Concept Layout – Carpark Redesign (Smithfield)
Modernizing urban infrastructure demands a rigorous balance of spatial efficiency, traffic kinematics, and community aesthetics. Contracted by EPTEC, KEVOS® executed a data-driven concept redesign for the Smithfield carpark. Faced with severe footprint constraints and growing community demand, our civil engineering team developed a multi-level structural proposal that successfully increased vehicle capacity by 20%, integrated sustainable stormwater management systems, and laid the foundation for future-ready smart-parking technologies.
Executive Summary
project profile & parametersUrban parking facilities frequently suffer from legacy design flaws—manifesting as severe traffic bottlenecks, high pedestrian risk, and inefficient spatial utilization. The Smithfield carpark redesign required a holistic civil engineering approach to maximize utility within a restricted site boundary. KEVOS® conducted extensive traffic flow analyses and user-feedback audits to identify core circulation pain points. The resulting design proposal transitioned the site from a congested single-level lot into a structurally optimized multi-level parking environment. By enforcing a one-way traffic flow, isolating pedestrian pathways, and integrating permeable paving, the concept delivered a scalable, sustainable asset that aligns with modern community expectations and municipal regulations.
Adding parking bays without optimizing the entry and exit kinematics creates gridlock. Structural capacity must always scale proportionally with active traffic flow efficiency.
- Analyze real-world traffic data to eliminate circulation bottlenecks.
- Maximize vertical space via multi-level structural steel and concrete framing.
- Incorporate smart-sensor layouts to reduce idle vehicle emissions.

Core Concepts
civil infrastructure glossaryMulti-Level Structure
Designing elevated parking decks using structural steel or reinforced concrete to multiply vehicle capacity without expanding the ground footprint.
One-Way Circulation
Engineering traffic flow paths that move in a single, continuous loop to eliminate head-to-head bottlenecks and reduce minor collisions.
Pedestrian Isolation
Creating raised or physically guarded walking paths that safely separate foot traffic from active vehicle reversing zones.
Permeable Paving

Heat Island Effect
The tendency of massive concrete lots to absorb and radiate heat. Mitigated by integrating native tree canopies and soft landscaping.
Traffic & Movement Analysis
The mathematical study of peak vehicle entry/exit rates to appropriately size ramp widths and ticket boom gates.
Stakeholder Alignment
Coordinating the structural layout directly with local councils to ensure designs meet municipal town planning goals.

urban planning integrationsDependencies & Interactions
infrastructure system boundariesTotal bay capacity depends on vertical structural design — small land footprints require multi-level engineering to achieve the 20% capacity target.
Traffic efficiency depends on one-way routing — eliminating two-way blind corners prevents gridlock during peak morning and afternoon hours.
Stormwater management depends on permeable materials — porous paving absorbs heavy rain, preventing the municipal drains from overflowing.
User safety depends on dedicated path layouts — physically separating pedestrians from reversing cars drops accident rates to near zero.
Council approval depends on stakeholder collaboration — ensuring the design meets local town planning rules prevents costly proposal rejections.
Parking speed depends on smart tech integration — active digital signs guide drivers instantly to open spots, reducing frustration.
Key Takeaways
essential project lessons- Flow limits dictate capacity — a carpark with 1,000 spots is useless if the entry ramps cause gridlock; optimize movement first.
- Build vertically on tight sites — when the land footprint is restricted, multi-level structural decks are the only way to scale capacity.
- Separate people from cars — clearly defined, isolated pedestrian paths are non-negotiable for modern public safety.
- Let data drive the design — traffic analysis and user surveys reveal the true operational bottlenecks of legacy sites.
- Use green tech for water control — permeable paving is a cost-effective way to manage stormwater without massive underground pipes.
- Trees cool down concrete — adding native landscaping breaks up "heat islands" and makes the facility visually welcoming.
- Smart parking reduces emissions — guiding drivers directly to spots with sensors cuts down idle driving and localized pollution.
- Collaborate with councils early — aligning designs with municipal expectations ensures smooth sailing during the approval phase.

Frequently Asked Questions
clarifying the design choicesWhy is a one-way circulation system better than two-way?
Two-way systems require wider lanes and create dangerous blind spots when cars reverse. One-way loops narrow the required lane width (saving space for more parking bays) and eliminate head-to-head traffic conflicts.
How does permeable paving help the environment?
Traditional asphalt forces all rainwater into the city's storm drains, often causing floods. Permeable paving has tiny holes that let water soak naturally into the ground below, reducing the burden on municipal infrastructure.
What makes the proposed carpark "smart"?
The design incorporates layout wiring for ceiling-mounted sensors over each bay. These sensors link to digital signs at the entrance, telling drivers exactly which floor and aisle has open spaces before they even enter.
How did budget constraints influence the multi-level design?
Instead of proposing expensive underground excavation, we opted for an above-ground multi-level structure using standardized, durable materials. This balances long-term longevity with immediate cost-effectiveness.
Why isolate pedestrian paths entirely?
In busy carparks, the greatest risk is a reversing vehicle hitting a person walking behind them. By creating dedicated, raised, or fenced walkways, pedestrians can reach the exits without walking down active vehicle lanes.
What was the purpose of user feedback in this engineering project?
Data can only show so much. Surveying frequent users revealed hidden pain points—like specific times of day when exits jammed—allowing us to tailor the geometric layout to solve actual daily problems.
