Our Projects
If you would like to take a closer look at what we have accomplished and how we approach our projects, you can explore the projects we have completed and those currently under development. This overview will help you better understand the depth of our engineering expertise, our innovative solutions to complex challenges, and the effective collaboration model we have built with our partners.
Dam Body Design
The dam body is the most critical structure of the project. Its type, geometry, and zoning are determined based on the dam’s purpose, ground conditions, topography, and availability of local construction materials.
- Type Selection: We compare gravity, arch, buttress, earthfill, rockfill, or composite systems considering topography, geological conditions, material availability, cost analysis, and seismic criteria to determine the most suitable dam type.
- Geometric Design: We design key elements such as dam height, crest width, upstream and downstream slopes, core and filter zones using detailed engineering analyses.
- Stability Analyses: We perform sliding, overturning, settlement, stress, seepage, and seismic analyses using numerical modeling and Finite Element Method (FEM) for advanced evaluations.
Spillway Design
We design spillways—critical for ensuring dam safety during floods—with high precision in both hydraulic and structural aspects.
- Diameter and Hydraulic Capacity Calculations: We size bottom outlets based on sediment discharge needs, desired release duration, and hydraulic performance.
- Inlet and Outlet Structures: We optimize structures to enable efficient sediment flushing and safe downstream water conveyance.
- Control Components: We determine valve selection, layout, and operational scenarios through technical and hydraulic analyses.
Bottom Outlet Design
We design bottom outlet structures in detail to ensure sediment discharge from the dam reservoir and to control operational water levels.
- Spillway Type Selection: We design free-flow, controlled, side-channel, siphon, or chute-type spillways based on flood discharge, terrain features, and dam type.
- Hydraulic Design: We optimize crest length, water levels, approach and exit channels, and energy dissipating structures using design flood discharges as key parameters.
- Structural Calculations: We perform strength and stability analyses for reinforced concrete components, ensuring long-term durability and safe operation.
Diversion Design
We design diversion systems to redirect river flow away from the construction site during dam construction in a controlled manner.
- Type and Capacity Selection: Tunnel, open channel, or pipeline systems are selected based on construction duration and design flood discharges.
- Cofferdam and Inlet/Outlet Structures: We design temporary structures to keep the construction site dry, supported by stability analyses.
Clash Prevention with 3D BIM Modeling
One of the biggest challenges in today’s infrastructure projects is the conflict between underground utility systems, often discovered only during construction, leading to costly delays. Noktasal Project integrates advanced Building Information Modeling (BIM) techniques into infrastructure projects to eliminate these risks during the design phase.
Implementation Capabilities:- All underground utility components (stormwater, wastewater, potable water, electricity, telecommunications, etc.) are modeled in a 3D digital environment.
- Each network is visualized in accordance with real terrain conditions, considering elevation levels, cross-sectional details, pipe diameters, and slopes.
- Horizontal and vertical clearance checks are performed between modeled systems. Potential conflicts are detected early and resolved during the design process.
- All infrastructure systems are aligned using a shared coordinate system, ensuring seamless collaboration among multidisciplinary engineering teams.
- The digital models are tested in virtual environments before construction, enabling preemptive resolution of potential issues.
- The final model can be shared with project stakeholders for visualization and analysis, accelerating decision-making processes.
- Minimizes the need for changes during excavation and construction phases.
- Reduces material waste and rework.
- Eliminates uncertainties in field execution, shortening the overall project timeline.
- Ensures clear, visual, and accurate information flow to field teams.
- This holistic approach allows Noktasal Project to guarantee quality and efficiency in infrastructure investments through accurate upfront planning and coordination.
Wastewater and Sewerage
Wastewater and Sewerage Design
We design wastewater systems in detail—from parcel connections to main collector lines. We optimize networks based on settlement density, topography, population projections, and existing infrastructure conditions.
We offer new designs for development areas and provide rehabilitation and capacity enhancement solutions for existing systems. In addition to gravity lines, we develop pressure system solutions for regions requiring pumping.
Hydraulic and Capacity Analyses
We perform detailed wastewater flow calculations under various scenarios. By analyzing pipe diameters, slopes, and flow types, we determine system carrying capacity and model it for maximum performance and reliability.
We also assess flood resistance and backflow risk, integrating flood control structures and discharge solutions into the project where needed.
Implementation Support and Technical Documentation
We deliver our designs with complete technical documentation ready for tendering and implementation. The project includes quantity take-offs, bill of quantities, technical specifications, and typical details.
We also provide technical consultancy during field implementation and prepare as-built documentation tailored to the project.

Drinking Water Networks and Transmission Lines
Drinking Water Network Design
The foundation of our drinking water projects is the efficient management of the entire conveyance and distribution process from source to end user. Our network designs are guided by the following principles:
- We integrate all system components from sources (catchments, wells, dam outlets) to storage tanks, transmission lines, distribution networks, and consumer connections.
- We optimize water networks based on population projections, unit water consumption rates, regional topography, and hydraulic pressure requirements.
- When needed, we integrate auxiliary systems such as pressure zoning, regulators, pressure-reducing valves, and balancing tanks.
Hydraulic Modeling and Analysis
To ensure system safety and operational efficiency, we conduct detailed hydraulic analyses for every drinking water project:
- We base pipe diameter and gradient selections on the optimal flow rate-velocity relationship.
- We simulate network behavior under continuous demand and peak usage scenarios.
- We use modeling tools to analyze pressure distribution, reservoir fill levels, fire flow requirements, and day-night consumption dynamics.
- We evaluate looped and grid distribution systems in terms of redundancy and continuity criteria.
Transmission Lines and Main Conveyance Systems
When water sources are distant from settlements, we design long-distance transmission lines and tank supply systems:
- We choose gravity-fed or pressurized pumping systems based on topographic analyses.
- We analyze routing using digital terrain models, land ownership data, environmental constraints, and potential infrastructure conflicts.
- We install robust, long-lasting systems using large-diameter HDPE, ductile iron, steel, or concrete pipes.
3D Modeling and Clash Detection
We design drinking water systems using 3D infrastructure modeling techniques to avoid conflicts with other networks:
- Pipe alignments, elevations, and details are digitally modeled.
- We perform clash detection against systems like sewer, stormwater, electricity, and natural gas that share the same corridor.
- Conflicts are resolved before fieldwork begins, making construction more predictable.
