Knowledge. Dedication. Reliability.
iDesign Engineering Inc. is a Maryland-based consulting practice providing civil and structural design services for public infrastructure, including highways, bridges, rail, transit, parking facilities, and water resource management. Founded in 2012 by Dr. Joan Wang, it partners with larger companies on critical design tasks. Most staff hold professional engineering licenses and the team continually expands its expertise in transportation, water resources, structural engineering, and GIS.

Focuses on protecting and rehabilitating watersheds throughout the Chesapeake region. The practice delivers custom engineering solutions for runoff control, environmental compliance, and flood mitigation.
Designs and retrofits environmentally friendly stormwater quality treatment measures utilizing low-impact development and environmental site design principles.
Conducts floodplain studies, scour analyses, and advanced engineering computations to analyze watershed behavior and design hydraulic structures.
Manages stream restoration and watershed rehabilitation initiatives to improve local water quality and control erosion.
Delivers comprehensive site planning and construction preparation services for public infrastructure projects. Work ensures compliance with environmental regulations and smooth transition from planning to active construction.
Develops detailed grading and site plans to optimize earthwork, drainage patterns, and spatial efficiency.
Prepares regulatory-compliant sequences and mitigation designs to manage runoff and protect surrounding ecosystems during construction.
Brings public corridors, sidewalks, pedestrian ramps, and crossings into full compliance with federal accessibility standards.
Develops roadway alignments, geometric plans, and roadside safety systems adhering strictly to AASHTO standards. The engineering team manages the entire lifecycle of corridor expansions and safety modernizations.
Designs horizontal and vertical alignments for new highway corridors, lane additions, overpass approaches, and complex intersections.
Evaluates in-service guardrail performance and designs robust containment and end-treatment systems to enhance motorist safety.
Utilizes advanced CAD and BIM modeling platforms to visualize corridor constraints, perform earthwork calculations, and streamline conflict resolution.
Analyzes and optimizes multi-modal movement across regional transportation networks. The practice designs control systems and routing plans that enhance safety and maximize operational efficiency.
Engineers modern mast arm and spanwire signals, including pedestrian upgrades and comprehensive warrant studies.
Develops multi-phase temporary traffic control and construction sequencing plans to maintain safe traffic flow during major infrastructure upgrades.
Analyzes commuting stresses to optimize cycling corridors, safe pedestrian routes, and multi-modal transit connections.
Plans and designs multi-modal transit hubs and support facilities. The engineering team coordinates closely with transit agencies to improve commuter access and operational flow.
Designs heavy-duty pavements, drainage systems, and layout configurations for busy transit centers, bus loops, and rail yards.
Develops specialized drainage, utility, and civil plans tailored to the constrained right-of-way environments of rapid transit routes.
Designs oil-water separators and other runoff treatment systems for fueling facilities within train yards and active transit depots.
Engineers load-bearing systems and protective structures for transportation and public facility networks. Work spans from specialized foundation design to structural inspections.
Designs structural components for bridge replacements, culvert systems, and retaining walls.
Performs real-time health monitoring of in-service bridges and conducts detailed structural condition assessments.
Designs structural framing and load-bearing supports for mounting heavy specialized equipment on buildings.
Integrates spatial analysis into every engineering phase. The practice builds customized mapping applications and geodatabases to track assets and inform design choices.
Constructs and maintains project-specific databases and web indices to store, query, and visualize geographic information.
Uses spatial data to locate, catalog, and evaluate underused pavement areas for watershed crediting programs.
