Specialized Engineering Segments

PRNAV CAD operates as an enterprise layout design vendor and premium technical contractor mapping complex infrastructural parameters across 4 specialized segments:

City Gas Distribution Work

1. City Gas Distribution Work

Providing highly accurate routing plans and underground pipeline alignment blueprints for City Gas Distribution networks to ensure safe gas transport.

We provide comprehensive drafting and alignment solutions for City Gas Distribution (CGD) networks. Our CAD engineering team specializes in mapping highly accurate underground pipeline routing plans that ensure safe and efficient high-pressure gas transport across urban sectors.

What We Offer in CGD

Route Alignment Mapping Optimum pipeline paths avoiding underground utilities and difficult terrains.
L-Section / Profile Drawings Detailed depth profiling, bending radius calculations, and BOQ estimation.
Special Crossings Layout Custom engineered blueprints for river, highway, and railway crossings.

Our Value: With our precision drafting, contractors save significantly on material wastage and reduce on-site execution hurdles.

Electrical Work

2. Electrical Work

Delivering robust Single Line Diagrams, trench routing, and High Voltage Substation blueprints optimized for industrial energy efficiency.

Robust electrical grids demand flawless schematic drafting. We provide high-quality engineering layouts for High Voltage / Low Voltage (HV/LV) networks and substations, ensuring strict adherence to international electrical safety protocols.

Our Electrical CAD Services

Single Line Diagrams (SLD) Detailed electrical routing and switchgear placement for commercial grids.
Cable Trench Routing Spatial routing blueprints for primary and secondary underground cabling networks.
Substation Design Layouts Accurate alignments for transformers, control panels, and high-voltage corridors.

Our Value: We standardize components using AutoCAD Electrical to deliver a highly optimized network that minimizes voltage drops and energy inefficiencies.

Opticals Cable Work

4. Opticals Cable Work

Creating high-precision Horizontal Directional Drilling (HDD) profiles and trenchless routes to ensure zero utility strikes during cable laying.

Underground Optical Fiber Cable (OFC) laying requires extreme precision to avoid striking existing utilities. Our drafting experts create exact mathematical profiles and trenchless directional drilling (HDD) layouts for seamless telecom expansion.

OFC & HDD Drafting Details

HDD Profile Generation Accurate entry angles, bending radius, and depth profiles for trenchless bores.
Utility Identification Mapping Mapping existing sewers, water lines, and electrical cables to prevent strikes.
As-Built Documentation Final documented drawings perfectly matching the executed bore log on-site.

Our Value: Our detailed profiles enable contracting teams to execute OFC laying under national highways and rivers with zero utility damage.
