Advanced computer modeling and simulation provide precise performance predictions. Independent verification and peer review ensure quality and validity. Technical reports present findings and recommendations clearly supporting stakeholder understanding and informed decisions.

Feasibility Studies & Project Planning

Feasibility studies serve as the foundation for major projects, answering critical questions before significant money is invested. Can you build on this site? Will the design meet all regulatory requirements? What will it cost? How long will it take? We investigate site conditions thoroughly: soil boring, geotechnical analysis, environmental assessment, and utility availability. We evaluate program requirements and design standards applicable to the project. We estimate costs with sufficient accuracy for budgeting decisions. We identify risks that might affect project success.

For military projects, feasibility studies address anti-terrorism requirements, hardened structure principles, and federal security protocols. For nuclear facilities, feasibility studies evaluate seismic design requirements, redundancy needs, and regulatory compliance complexity. For infrastructure projects, feasibility studies analyze environmental impact, permitting requirements, and operational integration. Our feasibility reports provide comprehensive analysis supporting confident project decisions. We identify viable alternatives with their respective trade-offs, enabling informed comparison and selection.

Cost estimating for feasibility studies begins with parametric analysis—cost per square foot, cost per unit capacity, or other appropriate metrics. As project definition improves during design development, estimates become more detailed and accurate. We include contingency for uncertainty and escalation for time delay. We identify cost drivers and opportunities for cost reduction. By project completion, detailed cost estimates support accurate budgeting and financial planning.

Geotechnical Investigation & Site Characterization

Foundation design begins with understanding subsurface conditions through geotechnical investigation. We conduct soil boring programs determining soil type, stratification, and properties at depth. We perform laboratory testing on soil samples determining bearing capacity, settlement characteristics, and other design parameters. We evaluate groundwater conditions and their potential impact on construction and long-term performance. We assess potential environmental contamination and remediation requirements. For sites with challenging geology—karst conditions, unstable slopes, weak soils—we develop specialized investigation and analysis programs.

Our geotechnical reports provide clear documentation of subsurface conditions and design recommendations. We present boring logs graphically showing soil profile, boring depths, and soil properties. We provide recommendations for foundation type, design depths, bearing capacity, and anticipated settlement. For challenging sites, we recommend additional investigation, specialized foundation designs, or ground improvement. Our recommendations are based on investigation results and professional judgment, providing defensible guidance for design decisions.

Engineering Analysis & Structural Design

Engineering analysis uses advanced computational methods to evaluate complex structural systems and challenging conditions. For complex buildings or infrastructure, three-dimensional models are developed incorporating actual geometry, material properties, and loading conditions. We perform linear analysis for most conditions and non-linear analysis when structural behavior is more complex. We evaluate multiple load combinations: dead load, live load, wind, seismic, snow, and other applicable loads. We calculate stresses, deflections, and safety factors ensuring design safety and performance.

Design optimization balances safety, performance, cost, and constructability. We analyze multiple design approaches, comparing costs and benefits. We optimize member sizes, connection designs, and systems integration. We incorporate feedback from constructability reviews. We verify designs meet applicable building codes and project-specific requirements. For military projects, we ensure compliance with hardened structure requirements. For nuclear projects, we confirm seismic design and redundancy requirements are met. Our final designs are defensible, documented, and ready for construction implementation.

Technical Studies & Problem-Solving

Technical consulting addresses specific questions and problems during any project phase. Does the existing structure have adequate capacity for intended use? What's the impact of site geology on design? Can the design withstand the specified loading? What's the best approach to solving this technical challenge? We conduct targeted analyses answering these questions with clarity and confidence. We review competitor designs and analyze their approaches. We investigate failures or anomalies determining root causes and corrective actions. We provide expert opinions supporting design decisions and project advocacy.

Technical reports document our analysis, findings, and recommendations. Reports include executive summaries for decision-makers and detailed technical sections for engineers. We include figures, calculations, and supporting data demonstrating analysis rigor. Reports are peer-reviewed ensuring accuracy and completeness. Final reports are signed by professional engineers licensed in the relevant jurisdictions, demonstrating professional accountability. Our technical reports provide authoritative guidance supporting informed decision-making.

Regulatory Coordination & Code Compliance

Design services include regulatory coordination ensuring designs meet all applicable codes and standards. We interpret building code requirements and project-specific standards. We coordinate with regulatory agencies when designs differ from standard practice or when variances are required. We document our code compliance verification in technical reports. For military projects, we ensure compliance with UFGS (Unified Facilities Guide Specifications) and military design criteria. For nuclear projects, we verify compliance with applicable nuclear safety standards and regulatory requirements. For projects in foreign jurisdictions, we navigate local building codes and international standards.

Permitting support includes identifying permitting requirements, developing required documentation, and coordinating with permitting authorities. We prepare technical reports supporting permit applications. We respond to permit agency questions and develop solutions to address concerns. We maintain awareness of environmental requirements, accessibility standards, and other regulatory frameworks. Complete permitting support minimizes delays and ensures designs are permittable before construction begins.

Advanced Analysis & Modeling

We utilize advanced analysis tools and techniques including finite element analysis (FEA) for complex structural problems, computational fluid dynamics (CFD) for HVAC optimization, and specialized software for specific applications. Three-dimensional models are developed for complex geometry. Loads are applied realistically. Boundary conditions are accurately specified. Analysis results are verified through parametric studies and comparison with analytical solutions. We provide visualization of analysis results supporting stakeholder understanding of structural behavior and design performance.

For novel or challenging problems, we develop specialized analysis approaches validated through testing or comparison with known solutions. We document analysis assumptions, methods, and validation. Results are presented clearly with appropriate uncertainty quantification. Our analysis work is defensible, thorough, and based on sound engineering principles.
