May 2022 CE Past Board Exam Problems in Mathematics, Surveying, and Transportation Engineering

Summary

This video script delves into the principles of applied mathematics in various engineering fields, focusing on transportation and highway construction management. It covers essential elements like navigation, guidance, and control for highway design, safety measures such as scaffolding capacity and protective systems against cave-ins, and the importance of formwork in concrete construction. Additionally, it touches on project management tools like PERT/CPM networks and the significance of contracts and safety culture, including toolbox meetings and profile completion post-construction.

Takeaways

• 🛣️ The basic lane width suitable for National Road is 3.35 meters, which is crucial for transportation planning.
• 🚦 Chevron signs are used to guide drivers through changes in the horizontal alignments of the road, enhancing road safety.
• 🏗 Scaffolding must have a capacity at least four times its own weight to ensure stability and safety during construction.
• 🚗 Driving tasks can range from complex to boring, requiring careful consideration by highway designers to accommodate different driver capabilities.
• 🚧 Protective systems like sloping, benching, and shield systems are essential for preventing cave-ins and ensuring worker safety in excavations.
• 📝 Specifications provide detailed requirements for materials, equipment, and workmanship in construction projects.
• ⏱ When preparing a PERT/CPM Network diagram for a construction job, time scheduling is a critical factor to consider.
• 🛠 The ability of a material to dissipate or deaden mechanical vibrations is an important property in construction materials.
• 📊 A profile drawing is a representation with vertical axis and horizontal distance measured along the center line of the facility, useful for visualizing elevation changes.
• 📑 A contract is a formal agreement between two parties, often legally binding, which outlines the terms of a construction project.
• 🗣️ Toolbox meetings are informal group discussions focusing on safety issues, promoting a culture of safety on job sites.
• 🏗️ Formwork is the temporary structure used to support the shape of concrete before it sets, essential in building construction.
• 📏 Benching is a method of protecting workers from cave-ins by excavating the sides of an excavation to form horizontal levels or steps.
• 📊 Queuing diagrams are important for analyzing and understanding the flow and wait times in various processes, including construction.

Q & A

What is the appropriate basic lane width for a National Road according to the surveying principles mentioned in the script?

The appropriate basic lane width for a National Road is 3.35 meters.

What are the Chevron signs used for in road design?

Chevron signs are used to guide drivers through a change in horizontal alignments of the road.

What is the minimum capacity requirement for all scaffoldings in construction?

The minimum capacity requirement for all scaffoldings is to support at least four times its own weight.

What are the three essential elements that a highway designer should consider?

The three essential elements a highway designer should consider are navigation, guidance, and control.

What is the purpose of the protective system in excavation work?

The purpose of the protective system in excavation work is to protect employees from cave-ins, material falling or rolling from an excavation face, or the collapse of adjacent structures.

What is the term used to describe the bucket volume contained within the bucket when following the outline of the bucket sides?

The term used is not provided in the script, as it is interrupted by music.

What are guide signs in the context of road users?

Guide signs inform road users about the direction and distances of destinations on the route they are following or along other roads that intersect their route.

What does the term 'specifications' refer to in a construction project?

Specifications provide the detailed requirements for the materials, equipment, and workmanship to be incorporated into the project.

What should be considered when preparing a PERT CPM Network diagram for a construction job?

Time scheduling should be considered in the preparation of the PERT CPM Network diagram.

What is the significance of a material's ability to dissipate or deaden mechanical vibrations?

The significance of a material's ability to dissipate or deaden mechanical vibrations is not explicitly stated in the script, but it generally refers to the material's capacity to reduce the impact of vibrations, which can be important in various engineering applications.

What is the term used for a drawing that has its vertical axis and horizontal distance measured along the center line of the facility?

The term used is not provided in the script, as it is interrupted by music.

What is the term for a formal or legally binding agreement between two parties?

A formal or legally binding agreement between two parties is referred to as a contract.

What is a toolbox meeting in the context of safety discussions on job sites?

A toolbox meeting is an informal group discussion that focuses on a particular safety issue and is used to promote department safety culture as well as to facilitate health and safety discussions on job sites.

What is the term used for the process that occurs after the completion of construction and the resolution of the majority of punch list and commissioning issues?

The term used is 'profile', although it may be a misinterpretation as the script is interrupted by music.

What is the term for the process in building construction where concrete is placed in a form or mold because it cannot maintain a particular shape before it sets?

The term for this process is 'form work'.

What is the term for a method of protecting workers from cave-ins by excavating the sides of an excavation to form one or a series of horizontal levels or steps?

The term for this method is 'benching'.

What determines the safe capacity of piles driven by powered hammers?

The safe capacity of piles driven by powered hammers is based on all of the above factors mentioned in the script, although the specific factors are not detailed due to the music interruption.

What devices are generally used to provide delineation as part of the road alignment design process?

All of the above devices mentioned in the script are used for delineation, although the specific devices are not detailed due to the music interruption.

What are some important properties of queuing diagrams?

The important properties of queuing diagrams are not detailed in the script due to the music interruption, but they generally include aspects such as waiting time, service time, and system capacity.
