Quantity Takeoff Breakdown
A solid estimate begins with accurate takeoffs. Here’s what we uncovered in the drawings:
Hardscape & Concrete Works
| Item | Quantity | Description |
| Generator Pad | 40 SF | Reinforced concrete slab |
| Concrete Walkways | 383.1 SF | ADA-compliant pedestrian access |
| Access Ramps | 19.9 SF | Universal design compliance |
| Decorative Pavers | 67.9 SF | Enhancing aesthetics |
| Driveway Apron | 284.5 SF | Heavy-duty access for vehicles |
| Concrete Curbing | 318.4 LF | Edge definition, stormwater control |
| Flush Curb | 10.0 LF | ADA transition points |
| Drop Curb | 44.0 LF | Driveway vehicle access |
| Asphalt Paving | 6,922.8 SF | Main parking and travel lanes |
Key Takeaways That Tell the Real Story:
- ADA Compliance Isn’t Just a Checkbox – Meeting accessibility standards demands meticulous design and premium finishes, adding both complexity and cost.
- Curb Appeal with a Purpose – Robust curb systems aren’t just for looks; they’re the frontline in controlling stormwater flow and keeping traffic in check.
- Asphalt Speaks Volumes – A large paved area signals heavy public use, which means more wear, faster deterioration, and higher long-term maintenance costs.
Infrastructure & Traffic Control
Traffic management and user safety are integral in modern commercial builds. Here’s how it’s reflected in the scope:
Striping & Marking
| Feature | Quantity | Purpose |
| Standard Striping | 655 LF | Regular parking lines |
| Cross-Hatched Areas | 266.4 LF | Fire lanes / No Parking zones |
| Wheel Stops | 20 EA | Safety measure for vehicles |
| ADA Parking Symbols | 1 EA | Accessibility compliance |
Traffic & Security Features
| Element | Quantity | Purpose |
| EV Charger (Level 2) | 1 EA | Sustainability feature |
| Security Bollards | 38 EA | Pedestrian/vehicle protection |
| PVC Fencing (4’ High) | 85.7 LF | Site perimeter security |
| High Gate (3.5’ Wide) | 1 EA | Controlled access |
| Directional Signage | Multiple | Wayfinding system |
| Bike Rack Area | 1 EA | Sustainable transport support |
Estimator’s Tip
While they add a noticeable chunk to specialty infrastructure costs, skipping them could be far pricier in the long run. Without these safeguards, you’re opening the door to higher liability risks and expensive retrofits down the road. Sometimes, prevention isn’t just cheaper—it’s smarter.
Utilities & Drainage Systems
Sustainable drainage and efficient utility integration were major cost drivers. Here’s the scope:
Water & Sewer
| Item | Quantity | Description |
| Water Service Line | 31.3 LF | New municipal tie-in |
| Force Water Line | 31.4 LF | Pressurized flow system |
| Line Connections | 2 EA | Existing network connection points |
Stormwater Management
| Drainage Item | Quantity | Purpose |
| Roof Drains (6″ PVC) | 117.3 LF | Primary roof drainage system |
| UG Infiltration Basin | 1 EA | Sustainable water filtration |
| Catch Basins | 3 EA | Surface water collection |
| Type A Inlet | 1 EA | Connects system to storm sewer |
| Inlet Pipe | 24.4 LF | Pipe tie-in to catchment system |
Sustainability Takeaways
- Permeable pavers and underground infiltration systems may cost 10–15% more upfront, but they’re your insurance policy against costly stormwater fines or forced retrofits. It’s not just an upgrade—it’s future-proofing your site for decades to come.Utility tie-ins require municipal coordination—which can become time and cost intensive if not properly scheduled.
Risk & Complexity Factors
In 2025’s volatile construction market, ignoring risk is not an option (take a look at our risk management strategy). Key risk factors in this project included:
Major Cost Drivers
- ADA Compliance – Expect a 15–20% premium for the specialist design and high-end finishes needed to meet accessibility standards.
- Stormwater Systems – Highly regulated and technically demanding, these aren’t just install-and-forget—they require precision from day one.
- EV Infrastructure – From permits to electrical expertise, this is specialist territory that demands both time and budget.
Project Risks
- Soil Conditions – Uncertain subsurface strength can trigger costly rework if surprises arise mid-build.
- Underground Utilities – Hidden conflicts could mean major rerouting headaches—and big bills.
- Weather Delays – In some regions, the clock is ticking, with construction restricted to narrow seasonal windows.
Material Escalation – Post-pandemic supply chain swings keep prices unpredictable and budgets under pressure.
Modern Trends Captured in the Estimate
This estimate wasn’t just about today’s construction—it planned for the future. Trends reflected:
- Sustainability Integration: EV charging, bike racks, and water management systems
- Technology-Ready Sites: Electrical rough-ins and modular utility connections
- Green Construction Mindset: Permeable surfaces and reduced hardscape runoff
- Safety First: Bollards, traffic striping, and ADA pathways embedded from the start
Demolition Scope & Impact on Budget
Before Building, We Had to Break It Down – The site wasn’t a blank canvas. Extensive demolition of old hardscape, asphalt, and structural elements had to come first. This hidden phase packed a hefty price tag—one the original estimate didn’t fully capture. Sometimes, the real cost begins before the first brick is laid.
Demolition Quantity Takeoff
| Item | Quantity | Description |
| Existing Building Removal | 1,242.5 SF | Full structure demo |
| Paver Walkway Removal | 305.6 SF | Manual + light equipment removal |
| Concrete Planter Demolition | 48.7 SF | Light landscape work |
| Pavers with Landing Removal | 15.4 SF | Labor-intensive, detail work |
| Macadam Ramp & Driveway Removal | 7,572.3 SF | Major asphalt & road removal |
| Sidewalk Removal | 313.9 SF | Concrete cutting and disposal |
Impact on Cost
- The demolition phase turned out to be a major game-changer, adding unexpected complexity and extending the project scope far beyond initial expectations.
Removing the structural and hardscape elements wasn’t just a routine task—it demanded skilled craftsmanship, precise coordination, and meticulous planning for permits, debris removal, and on-site logistics.
Final Budget Analysis
Once demolition, utility scope, and specialty infrastructure were fully factored in, the estimation team revised the budget in five clear phases.
Note: This budget excludes the vertical building construction. The above numbers are for site development, utility work, paving, and infrastructure only.
Why the Estimate Increased from Initial Projection
The project’s budget trajectory shifted as unforeseen challenges emerged, prompting necessary adjustments to accommodate new complexities and evolving requirements.
Key Budget Increase Triggers
- Hidden Demolition Surprises – Early plans didn’t reveal the extra structures, ramps, and paving that had to be removed.
- Bigger Utility Demands – Gas, water, and electrical upgrades meant deeper trenching and tighter coordination on-site.
- High-End Site Enhancements – From EV chargers and security bollards to bike-friendly setups and stylish pavers, the scope leveled up.
- Market & Labor Shifts – 2025’s evolving construction market brought new realities for skilled labor and material sourcing.
