Infrastructure Design Drafter Course

Lesson 1 • Drawing Standards and Conventions

Covers line types, sheet layouts, title blocks, and notation conventions used in infrastructure drawings. Provides the universal grammar students apply throughout the course.

Lesson 2 • The Infrastructure Drafter's Role

Defines responsibilities, deliverables, and collaboration points within project teams. Grounds students in professional expectations before technical skills are introduced.

Lesson 3 • Units, Scales, and Coordinate Systems

Introduces measurement units, drawing scales, and geographic coordinate systems relevant to infrastructure work. Ensures accurate spatial representation in all subsequent drawings.

Lesson 1 • Core 2D Drawing Commands

Covers line, arc, polyline, circle, and offset commands used to construct infrastructure geometry. These commands form the building blocks of every drawing produced in the course.

Lesson 2 • Layers, Blocks, and Attributes

Teaches layer management, reusable block creation, and attribute data embedding. Proper layer and block use is mandatory for professional infrastructure drawing sets.

Lesson 3 • Plotting and File Management

Covers plot settings, PDF output, and file naming conventions for drawing submission. Proper file management prevents version conflicts and supports team collaboration.

Lesson 4 • CAD Interface and Workspace Setup

Orients students to the CAD environment, toolbars, and workspace customization. A configured workspace reduces errors and improves drafting speed from the start.

Lesson 1 • Grading Plan Production

Applies existing and proposed surface data to produce grading plans with spot elevations and slope indicators. Grading plans are a core deliverable in site infrastructure packages.

Lesson 2 • Surface Modeling and Contour Generation

Builds triangulated irregular network (TIN) surfaces and generates contour lines from point data. These surfaces underpin grading, drainage, and utility design drawings.

Lesson 3 • Survey Data Types and Sources

Identifies field survey, aerial, and LiDAR data formats used in infrastructure projects. Understanding data sources allows drafters to select and import the correct inputs.

Lesson 4 • Cross Sections and Profiles from Terrain

Extracts longitudinal profiles and cross sections from surface models along defined alignments. These views are required for road, drainage, and utility corridor drawings.

Lesson 1 • Horizontal Alignment Drafting

Draws tangent lines, circular curves, and spiral transitions that define road centerlines. Correct horizontal geometry is the starting point for all road design drawings.

Lesson 2 • Pavement Marking and Signage Plans

Creates plan-view drawings showing lane markings, symbols, and sign locations. These drawings coordinate with traffic engineering and are part of the final road package.

Lesson 3 • Intersection and Turning Movement Details

Drafts intersection geometry, curb radii, and turning lane configurations. Intersection details require precise geometry and clear annotation for construction accuracy.

Lesson 4 • Vertical Profile and Grade Design

Drafts vertical alignment profiles showing existing ground and proposed grade lines with vertical curves. Profiles communicate cut-and-fill depths and drainage gradients to contractors.

Lesson 1 • Detention Basin and Grading Plans

Combines grading and drainage data to produce detention basin layout and grading drawings. These drawings integrate surface modeling skills with drainage system design.

Lesson 2 • Storm Drain Plan View Drawing

Drafts plan-view layouts of pipe networks, structure locations, and flow direction arrows. Plan drawings communicate the horizontal layout of the entire drainage system.

Lesson 3 • Drainage Structure Detail Sheets

Drafts construction details for inlets, manholes, headwalls, and outlet structures. Detail sheets provide fabrication and installation dimensions not visible in plan or profile views.

Lesson 4 • Drainage System Components and Symbols

Identifies inlets, manholes, pipes, channels, and detention basins and their standard drawing symbols. Symbol literacy is prerequisite to drafting any drainage plan.

Lesson 1 • Water Distribution System Drawing

Drafts water main layouts, valve locations, hydrant placements, and service connections. Water system drawings must show isolation and access points for maintenance planning.

Lesson 2 • Utility Composite and Coordination Drawings

Overlays multiple utility systems onto a single composite drawing to identify and resolve conflicts. Composite drawings are the primary coordination tool in multi-utility corridors.

Lesson 3 • Utility Corridor Concepts and Conflicts

Explains utility corridor allocation, separation requirements, and conflict identification. Understanding spatial constraints prevents costly clashes during construction.

Lesson 4 • Gas and Electrical Conduit Drafting

Covers drafting of gas distribution mains and electrical conduit banks in plan and section views. These systems require specific safety notation and separation callouts.

Lesson 1 • Culvert and Bridge Structure Details

Produces plan, elevation, and section drawings for box culverts, pipe culverts, and small bridges. These details coordinate hydraulic, structural, and roadway geometry requirements.

Lesson 2 • Reinforced Concrete Detail Conventions

Covers rebar notation, bar schedules, and concrete section drawing standards. Correct reinforcement detailing is essential for structural safety and contractor compliance.

Lesson 3 • Foundation and Subgrade Detail Drawing

Drafts spread footing, pile cap, and subgrade improvement details for infrastructure structures. Foundation details must convey bearing depth, reinforcement, and compaction requirements.

Lesson 4 • Detail Sheet Organization and Referencing

Organizes multiple details onto sheets with consistent callout bubbles, scales, and cross-references. Well-organized detail sheets reduce field errors and RFI volume during construction.

Lesson 1 • As-Built Drawing Production

Updates design drawings with field-verified dimensions and locations to produce as-built records. As-built drawings are a contractual deliverable and a critical reference for future maintenance.

Lesson 2 • Permit and Regulatory Submission Preparation

Prepares drawing sets for regulatory review by applying required stamps, notes, and submission formats. Understanding submission requirements prevents delays in the approval process.

Lesson 3 • Quantity Takeoff from Drawings

Extracts pipe lengths, earthwork volumes, pavement areas, and structure counts from completed drawings. Accurate takeoffs support cost estimation and bid document preparation.

Lesson 4 • Cross-Discipline Coordination Review

Checks alignment, elevation, and detail consistency across civil, structural, and utility drawings. Coordination review catches conflicts before submission and reduces costly change orders.
