Most project owners encounter civil site development as a line item on a schedule (“site preparation: 6 months”) with almost no visibility into what actually happens during those months, the engineering decisions being made, or how those decisions affect the disciplines that follow. Then the geotechnical report comes back showing clay soils with a bearing capacity of 75 kPa, rather than the 150 kPa assumed in the preliminary design. The grading plan changes. The drainage design changes with it. The structural engineer is now redesigning foundations from spread footings to driven piles, a scope change that adds 8 to 12 weeks and six figures to the structural budget. And the root cause was a $40,000 to $80,000 geotechnical investigation that was deferred to “save money.”
This article breaks the site development process in civil engineering into its actual engineering phases. This is not a simplified checklist. It is a connected chain of decisions where each phase’s outputs become the next phase’s inputs. For each phase, you will see what happens, what deliverables the civil engineering team produces, and how each phase’s findings carry forward into downstream structural, process, and piping engineering. The goal: give you enough understanding of the civil site development workflow to set realistic schedules, ask better questions, and recognise when early investment prevents late-stage rework that drives most cost overruns on industrial capital projects.
Cost and timeline ranges in this article reflect typical experience across Canadian industrial projects. Actual figures vary by region, site conditions, and market timing.
For industrial and energy-sector capital projects, where civil engineering site preparation must coordinate with 5 to 8 engineering disciplines simultaneously, this understanding is essential. Vista Projects is an integrated engineering firm established in 1985, providing multi-discipline engineering services, including civil engineering, across 13 energy markets from offices in Calgary, Houston, and Muscat.
What Is Site Development in Civil Engineering?
Site development in civil engineering is the process of engineering raw or undeveloped land for construction readiness, encompassing site investigation, geotechnical analysis, grading and earthwork design, stormwater management, and subsurface utility infrastructure. For industrial projects, civil site development also includes coordination with structural, process, and piping engineering disciplines, which depend on civil outputs to begin their work.
The distinction matters because “site development” in residential or commercial contexts means something different: subdividing lots, installing municipal services, or preparing building pads for uniform floor loads of 2.4 to 4.8 kPa. In industrial civil engineering, the site development process transforms raw conditions into a construction-ready design package supporting equipment loads of 50 to 500+ kPa, accommodating process piping corridors, and providing data that multiple engineering disciplines depend on.
The process moves through seven phases: site survey, geotechnical investigation, environmental assessment, grading and earthwork design, stormwater and drainage design, subsurface utility design, and the civil-to-structural handoff. Each phase produces specific deliverables; each depends on data from the previous phase, and decisions made in the first two phases constrain what is possible and what it costs in every phase that follows.
Site Development Process Summary
The following table summarises durations, costs, and key dependencies for each phase of the civil engineering site development process. Ranges reflect variability across industrial project types, site conditions, and jurisdictions.
| Phase | Typical Duration | Typical Cost Range | Key Dependencies | Critical Output |

| 2. Geotechnical Investigation | 3 to 8 weeks | $40,000 to $150,000 | Survey data for borehole locations | Bearing capacity, groundwater depth, and foundation recommendations |
| 3. Environmental Assessment | 3 to 18 months | $5,000 to $100,000+ | Site access, regulatory jurisdiction | Phase I/II ESA, permit applications, constraints map |
| 4. Grading and Earthwork Design | 4 to 8 weeks | Included in the engineering fee | Geotechnical report, survey data | Finished grade elevations, cut/fill volumes |
| 5. Stormwater and Drainage Design | 4 to 8 weeks | Included in the engineering fee | Grading design, environmental permits | Detention sizing, discharge permits, containment design |
| 6. Subsurface Utility Design | 4 to 8 weeks | Included in the engineering fee | Grading design, process engineering input | Utility corridor layout, clash detection report |

| Total Engineering Timeline | 4 to 12 months | $60,000 to $400,000+ | Phases are interdependent | Construction-ready civil design package |
Note: Environmental permitting (Phase 3) often runs in parallel with other phases but can extend the overall timeline by 6 to 18 months, depending on jurisdiction and site conditions. Construction costs are separate from the engineering fees shown above.
Phase 1: Site Survey and Existing Conditions Assessment
Everything in the civil site development process starts with establishing the existing conditions on the ground. A civil engineering survey (topographic, boundary, and utility) establishes the spatial baseline of elevations, coordinates, and property limits against which all subsequent design is referenced.
A topographic survey captures ground elevations at 10 to 30 metre grid spacing, surface features, and visible infrastructure. A boundary survey confirms property limits, easements, and rights-of-way. A utility survey identifies underground services that must be protected, relocated, or connected. For sites with suspected underground infrastructure, subsurface utility engineering (SUE) using ground-penetrating radar adds $5,000 to $25,000 but prevents the far more expensive discovery of unmarked utilities during excavation.
The deliverables (topographic drawings at 0.25 to 0.5 metre contour intervals, an existing conditions report, and boundary documentation) directly determine whether the planned facility layout fits the site, where grading transitions occur, and how utilities route. If survey data is inaccurate by even 0.3 metres in a critical area, any downstream design will carry that error into grading elevations, pipe inverts, and foundation levels.
How much does a site survey cost for an industrial project?
Survey costs range from $15,000 to $75,000, depending on site area and complexity. Duration is 2 to 6 weeks. This is one of the shortest and least expensive phases, and one of the most consequential. Every experienced civil engineering team has seen a project where incomplete survey data required a grading redesign after earthwork began, a correction that cost 10 to 50 times the original survey shortfall. The survey feeds directly into Phase 2 (geotechnical) and Phase 4 (grading), making accuracy here the foundation for every civil engineering decision that follows.
Phase 2: Geotechnical Investigation
If the survey establishes what exists on the surface, geotechnical investigation reveals what lies underneath. It is the single highest-impact phase in the entire site development process. Geotechnical investigation analyses soil composition, bearing capacity (the maximum pressure soil can support without excessive settlement), and groundwater conditions to produce the data that every subsequent civil engineering decision depends on.
The investigation involves drilling boreholes 5 to 30 metres deep, spaced 30 to 75 metres apart; extracting soil samples; and conducting field and laboratory tests to determine soil classification, bearing capacity, groundwater elevation, settlement potential, and frost depth (which can reach 1.8 to 2.4 metres in northern Alberta). For industrial sites with equipment loads of 100-500+ kPa, geotechnical data determines whether deep foundations (piles driven to 10–25 metres) are required or spread footings, a decision that can increase the structural budget by $500,000-$2 million.
The dependency chain becomes concrete when the geotechnical report reveals groundwater at 1.5 metres instead of the 3.0 metres assumed, that single finding changes the allowable cut depth (dewatering adds $50,000 to $200,000), which changes the grading plan (less cut means more imported fill at $15–$40/m³), which changes drainage routing (different slope configurations), which changes stormwater detention sizing, which affects utility placement (inverts must clear groundwater), which constrains foundation locations. One data point. Six downstream design changes across four phases, plus structural engineering. This is why treating site development phases as independent steps misrepresents how the process works.
How much does a geotechnical investigation cost?
A mid-sized industrial site (5–20 hectares) costs $40,000 to $150,000 for 15-40 boreholes, laboratory testing, and an engineering report. That represents 0.1-0.3% of the total installed cost. A $75,000 geotechnical program that prevents a $750,000 foundation redesign is the best-returning investment in a project’s early phases.
The deliverables (a geotechnical report with boring logs, bearing capacity recommendations, groundwater assessment, and foundation type recommendations) are decision documents the owner uses to confirm or revise design assumptions before committing to detailed design.
Typical duration is 3 to 8 weeks. The most common scheduling mistake is deferring this work. Projects that skip geotechnical investigation uncover unfavourable conditions after grading design is 60–80% complete, forcing rework that costs 5-15 times the investigation cost.
Phase 3: Environmental and Regulatory Assessment
Environmental requirements govern what you can disturb, what you must protect, and what approvals you need before earthwork begins. This phase runs in part parallel to the geotechnical investigation, and the environmental permitting timeline is the longest single schedule constraint for 60 to 70% of industrial projects.
A Phase I ESA (records review and site inspection, $5,000–$15,000, 3–6 weeks) identifies contamination indicators, protected habitats, and watercourse setbacks. If contamination is found, Phase II ESA (sampling and lab analysis, $25,000–$100,000+) adds 6-12 weeks. Erosion and sediment control plans are prepared during this phase for regulatory approval before ground disturbance.
Permitting timelines vary dramatically. In Alberta, an EPEA approval through the Alberta Energy Regulator takes 3 to 12 months. Other jurisdictions range from 6 weeks to 18 months. This variability is why environmental assessment should start in the first month: the permitting timeline is outside the project team’s control, and late starts put the permit on the critical path with zero schedule float. Certifications and licensure requirements vary by jurisdiction. This article reflects Canadian standards and Alberta provincial regulations. For projects in other provinces or jurisdictions, verify requirements with the appropriate provincial authority having jurisdiction.
Environmental findings can restrict where development occurs, impose remediation obligations of $100,000 to $1 million or more, or add months to the schedule. Every month of avoidable permitting delay is a month of idle engineering capacity and deferred revenue. Environmental results also feed forward into Phase 5, where discharge permit requirements shape drainage design.
Phase 4: Site Grading and Earthwork Design
Grading is where the site takes its engineered shape, and where data from Phases 1 and 2 directly determines cost. Grading and earthwork design reshape natural topography to establish finished grade elevations (FGE), manage surface water flow, and create stable building pad areas.
The civil team calculates cut-and-fill volumes with the goal of balancing earthwork on-site. Importing structural fill costs $15–$ 40 per m³. A 10-hectare site needing 100,000 m³ faces $1.5 to $4 million in import costs. A grading design that achieves on-site balance eliminates that cost entirely. This is a design decision, not a construction inevitability, and the project owner should understand the implications before approving the grading plan.
The dependency on geotechnical data is direct: bearing capacity determines how much fill can be placed before the underlying soil settles excessively. Clay soils with high compressibility may require surcharging (pre-loading with extra material for 3 to 6 months), adding time and cost that must be planned, not discovered. If the geotechnical report was deferred, the grading design is built on assumptions, and assumptions in earthwork are expensive to correct once equipment is moving 5,000 to 20,000 m³ per week.
Grading design takes 4 to 8 weeks, but develops iteratively with drainage and utility design (Phases 5 and 6) because the three are interdependent. The team cycles through 2 to 4 iterations before reaching a coordinated solution. On a complex industrial site, this iterative cycle, not any single phase, determines the overall civil design timeline.
Phase 5: Stormwater and Drainage Design
Once grading establishes the site’s topography (Phase 4), stormwater and drainage design determines how water moves across and off the site. For industrial projects, this phase carries containment requirements absent from commercial development.
Stormwater systems (detention ponds, retention ponds, swales, culverts, and storm sewer networks) must handle both routine events (1-in-5-year storms) and extreme events (1-in-100-year, or 1-in-200-year for critical facilities). Detention ponds for a 10-hectare industrial site hold 5,000 to 25,000 m³, a significant land commitment that must factor into site layout from the earliest planning stages.
For industrial sites, runoff from process areas where hydrocarbons or chemicals could contact rainwater requires separate collection and treatment before discharge, in accordance with applicable provincial environmental regulations and CSA standards, including CSA Z767 for process safety management, where containment intersects with safety-critical systems. This containment requirement adds $200,000 to $1 million+ and directly affects grading (containment slopes of 1 to 2% with curbing) and utility design (separate storm and process networks that must not cross-connect). Generic site development guidance does not mention these requirements because they do not apply to commercial contexts.
Stormwater discharge permits are on the critical path alongside environmental permitting (Phase 3) in roughly 50% of industrial projects. Coordinating both from the outset prevents conflicting requirements.
Phase 6: Subsurface Utility and Infrastructure Design
Below finished grade, underground infrastructure (water, sewer, electrical conduit, fire water, communications, and process piping corridors) must be designed and coordinated before structural work begins. For industrial sites, this is substantially more complex than commercial work: below-grade process piping corridors, cable tray trenches, and instrument conduit all share subsurface space with conventional utilities.
At a mid-sized industrial facility, the civil team may coordinate 8 to 15 separate utility systems within a footprint where foundations, pipe-rack supports, and equipment pads compete for the same space. A utility trench routed through the footprint of a planned compressor foundation, a coordination failure costing $50,000 to $200,000 to resolve during construction, is entirely preventable during engineering if disciplines are communicating.
Why does integrated engineering matter most during utility design?
In a utility corridor layout, having civil, structural, piping, and electrical under one team yields the greatest reduction in design conflicts. Projects with fragmented contracts report 3 to 5 times more utility-to-foundation conflicts, because coordination through periodic document exchanges lags 2 to 4 weeks behind active design. This advantage carries directly into Phase 7, where utility locations are one of four critical data sets the structural team needs.
Phase 7: Civil-to-Structural Handoff and Site Readiness
This phase is rarely addressed in site development guidance, yet it causes the most expensive coordination failures on industrial projects. The civil-to-structural handoff is where site development outputs feed directly into structural and process engineering for foundation design.
Structural engineers need four data sets: bearing capacity recommendations (Phase 2), finished grade elevations at each pad location (Phase 4), drainage clearance requirements (Phase 5), and utility corridor locations (Phase 6). Missing or inaccurate data in any category requires a structural redesign, which, on an industrial project, cascades through mechanical, piping, electrical, and instrumentation engineering. A single foundation redesign that triggers piping rerouting and conduit relocation typically costs $100,000 to $500,000 in engineering rework alone.
When civil, structural, process, and piping operate under one team, sharing a project model and reviewing coordination weekly, the foundation design interface is managed continuously rather than discovered as conflicts at handoff. Engineering services for industrial site development are delivered under the oversight of appropriate regulatory bodies, including APEGA in Alberta and equivalent provincial regulators where applicable.
Where Do Site Development Delays Originate?
The pattern is consistent: civil site development delays come from missing or late information, not slow execution. Four sources account for the majority of schedule overruns.
First, deferred geotechnical investigation. Designing to assumed soil conditions and then discovering reality forces 30 to 60% of civil design to be reworked, adding 6 to 16 weeks. Second, late environmental permitting. Regulatory review cycles of 3 to 12 months cannot be compressed. Third, scope changes after grading design is underway, triggered by late input from process or structural engineering. Fourth, coordination failures where design conflicts are discovered during construction rather than engineering, when changes cost 4 to 10 times more.
Every one of these is an information problem, not an execution problem. Projects that invest in geotechnical investigation before finalising the schedule, engage environmental permitting in the first month, and coordinate civil with structural and process engineering from grading onward, eliminate the most predictable sources of rework. That distinction matters when every month of delay has a quantifiable cost in deferred revenue.
Frequently Asked Questions
How long does civil site development take for an industrial project?
Civil site development engineering takes 4 to 12 months, excluding construction. The primary variables: site size and terrain complexity, geotechnical conditions (unfavourable soils add 2–4 months), environmental permitting (6 weeks to 18 months depending on jurisdiction), and the number of coordinating disciplines. Smaller projects with favourable conditions are completed in 4 to 6 months. Large or complex sites should plan for 8 to 12 months.
What deliverables does a civil engineering team produce?
The civil team produces survey drawings and existing conditions reports (Phase 1), geotechnical reports with bearing capacity recommendations (Phase 2), environmental assessments and permit applications (Phase 3), grading plans with earthwork quantities (Phase 4), stormwater management reports (Phase 5), utility layout plans with clash detection reports (Phase 6), and the civil design package for structural handoff (Phase 7). Each deliverable serves as a decision point. The geotechnical report determines the foundation approach, the earthwork quantities determine the largest civil construction cost, and the civil design package enables downstream disciplines to begin without rework.
When should other disciplines get involved in site development?
Structural and process engineering should engage during geotechnical investigation and grading design, not after the civil design is complete. Sequential handoff is the primary cause of foundation conflicts on industrial projects. When structural engineers review geotechnical data during Phase 2 and confirm pad elevations during Phase 4, conflicts that cost $5,000 to fix in engineering are caught before they become six-figure corrections during construction. Integrated engineering teams manage this as a continuous process. Separate contracts require the owner to enforce cross-discipline reviews every 1 to 2 weeks during active civil design.
How much does site development cost for an industrial project?
Civil site development engineering costs range from $60,000 to $400,000+, depending on site size, complexity, and the extent of required environmental investigation. This covers only the engineering design phases. Construction costs are separate and typically range from $500,000 to $5 million or more for a mid-size industrial site, driven primarily by earthwork volumes, utility scope, and whether soil must be imported or exported. The engineering investment represents 2-5% of the total site development cost. Based on industry experience, projects that underspend on engineering (particularly geotechnical investigation) routinely overspend on construction by 15 to 30%. For a complete breakdown, see our guide to site development costs.
What is the difference between site development and land development?
Site development and land development overlap but serve different purposes. Land development is a real estate term covering the entitlement, subdivision, and infrastructure installation that converts raw land into buildable lots for sale or lease. Site development is an engineering term covering the technical process of preparing a specific parcel for construction. On industrial projects, site development refers specifically to the civil engineering scope: survey, geotechnical investigation, grading, drainage, and utilities. Land development may or may not be involved, depending on whether the owner already controls an entitled parcel. The two processes share many of the same engineering activities, but land development includes additional legal, regulatory, and commercial steps outside the civil engineering scope.
What happens if geotechnical conditions are worse than expected?
When geotechnical investigation reveals unfavourable conditions (low bearing capacity, high groundwater, contamination, or expansive soils), the project team has several options depending on the severity. Minor issues like moderately low bearing capacity may require thicker granular pads or slightly deeper footings, adding 5 to 15% to foundation costs. Moderate issues like high groundwater may require dewatering systems during construction ($50,000 to $200,000) or redesigning the grading plan to reduce cut depths. Severe issues like very low bearing capacity or contamination may require deep foundations (adding $500,000 to $2 million), soil remediation ($100,000 to $1 million+), or, in extreme cases, reconsidering the site entirely. The critical point: discovering these conditions during geotechnical investigation costs a fraction of discovering them during construction.
Can site development phases overlap to compress the schedule?
Some phases can overlap, but the dependency chain limits how much compression is possible. Survey and geotechnical investigation can start simultaneously. Environmental assessment typically runs in parallel with other early phases. However, grading design cannot begin until geotechnical data is available. Stormwater design cannot be finalised until grading is established. Utility design requires both grading and input from process engineering. The civil-to-structural handoff requires all civil phases to be substantially complete. Projects that attempt to overlap dependent phases end up with rework that exceeds any time savings. The most effective schedule compression comes from starting early (particularly environmental permitting) and running independent activities concurrently, not from overlapping dependent phases.
How do I choose a civil engineering firm for site development?
Selecting the right civil engineering firm for industrial site development requires evaluating experience in your specific project type, familiarity with the local regulatory environment, and integration capability with other engineering disciplines. Key questions: Has the firm completed similar industrial projects in the same jurisdiction? Can they demonstrate coordination experience with structural, process, and piping disciplines? Do they have in-house geotechnical capability or established relationships with geotechnical consultants? What is their approach to the civil-to-structural handoff? For industrial projects, the coordination capability matters as much as the civil engineering capability. A firm that produces excellent civil drawings but cannot integrate with other disciplines will create handoff problems that cost more than any savings on the civil scope.
Making Site Development Work for Your Project
Civil site development for industrial projects is a chain of engineering decisions, not a checklist of independent steps. Geotechnical findings determine grading. Grading determines drainage. Drainage and grading together determine utility routing. And every civil output feeds into the structural and process engineering that follows. Project owners who understand these dependencies set realistic schedules, invest in early geotechnical work that returns many times its cost through avoided rework, and prevent the coordination failures behind most site development overruns.
Three actions for the first 30 days of a capital project: commission a geotechnical investigation before locking the schedule, engage environmental permitting as early as your jurisdiction allows, and confirm that civil engineering will coordinate with structural and process engineering from grading onward rather than be handed off as a completed package.
Vista Projects provides civil engineering as part of an integrated multi-discipline approach, coordinating site development with structural, process, piping, and electrical engineering under one team.
