NCCER Module 22106: Grades and Grading

Course Overview

Module ID: 22106 Craft: Heavy Equipment Operations (Level One) Duration: 15 Hours Credit Hours: 1.5 (CEU)

Description This module introduces trainees to the fundamental concepts of preparing and establishing graded surfaces using heavy equipment. Trainees will learn to identify and interpret construction stakes and markings, calculate slopes and percentages of grade, and understand the role of grading in site preparation. The module emphasizes safe and accurate grade work to ensure proper drainage, stability, and compliance with project specifications.

Prerequisites

• Completion of NCCER Core Curriculum (Module 00101 or equivalent)
• Basic understanding of heavy equipment safety and operation (recommended)

Required Materials

• NCCER Heavy Equipment Operations Level One Trainee Guide
• NCCER Module 22106 PowerPoint slides (if available)
• Personal protective equipment (PPE): hard hat, safety glasses, gloves, steel-toed boots
• Calculator, notebook, and pen/pencil
• Access to grading tools for hands-on practice (e.g., laser level, grading rod, tape measure)

Learning Objectives

Upon successful completion of this module, trainees will be able to:

1. Explain key terms and concepts associated with grades and grading in construction.
2. Identify common types of construction stakes and interpret their markings (e.g., cut/fill, slope ratios).
3. Calculate slope ratios, percentages of grade, and cut/fill requirements.
4. Describe the purposes of grading and its importance in site work.
5. Identify and explain the use of manual and automatic leveling instruments, including laser levels and GPS technology for grading.
6. Perform basic grade-checking tasks safely and accurately.

Performance Tasks

Trainees must demonstrate proficiency in the following NCCER-approved performance tasks under instructor supervision:

1. Identify and interpret various types of grade stakes and markings from examples or on-site setups.
2. Calculate slope ratios and percentages of grade using provided data.
3. Set up and take readings using a laser level or automatic level.
4. Verify grade using a grading rod and interpret cut/fill information.

Performance tasks are verified by the instructor and documented for NCCER certification credit.

Course Outline

Section 1: Introduction to Grades (2.5 hours)

• Definition and purposes of grading
• Importance of accurate grading for drainage, stability, and foundation preparation
• Overview of grade work in heavy equipment operations

Section 2: Grade Stakes and Markings (4 hours)

• Types of stakes: benchmarks, hubs, cut/fill stakes, slope stakes
• Interpreting stake markings (e.g., C for cut, F for fill, slope ratios like 4:1)
• Common notations and symbols (e.g., F/S, circled numbers, offsets)
• Hands-on: Identifying and reading sample stakes

Section 3: Slope Ratios and Grade Calculations (4 hours)

• Understanding slope ratios (horizontal:vertical)
• Calculating percentage of grade (rise/run × 100)
• Positive and negative grades
• Cut and fill computations
• Math exercises and real-world examples

Section 4: Leveling and Grading Instruments (3 hours)

• Manual levels, rods, and backsight/foresight readings
• Rotating laser levels and their advantages
• Introduction to GPS and machine control systems for grading
• Safety considerations when using leveling equipment

Section 5: Practical Application and Review (1.5 hours)

• Grade checking procedures
• Common errors and troubleshooting
• Review of performance tasks
• Module exam preparation

Assessment Methods

• Written Examination: Multiple-choice questions covering all objectives (minimum passing score: 70%)
• Performance Verification: Hands-on demonstration of required tasks (must achieve satisfactory rating on all tasks)
• Participation and Attendance: Active engagement in discussions and hands-on activities

Grading Policy

• Module Examination: 70%
• Performance Tasks: 30%
• Overall passing requirement: 70% on written exam and satisfactory completion of all performance tasks

Certification

Successful completion (passing exam and verified performance tasks) earns trainees credit toward NCCER Heavy Equipment Operations Level One certification. Credentials are recorded in the NCCER National Registry.

Instructor Notes

• Emphasize safety throughout, referencing NCCER Heavy Equipment Safety standards.
• Incorporate real-world examples and site visits if possible.
• Use visual aids, such as stake diagrams and equipment demonstrations, to reinforce concepts.
