IMP install teamWhat "fast response" actually means here.
Most commercial GCs take 2 to 4 weeks to bid. TCG's lean structure and AI-powered estimating tools compress that meaningfully. Here are the real numbers:
Automated Good / Better / Best budget tiers. 24/7. No human required.
Inquiries submitted Mon-Fri during business hours typically reach a partner inbox within four hours.
Weekend and after-hours inquiries are answered by 10 AM Mountain Time the next business day.
For design-build pursuits with conceptual drawings, expect a written ROM budget within one business week.
Hard-bid pricing against complete construction documents. Faster than the 2 to 4 week industry norm for most $1M-$10M scopes.
If you're a GC asking whether TCG's IMP crew is available for a specific date and region, you'll get a yes/no the same day.
What to include for the fastest, most useful first response.
None of these are required, but each one cuts a round of back-and-forth and sharpens the first response.

- Facility type: warehouse, cold storage, cannabis, food processing, data center, retail, medical, hospitality, etc.
- Approximate square footage: even a range helps
- Target start date: or "fastest possible"
- Budget range: if known; helps frame design recommendations
- Delivery method: design-build, design-bid-build, CMAR, GMP
- Drawings or site plan: attach if available; not required
- Capital status: equity in place, lender selected, or still raising
- Any specialty scope: IMP, polyaspartic flooring, FM-rated panels, USDA compliance, cleanroom, cold storage zones
- Inquiry type: owner / developer / GC needing sub / architect / broker / referral partner

Fast answers before you reach out
What is the fastest way to get a commercial construction estimate from Terrapin Construction Group?
The fastest path is the TCG.ai instant estimator, which returns Good, Better, and Best budget tiers in under two minutes for most commercial project types. For IMP supply and install pricing, use the IMP-specific estimator. For complex or larger scopes ($5M and up), submit the contact form on this page and a partner will respond within one business day.
What is Terrapin Construction Group's typical response time to inquiries?
Inquiries submitted Monday through Friday during business hours typically receive a response within four hours. Weekend and after-hours submissions are returned by 10 AM Mountain Time the next business day. AI-generated estimates from TCG.ai return in under two minutes regardless of time of day.
Where is Terrapin Construction Group located and where do you work?
TCG is headquartered in Denver, Colorado with corporate registration in Sheridan, Wyoming. The firm is licensed in all 50 states and has executed projects across 38 states for IMP installation alone. Active markets include Denver, Houston, Atlanta, Chicago, Phoenix, Dallas, Charlotte, Nashville, Tampa, Salt Lake City, Minneapolis, and 40 other major US metros.
What information should I include in my project inquiry?
To get the fastest, most useful first response, include: project location (city and state), facility type (warehouse, cold storage, cannabis, food processing, data center, retail, medical, etc.), approximate square footage, target start date, budget range if known, and the delivery method you are considering (design-build, design-bid-build, CMAR). Drawings or a site plan accelerate the process but are not required for an initial conversation.
Do you offer free consultations or preliminary budgets?
Yes. Initial 30-minute consultations are free. Preliminary budgets generated through the TCG.ai instant estimator are free. For deeper preconstruction services including value engineering, detailed estimates against drawings, scheduling, and feasibility analysis, TCG offers paid preconstruction packages starting at $2,500 with credit applied toward a signed construction contract.
Do you work with developers, owners, GCs needing IMP subcontractors, and architects?
Yes. TCG works in four primary capacities: (1) full design-build GC for owners and developers, (2) IMP installation subcontractor for other commercial GCs nationwide, (3) preconstruction and owner's rep services for complex builds, and (4) referral partner for architects and brokers who need a qualified GC for client projects. The contact form on this page routes to the right partner based on inquiry type.
What project sizes does Terrapin Construction Group take on?
TCG's core project range is $1M to $30M. The firm has executed IMP installation scopes up to $8M as a subcontractor and full design-build commercial projects up to $25M. Smaller tenant improvement and IMP-only scopes starting around $250K are evaluated based on geographic fit and crew availability.
What is the difference between the AI estimator and the project inquiry form?
The TCG.ai estimator is for fast, automated budget tiers based on project type, size, and region. It is ideal for early feasibility, lender conversations, and ballpark pro forma inputs. The project inquiry form on this page reaches the partners directly and is the right path for confirmed projects, RFPs, design-build engagements, and questions that require human expertise. Both are free.
Can I send drawings, specs, or RFP documents through the contact form?
Yes. The form accepts file attachments. For larger files or full document sets, mention it in your message and a partner will send a secure upload link in the response email. TCG holds all owner and developer documentation in confidence and signs NDAs on request before reviewing proprietary plans.
