IMP install team

What "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:

< 2 min AI estimate turnaround

Automated Good / Better / Best budget tiers. 24/7. No human required.

< 4 hrs Form reply (business hours)

Inquiries submitted Mon-Fri during business hours typically reach a partner inbox within four hours.

10 AM MT Off-hours catch-up

Weekend and after-hours inquiries are answered by 10 AM Mountain Time the next business day.

3 to 5 days Preliminary budget against drawings

For design-build pursuits with conceptual drawings, expect a written ROM budget within one business week.

7 to 14 days Full hard bid against CDs

Hard-bid pricing against complete construction documents. Faster than the 2-4 week industry norm for most $1M-$10M scopes.

Same day IMP install scheduling check

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.

  • Project location: city and state at minimum
  • 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

Contact and response FAQ.

Direct answers / no buried fine print

What is the fastest way to get a commercial construction estimate from TCG?
The fastest path is the TCG.ai instant estimator at terrapincg.com/instant-estimator-ai-1 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 at terrapincg.com/impinstall-estimator. For complex or larger scopes ($5M and up), submit the form on this page and a partner will respond within one business day.
What is the 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 TCG located and where do you actually work?
Headquartered in Denver, Colorado with corporate registration in Sheridan, Wyoming. Licensed in all 50 states. IMP installation has been delivered in 38 states across 1M+ SF over 10 years. Active full-service GC markets include Denver, Houston, Atlanta, Chicago, Phoenix, Dallas, Charlotte, Nashville, Tampa, Salt Lake City, Minneapolis, and 40+ other US metros. The full city list is at the bottom of this page.
What information should I include in my project inquiry?
Project location (city and state), facility type, approximate square footage, target start date, budget range if known, delivery method you're considering (design-build, DBB, CMAR), and inquiry type (owner, developer, GC needing IMP sub, architect, broker, referral partner). Drawings accelerate 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 through the TCG.ai estimator are free. For deeper preconstruction including value engineering, detailed estimates against drawings, scheduling, and feasibility analysis, paid preconstruction packages start at $2,500 with credit applied toward a signed construction contract.
Do you work with developers, owners, GCs needing IMP subcontractors, architects, and brokers?
Yes. TCG works in five primary capacities: full design-build GC for owners and developers, IMP installation subcontractor for other commercial GCs nationwide, preconstruction and owner's rep for complex builds, design partnership with architects and engineers, and pre-acquisition feasibility review for brokers and capital partners. The form below routes by inquiry type so the right partner replies first.
What project sizes does TCG take on?
Core range is $1M to $30M. IMP installation scopes have run up to $8M as a subcontractor and full design-build commercial projects up to $25M. Smaller TI and IMP-only scopes starting around $250K are evaluated based on geographic fit and crew availability.
Can I send drawings, specs, or RFP documents through the 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 owner and developer documentation in confidence and signs NDAs on request before reviewing proprietary plans.
What's the difference between the AI estimator and the inquiry form?
The AI estimator is automated and instant - ideal for early feasibility, lender conversations, and pro forma inputs. The form reaches the partners directly and is the right path for confirmed projects, RFPs, and questions that require human judgment. Both are free. Most owners use the estimator first and then submit the form once they're ready for a conversation.
What changed on this contact page in May 2026?
The page was rebuilt to clarify the three contact paths (AI estimator, project form, IMP team), publish actual response time commitments, route inquiries by type, and link the four pillar reference hubs and recently refreshed cost articles. The Squarespace form was preserved unchanged so existing inbox routing and notifications continue to function.
