Construction Estimates: Woodworks Part 1 (Introduction)

Summary

In this pre-recorded lecture, the speaker introduces the concept of woodworks in construction, explaining its importance as a material derived from trees, including roots, branches, and trunks. Key terms such as timber, lumber, boards, and blocks are defined, highlighting their differences in processing and dimensions. The lecture focuses on estimation techniques for woodworks, particularly how to calculate quantities in pieces and board feet. It also discusses the common sizes of wood available in the Philippines and the importance of understanding board foot calculations for construction projects.

Takeaways

• 😀 Woodwork refers to the construction process using fibers from trees' roots, branches, and trunks.
• 😀 Timber is untreated raw wood, while lumber is processed timber used for construction.
• 😀 Boards are a type of lumber with a thickness less than 4 cm and a width of at least 10 cm.
• 😀 A plank is a piece of lumber that is 4 to 5 inches thick.
• 😀 Formwork and falsework are types of woodwork but will be discussed separately in another video.
• 😀 Woodwork estimation involves computing quantities like the number of pieces required for construction.
• 😀 Board foot is a unit of measurement for wood volume, equivalent to 1 foot by 1 foot by 1 inch.
• 😀 1 board foot is equal to 144 cubic inches.
• 😀 To calculate wood volume in board feet, convert dimensions into inches, then use the conversion factor of 1 board foot = 144 cubic inches.
• 😀 In the Philippines, wood is typically sold in lengths of 10 to 20 feet, with 12 feet being the most common.
• 😀 Despite the SI unit system being followed in the Philippines, board feet remain the standard unit for wood measurement in construction.

Q & A

What is woodwork in the context of construction?

Woodwork refers to the construction process where fibers from roots, branches, and trunks of trees are used as construction materials, commonly known as wood.

What is the difference between timber and lumber?

Timber is untreated wood directly from the tree, whereas lumber is processed timber that has been treated and cut for construction purposes.

What defines a 'board' in woodwork terminology?

A board is a type of lumber where its thickness is less than 4 cm, and its width is at least 10 cm, according to the book by Max Fajardo.

How do the dimensions of lumber differ?

Lumber can differ in terms of size, with types such as boards and planks, where planks are typically thicker than boards (around 4 to 5 inches thick).

What is a board foot in woodwork measurement?

A board foot is a unit of volume for wood, equivalent to 1 foot by 1 foot by 1 inch in dimensions, or 144 cubic inches.

How do you calculate the volume of wood in board feet?

To calculate the volume of wood in board feet, multiply the length, width, and thickness in inches, then divide the result by 144 to convert to board feet.

Why is the board foot used for wood measurement in the Philippines?

Despite the Philippines using SI units, board foot is the recognized standard for wood volume in the country, especially in hardware stores.

What is an example of how to convert dimensions to board feet?

For instance, a piece of wood measuring 2 inches by 3 inches by 14 feet can be converted to board feet by multiplying the dimensions and dividing by 12, resulting in 7 board feet.

What are some commonly available wood lengths in the Philippines?

Commonly available wood lengths in the Philippines are 10 feet, 12 feet, 14 feet, 16 feet, 18 feet, and 20 feet.

What is the importance of understanding board foot calculation for wood estimation?

Understanding board foot calculation is essential for accurate wood estimation in construction, allowing for proper material ordering and cost planning.
