Pre-Construction Services

Make better decisions before they become expensive — pre-construction insight that protects budget, schedule, and long-term performance


In design-build and construction management delivery, Carl A. Nelson & Company becomes involved before design is complete—when decisions still have the greatest impact on cost, schedule, and long-term performance.

During pre-construction, our team works alongside owners and designers to evaluate options, identify risks, and align scope with budget. Addressing constructability, materials, and sequencing early helps prevent costly redesign, change orders, and schedule disruptions later in the project.

The earlier these conversations occur, the more value they deliver—allowing owners to make informed decisions while flexibility is still high and costs are easier to control.

Ability of Design-Builder or Construction Manager to Influence Project Cost



Our pre-construction services include:

  • Cost analysis — Review the design to confirm the project can be delivered within the available budget, with clear visibility into cost drivers and alternatives.
  • Constructability review — Evaluate drawings and specifications to identify potential conflicts, inefficiencies, or risks before they affect construction.
  • Pre-construction scheduling and fast-track planning — Identify opportunities to improve schedule performance, including coordination of long-lead materials and phased or early-start construction strategies when appropriate.
  • Bid package development and bid phase support — Assisting with scope definition, bid packaging, and coordination to promote clear pricing, strong bidder participation, and competitive, well-aligned bids.
  • Value engineering — Collaborate with the owner and design team to identify best-value alternatives that balance cost, schedule, durability, and long-term maintenance—without compromising performance or quality.

Additional pre-construction support includes Code Review, Building Information Modeling (BIM), and Design-Assist through Nelson Design, Inc., as well as early-stage planning services such as needs assessment and master planning .

In construction management, owners realize the greatest benefit by engaging Carl A. Nelson & Company early in the design process—or even before selecting a design consultant. Early construction input helps ensure initial concepts align with budget realities while preserving flexibility and quality.
