Which commercial construction delivery model offers the best ROI for my project?
The best ROI typically comes from delivery models that involve the builder early—such as Construction Manager at-Risk (CMAR) or Design-Build (DB)—because both reduce change orders, compress schedules, and improve cost certainty compared to traditional Design-Bid-Build.
Why it matters
Return on investment in commercial construction is driven by cost control, schedule certainty, and risk reduction. Independent industry studies show that late decisions, siloed teams, and poor coordination add cost and months to project timelines. Owners evaluating delivery strategies can review core service approaches in the Conseco Group services overview.
Research from the Construction Industry Institute (CII) reports that rework can average around 5% of total project cost, which directly erodes contingency and Net Operating Income (NOI). You can review CII’s work at Construction Industry Institute.
Schedule certainty creates additional ROI. Interest carry on a $50 million project at a 7% annual rate can approach hundreds of thousands of dollars per quarter, and earlier openings bring forward rental income or operating revenue. In high-growth markets like Nashville and Middle Tennessee, this combination of reduced interest and accelerated revenue makes early builder involvement a strong strategic lever.
How it works
Design-Bid-Build (DBB) separates design and construction. According to the Design-Build Institute of America (DBIA), DBB projects tend to experience greater cost growth and more schedule delays than integrated delivery models. See DBIA’s data at DBIA.
Construction Manager at-Risk (CMAR) brings the builder in during design and typically ends with a Guaranteed Maximum Price (GMP). Early contractor involvement supports constructability reviews, real-time pricing, and phased strategies. CM/GC principles used by Conseco Group can be seen in examples throughout the project portfolio.
Design-Build (DB) unifies design and construction under one contract. DBIA research shows design-build consistently delivers faster schedules and less cost growth due to reduced interface risk and overlapping design and construction phases.
Integrated Project Delivery (IPD) uses shared risk/reward models and works best for complex, repeatable programs. It requires mature teams and strong governance to realize ROI.
What the data says
Industry research from DBIA, FMI, and CII consistently shows that CMAR and Design-Build outperform DBB in both cost and schedule reliability. DBIA performance studies, which can be found at DBIA, report 2–5 percentage points less cost growth and shorter overall durations compared to DBB.
CII research also shows rework commonly consumes around 5% of project value, and structured constructability programs can reduce that rework significantly. More detail can be found via the Construction Industry Institute.
To quantify ROI: a $50 million project at a 7% interest rate saving three months can see roughly $875,000 in lower interest carry. A 200,000-square-foot industrial project at $12/SF NNN opening 90 days early can generate about $600,000 in earlier rent—a combined benefit of approximately $1.48 million before soft-cost reductions.
Examples of accelerated delivery and performance outcomes can be reviewed in Conseco Group’s projects library.
Key considerations
Define ROI drivers early. Determine whether earliest revenue, lowest upfront cost, or risk transfer is the top priority. This decision drives contract selection, contingency strategy, and milestone structure.
Match delivery model to complexity. Healthcare, technical R&D, and complex commercial facilities often benefit most from CMAR or DB. Industrial and warehouse projects may favor DB for speed. Office and medical office with evolving requirements may benefit from CMAR’s early cost control.
Leverage local expertise. In Middle Tennessee, subcontractor capacity, permitting frameworks, and regional supply chain constraints strongly influence which model performs best. Teams with strong Nashville relationships and transparent cost platforms can lock pricing sooner and secure long-lead items earlier.
Demand measurable preconstruction. Target Value Design, risk registers, detailed cost modeling, and ROM-to-GMP tracking should all be included. Owners can request preconstruction deliverables and oversee progress through structured check-ins, with consultation options available through the contact page.
FAQs
How do I quantify schedule savings in ROI terms?
Calculate earlier rent or operating revenue, interest carry savings based on draw schedules, and avoided penalties. Subtract any preconstruction or delivery-model premiums to determine net ROI.
When is Design-Bid-Build still the right choice?
DBB works for simple scopes with complete documents and low schedule pressure. It is also used when procurement rules mandate competitive low-bid awards.
What’s the practical difference between CMAR and Design-Build?
CMAR keeps design and construction contracts separate but involves the builder early to set the GMP. Design-Build unifies design and construction under one contract and often accelerates delivery by streamlining decision-making.
How do early procurement and constructability reviews create value?
Early release packages protect the critical path, while constructability reviews reduce rework by catching design issues before field execution. CII research shows these practices significantly reduce schedule delays and cost growth.
What governance protects owners in CMAR or Design-Build?
Clear GMP exhibits, open-book accounting, third-party estimating, defined contingency rules, and structured milestone reviews ensure transparency and risk control throughout the project.
Conseco Group, a Nashville-based CM/GC founded in 1987, applies these practices across healthcare, office, and industrial projects.
