PART 1

 

Scaffolding and Hoisting

 

The lifting for the masonry work is provided by either scaffolding or a hoist. Accounting for the scaffolding and hoisting is often a confusing issue for an estimator who is new to the profession. Decide which type of scaffold or lift would be the most efficient for the following scenarios:

 

•Scenario 1: You are estimating a small, commercial retail building with 16-foot walls. Most of the storefront is window space with the masonry on the front only and around the windows to a height of 8 feet.

 

•Scenario 2: You are estimating a four-story dormitory with masonry on all sides.

 

•Scenario 3: You are estimating a small, commercial office building with 16-foot walls. Terrain at the front of the building is irregular. Masonry is around the entire building.

 

Resources:

 

•Use the course textbook Walker’s Building Estimator’s Reference Book.

 

Perform an Internet search with the keywords “The NC labor guide to scaffolding pdf.”

 

 

 

Part 2

 

Structural Steel

 

Steel is most often subcontracted; but a good understanding of structural steel is important to general contractors in order to verify the work or to perform small jobs.

 

For each of the following instances, decide which sections of the steel construction will be subcontracted and which sections will be self-performed by a general contractor. Give your reasoning for each.

 

•Steel decking on a retail strip mall

 

•Structural steel on a commercial office building

 

•A steel stairway to the roof attached to the outside of the building

 

Note: For guidance, use Walker’s Building Estimator’s Reference Book and the chapter “Metals” of your course textbook Estimating in Building Construction.
