About InfraDigital CAD

The Professional Highway Design & BIM Automation Platform

Our Mission & Purpose

InfraDigital CAD was created to eliminate the friction between complex computer-aided design modeling environments (such as Autodesk Civil 3D) and submission-ready engineering schedules, calculations, and reports.

In daily civil infrastructure consulting, design engineers and surveyors spend countless hours manually parsing raw CSV coordinate dumps, re-typing horizontal curve parameters, checking superelevation transition chainages, and calculating pavement layer thicknesses. InfraDigital CAD provides dedicated, client-side engineering tools that automate these formatting and calculation workflows with mathematical precision.

Who We Serve

Highway & Road Engineers

Designers validating curve radii, stopping sight distances, superelevation runoffs, and structural pavement layer structures.

Surveyors & BIM Specialists

Professionals cleaning large PENZD CSV files, LandXML alignment exports, and checking longitudinal grades and terrain classifications.

Cost Estimators & Students

Engineers compiling earthwork volumes, hierarchical Bills of Quantities (BoQ), and studying international highway design guidelines.

Engineering Disciplines Covered

Highway Geometric DesignHorizontal curves, vertical parabolic profiles, superelevation runoffs, and sight distances.
Pavement Structural DesignFlexible catalogue design (ERA T1-T8/S1-S6), AASHTO structural numbers, and rigid JPCP slabs.
Drainage and HydraulicsRational method catchment runoff, pipe/box culvert sizing, and trapezoidal ditch flow.
Survey and Terrain AnalysisPENZD coordinate cleansing, longitudinal grade analysis, and expansive soil classification.
Earthworks OptimizationMass haul diagram balance lines, overhaul haul economics, and cross-section volume checks.
Roadside Safety EngineeringEmbankment hazard warrants, clear zone recovery calculation, and barrier length of need.
Quantity Surveying & BoQStandard specification pay-item mapping, earthwork variance indices, and cost takeoff.
CAD / Civil 3D AutomationLandXML alignment extraction, centerline matrix generation, and station equation correction.
Engineering DocumentationISO 19650 structured drawing folder organization and PDF engineering report generation.

Referenced Engineering Standards

Our calculation and validation routines implement standard formulas and criteria sourced from established technical authorities:

  • ERA 2013 Highway Manuals: Geometric Design Manual (2013), Pavement Design Manual Vol I & II (2013), Drainage Design Manual (2013), Site Investigation Manual, and Standard Technical Specifications.
  • AASHTO Guidelines: A Policy on Geometric Design of Highways and Streets (Green Book, 7th Edition), AASHTO Guide for Design of Pavement Structures (1993), and Roadside Design Guide (4th Edition).
  • AACRA Standards: Addis Ababa City Roads Authority Urban Street Design Manuals.
  • Hydraulic & BIM Standards: Manning's equation for open channels, FHWA Hydraulic Design Series (HDS-5), and ISO 19650 / BS 1192 for folder structures.

Client-Side In-Browser Processing Architecture

Engineering design files represent proprietary project data. InfraDigital CAD operates with a browser-local computation architecture designed to keep uploaded engineering files within the user's local browser during processing.

When you upload an Excel workbook, CSV survey export, or LandXML file, the data is parsed and computed entirely in your browser memory using client-side JavaScript. No project coordinates, survey points, or alignment geometries are ever sent to an external server, database, or third-party cloud.

Yonatan Abrham

Highway Design Engineer | BIM/Civil 3D Specialist | Aspiring Project Manager | Interested in AI & Technology

I’m a Highway Engineer with hands-on experience in road design, alignment optimization, and construction management. I specialize in creating cost-effective designs, solving right-of-way issues, and preparing accurate road cross-sections for smooth project execution.

By combining civil engineering expertise with modern programming tools, I build automation scripts and integrations that eliminate repetitive drafting tasks, helping engineering teams focus on creative design and deliver infrastructure solutions on time and within budget.
