current standards and developing rehabilitation or repair plans.
