Uniformat
BCS Architects has asked Redwood Timber Co. which produces wood framing for multi-
family and singe-family homes, what their environmental impacts are during their
manufacturing process. This includes all logging equipment, logging transportation to
their mill, and machinery to plane the trees in their warehouse, and the materials
needed to load the manufactured wood onto a truck to leave their property, and for the
entire use case of the building until it was demoed. This life-cycle analysis for the
environmental impact was to compute what? - Answer -Cradle-to-Grave Analysis
What Construction Delivery Method typically accommodates Fast Track construction as
its creates efficiencies in the workflow? - Answer -Design/Build
In cases of high hydrostatic pressure, a waterproofing barrier must be required. What
type of waterproofing method allows for ease of placement around intricate shapes? -
Answer -Liquid-Applied
When discussing the manufacturing process for Portland Cement - the limestone, shale
mix is added with clay, and iron ore and ran through an extensive production process.
After the raw mix is heated through a kiln, what is added to the Clinker to form the final
product, Portland Cement? - Answer -Gypsum
A one-way joist system uses pans to form the rib-like structure. What does a two-way
concrete joist system use to form the panels? - Answer -Domes
When discussing the quality of Portland Cement, as established by ASTM 150, most
cement that is manufactured in America is what type? - Answer -Correct answer:
Type I and II
What is the primary intention of a proof roll? - Answer -To determine if the ground is
pumping
, When reviewing the below rebar markings - the clouded arrow is pointing at what type
of Steel? - Answer -Carbon Steel
Which of the following is NOT one of the shoring methods discussed? - Answer -Auger
Cast
This type of specialty mixture allows dyes to be added to concrete to create different
colors. The mixture acts as an architectural feature. - Answer -White Portland Cement
An important factor in the concrete mix design is the addition of water. Water chemically
combines with the cement to create strong crystals. What is the typical water to cement
ratio in a mix design? - Answer -Correct answer:
Water shall be 40% to 60% percent of the weight of the cement
When constructing a sidewalk, a concrete finisher purposefully forms a sawed groove in
the sidewalk to create a weak point in the concrete, what is this joint called? - Answer -
Correct answer:
Contraction Joint
Which one of the following is not a reason for Supplementary Materials to be used in a
concrete mix design: - Answer -Increase the shear strength of the concrete
This type of concrete admixture slows the setting of concrete: - Answer -Set-Retarding
Admixture
During the curing process of concrete, water evaporates from the concrete, and causes
shrinkage cracks. This process where heat is created due to the chemical reaction of
the cement and water combining is called: - Answer -Heat of Hydration
When prestressing a beam, the method that is typically used for pre-cast construction is
called - Answer -Pretension
What type of concrete is typically used for a slump flow test? - Answer -Self
Consolidating Concrete
Edges of an excavation can be sloped back at an angle low enough so that soil will not
slide back into hole - Answer -Correct answer:
Angle of Repose
Which one of the below is not a Lean Construction method: - Answer -Ensure all
Materials are Expedited
This type of admixture in a concrete mix design is introduced specifically in freeze/thaw
conditions where the temperature is fluctuating above and below freezing temperatures.
- Answer -Air-Entraining Admixtures
