Question 1Plan Reading, Documentation and Reporting

A drawing is issued at a scale noted as 1/4" = 1'-0". What does this notation mean?

  1. four inches on the drawing equals one foot in the field
  2. one-quarter inch on the drawing equals one foot in the field Correct answer.
  3. one-quarter foot on the drawing equals one inch in the field
  4. the sheet has been reduced to one-quarter of its original size

Explanation

An architect's scale of 1/4 inch = 1 foot states the ratio between the printed drawing and the real building, so a quarter inch measured on the sheet represents twelve inches in the field. Equivalently, one inch on the sheet would represent four feet.

Question 2Plan Reading, Documentation and Reporting

Which information is normally found in the title block of a construction drawing sheet?

  1. The names of every subcontractor who bid on the work
  2. Project name, sheet number, and designer's seal Correct answer.
  3. The concrete supplier's mix design records
  4. The contractor's daily labor rates

Explanation

The title block identifies the sheet: project name and location, drawing title, sheet number, issue date, scale, and the seal and signature of the design professional responsible for it. It is the primary identification of the document.

Question 3Plan Reading, Documentation and Reporting

On a floor plan, a section cut is typically indicated by:

  1. a thin line with a small square at each end
  2. a light dotted line with a small triangle at each corner
  3. a dashed line with an arrow labeled "N"
  4. a heavy line with arrows and a section reference mark Correct answer.

Explanation

A section mark consists of a heavy cut line drawn through the plan with arrows showing the direction of view, plus a reference tag identifying the section drawing and the sheet on which it appears.

Question 4Plan Reading, Documentation and Reporting

An elevation drawing primarily shows:

  1. the exterior face of a building as seen from a straight-on view Correct answer.
  2. underground utilities and their invert elevations
  3. the relationship between floors shown in a vertical cut through the building
  4. the layout of rooms and partitions as seen from above

Explanation

An elevation is an orthographic projection of one face of the building viewed straight on, used to show heights, materials, and the location of windows and doors on that face.

Question 5Plan Reading, Documentation and Reporting

A wall measures 3 1/2 inches on a plan drawn at 1/8" = 1'-0". What is its actual length?

  1. 3 feet 6 inches
  2. 42 feet
  3. 14 feet
  4. 28 feet Correct answer.

Explanation

At a scale of 1/8 inch = 1 foot, each inch on the drawing represents 8 feet. Multiplying 3.5 inches by 8 feet per inch gives 28 feet.

Question 6Plan Reading, Documentation and Reporting

A door schedule on a set of drawings is used primarily to:

  1. indicate the sequence in which rooms are to be painted
  2. list each door with its size, type, hardware, and fire rating Correct answer.
  3. show the hourly fire-resistance rating of the building's structural frame
  4. record the dates on which doors were installed

Explanation

A door schedule is a table keyed to door marks on the plans, giving the size, type, frame and hardware set, and required fire rating for each opening. It is read together with the plan symbols.

Question 7Plan Reading, Documentation and Reporting

Column grid lines on a structural plan are used mainly to:

  1. show the property boundaries of the site
  2. mark the limits of the excavation contractor's work area on the site
  3. indicate the path of travel for the fire department
  4. locate structural elements and serve as a dimension reference Correct answer.

Explanation

Grid lines are reference lines, numbered in one direction and lettered in the other, to which columns, walls, and dimensions are tied so that all trades work from the same reference system.

Question 8Plan Reading, Documentation and Reporting

When reading a set of contract documents, the written specifications generally:

  1. are used only for bidding and have no role during construction
  2. repeat the dimensions shown on the drawings so they can be verified
  3. describe the quality and type of materials and workmanship Correct answer.
  4. take precedence only when they are printed after the drawings in the set

Explanation

Specifications are the written portion of the contract documents and govern the quality of materials, products, and workmanship. Drawings generally govern quantity, size, and location, and the two are read together.

Question 9Plan Reading, Documentation and Reporting

The north arrow on a site plan indicates:

  1. the direction of prevailing summer winds
  2. the building's orientation relative to true or assumed north Correct answer.
  3. the general direction that surface water drains across the lot
  4. the location of the nearest fire hydrant

Explanation

The north arrow establishes orientation so the plan can be related to the site and to other drawings. It may point to true north or to an assumed project north, which is usually stated in the notation.

Question 10Plan Reading, Documentation and Reporting

A request for information (RFI) is used during construction to:

  1. obtain clarification of the contract documents Correct answer.
  2. order a change to the contract sum
  3. submit a subcontractor's bid for approval
  4. notify the contractor in writing of a safety violation

Explanation

An RFI is a written question from the contractor to the design professional seeking interpretation or clarification of the contract documents, and the response becomes part of the project record.

Question 11Plan Reading, Documentation and Reporting

As-built (record) drawings are best described as:

  1. the drawings prepared by a fabricator for the components it will supply
  2. the original bid set issued for pricing
  3. the drawings that show only the building's structural system
  4. contract drawings marked up to show changes made in the field Correct answer.

Explanation

Record drawings begin as the contract documents and are marked by the contractor to reflect actual installed conditions, including dimensions, locations, and changes made during construction.

Question 12Plan Reading, Documentation and Reporting

A revision cloud drawn around an area of a plan indicates:

  1. a change made there since the previous issue of the drawing Correct answer.
  2. an area the contractor may value-engineer
  3. an area that will be constructed in a later phase of the project
  4. a portion of the work deleted from the contract

Explanation

Revision clouds, usually accompanied by a revision number or letter in a triangle or tag, mark the areas changed on a reissued sheet so the reader can compare it with the prior issue.

Question 13Plan Reading, Documentation and Reporting

A detail drawn at 1-1/2" = 1'-0" appears how many times larger than the same detail drawn at 3/4" = 1'-0"?

  1. The same size
  2. Half as large
  3. Twice as large Correct answer.
  4. Four times as large

Explanation

The first scale uses 1.5 inches per foot and the second uses 0.75 inch per foot. Dividing 1.5 by 0.75 gives 2, so the first detail is drawn twice as large as the second.

Question 14Plan Reading, Documentation and Reporting

Shop drawings differ from the design drawings in that shop drawings:

  1. replace the contract drawings once they are approved
  2. are prepared by the contractor to show fabrication details Correct answer.
  3. are prepared by the owner's architect to establish the design intent
  4. are used only for obtaining a building permit

Explanation

Shop drawings are prepared by the contractor, fabricator, or supplier to show how a product will be made and installed, and the designer reviews them for conformance with the design concept.

Question 15Plan Reading, Documentation and Reporting

A detail callout on a floor plan, such as a circle with a detail number and a sheet reference beneath it, tells the reader:

  1. the cost code assigned to that portion of the work
  2. how many copies of the detail are required
  3. where the enlarged detail can be found in the set Correct answer.
  4. the date on which that portion of the work was designed

Explanation

A detail callout is a cross-reference: the top number identifies the detail and the bottom number identifies the sheet on which the enlarged view is drawn, allowing the reader to navigate the set.

Question 16Plan Reading, Documentation and Reporting

A contractor's daily report typically records:

  1. the approved contract sum and the amount of retainage held
  2. the owner's financing schedule
  3. the designer's structural calculations
  4. weather, workforce, equipment, and work performed Correct answer.

Explanation

The daily report is the contractor's contemporaneous record of site conditions and resources - weather, manpower, equipment, deliveries, and work accomplished. It supports progress reporting and later delay or change claims.

Question 17Plan Reading, Documentation and Reporting

A change order is a document that:

  1. lists the items the contractor considers incomplete at substantial completion
  2. authorizes a subcontractor to begin work before the contract is signed
  3. records a verbal instruction given at the job site by the inspector
  4. formally modifies the contract amount, time, or scope Correct answer.

Explanation

A change order is a written modification to the contract, signed by the owner and the contractor, adjusting the contract sum, the contract time, or the scope of work.

Question 18Plan Reading, Documentation and Reporting

A drawing legend on a sheet is used to:

  1. list the names of the firms that prepared the drawings
  2. explain the symbols and abbreviations used on that sheet Correct answer.
  3. give the legal description of the property
  4. record the dates the drawings were delivered to the printer

Explanation

The legend, usually placed near the title block or in a corner of the sheet, defines the graphic symbols, line types, hatching, and abbreviations so the sheet can be read consistently.

Question 19Plan Reading, Documentation and Reporting

On a grading plan, contour lines that are spaced closely together indicate:

  1. the edge of the property line
  2. a steep slope Correct answer.
  3. a nearly level area
  4. an area of undisturbed vegetation

Explanation

Contour lines connect points of equal elevation. Where they are close together, elevation changes rapidly over a short horizontal distance, which is a steep slope; widely spaced contours indicate nearly flat ground.

Question 20Plan Reading, Documentation and Reporting

A benchmark shown on a site plan as 112.35 indicates:

  1. the distance from the street to the building is 112.35 feet
  2. the site contains 112.35 cubic yards of fill
  3. a point whose elevation is 112.35 feet above the datum Correct answer.
  4. the building's maximum permitted height is 112.35 feet

Explanation

A benchmark is a fixed reference point of known elevation, and the number shown is its elevation above the datum adopted for the project. All site and foundation elevations are measured from it.

Question 21Plan Reading, Documentation and Reporting

Minutes of a preconstruction meeting are important because they:

  1. replace the need for a written contract between the parties
  2. serve as the contractor's application for payment
  3. create a written record of decisions and instructions Correct answer.
  4. are required to be notarized before construction begins

Explanation

Minutes provide a contemporaneous written record of what was discussed, decided, and instructed, and they are commonly relied on to resolve later disagreement about what the parties agreed.

Question 22Plan Reading, Documentation and Reporting

In a typical drawing set, a sheet numbered A-201 would most likely be:

  1. a plumbing riser diagram
  2. an architectural sheet in the 200 series Correct answer.
  3. a structural foundation plan
  4. a civil site utility plan

Explanation

Sheet numbers usually combine a discipline letter with a series number: A for architectural, S for structural, M for mechanical, E for electrical, P for plumbing, and C for civil. A-201 is therefore an architectural sheet in the 200 series.

Question 23Plan Reading, Documentation and Reporting

On a plan, dimensions are commonly shown as strings of figures taken to:

  1. the outside face of the foundation wall and nothing else
  2. reference lines such as column grids or wall faces Correct answer.
  3. the center of the nearest column only
  4. the nearest property corner

Explanation

Dimensions are tied to established reference lines - column grid lines, wall faces, or established building lines - so that every trade works from the same references and figures can be checked from more than one direction.

Question 24Plan Reading, Documentation and Reporting

When a discrepancy is found between a large-scale detail and a small-scale plan of the same condition, the usual convention is that:

  1. the discrepancy is resolved by the building official at final inspection
  2. the large-scale detail governs because it is more precise Correct answer.
  3. the small-scale plan governs because it shows the whole building
  4. the contractor may choose whichever is less costly

Explanation

The customary rule of interpretation is that the more specific, larger-scale document controls over the more general one, so an enlarged detail governs over a small-scale plan of the same condition.

Question 25Plan Reading, Documentation and Reporting

A record photograph taken to document a concealed condition is most useful when the image includes:

  1. only the inspector's handwritten note on the back of the print
  2. a wide-angle view taken from the farthest corner of the site
  3. the contractor's signature applied to the image file
  4. a date and a scale reference such as a tape measure or ruler Correct answer.

Explanation

A useful record photograph ties the image to a time and a scale, so the size and location of the documented condition can be established later without relying on memory.

Question 26Plan Reading, Documentation and Reporting

In a typical drawing set, the letter prefix in a sheet number such as FP-301 identifies the:

  1. revision number of the sheet
  2. discipline or drawing series Correct answer.
  3. phase of the project schedule
  4. sheet size and issue date

Explanation

Sheet numbers are built from a discipline letter or series code followed by a sequential number, so the prefix groups sheets by trade or system such as architectural, fire protection, or electrical. The number after the hyphen identifies the individual sheet, not its size, revision, or schedule status.

Question 27Plan Reading, Documentation and Reporting

A label reading "R-2" placed inside an area on a life safety plan most likely designates the:

  1. occupancy classification Correct answer.
  2. fire district designation
  3. sprinkler design density
  4. construction type

Explanation

Occupancy groups are commonly annotated on life safety plans using the code's group designation, and R-2 identifies a residential occupancy of the type covered by that group. Construction type is shown with a separate notation such as Type V-B, and densities and districts use different formats.

Question 28Plan Reading, Documentation and Reporting

A wall measures 3 inches on a plan drawn at 1/8 inch = 1 foot. What is the actual length of that wall?

  1. 32 feet
  2. 12 feet
  3. 24 feet Correct answer.
  4. 8 feet

Explanation

At a scale of 1/8 inch per foot, each 1/8 inch on the drawing represents 1 foot in reality, so the number of eighths of an inch equals the number of feet. Three inches contains 24 eighths, so the wall is 24 feet long.

Question 29Plan Reading, Documentation and Reporting

On a floor plan, a small filled triangle identified by the letters FE most commonly indicates a:

  1. fire alarm pull station
  2. fire department connection
  3. floor drain
  4. portable fire extinguisher cabinet Correct answer.

Explanation

Fire protection symbols are keyed to the sheet legend, and the letters FE conventionally stand for fire extinguisher, with a small symbol marking the cabinet location. Pull stations, drains, and connections each have their own distinct symbols and abbreviations.

Question 30Plan Reading, Documentation and Reporting

A fire sprinkler riser diagram on a permit set primarily shows:

  1. the manufacturer's product data sheets
  2. the hydraulic calculations for the system
  3. a schematic of piping, sizes, and components, not drawn to scale Correct answer.
  4. the exact physical routing of every pipe at plan scale

Explanation

Riser diagrams are single-line schematics that show how water travels from the supply through valves, alarms, and piping to the heads, with sizes and components labeled. They are not dimensioned to scale and do not replace plan views, calculations, or product literature.

Question 31Plan Reading, Documentation and Reporting

The specific edition of the building and fire codes that governs a project is normally identified:

  1. on the site plan next to the benchmark
  2. in the structural calculations
  3. in the door and window schedules
  4. on the cover sheet or in the general notes Correct answer.

Explanation

The code edition, along with any local amendments, is stated on the cover sheet or in the general notes so that every reviewer and inspector applies the same requirements. Schedules, site plans, and calculations serve other purposes and do not establish the governing code.

Question 32Plan Reading, Documentation and Reporting

A certificate of occupancy is issued to:

  1. confirm that the building may be occupied for its intended use Correct answer.
  2. confirm that the design professional's license is current
  3. certify that the contractor has been paid in full
  4. record the date the building permit was issued

Explanation

A certificate of occupancy confirms that the completed building has been inspected and complies with the code for the occupancy and use stated on the document. It is a legal prerequisite to occupancy and is not a financial, licensing, or permit-dating record.

Question 33Plan Reading, Documentation and Reporting

A transmittal accompanying a submittal primarily:

  1. documents the fire inspector's field observations
  2. records what is being sent, to whom, and on what date Correct answer.
  3. serves as the contractor's request for information
  4. authorizes payment for the work covered

Explanation

A transmittal is a routing record that identifies the documents sent, the recipients, and the date, creating a written trail for the project file. It does not approve payment, ask technical questions, or record inspection findings.

Question 34Plan Reading, Documentation and Reporting

Exit access travel distance shown on a life safety plan is measured:

  1. from the farthest point to the nearest sprinkler head
  2. along the actual path a person would walk to reach an exit Correct answer.
  3. as a straight line from the farthest point to the exit
  4. along the corridor centerline only

Explanation

Travel distance is measured along the route of travel, following the geometry of the space, corridors, and aisles rather than a straight line. Measuring along the actual path accounts for obstructions and changes in direction that a building occupant would encounter.

Question 35Plan Reading, Documentation and Reporting

A wall on a floor plan is drawn with a distinctive line type and tagged 2HR. The tag indicates that the wall is a:

  1. smoke partition with no fire rating
  2. two-hour fire flow area
  3. two-inch water supply line
  4. fire-resistance-rated assembly of two hours Correct answer.

Explanation

Wall tags state the fire-resistance rating of the assembly in hours, and the line type or hatch reinforces that the wall is a rated barrier. The rating establishes the protection required for the assembly and the openings within it.

Question 36Plan Reading, Documentation and Reporting

A door schedule lists a 36-inch door leaf installed in a standard frame with stops. The clear egress width of the opening in the open position is approximately:

  1. 34 inches
  2. 28 inches
  3. 32 inches Correct answer.
  4. 36 inches

Explanation

Clear width is measured between the face of the door leaf in the open position and the stop on the strike jamb, so it is less than the nominal leaf width. A 36-inch leaf typically yields about 32 inches of clear width once the frame stop and hinge offset are deducted.

Question 37Plan Reading, Documentation and Reporting

On a site plan, the fire department connection is required to be located:

  1. within the required distance of a hydrant and accessible to fire crews Correct answer.
  2. at the property line farthest from the building
  3. on the roof adjacent to the standpipe
  4. inside the fire pump room only

Explanation

Codes require the fire department connection to be placed where responding crews can reach it and connect hose lines, typically within a specified distance of a hydrant and clear of obstructions. Placement is judged on accessibility, not on distance from the property line or convenience of the piping.

Question 38Plan Reading, Documentation and Reporting

The required spacing of fire hydrants around a new building is determined primarily by:

  1. the distance between adjacent property corners
  2. the plumbing fixture count of the building
  3. the size of the water meter serving the building
  4. the required fire flow and the code's spacing and access provisions Correct answer.

Explanation

Hydrant spacing is set by the adopted fire code based on the fire flow needed for the building and the distance and access requirements for apparatus. Fixture counts, property geometry, and meter size do not establish the spacing requirement.

Question 39Plan Reading, Documentation and Reporting

After completing a plan review, a correction notice listing deficiencies is used to:

  1. approve the plans with no further action required
  2. serve as the permit to begin construction
  3. identify each deficiency that must be corrected before approval Correct answer.
  4. replace the approved plans in the field

Explanation

A correction notice documents the specific code items that must be resolved and typically requires the designer to revise and resubmit the affected sheets. It is not an approval, a permit, or a field set of drawings.

Question 40Plan Reading, Documentation and Reporting

A submittal log maintained by the contractor is used to:

  1. show the sequence of construction trades on site
  2. record the inspection results for each floor
  3. list the code sections that apply to the project
  4. track the status and due dates of required submittals Correct answer.

Explanation

The submittal log is a register of every required submittal with its number, description, dates submitted and returned, and current review status. It supports scheduling and closeout by showing which items remain outstanding.

Question 41Plan Reading, Documentation and Reporting

An inspection report should be written so that it:

  1. is prepared only for the inspector's personal records
  2. relies on general impressions rather than specific findings
  3. can be understood by someone who was not present at the inspection Correct answer.
  4. records only the items that passed inspection

Explanation

An inspection report is a permanent record that may be read later by supervisors, attorneys, or a court, so it must stand on its own with dates, locations, observations, and code references. Vague impressions or selective reporting weaken its evidentiary value.

Question 42Plan Reading, Documentation and Reporting

A notation of Type II-B on a cover sheet describes a building that is:

  1. combustible with a one-hour structural rating
  2. heavy timber construction throughout
  3. noncombustible with a two-hour rating on all members
  4. noncombustible with unprotected structural members Correct answer.

Explanation

In the standard construction type classification, Type II construction is noncombustible, and the B suffix indicates that the structural elements are not required to have a fire-resistance rating. The A suffix would denote protected noncombustible construction with rated members.

Question 43Plan Reading, Documentation and Reporting

On a fire alarm plan, the abbreviation SD placed inside a symbol typically denotes a:

  1. strobe device
  2. speaker duct
  3. smoke detector Correct answer.
  4. sprinkler drop

Explanation

Fire alarm plans use a legend of abbreviations for devices, and SD conventionally means smoke detector. Other devices carry their own abbreviations, such as HD for heat detector or PS for pull station.

Question 44Plan Reading, Documentation and Reporting

On a life safety plan, exit signs are typically shown at:

  1. the main electrical room and the fire command center
  2. the ends of dead-end corridors only
  3. each exit and at points where the path of egress is not obvious Correct answer.
  4. every sprinkler riser location

Explanation

Exit signage must be visible at every required exit and wherever the direction of egress travel is not readily apparent to occupants. Signs are not tied to sprinkler risers, limited to dead ends, or confined to electrical and command spaces.

Question 45Plan Reading, Documentation and Reporting

The required fire flow for a new building is most directly determined by:

  1. the distance to the nearest fire station
  2. the construction type, area, and occupancy of the building Correct answer.
  3. the building's occupant load and egress width
  4. the number of sprinkler heads on the largest branch line

Explanation

Fire flow tables base the needed water supply on the construction classification, the fire area, and the occupancy, with reductions permitted for sprinkler protection. Occupant load and head counts do not enter the fire flow calculation.

Question 46Plan Reading, Documentation and Reporting

A hydraulic design placard for a sprinkler system is required to be:

  1. printed on the building's certificate of occupancy
  2. attached at the riser, showing design density, area, and pressures Correct answer.
  3. placed inside the fire alarm control panel enclosure
  4. filed in the owner's maintenance office in a binder

Explanation

The placard must be permanently attached at the riser so that anyone working on or evaluating the system can see the design density, protected area, and required pressures at a glance. Keeping it in an office file or another enclosure would not satisfy the posting requirement.

Question 47Plan Reading, Documentation and Reporting

A Record of Completion for a fire alarm system documents:

  1. the installed configuration and acceptance test results Correct answer.
  2. the manufacturer's warranty for each device
  3. the contractor's original bid for the system
  4. the fire department's pre-incident plan for the building

Explanation

The Record of Completion captures how the system was actually installed and how it performed during acceptance testing, and it is signed by the installing contractor and the owner's representative. It is the document that shows the system matches its approved design.

Question 48Plan Reading, Documentation and Reporting

An addendum issued during the bidding phase is:

  1. a substitute for the contractor's shop drawings
  2. a clarification issued only after construction begins
  3. a modification to the bidding documents that becomes contractual Correct answer.
  4. an informal note with no contractual effect

Explanation

An addendum modifies or clarifies the bidding and contract documents before bids are opened, and it becomes part of the contract when issued in accordance with the instructions to bidders. Bidders are typically required to acknowledge each addendum in their proposal.

Question 49Plan Reading, Documentation and Reporting

When a material sample is collected for laboratory testing, chain-of-custody documentation must:

  1. be required only when the sample is hazardous
  2. be kept solely by the testing laboratory
  3. record each transfer of the sample from collection through testing Correct answer.
  4. be completed after the test results are known

Explanation

Chain of custody creates an unbroken written record of who possessed the sample, when, and under what conditions, so that the test results can be relied on as authentic. The record begins at collection and follows the sample through every handoff to the laboratory.

Question 50Plan Reading, Documentation and Reporting

A deferred submittal is best described as:

  1. a submittal the contractor is permitted to skip entirely
  2. a work item listed in the contract documents for later submission Correct answer.
  3. a request to postpone an inspection to a later shift
  4. a revised sheet issued to replace an entire drawing

Explanation

Certain items, such as pre-engineered components or specialized systems, are identified in the contract documents as deferred submittals and are reviewed after the permit is issued on a stated schedule. They remain required submissions and do not excuse the contractor from providing them.
