Now, let us look into the merits and demerits going for either standard equipment or special equipment. Let us compare the merits and demerits of both these options.
Detailed Explanation
In this section, we need to understand the two main categories of equipment used in construction: standard equipment and special equipment. Each has its pros and cons, which can significantly affect the planning and execution of construction projects. Standard equipment refers to commonly used machinery that is readily available, while special equipment is custom-made for specific projects. Knowing the differences is essential for effective equipment management.
Examples & Analogies
Think of standard equipment as a popular brand of car that everyone can buy easily. You can find spare parts quickly, and it's reliable for everyday use. On the other hand, special equipment is like a custom-built sports car designed for a specific purpose, such as racing. While it may perform exceptionally well in the right context, it’s not something everyone has access to, and parts may not be readily available.

When you go for the choice of standard equipments they are basically commonly available because there will be lot of manufacturers available for the standard equipments. Because it is used commonly in so many construction project sites and its delivery will also be very quicker.
Detailed Explanation
Standard equipment is advantageous because it is widely available across the market. Numerous manufacturers offer standard equipment models, making it cheaper and quicker to source. This means that if a project requires equipment, contractors can obtain it without lengthy delays. Additionally, since these machines are commonly used, spare parts are easily accessible, which minimizes downtime when repairs are needed.
Examples & Analogies
For example, consider a standard bulldozer. If a construction crew needs a bulldozer quickly because theirs broke down, they can usually find another one from a local rental company without delay. They won't have to wait for weeks or months to get a replacement.
