Construction Cost Estimating
Our certified estimators deliver precise cost projections using current market data and proprietary analysis methods. We support design teams and contractors through all project phases, maintaining accuracy within 2-3% of final bids. Our services include conceptual planning, design completion analysis, and bid climate evaluation to ensure realistic budget forecasting.
Project Controls
We provide comprehensive cost and schedule oversight using industry-leading software tools. Our controls framework includes budget management, contingency planning, and real-time progress tracking. By scaling solutions to client needs, we ensure financial transparency and risk mitigation for both small projects and multi-billion-dollar infrastructure programs.
Scheduling
Utilizing Primavera P6 and Microsoft Project, we develop detailed construction schedules with integrated milestone tracking. Our process includes baseline schedule creation, progress monitoring, and exception reporting to identify delays. We implement corrective actions and schedule workarounds to maintain project timelines while accommodating necessary changes.
Contract Management
We manage contract lifecycle processes from bid evaluation to post-award implementation. Our services include terms negotiation, compliance monitoring, and payment processing. By documenting changes and ensuring stakeholder alignment, we minimize disputes and maintain contractual obligations throughout project execution.
Constructability Reviews
Our team evaluates design documents for practical construction feasibility, identifying potential conflicts and inefficiencies. Through phased analysis, we recommend cost-saving modifications and schedule optimizations. This proactive approach reduces change orders, improves safety, and ensures environmental compliance during project execution.
