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.
Creates detailed architectural representations, parametric families, construction drawings, and visualizations.
Coordinates mechanical, electrical, plumbing, and fire protection systems.
Prepares detailed structural steel shop drawings, rebar detailing, and light gauge steel framing layouts.
Coordinates building envelope and facade models with main structural systems.
Integrates construction sequencing schedules and cost estimation datasets with the spatial models.
Performs multi-trade spatial coordination and clash resolution using advanced virtual tools.
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.
Converts registered laser scan point clouds into editable parametric models and technical drawings.
Captures detailed digital measurements of existing buildings and historical monuments for preservation.
Creates high-fidelity digital replicas of structures to optimize asset lifecycle management.
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.
Drafts detailed horizontal and vertical spatial layouts of new or existing structures.
Prepares comprehensive drawing sets, details, and specifications required for the building construction phase.
Develops large-scale physical layouts and master plans for sites, communities, and infrastructure corridors.
Designs alterations, structural updates, and spatial reconfigurations for existing buildings.
Architects building systems for mechanical, electrical, plumbing, and fire protection infrastructure. The engineering processes ensure code compliance and coordination with structural boundaries.
Engineers building system layouts, sizing ducts, piping, electrical loads, and safety features.
Harmonizes mechanical, electrical, plumbing, and fire protection systems with structural plans to avoid conflicts.
Provides pre-construction support, constructability reviews, scheduling, and value engineering. The practice oversees risk management and cost control from initial planning to project closeout.
Lays out preliminary schedules, logistics plans, and initial budgets to de-risk projects before site activities begin.
Analyzes design documents to identify construction hurdles and optimization opportunities prior to bid.
Optimizes structural and mechanical systems to reduce material and labor costs without compromising quality.
Formulates precise material take-offs and labor estimates to establish predictable construction budgets.
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.
Manages code compliance and submittals for rooftop and ground-mounted solar energy systems.
Secures building, occupancy, and specialty permits for hotels, retail, and office environments.
Facilitates utility and cellular infrastructure approvals with local regulatory authorities.
Consults on the lifecycle operations of complex assets using building assessments, predictive maintenance strategies, and database handovers. Work focuses on optimizing equipment longevity.
Evaluates the physical and structural integrity of building components to establish capital planning budgets.
Tracks equipment serial numbers, warranties, and maintenance histories across major building portfolios.
Advises building operators on resource allocation, energy efficiency, and preventative maintenance schedules.
Integrates spatial models with facility systems to enable interactive operations tracking.
Delivers detailed technical drawings, legacy conversions, and spatial layouts. Work supports structural, architectural, and building systems coordination.
Transforms legacy 2D drawings into intelligent, multi-dimensional virtual design models.
Produces precise vector-based architectural, structural, and mechanical drawings from sketches or site notes.
