Introduces calipers, micrometers, levels, and gauges used in mechanical construction. Accurate measurement underpins quality in every subsequent fabrication task.

Lesson 3 • Industry Overview and Career Pathways

Introduces the mechanical construction industry scope, key trades, and professional roles. Provides context for all subsequent technical content.

Lesson 4 • Engineering Materials and Properties

Covers metals, alloys, polymers, and composites used in mechanical systems. Material selection directly affects structural integrity and system performance.

Lesson 1 • Layout and Marking Techniques

Teaches scribing, centre-punching, and template use for accurate steel layout. Precise marking reduces rework and material waste during fabrication.

Lesson 2 • Structural Inspection and Documentation

Introduces visual inspection criteria, non-destructive testing basics, and as-built records. Documentation supports quality assurance and regulatory compliance.

Lesson 3 • Bolted Connection Methods

Explains bolt grades, hole preparation, and torque specifications for structural joints. Proper bolt installation ensures connection integrity under dynamic loads.

Lesson 4 • Steel Member Classification and Selection

Covers wide-flange, channel, angle, and hollow sections and their load applications. Correct member selection prevents structural failure under design loads.

Lesson 1 • Weld Symbols and Quality Inspection

Teaches reading weld symbols, performing visual inspection, and applying acceptance criteria. Quality control at this stage prevents costly rework in assembly.

Lesson 2 • Welding Fundamentals and Equipment Setup

Covers arc physics, machine settings, and electrode selection for common processes. Correct setup is the foundation of consistent, defect-free weld quality.

Lesson 3 • Gas Metal Arc Welding (MIG/GMAW)

Covers wire feed, shielding gas selection, and transfer modes for MIG welding. MIG is the primary process for high-productivity fabrication shop work.

Lesson 4 • Shielded Metal Arc Welding (SMAW)

Teaches stick welding technique for flat, horizontal, vertical, and overhead positions. SMAW is the baseline process for structural steel and field repair work.

Lesson 1 • Pipe Materials and Pressure Ratings

Covers carbon steel, stainless steel, copper, and plastic pipe specifications. Material and pressure rating selection determines system safety and service life.

Lesson 2 • Isometric Drawing Interpretation

Teaches reading pipe isometrics, spool sheets, and flow diagrams for installation planning. Isometric literacy enables accurate material take-off and routing decisions.

Lesson 3 • Pipe Fittings, Flanges, and Valves

Identifies elbows, tees, reducers, flanges, and valve types used in process piping. Correct fitting selection ensures leak-free, maintainable system connections.

Lesson 4 • Pipe Cutting, Fitting, and Joining

Covers cutting methods, beveling, fit-up, and joining techniques for various pipe materials. Proper joint preparation is critical to weld quality and system integrity.

Lesson 1 • Rigging and Lifting Operations

Teaches sling selection, load calculation, and crane signal communication for safe lifts. Rigging competency is prerequisite to all equipment placement tasks.

Lesson 2 • Precision Shaft Alignment

Introduces dial indicator and laser alignment methods for coupled rotating equipment. Misalignment is the leading cause of premature bearing and seal failure.

Lesson 3 • Pre-commissioning and Functional Testing

Addresses lubrication, rotation checks, and vibration baseline measurement before startup. Pre-commissioning steps prevent equipment damage during initial operation.

Lesson 4 • Foundation and Baseplate Preparation

Covers anchor bolt layout, chipping, and surface preparation for equipment foundations. A properly prepared foundation ensures stable, vibration-free equipment operation.

Lesson 1 • Ductwork Fabrication and Installation

Covers sheet metal gauges, seam types, and hanger spacing for rectangular and round duct. Airtight ductwork is essential for system efficiency and indoor air quality.

Lesson 2 • System Balancing and Performance Testing

Introduces airflow measurement, water flow balancing, and performance verification procedures. Balanced systems deliver design conditions and minimise energy consumption.

Lesson 3 • Refrigerant Piping and Handling

Teaches refrigerant line sizing, brazing technique, and safe refrigerant handling practices. Proper refrigerant management protects equipment and meets environmental regulations.

Lesson 4 • HVAC System Components and Functions

Identifies air handling units, chillers, cooling towers, and terminal devices. Understanding component function guides correct installation sequencing and coordination.

Lesson 1 • CNC Machine Operation Fundamentals

Covers G-code basics, machine homing, and tool offset entry for CNC mills and lathes. CNC operation enables repeatable, high-accuracy part production at scale.

Lesson 2 • Turning and Milling Operations

Teaches facing, turning, boring, and milling operations for producing mechanical components. Correct cutting parameters extend tool life and achieve surface finish requirements.

Lesson 3 • Quality Control in Fabrication

Introduces first-article inspection, statistical process control basics, and non-conformance reporting. Systematic quality control reduces scrap and ensures customer specifications are met.

Lesson 4 • Custom Bracket and Support Fabrication

Applies layout, cutting, and welding skills to fabricate custom structural supports. Custom fabrication solves field installation challenges not addressed by standard components.

Lesson 1 • Material and Equipment Procurement

Addresses material take-off, vendor qualification, and expediting for construction projects. Timely procurement keeps installation crews productive and on schedule.

Lesson 2 • Site Coordination and Trade Interfaces

Covers coordination meetings, clash resolution, and interface management between trades. Proactive coordination prevents costly rework caused by conflicting installations.

Lesson 3 • Cost Control and Change Management

Introduces earned value analysis, change order processing, and budget variance reporting. Cost control skills protect project profitability and client relationships.

Lesson 4 • Construction Planning and Scheduling

Covers work breakdown structures, critical path method, and resource-loaded schedules. Effective planning prevents delays and cost overruns on mechanical projects.
