Q

What is the difference between the Specifications and the Working Drawing ?

A

Working Drawings

  • Show location, height and gauge-thickness of HVAC duct.

Specification

  • State the SMACNA requirements and all other detailed information needed to construct duct.
17
Q

  1. Site plans
  2. Floor plans
  3. Exterior elevation views
  4. Interior elevation views
  5. Material specifications
  6. Building section views
  7. Detail section views
18
Q

Engineering Drawing contain what required HVAC info ?

A
  1. Structural drawings - location of sleeve for duct penetrations
  2. Mechanical drawings - info on HVAC systems
  3. Plumbing drawings - equipment schedules
  4. Electrical drawings - lighting layout for diffusor placement
19
Q

What are the 6 steps you should do when first looking at blueprints ?

A

Look at :

  1. Archectural Drawing - elevations
  2. Exterior Elevations and Floor plans - locations of air intake and exhausts
  3. Floor plan and Interior elevations together - locate fire dapers, duct work, diffusers
  4. Room finish schedules - diffuer style
  5. ALL Mechinical drawings - look for collisions
  6. Mechanical specifications - material types and gauges
20
Q

Any changes to the drawing are referred to as what ?

A

as-builds

21
Q

Do we orally agree to a drawing change that is going to cost more money ?

YES or NO

A

NO

Must have written consent called a CHANGE ORDER

22
Q

What is the National Master Specification (NMS) ?

A

Is a comprehensive library of construction specification sections used by both goverment and private industry.

23
Q

What is BIM (building information management) ?

A

A digital tool that speeds up the access of building information.

It integrates 3D drawings and 4D animations to convey informtion throught the construction.

24
Q

What are the 2 basic types of standards referred in the NMS (national master specification) ?

A
  1. Standard Specifications
  2. Standard Methods and Practices
25
Q

A 1000 cfm of air is to be moved through a duct system with a total pressure of 0.4”wc. Which type of fan is the best for the installation?

  1. Propeller Fan
  2. Tube Axial Fan
  3. Vane Axial Fan
  4. Forward Curved Blade Centrifugal Fan
A
  1. Forward Curved Blade Centrifugal Fan

  1. radial blades
  2. backward curved blades
  3. forward curved blades
  4. inline blades
A
  1. radial blades
29
Q

Which fan should be NEVER used in a ductless system ?

  1. propeller fan
  2. tube axial fan
  3. vane axial
  4. forward curved blade centrifugal
A
  1. forward curved blade centrifugal
30
Q

In most cases, what is the best fan to use on a blow pipe system for a sawmill ?

A

  1. cross flow fans
  2. axial fans
  3. vaneaxial fans
  4. propeller fans
A
  1. cross flow fans
36
