NCARB PDD Exam Questions
- Topic 1: Integration of Building Materials & Systems: This section of the exam measures the skills of Architectural Designers and focuses on the ability to resolve and integrate various building systems into cohesive project goals. It covers analyzing architectural systems and technologies, determining the size of structural, mechanical, electrical, and plumbing systems, and incorporating specialty systems such as acoustics, lighting, security, and communications. It also evaluates the ability to detail how multiple building systems work together and to coordinate across disciplines to achieve a unified design.
- Topic 2: Construction Documentation: This section of the exam measures skills of Project Architects and addresses the creation and management of project documentation. Candidates are expected to demonstrate knowledge of documenting building design and site features, preparing detailed architectural drawings, and applying industry standards to produce a coordinated set of construction documents. The section also includes understanding how project changes impact documentation and how to communicate these updates effectively to both the design team and the client.: Project Manual & Specifications: This section of the exam measures the skills of Specifications Writers and emphasizes the importance of developing documentation that goes beyond drawings. Candidates must understand how to identify and prioritize elements needed to prepare, maintain, and refine both the project manual and project specifications. It also assesses the ability to align and coordinate these specifications with the construction documents to ensure consistency and accuracy.
- Topic 3: Codes & Regulations: This section of the exam measures skills of Building Code Specialists and examines how codes and regulations apply at a detailed level during documentation. Candidates are expected to demonstrate knowledge of compliance with the International Building Code (IBC) as well as other specialty regulations, as well as how to interpret and apply these standards to ensure design and documentation meet legal and safety requirements.
- Topic 4: Construction Cost: This section of the exam measures the skills of Construction Managers and focuses on the financial side of project execution. It evaluates the ability to analyze construction cost estimates to confirm that they align with project design intent and budgetary constraints. Although this is the smallest section, it is critical for ensuring projects remain feasible and economically viable.

Which of the following documents would the architect need in order to prepare the specifications?
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.

An architect is rehabilitating a historic federal landmark that requires repairs to a garden wall. The existing brick appears to be in good condition; the mortar shows significant signs of deterioration.
Which strategy should the architect propose to repair the damaged wall?
(PDD) Study Guide Reference
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--2 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.
PDD Reference: Historic fabric protection under ''Codes/Regulations & Standards---Historic preservation,'' detailing of masonry repairs in construction documents (Division 04), and QA/QC specifications for repointing.

What is the primary function of the 2 x 4 blocking shown at X in the drawing?
Comprehensive Detailed Explanation with all NCARB ARE 5.0 Project Development and Documentation (PDD) Study Guide Reference:
In wood frame construction, blocking installed between joists at regular intervals (commonly 48 inches on center) serves primarily to brace and stabilize the joists laterally, preventing twisting and lateral displacement under load.
The 2x4 blocking at point X, placed perpendicular between the ceiling joists, acts as cross bracing.
It resists lateral torsional buckling of the joists and distributes loads evenly.
It also helps maintain alignment during construction and after the finish materials are installed.
The blocking does not support the partition top plate directly (that is the function of the studs beneath), nor does it transfer lateral load to the 1x8. Its main role is structural bracing for the joists.

Building construction texts such as ''Fundamentals of Building Construction'' by Allen and Iano, which describe blocking used to brace joists.

For which of the following connections could diagonal bracing be eliminated?
The diagrams depict metal stud or curtain wall connections to structural frames under wind loading. Diagonal bracing can be eliminated when the connection itself provides lateral restraint in both directions.
A: Shows a connection with angles or plates attached to resist both in-plane and out-of-plane forces, creating a moment-resisting connection that can handle wind loads without diagonal bracing.
B, C, D: These connections allow slip or have limited fixity---requiring separate bracing to resist lateral loads.
PDD Reference: ARE 5.0 PDD ''Structural Systems---Lateral load resistance in curtain wall and stud framing connections''; AISC Steel Design Guide for cladding attachment; Curtain wall engineering details.
Which of the following admixtures is used to greatly increase the slump of concrete?
Comprehensive Detailed Explanation with all NCARB ARE 5.0 Project Development and Documentation (PDD) Study Guide Reference:
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.
