Capabilities

BIM/VDC Services

Service website

Provides virtual design and construction modeling across architectural, structural, mechanical, electrical, plumbing, and facade disciplines from schematic design through facility operations. The team coordinates detailed digital models up to level of development 500, incorporating scheduling, cost estimation, and lifecycle operations data.

  • Architectural BIM Modeling

    Creates detailed architectural representations, parametric families, construction drawings, and visualizations.

  • MEP BIM Services

    Coordinates mechanical, electrical, plumbing, and fire protection systems.

  • Structural BIM Services

    Prepares detailed structural steel shop drawings, rebar detailing, and light gauge steel framing layouts.

  • Facade BIM

    Coordinates building envelope and facade models with main structural systems.

  • 4D/5D BIM

    Integrates construction sequencing schedules and cost estimation datasets with the spatial models.

  • BIM Coordination and Clash Detection

    Performs multi-trade spatial coordination and clash resolution using advanced virtual tools.

3D Laser Scanning

Service website

Deploys high-precision reality capture to establish physical dimensions of existing conditions, supporting renovations, restorations, and digital twin assets. Deliverables include registered point clouds, intelligent as-built models, and coordinate drawings.

  • Scan-to-BIM Conversion

    Converts registered laser scan point clouds into editable parametric models and technical drawings.

  • Historical Structure Scanning

    Captures detailed digital measurements of existing buildings and historical monuments for preservation.

  • Digital Twin Modeling

    Creates high-fidelity digital replicas of structures to optimize asset lifecycle management.

Architectural Engineering Services

Service website

Integrates aesthetic building design with structural and mechanical engineering principles for residential, commercial, and government projects. Work flows from space planning through formal technical documentation.

  • Floor Plans and As-Built Layouts

    Drafts detailed horizontal and vertical spatial layouts of new or existing structures.

  • Technical Drawings and Detailing

    Prepares comprehensive drawing sets, details, and specifications required for the building construction phase.

  • Urban Space Planning

    Develops large-scale physical layouts and master plans for sites, communities, and infrastructure corridors.

  • Renovation and Remodeling Support

    Designs alterations, structural updates, and spatial reconfigurations for existing buildings.

MEP Engineering and Design

Service website

Architects building systems for mechanical, electrical, plumbing, and fire protection infrastructure. The engineering processes ensure code compliance and coordination with structural boundaries.

  • Mechanical, Electrical, and Plumbing Design

    Engineers building system layouts, sizing ducts, piping, electrical loads, and safety features.

  • Trade Systems Coordination

    Harmonizes mechanical, electrical, plumbing, and fire protection systems with structural plans to avoid conflicts.

Construction Management

Service website

Provides pre-construction support, constructability reviews, scheduling, and value engineering. The practice oversees risk management and cost control from initial planning to project closeout.

  • Pre-Construction Planning

    Lays out preliminary schedules, logistics plans, and initial budgets to de-risk projects before site activities begin.

  • Constructability Review

    Analyzes design documents to identify construction hurdles and optimization opportunities prior to bid.

  • Value Engineering

    Optimizes structural and mechanical systems to reduce material and labor costs without compromising quality.

  • Project Estimation

    Formulates precise material take-offs and labor estimates to establish predictable construction budgets.

Permit Facilitation and Expediting

Service website

Coordinates with municipal jurisdictions and regulatory bodies across multiple states to secure building clearances. The team manages submittals for commercial developments, solar arrays, and signage.

  • Solar Permit Expediting

    Manages code compliance and submittals for rooftop and ground-mounted solar energy systems.

  • Commercial and Hospitality Permits

    Secures building, occupancy, and specialty permits for hotels, retail, and office environments.

  • Telecom Permit Expediting

    Facilitates utility and cellular infrastructure approvals with local regulatory authorities.

Facilities Operations Management

Service website

Consults on the lifecycle operations of complex assets using building assessments, predictive maintenance strategies, and database handovers. Work focuses on optimizing equipment longevity.

  • Facility Condition Assessment

    Evaluates the physical and structural integrity of building components to establish capital planning budgets.

  • Asset Management

    Tracks equipment serial numbers, warranties, and maintenance histories across major building portfolios.

  • Operations and Maintenance Consulting

    Advises building operators on resource allocation, energy efficiency, and preventative maintenance schedules.

  • BIM Facility Management

    Integrates spatial models with facility systems to enable interactive operations tracking.

Computer-Aided Design Drafting

Service website

Delivers detailed technical drawings, legacy conversions, and spatial layouts. Work supports structural, architectural, and building systems coordination.

  • CAD to BIM Conversion

    Transforms legacy 2D drawings into intelligent, multi-dimensional virtual design models.

  • 2D Technical Drafting

    Produces precise vector-based architectural, structural, and mechanical drawings from sketches or site notes.
