Q

What are the properties of silt?

A

Stable when dry or damp unstable when wet
Swells when frozen, compresses under load.
Generally building foundations and road bases need to extend below silt or be elastic enough to avoid damage.
Some non-plastic silts are suitable for lighter loads.

Q

What are the four basic categories of roads?

A

Local streets- direct access to buildings, grids or cul-de-sacs
Collector streets- Connect local and arterial, use stop signs
Arterial streets- continuous circulation routes, 2-3 lanes, typ. no street parking, direct access to buildings should be avoided
Expressways- Limited access, ramps, no peds, use lots of space and create noise.

40’ beyond building perimeter
5’ beyond primary roadway curbs and walks
25’ beyond constructed areas with permeable surfaces

31

34
Q

When and where was the first zoning ordinance passed?

A

1916 New York City

35
Q

What does zoning primarily regulate?

  • Often used in subdivisions- setbacks, min sf of houses, exterior material restrictions
  • Generally established for a certain period 10-30 years
39
Q

Building Construction
Appraisal
Financing
Professional Fees
Permits
Maintenance of completed structure
40
Q

What are three basic ways land is valued?

A

Market- compare surrounding properties that have recently sold
Income- potential of the property to yield profit
Cost- estimated at highest and best use then cost to improve or replace buildings is included

41
Q

What is the formula for property taxes with a mill levy?

A

Mill levy = $1/1000 = 1/10 of a cent
Formula:
(Assessed Valuation%) x (Actual Value) = Assessed Value
(Mill Levy) x (Assessed Value) = Yearly Tax

42

A

A tax based on the value of the property being taxed.

46
Q

What is a special sales tax?

A

A tax imposed for any specific purpose such as a major transportation project.
Requires majority vote of people in district.

47
Q

What are general obligation bonds?

A

Backed by general tax revenue and issuer’s credit.

What is tax-increment financing?

A

A city pays for an improvement based on anticipated increased taxes due to increased property values.
At end of development period the increased taxes go to pay off bonds issued at the beginning of the redevelopment.
Does not require majority vote.

50
Q

What are development impact fees?

A

Charged to developers for off-site infrastructure improvements made necessary by a development.
Questions of how fees are calculated and who really benefits make impact fees controversial.

51
Q

What are subdivision exactions?

A

Like development impact fees but used to contribute land or cash to buy land for public use. ex: parks

52
Q

What are special district assesments?

A

AKA BIDS or benefit assessments
Fees used to fund public space improvements to enhance an area’s appeal
If majority of property owners in area agree to arrangement then all owners must pay fees.

53
Q

What should be included in an existing building survey?

54
Q

What is EDM?

A

Electromagnetic distance measurement.
Laser measures distance and angle to a reflective prism.
Requires two people to use.
+/- 1/64”

55
Q

What is REDM?

A

Reflectorless electromagnetic distance measurement.
Laser relies on reflection from object being measured.
+/- 1/8” Less accurate than EDM.

56
Q

What is Rectified Photography?

A

Camera is set parallel to the facade to give a flat image with no perspective distortion. Dimensions can be scaled off the image.

57
Q

What is Orthophotography

A

Like rectified photography but uses digital images and software to correct optical distortion.

58
Q

What is Stereophotogrammetry?

A

Uses two overlapping photographs in a computer software to create 3-D drawings.

59
Q

What is Convergent Photogrammetry?

A

Uses multiple oblique images to create a 3-D drawing.

60
Q

What is Laser Scanning?

A

Uses medium-range pulsing laser beams, to obtain 3-D coordinates to produce a point cloud.

61
Q

What standards must be met for a rehab project to earn federal tax credits?

A

The Secretary of the Interior’s Standards for Rehabilitation

62
Q

What are the four historical treatments of historic buildings from most to least historically accurate?

A

Preservation- retain all historic fabric through conservation maintenance and repair. Includes respectful changes and alterations.
Rehabilitation- retention and repair of historic materials, but with more leeway assuming a more deteriorated building
Restoration- focuses on most significant time period permitting removal of changes and alterations.
Reconstruction- recreate non-surviving site or building with new materials.

63
Q

What is AIA Document B141?

A

Owner-Architect Agreement

States among other things that the architect is responsible for code compliance.

64
Q

What is AIA Document C141?

A

The Architect-Consultant Agreement
States among other things: that the consultant is responsible for code compliance regarding their area of work.
Also the consultant is responsible for accurate production of their drawings and specs. And for checking their own documents for consistency.
However the architect is ultimately liable to the client for the consultant’s work.
