PDD ARE 5.0 Project Development and Documentation Exam Question and Answers

At 50% CDs with early PEMB coordination and compressed schedule, typical cross-discipline clashes in corridors involve above-ceiling valves/dampers that lack required access from a public space. Plumbing and mechanical codes require accessible, labeled access panels for isolation/shut-off valves (and similar devices) located in concealed spaces so they can be serviced without disrupting operations—critical here because farm work must continue during construction/operation.

Exit sign at door #15 (A) depends on egress analysis; not a generic coordination issue.

Relocate diffusers (B) is a comfort/layout decision, not a compliance coordination issue unless they conflict with lights/sprinklers.

The question is about the relative section modulus (S) required for a glue-laminated beam vs. a sawn timber beam to resist the same bending moment. The formula relating bending stress (Fb), moment (M), and section modulus (S) is:

For the same bending moment M, the section modulus is inversely proportional to the allowable bending stress

Therefore, the glue-laminated beam requires half the section modulus compared to the sawn timber beam.

From the exhibit, the existing wall has a total thermal resistance R = 4.12.

Overall heat transmission (U-value) is U = 1/R = 1/4.12 ≈ 0.24, which matches the figure.

If unfaced R‑19 batt insulation is added in the stud cavity, the total resistance increases by 19:

In wood selection for exterior construction, certain species’ heartwoods contain natural extractives/resins that deter decay and insect activity. Western Red Cedar and Cypress are well known for natural durability and termite resistance without chemical treatment. Species such as Douglas fir, hemlock, southern yellow pine, and most oaks are not reliably termite‑resistant in their sapwood and typically require preservative treatment for use in termite zones.

For historic masonry rehabilitation, the accepted approach (e.g., NPS Preservation Brief 2: Repointing Mortar Joints in Historic Masonry) is to hand‑rake deteriorated mortar to a proper depth (typically 2–2½× the joint width or until sound mortar is reached), avoid power‑saw removal that can damage historic brick, and match the original mortar in composition, hardness, color, and tooling.

A is incorrect because removing all mortar for a “uniform appearance” is unnecessary and risks damaging sound joints.

B is incorrect because electric saws can chip and over‑cut historic brick arrises, violating preservation best practices.

C is correct: careful hand removal of loose/deteriorated mortar followed by repointing with compatible mortar is the recommended method.

In concrete technology, admixtures are used to modify properties of fresh or hardened concrete:

Air-entraining agents: Introduce microscopic air bubbles to improve freeze-thaw resistance; they do not increase slump.

Water-reducing agents: Reduce water content while maintaining slump; increase workability but only moderately.

Calcium chloride: An accelerator, speeds up setting time; does not increase slump.

Superplasticizers (also called high-range water reducers): Significantly increase the slump (workability) of concrete without adding extra water, making the mix more flowable and easier to place.

Thus, to greatly increase slump while maintaining water-cement ratio, the superplasticizer is the correct choice.

In cold climates, the vapor drive is from the warm interior to the cold exterior during winter. The vapor retarder/barrier belongs on the warm-in-winter side of the assembly—i.e., behind the interior gypsum, before the framing/insulation—to prevent interior moisture from reaching cold layers where it could condense.

PDD references: Psychrometrics & vapor drive; vapor retarder placement (ASHRAE; IBC/IECC guidance; ARE 5.0 PDD—Thermal & Moisture Protection).

The upper nut at the top connection in Option 2 (the nut above the upper tube beam, highlighted at left).

By moving the threaded rod off the member’s centroid in Option 2, the connection becomes eccentric. That eccentricity introduces a prying/bending moment at the rod/beam interface in addition to the vertical load from the banner and beam. In a through‑rod with a nut above and below the member, the bottom nut primarily resists the direct gravity load in the concentric case (Option 1). When eccentricity is added (Option 2), rotation of the member about the rod induces additional uplift on the top nut (prying action), thereby increasing the force in the top nut relative to the concentric case.

Hence, the nut that will realize the greater load due to the proposed change is the upper nut at the top connection.

Cutting holes in beam webs is common for running mechanical, electrical, or plumbing services but must be done carefully to avoid weakening structural integrity.

Holes should be located near mid-span supports (points of low bending moment and high shear) to reduce impact on beam bending strength.

Holes should not be located near areas of maximum bending moment (typically mid-span between supports), because this is where the beam experiences maximum tension or compression.

Locations 2 and 4 are at or near the beam supports (shear zones), and generally small holes can be cut there, following size limits and reinforcement guidelines.

Locations 1, 3, and 5 are closer to mid-span or areas of high bending stress, so holes here risk compromising the beam’s moment capacity.

Understanding the Context

The addition of a 4'-0" x 4'-0" storage closet accessible from the corridor is a design scope modification. Even though this might appear minor, in the context of a Design-Build project delivery method, any change in the scope or spatial layout directly impacts the contract documents. Since the delivery model combines design and construction responsibilities under a single entity, accuracy and clarity in the Owner-Contractor Agreements (AIA A101, A102, or A103) is critical.

Why A101, A102, and A103 Require Revisions

A101 – Standard Form of Agreement Between Owner and Contractor (Stipulated Sum):This document defines the scope, cost, and responsibilities of the contractor. Adding a storage closet may alter construction cost, schedule, or scope, which must be formally revised and incorporated via an amendment or change order.

A102 – Standard Form of Agreement Between Owner and Contractor (Cost of the Work Plus a Fee with GMP):Similar to A101, but applies to projects with a Guaranteed Maximum Price (GMP). The addition of new work, even small, may affect the GMP or contingency usage. Therefore, it also requires formal documentation of the scope change.

A103 – Standard Form of Agreement Between Owner and Contractor (Cost of the Work Plus a Fee without a GMP):Again, even though no GMP is involved, changes to project scope must be documented for cost tracking and accountability.

According to NCARB ARE 5.0 PDD Handbook – Section: Project Manual and Contract Documents:

“The architect must evaluate how any proposed revisions to the work affect the project’s scope, schedule, and budget. These revisions must be incorporated into the contract documents and may require issuing an amendment or modification to the contract.”

Furthermore, under Objective 4.2 – Evaluate and address changes in scope of work and scope creep, ARE candidates are expected to know when and how revisions impact contract documents.

In design-build delivery, all these contract forms must reflect any changes, even minor ones, because the contractor holds responsibility for both design and construction execution. Failure to reflect the change may lead to contractual disputes or unaccounted costs.

Why Other Options Do Not Apply

D. Building Systems Narrative:This narrative typically outlines the design intent and basis for HVAC, electrical, and plumbing systems. A minor storage closet accessed from a corridor would not alter system layout or equipment sizing, and thus doesn't necessitate a revision to this document.

E. Initial Cost Estimate:While the estimate may eventually need updating during cost reconciliation, the question specifically asks which documents require revision. The initial estimate is a schematic-level document that doesn’t necessarily need to be revised for such a minor addition.

F. Specification Excerpts:Unless the closet introduces new materials (e.g., special finishes, fire-resistive construction, unique fixtures), the specifications remain unchanged. The closet is likely using standard finishes already defined elsewhere in the spec.

Sheet piling is a type of earth retention system used in excavations to prevent soil collapse. Reasons include:

D. When the natural soil slope is too steep to remain stable, sheet piling acts as a vertical barrier.

E. When soil cannot support itself during excavation, sheet piles provide lateral support.

F. When excavation is adjacent to a property line or existing structure and adjacent soil must not be disturbed.

Options A (grade beam support), B (raked shoring), and C (pile cap support) are not typical or primary uses of sheet piling.

In NCARB ARE 5.0 PDD, balconies are considered part of the building envelope and exterior assembly, requiring coordination between structural, architectural, and sometimes MEP elements. The project manual's specification sections for balconies should include all components integral to the balcony's construction and performance — not unrelated furnishings or general door types unless they are directly part of the balcony system.

Reasoning for each selection:

A. Drainage — REQUIRED:

Balconies must include drainage provisions to prevent standing water, freeze-thaw damage, and leakage into units. This is part of Division 07 (Thermal and Moisture Protection) in the CSI MasterFormat and directly tied to durability and code requirements.

B. Floor finish coating — REQUIRED:

The balcony surface finish must be specified for slip resistance, durability, weather resistance, and integration with waterproofing membranes. This is usually in Division 09 (Finishes) but referenced in Division 07 for waterproof coatings.

E. Guardrail anchoring — REQUIRED:

Structural anchorage details for the glass guardrail parapets must be specified to meet IBC load requirements (200 lb concentrated load per IBC 1607.8) and to ensure safety. This falls under Division 05 (Metals) or Division 05/08 integration.

F. Glazing system — REQUIRED:

Glass guardrails involve tempered or laminated safety glazing per IBC Chapter 24 and must be specified, including thickness, type, finish, and installation method.

Why the others are excluded:

C. Furnishings — NOT REQUIRED: Balconies may have furniture, but these are FF&E, not part of the construction scope in the balcony specification.

D. Door types — NOT REQUIRED: Doors leading to balconies are part of the exterior wall fenestration package, not the balcony construction section.

Glycol-cooled air conditioning systems use a glycol-water mixture as a secondary coolant instead of plain water. Glycol has lower freezing point and better heat transfer properties in certain conditions.

Advantages include:

Longer piping runs without freezing risk, allowing the chiller or cooling unit to be located further away from the computer room, useful for flexible building layouts.

Glycol prevents freezing in cold climates or exposed pipes.

It does not inherently reduce heat exhausted or is necessarily more sustainable than water cooling.

Glycol is generally more expensive than water.

Therefore, the primary advantage is the ability to locate the cooling unit farther from the space being cooled.

IBC governs occupancy classification, occupant loads, and required means of egress. A 300-person taproom triggers egress path requirements under IBC Chapter 10. Objective 1.3 addresses code compliance.

1. Problem Summary

Goal: Reduce reverberation time (RT) in the Tap Room to 2.0 seconds or less.

Current design: 2' x 2' acoustic ceiling tile system (RT = 2.0 seconds) installed above fans.

Constraint: Minimize additional project cost.

Recommendation from acoustical engineer: Use materials to achieve target RT without redesigning the space.

3. Interpretation of RT Values

Current 2x2 Acoustic Ceiling Tile: RT = 2.0 seconds → meets the target exactly.

However, fans may reduce the acoustic performance by reflecting or scattering sound, so supplemental absorption may be needed.

Adding Acoustical Sound Board (RT = 1.6) above the existing tile system will improve absorption and lower RT below 2.0 seconds.

4. Cost & Constructability

Retaining the current ceiling layout and simply adding a layer above is:

Least disruptive to current design.

Avoids redesign of the ceiling cloud layout.

Minimizes schedule impact (critical for design-build with compressed schedule).

Replacing with wood fiber panels (1" or 2") would require removal of existing tile, redesign of suspension, and higher cost/SF.

5. Why Other Options Are Incorrect

A. Remove fans: This addresses air movement, not RT. Removing them does not guarantee RT improvement and conflicts with HVAC design intent.

B. One cloud + 1" wood fiber panels: Reduces coverage area and may not meet RT goal; also costly and disruptive.

C. One cloud + 2" wood fiber panels: Even more costly, same redesign problem as B.

D. Retain tiles and add sound board above: Achieves RT < 2.0, minimal disruption, cost-effective vs. full replacement → best option.

Converting two existing 2-bedroom units into two 1-bedroom units each yields two additional dwelling units total, while keeping every unit on an exterior wall for light/vent and maintaining typical plumbing stacks/egress.

A introduces two studios (size/layout risk) and alters a lower-floor stack; more coordination risk.

C converts a Laundry (likely interior and serving the building) into a unit—problematic for light/ventilation and building services.

Understanding the Diagram

The detail shows a fan coil unit suspended from the structure, with:

Vibration isolators at the hanging rods to limit mechanical vibration transfer to the structure.

Flexible duct connections between the fan coil unit and the rigid ductwork.

Purpose of Flexible Duct Connections

Flexible connections in HVAC duct systems are designed to:

Prevent transmission of vibration and sound from the mechanical equipment (fan coil unit) into the rigid ductwork and building.

Compensate for small misalignments between the ductwork and equipment.

Accommodate minor thermal expansion/contraction movements.

Key Function in This Context:

Fan coil units contain fans that create vibration and noise. Without a flexible connection, this vibration would travel directly through the rigid ductwork into occupied spaces, increasing noise levels.

Why Other Options Are Incorrect:

A. To provide a field point of connection — While the flexible connector does connect ducts, its purpose is not just convenience; it is specifically for vibration/sound isolation.

B. To insulate against heat transfer — This is done with thermal duct insulation, not flexible connectors.

D. To transition from flange to desired duct size — Transitions are made using sheet metal fittings, not flexible connectors.

Sources:

Mechanical and Electrical Equipment for Buildings (MEEB) — Vibration Control in Mechanical Systems

Key Point:

Flexible connectors in ductwork break the direct mechanical path for vibration and sound, reducing noise transfer from fans to occupied areas.

Control joints in concrete masonry walls are designed to accommodate movement caused by thermal expansion, moisture changes, and settlement.

Control joints should be placed at locations of stress concentration, such as changes in wall height, changes in wall thickness, or at large wall expanses.

They are not placed at the first course of masonry (which is typically reinforced and anchored to the foundation).

They are generally not placed at window corners or in the center of window openings but rather at planned intervals or changes in geometry.

Placing a control joint at changes in wall height allows movement without cracking.

Selecting trees for residential streets near a new development should prioritize:

Adaptability to local climate and soil conditions to ensure healthy growth and longevity.

While seasonal foliage, color, scale, and wildlife habitat are important, they are secondary to ensuring the tree can survive and thrive in the environment.

Dense root systems and wind resistance are considerations but often come after adaptability is confirmed.

Designing a barrier-free (accessible) building entrance requires coordination among:

Door schedule: Door sizes, types, clearances, and thresholds

Hardware schedule: Handles, closers, locks, and accessibility hardware (e.g., lever handles, automatic operators)

Alarm system design: To ensure audible and visual alarms meet ADA requirements for people with disabilities, particularly for emergency egress

Other documents like electrical and structural plans are important but less directly related to barrier-free entrance compliance.

When a GMP (Guaranteed Maximum Price) is established before the design is 100% complete and specific materials are not yet chosen, the correct approach is to specify allowances in the project manual.

An allowance is a fixed monetary amount for a specific scope item (e.g., flooring finishes) that allows the contractor to carry a cost in the bid/GMP until the actual product is selected. This ensures the GMP covers the item without delaying pricing.

A. Contingency — Is for unforeseen conditions, not specific unselected finishes.

B. Schedule of unit prices — Typically used for variable-quantity work, not for unknown product selection.

D. Alternate — Provides an option for substitution, but does not guarantee a base cost in the GMP.

The transformer is located in the first large box after the high-voltage primary feeders and before the secondary service conductors on the left side of the diagram.

Step-by-Step Reasoning

1. Understanding the diagram flow:

The leftmost symbol represents high-voltage primary feeders from the utility (2,400V, 4,160V, 7,200V, or 13,200V).

Immediately after that, there is a large box labeled "Secondary Service conductors" with standard building service voltages (120/208, 120/240, 277/480 V).

To get from primary (medium/high) voltage to these usable secondary voltages, you must step down the voltage — and that is done by a transformer.

2. Transformer location in electrical distribution:

Transformers are always placed between the incoming primary service and the secondary distribution system in building diagrams.

In this drawing, the transformer is symbolized by the first large square/rectangular box after the high-voltage primary feeders.

3. Why not any other box?

The following boxes and lines after this first step are feeders, panels, and motor starters — they operate at secondary voltage.

Only the transformer connects the utility high-voltage system to the building's lower-voltage system.

Architectural Graphic Standards — Single-Line Diagrams for Electrical Distribution

Key Point:

In building electrical distribution, the transformer is always between the high-voltage primary service and the secondary service conductors to step down voltage to a usable level for building loads.

To prepare project specifications, the architect requires documents that inform about site conditions, building construction, and interior finishes:

Geotechnical report provides soil conditions, foundation recommendations, and site constraints.

Building sections provide detailed information on assemblies, materials, and vertical relationships.

Room finish schedule identifies finishes, materials, and related specifications for interior spaces.

Legal surveys, traffic management plans, and door schedules are important for planning and design coordination but less directly informative for writing specifications.

This question relates to ADA (Americans with Disabilities Act) minimum clear width requirements for hallways or corridors when doors swing into the corridor, affecting the clear width.

ADA Minimum Clear Width Requirements for Corridors with Door Swing:

According to the 2010 ADA Standards for Accessible Design and the relevant NCARB ARE 5.0 PDD study materials referencing accessibility requirements:

The minimum clear width of a hallway or corridor without any door swing interference is 36 inches (3 ft).

When a door swings into the hallway, the clear width at the door swing side must be increased to allow adequate clearance for wheelchair passage.

The required clear width is the sum of:

The minimum clear width of the hallway (36 inches), plus

The depth of the door swing into the hallway, minus 2 inches.

Formula:

Clear width with door swing = 36 inches + Door swing depth - 2 inches

Given:

Door swing dimension (B) = 4 inches

Minimum clear width without door swing = 36 inches

Calculate minimum hallway width:

Clear width = 36 in + 4 in - 2 in = 38 inches (3 ft 2 in)

But notice:

The exhibit shows the door swing with a 3 ft dimension noted (likely the door width or the door clearance), and the question asks for minimum dimension of Hallway A to meet ADA, taking into account the 4 in door swing (B).

According to NCARB ARE 5.0 PDD and ADA, the minimum corridor width with a door swing into the corridor is often considered 44 inches (3 ft 8 in) to accommodate wheelchair clearance plus door swing.

This is because:

The standard minimum clear width of 36 inches is for an unobstructed corridor.

For doors swinging into the path, the minimum corridor width is increased to 44 inches to provide sufficient clearance, which matches option A (3 ft 8 in).

Supporting Reference:

NCARB ARE 5.0 Review Manual, Project Development and Documentation, Accessibility Chapter

2010 ADA Standards, Section 404.2.4 Corridor Widths

The rule is that when a door swings into a corridor, the corridor must be at least 44 inches wide, allowing 36 inches for passage and an additional 8 inches for door swing and maneuvering clearance.

Summary:

Minimum corridor width without obstruction = 36 inches (3 ft)

With door swing (4 in), increase to 44 inches (3 ft 8 in) minimum to maintain clear passage for wheelchair users.

Green roofing adds significant dead loads due to soil and water retention layers. Structural engineers must verify load-bearing capacity. This is tied to ARE Objective 3.2 on evaluating integration of building systems.

1. Understanding the APA Grade Stamp

The stamp in the exhibit reads:

APA RATED SHEATHING 32/16

15/32 INCH (thickness)

SIZED FOR SPACING

EXPOSURE 1 (can handle temporary moisture exposure)

2. Meaning of "32/16"

The numbers 32/16 are the span ratings for the panel:

32 inches = maximum recommended span for roof sheathing (when applied perpendicular to supports).

16 inches = maximum recommended span for floor sheathing (when applied perpendicular to supports).

These ratings are established by APA (The Engineered Wood Association) based on panel thickness, grade, and allowable loads/deflection limits.

3. Applying to the Question

The question asks specifically for maximum recommended span for use in a floor system.

From the stamp:

Floor span rating = 16 inches

Therefore, the correct answer is 16 in.

4. Why Other Options Are Incorrect:

A. 15 in — Not the value given; 16 in is the rating.

C. 32 in — This is for roof applications, not floor systems.

D. 108 in — Not related to APA span ratings; possibly confused with the certification number "NBR-108."

The diagram shows a basement foundation wall below the water table. During heavy rains, the water table can rise, increasing hydrostatic pressure against foundation walls and under the slab.

Key concern:

While lateral water pressure against the walls is a factor, the question specifies "also a major concern". In this scenario, the water pressure beneath the slab can cause buoyant uplift — vertical upward pressure — known as hydrostatic uplift or floatation.

If this upward force exceeds the weight of the slab and the structure above, it can cause the slab to crack, lift, or fail — especially if there is no adequate under-slab drainage or tiedown anchors.

Why not the other options:

A. Moisture absorption of the concrete foundation wall — Concrete is porous, but waterproofing and drainage address this; not as critical in terms of structural threat as uplift.

B. Increased weight on the footings — Hydrostatic pressure acts laterally and upward; it does not significantly increase vertical load on footings in the same way dead load does.

D. Differential lateral pressure on total building structure — Lateral pressure affects the foundation walls, but "total building structure" is less directly impacted than the immediate risk to the slab from uplift.
