Greenfield Site Development Costs

Navigation: estimating-techniques | index

Site development is consistently underestimated on greenfield manufacturing projects. Estimators focused on the building and process often treat the site as an afterthought — and then discover that utilities are 800 feet from the property line, the site has 15 feet of relief requiring major earthwork, or a detention pond adds $400K to the civil scope. This page provides a systematic framework for estimating site development costs.

Typical range: Site development = 8–18% of TIC for a greenfield manufacturing site. On a $15M project, that’s $1.2M–$2.7M. It’s not a rounding error.

The Scope Categories

Every greenfield industrial site estimate should account for all of the following. Check each against the project before excluding:

Clearing and grubbing
Earthwork and grading
Utility services (off-site)
On-site utility distribution
Stormwater management
Paving and site concrete
Fire protection loop
Site lighting and signage
Fencing and gates
Landscaping
Railroad spur (if applicable)

1. Clearing and Grubbing

Removes vegetation, stumps, and organic material from the construction footprint and disturbed areas.

Site Condition	Unit Cost	Notes
Light brush / grass only	$1,000–$2,500/acre	Minimal equipment; mostly dozing
Light woodland (scattered trees)	$3,000–$6,000/acre	Includes stump removal; chipping or haul-off
Heavy woodland / dense trees	$6,000–$15,000/acre	More passes; larger equipment; may include grinding
Wetland mitigation required	Add $20,000–$100,000+	Separate permit; mitigation bank credit purchase

Estimating tip: The disturbed area is larger than the building footprint. Include the truck apron, parking, detention area, utilities corridor, and a construction laydown/staging zone. Budget disturbed area = building footprint × 2.5–4.0 for most industrial sites.

2. Earthwork and Grading

Moves soil to achieve design grades — cut from high spots, fill into low spots, and haul off or import as needed to balance the site.

This is the highest-variance scope item on the site. A 3-foot elevation change across a 5-acre site is $200K in earthwork. A 10-foot change could be $1M+. Always get a topographic survey and a conceptual grading plan before Class 3.

Item	Unit Cost	Notes
Cut (excavate in place)	$2–$5/CY	Backhoe + scraper; depends on soil type
Fill (import and compact)	$8–$20/CY	Import borrow cost varies widely by region
Haul off (excess cut to disposal)	$10–$25/CY	Tip fees vary; tipping distance matters
Subgrade compaction	$0.50–$1.50/SF	Proof-rolling + compaction testing
Structural fill under building	$4–$10/CY placed and compacted	If existing soil is unsuitable; quantity from geotech

How to estimate at Class 4/5 without topographic data:

Use a cut/fill balance assumption based on site description:

Flat site (< 2 ft relief): Earthwork budget $0.30–$0.80/SF of disturbed area
Gently rolling (2–5 ft relief): $0.80–$2.00/SF of disturbed area
Moderate relief (5–10 ft): $2.00–$4.00/SF of disturbed area; flag for topo survey ASAP
Significant relief (>10 ft): Do not estimate without a survey; risk too high

Document the assumption in the BOE and add geotech contingency.

3. Utility Services — Off-Site (From Street to Site)

Getting utilities to the property line is often the most surprising cost on a greenfield site. Distance from the street, existing infrastructure capacity, and utility company requirements all drive cost.

Utility	How Estimated	Typical Range
Electric service	Utility study required; cost = substation/transformer + service line from utility pole or underground	$50K–$500K+ for new manufacturing service (2,000A–4,000A); higher if requires new utility substation
Water main tap	Tap fee (utility-set) + service line + meter vault + backflow preventer	$20K–$150K depending on pipe size and distance
Sanitary sewer	Connection fee (utility-set) + service line to building + manhole	$15K–$100K; some municipalities require industrial pretreatment before connecting
Natural gas service	Utility sets the cost based on distance and volume; owner pays extension	$10K–$80K; higher if new gas main extension required
Telecom / fiber	Owner pays conduit installation only; carrier installs fiber	$5K–$30K for conduit run to the building

How to find these costs:

Call the local utility for each service. They provide preliminary service estimates at no cost and will tell you if the existing infrastructure can support your load.
Ask: “What is available at the property line?” and “What is the process and cost for connecting a new manufacturing facility drawing approximately [X] amps / [X] GPM / [X] MCF/hr?”

Key risk: Utility capacity constraints. If the nearest substation is at capacity, a new transformer or distribution upgrade may be required — at the owner’s cost. This can add $300K–$2M and 12–24 months of lead time. Always confirm utility capacity before signing a lease or purchase agreement on a greenfield site.

4. On-Site Utility Distribution

After utilities reach the property line, they must be distributed to the building.

System	Unit Cost	Notes
Sanitary sewer (8” PVC, gravity)	$30–$65/LF installed	Includes trench, pipe, backfill, manhole at connection
Domestic water (4”–6” ductile iron)	$25–$50/LF installed	Includes trench, pipe, backfill, valves
Natural gas (4” steel, medium pressure)	$20–$40/LF installed	Includes trench, pipe, cathodic protection
Electrical (underground primary)	$40–$100/LF for duct bank	Duct bank = conduit + concrete encasement; transformer pad extra
Telecom conduit (2” PVC)	$8–$18/LF	Pull wire only; carrier installs fiber
Storm sewer (15”–18” RCP)	$30–$55/LF installed	Includes trench, pipe, backfill, inlet structures
Inlets / manholes	$3,000–$8,000/EA	Precast concrete structures

Estimating on-site utilities from a site plan: Measure the LF of each utility run from the building to the property line (or on-site distribution main). Apply unit rates above, adjusted for depth (deeper = more expensive).

5. Stormwater Management

Every impervious surface (roof, paving, truck aprons) creates stormwater runoff that must be managed. Local regulations determine the requirement.

Open Detention Pond

Most common and least expensive solution for sites with adequate land area.

Item	Unit Cost
Earthwork (excavate pond)	$4–$8/CY excavated
Pond liner (if required)	$1.50–$4.00/SF of pond surface
Outlet control structure	$15,000–$40,000
Emergency spillway	$5,000–$20,000
Seeding and stabilization	$1,500–$4,000/acre
Total typical pond	$50,000–$400,000 depending on size and site

Pond sizing: local civil engineer determines based on local hydrology standards (100-year storm typically governs). As a rough guide: 1 acre-foot of storage per 3–5 impervious acres is a starting point.

Underground Detention (Tight Sites)

When land area is insufficient for a pond. Significantly more expensive.

Item	Unit Cost
Modular detention chambers (Cultec, StormTech)	$30–$60/CF of storage volume
Installation (excavation, geofabric, aggregate, backfill)	Add $15–$30/CF
Total installed	$45–$90/CF of storage

A 100,000 SF building with 1 acre-foot (43,560 CF) of required detention: 43,560 CF × $60/CF = $2.6M for underground detention. This is why tight urban sites are expensive.

Bioretention / Green Infrastructure

Some municipalities require or incentivize bioretention cells, bioswales, or permeable paving. Costs vary widely; budget with a civil engineer.

Industrial Stormwater Permit (NPDES)

For manufacturing facilities that handle chemicals, petroleum, or food processing waste, a Stormwater Pollution Prevention Plan (SWPPP) is required and the facility may need an NPDES multi-sector general permit.

Budget: $5,000–$25,000 for SWPPP preparation and permit filing. If ongoing monitoring is required, add $3,000–$8,000/year in operating cost (owner cost, not GMP).

6. Paving and Site Concrete

Item	Unit	Typical Cost	Notes
Truck apron (heavy-duty; 12” concrete)	SF	$10–$18/SF	Class A truck loads; 12” plain or reinforced concrete on compacted sub
Truck apron (heavy-duty; 6” asphalt over 8” base)	SF	$6–$10/SF	Lower first cost; higher maintenance; check owner preference
Automobile parking	SF	$3–$6/SF	4” asphalt over 6” base; standard commercial
Access road — light industrial	SF	$5–$9/SF	6” asphalt over 8” base
Access road — heavy industrial	SF	$8–$14/SF	8”+ asphalt; frequent heavy truck use
Concrete curb and gutter	LF	$28–$50/LF	Barrier or rollover curb
Concrete sidewalk (4”)	SF	$8–$15/SF	Standard pedestrian
Loading dock apron (12” concrete)	SF	$12–$22/SF	Designed for dock leveler loads + constant truck traffic
Concrete equipment pad (exterior)	SF	$18–$35/SF	Includes form, reinforcing, pour, finish
Striping and signage	LS	$5,000–$25,000	Parking + truck lanes + ADA

Truck apron design criteria: For Class A semi-trucks (65-foot wheelbase), the dock apron depth must be a minimum of 80–100 feet from the dock face. Shallow aprons are a common site plan error that forces expensive redesign during design development.

7. Fire Protection Underground Loop

A pressurized underground water loop around the perimeter of the building, separate from the building’s sprinkler system. Required by NFPA 13 and most AHJs for manufacturing occupancies above a certain square footage.

Item	Unit Cost
8” ductile iron pipe (fire loop)	$35–$65/LF installed
Fire hydrants	$5,000–$12,000/EA installed
Post indicator valves (PIV)	$2,500–$6,000/EA
Backflow preventer	$5,000–$15,000
Rule of thumb (complete loop)	$3–$8/SF of building footprint

Coordinate with the building sprinkler designer. The fire loop feeds the building sprinkler system. The fire loop designer and the sprinkler designer must agree on flow and pressure requirements before the loop is sized and priced.

8. Site Lighting and Signage

Item	Unit Cost
Pole-mounted light (30-ft pole, LED fixture, foundation, wire)	$5,000–$12,000/EA installed
Building-mounted lighting (LED shoebox, bracket)	$800–$2,500/EA
Dock area lighting (LED flood, high-mast)	$3,000–$8,000/EA
Monument sign (pre-fab; owner-designed)	$10,000–$50,000
Directional signs (interior road)	$500–$2,500/sign

Lighting coverage: 1 pole per 10,000–15,000 SF of paved area is a starting point for a manufacturing site.

9. Fencing and Gates

Item	Unit Cost
Chain-link (6 ft) with fabric	$18–$35/LF
Chain-link (8 ft) with barbed wire outrigger	$25–$45/LF
Ornamental steel fence (perimeter of office/entrance)	$40–$90/LF
Swing gate (single; chain-link)	$2,500–$6,000/EA
Slide gate (powered)	$8,000–$25,000/EA depending on width
Security guard booth	$15,000–$60,000

Note: Many F&B and CPG owners require FSMA-compliant perimeter security (controlled access to food production areas). This drives up gate and fencing spec.

10. Landscaping

Usually required by zoning as a condition of site plan approval. Confirm local requirements.

Item	Unit Cost
Seeding (turf grass)	$0.15–$0.40/SF
Sod	$0.60–$1.50/SF
Mulched planting beds	$1.50–$4.00/SF
Trees (2.5” caliper, installed)	$400–$900/EA
Irrigation system	$0.30–$0.80/SF of irrigated area

Budget placeholder if landscaping design is not yet available: $2–$6/SF of total landscaped area.

Industrial Park vs. Raw Land — Cost Comparison

Factor	Industrial Park (Shovel-Ready)	Raw Land
Utilities to lot line	Included in land price	Must be extended from street; $50K–$500K+
Site access road	Built by park	Owner builds or contributes
Stormwater management	Park-level system; shared pond or master permit	Full on-site system required
Permitting	Site plan approval often pre-approved by master plan	Full permitting from scratch
Site development cost	5–10% of TIC	12–20%+ of TIC
Timeline to construction start	3–6 months	9–24 months
Land premium	15–30% higher land cost	Lower land cost

The total cost difference is often smaller than it appears. The land savings on raw land are frequently consumed by longer permitting timelines (interest carry), extended utility costs, and higher site development contingency.

Geotech Risk — How to Handle It

What geotech affects:

Foundation type (spread footings vs. piles/caissons)
Structural fill depth and volume under the building
Pavement design (subgrade strength drives asphalt/concrete thickness)
Dewatering requirements (high water table)
Soil contamination (if Phase II shows petroleum or chemical contamination)

Standard assumption for Class 4/5 estimates (no geotech report):

“Estimate assumes soil bearing capacity of 2,000 PSF or better at 5 ft below design finished grade, no groundwater above 8 ft, and no contaminated soil within the project footprint. A geotechnical investigation is in progress. If soil conditions differ from these assumptions, foundation and earthwork costs will be adjusted by change order.”

If geotech shows poor soil:

Condition	Remediation Cost Premium
1,500 PSF bearing (marginal)	Engineered fill + over-excavation: $50K–$200K
<1,000 PSF bearing (poor)	Deep foundations (piles/caissons): $400K–$2M+ for a 100K SF building
High water table (< 5 ft)	Dewatering during construction: $50K–$300K; permanent underdrain may be required
Contaminated soil	Phase II environmental required before budgeting; cost is highly site-specific

Always include geotech as a PCSA deliverable — get it done before GMP commitment.

How to Estimate Site Development by Phase

Class 5 (No site plan, no topo, no geotech)

Use a total site development allowance as a % of building TIC:

Industrial park (utilities at lot line): 5–8% of building TIC
Raw land (no utilities at lot line): 12–18% of building TIC
Flag geotech as unknown; add $100K–$500K explicit geotech risk allowance

Class 4 (Conceptual site plan, topo survey, utility location confirmed)

Estimate each scope category using the unit costs above against measured quantities from the site plan. For utilities not yet sized, use the parametric ranges ($/LF × estimated run length).

Class 3 (Civil engineer engaged, preliminary site design complete)

Take off quantities from the 30–50% civil drawings. Get bids from 2–3 civil/site contractors. Add a 10–15% contingency for unforeseen conditions.

BOE Inclusions and Exclusions — Site Development

Always explicitly state in the BOE:

Whether utility service costs (off-site from street to property line) are included or excluded
The basis for earthwork estimate (topo survey used, assumed, or not available)
Geotech assumptions (bearing capacity, groundwater depth)
Whether stormwater management is included and the design basis
Whether railroad spur is included (if applicable)

Common exclusions:

Utility tap fees and connection fees (owner-side in many contracts)
Offsite road improvements required by the municipality
Environmental remediation (if contamination found)
Railroad crossing improvements (railroad authority jurisdiction)
