At Terrapin Construction Group (TCG), we believe successful projects begin long before the first shovel hits the ground. Our preconstruction services provide owners with clarity, confidence, and control by addressing budget, design, schedule, and risk from the very start. With over one million square feet of projects delivered nationwide across 38 states, our team has the experience to guide owners, developers, and operators through the complexities of commercial construction with transparency and precision.

Analyzing Your Project
Our AI engine is reviewing current market data, CSI divisions, and regional labor rates…
This estimate is preliminary and generated by AI using historical cost data and regional market indices. All quantities and pricing will be verified by a TCG estimator before any formal proposal. Contact TCG for a formal proposal.
Cost Opinions – Accuracy at Every Design Milestone
TCG delivers progressive cost opinions tied directly to design development. Each estimate evolves with design detail, giving owners and lenders confidence as scope and systems are defined:
Schematic Design (SD)Conceptual estimate within ±20% accuracy based on program requirements.
Design Development (DD)Refined estimate within ±15% accuracy with major systems identified.
85% Construction Documents (CD)Detailed estimate within ±10% accuracy supported by subcontractor budgets and vendor pricing.
100% Construction DocumentsA fully buyout-ready construction budget, typically within 3 weeks, including subcontractor proposals and material quotes.
Estimates are presented in CSI division format, ensuring clarity across all building systems.
Division Breakdown
Our cost opinions include all major divisions, such as:
Divisions 21–28 – Fire Protection, Plumbing, HVAC, Electrical, Security, IT
Construction Cost Deliverables
Our deliverables include a detailed breakout of hard construction costs by major category, with line items for general conditions, contingency, bonds, insurance, and contractor fee. TCG structures budgets to support both Guaranteed Maximum Price (GMP) and Cost-Plus contracts — allowing us to align contract models with your financing strategy, risk profile, and project goals.

Owner-Provided Equipment & Systems
Many projects include owner-furnished items such as specialized equipment, IT infrastructure, or furnishings. While owners may procure directly, TCG's procurement strength and vendor relationships often result in better-than-direct pricing on items like HVAC equipment, insulated metal panels, and specialty systems. We can either install owner-furnished items or manage procurement end-to-end, reducing risk and maximizing value.
Soft Cost Management
Our preconstruction team also tracks and manages soft costs, ensuring total visibility into all project expenses. Typical soft costs include:
FF&E CoordinationFurniture, fixtures, and equipment planning and procurement coordination.
Total Project Cost – The Full Picture
We provide owners and lenders with a comprehensive roll-up of all costs: hard construction, owner-provided equipment, and soft costs. Budgets clearly highlight controllable vs. uncontrollable costs, escalation risks, and scope allowances — eliminating surprises during construction and enabling reliable capital planning.
Assumptions & Clarifications
Every cost opinion includes clear assumptions on scope, escalation factors, site conditions, and utility availability. These clarifications define accuracy, highlight risks, and ensure all stakeholders share a common baseline.
Value Engineering Options
We take a proactive, impartial approach to Value Engineering (VE). Our recommendations are vendor-agnostic and supported by cost-benefit analysis, giving owners clarity on the cost, schedule, and performance impact of each option. Examples include:
Alternative Wall AssembliesEvaluating IMP, tilt-up, CMU, and hybrid envelope systems for optimal cost and performance.
HVAC System Right-SizingMatching mechanical systems to actual load requirements to reduce capital and operating costs.
Lighting SubstitutionsLED and controls upgrades that reduce cost while meeting energy code compliance.
Modular vs. ConventionalComparing prefabricated and modular approaches including pre-engineered metal buildings for schedule and cost advantages.
Schedule Development
As design advances, TCG develops increasingly detailed project schedules:
1
Early Milestone SchedulesPermitting, design, procurement, and construction durations.
2
Critical Path SchedulesGantt charts tracking long-lead items such as switchgear, structural steel, HVAC equipment, or specialty finishes.
This ensures transparency, predictability, and accountability throughout preconstruction.
Owner's Advocacy
By engaging TCG for preconstruction, owners gain more than estimating and scheduling — they gain a trusted partner and advocate. Our leadership team acts as an extension of ownership, providing oversight, vendor coordination, and strategic guidance to protect budget, schedule, and operational goals at every step. Whether your project requires general contracting, design-build, or construction management, TCG's preconstruction foundation sets the stage for success.

Frequently Asked Questions
Still have questions? Take a look at the FAQ or reach out anytime. If you want to chat with the TCG Team about your project, go ahead and schedule a meeting with us now.
Preconstruction covers project programming, cost estimating, schedule development, value engineering, constructability reviews, and early procurement planning — all before construction begins.
Preconstruction identifies and resolves cost, design, and schedule risks before they become expensive change orders — it is the phase most responsible for keeping projects on budget.
Preconstruction fees vary by project complexity. In many cases, preconstruction costs are credited back against the construction contract when TCG is awarded the full build.
You can schedule an intro call directly via the Calendly link on the TCG website, use the TCG.ai free estimator, or email info@terrapincg.com to request a competitive project bid.
