ARE PA Study Guide - Programming & Analysis

ARE 5.0 Programming & Analysis (PA) - Comprehensive Study Guide

The Programming & Analysis (PA) division covers the pre-design phase of architectural projects. It tests your ability to gather information, analyze site and environmental conditions, understand regulatory constraints, and translate client needs into a viable building program. PA requires broad knowledge across site analysis, codes, zoning, environmental systems, and accessibility - making it one of the more content-diverse divisions.

PA contains approximately 75 questions with a 3 hour 20 minute time limit. The division emphasizes your ability to evaluate existing conditions and constraints before design begins, so many questions present site data, zoning maps, or program requirements that you must interpret.

Site Analysis

Site analysis is the foundation of PA. You must evaluate physical, environmental, and regulatory characteristics of a site:

• Topography: Read contour maps to determine slopes, drainage patterns, and buildable areas. Contour lines close together indicate steep slopes; widely spaced lines indicate flat terrain. Water flows perpendicular to contour lines from high to low elevations.
• Solar Orientation: Understand sun paths for different seasons and latitudes. South-facing facades receive the most solar exposure in the Northern Hemisphere. East and west exposures create glare and overheating challenges. Design responses include building orientation, shading devices, and glazing selection.
• Wind Patterns: Prevailing winds affect natural ventilation, building pressurization, snow drifting, and pedestrian comfort. Windbreaks (landforms, vegetation, structures) can redirect or attenuate wind.
• Vegetation and Ecology: Existing trees and vegetation affect site planning. Many jurisdictions protect trees above a certain caliper. Existing vegetation indicates soil conditions and drainage patterns.
• Utilities and Infrastructure: Locate existing water, sewer, gas, electric, and telecom services. Determine capacities and connection points. Understand the difference between public and private utility systems.
• Access and Circulation: Evaluate vehicular access points, sight distances, traffic patterns, pedestrian routes, and public transit connections.

For a thorough review of site evaluation concepts, see our Site Analysis topic guide.

Programming

Architectural programming translates the client's needs into quantifiable requirements:

• Space Programming: Develop net and gross area requirements. Net area is usable space. Gross area includes walls, circulation, and mechanical space. The net-to-gross ratio (efficiency ratio) varies by building type - typically 60-70% for hospitals, 75-85% for offices, and 85-95% for warehouses.
• Adjacency Requirements: Document which spaces need to be near each other using adjacency matrices or bubble diagrams. Adjacencies can be based on functional relationships, shared resources, or security requirements.
• Stacking and Blocking: Organize programmed spaces vertically (stacking) and horizontally (blocking) to meet adjacency requirements within the building footprint and site constraints.
• Programming Methods: William Pena's "Problem Seeking" method organizes programming around five categories: Function, Form, Economy, Time, and Energy. This framework appears frequently on the exam.

Zoning and Land Use

Zoning regulations control what can be built on a site:

• Use Classifications: Residential, commercial, industrial, agricultural, mixed-use, and special purpose. Know the typical permitted, conditional, and prohibited uses in each zone.
• Dimensional Requirements: Setbacks (front, side, rear), maximum building height, lot coverage (building footprint / lot area), Floor Area Ratio (FAR = total floor area / lot area), and open space requirements.
• FAR Calculations: If a site is 20,000 SF with a FAR of 3.0, the maximum floor area is 60,000 SF. This could be 3 floors at 20,000 SF each, 6 floors at 10,000 SF each, or any combination that totals 60,000 SF or less.
• Variances and Special Permits: A variance provides relief from specific zoning requirements due to hardship. A special permit allows a conditional use that requires additional review. Understand the process and criteria for each.
• Planned Unit Development (PUD): A flexible zoning tool that allows mixed uses and modified dimensional requirements in exchange for a comprehensive site plan.

Environmental Conditions

• Floodplains: FEMA designates flood zones using Flood Insurance Rate Maps (FIRMs). Zone A and Zone V (coastal) are Special Flood Hazard Areas (SFHA) with a 1% annual chance of flooding (100-year flood). Base Flood Elevation (BFE) determines minimum building elevation.
• Wetlands: Protected under the Clean Water Act. The Army Corps of Engineers regulates fill activities in wetlands. Development in or near wetlands requires permits and often requires mitigation (creating or restoring wetlands elsewhere).
• Brownfields: Previously developed sites with potential contamination. Environmental Site Assessments (Phase I and Phase II ESAs) evaluate contamination risk. Phase I is a records review and visual inspection. Phase II involves sampling and testing.
• Seismic Conditions: Sites in seismic zones require special structural considerations. The IBC uses Seismic Design Categories (A through F) based on soil type and mapped spectral accelerations.

Building Codes (IBC)

PA tests your understanding of how codes constrain building design:

• Occupancy Classification: The IBC classifies buildings by use (A=Assembly, B=Business, E=Educational, F=Factory, H=High-Hazard, I=Institutional, M=Mercantile, R=Residential, S=Storage, U=Utility). Mixed occupancy buildings require either separated or non-separated analysis.
• Construction Types: Types I through V, with subtypes A and B. Type I is the most fire-resistant (non-combustible); Type V is the least (wood frame). Construction type limits building height and area based on occupancy.
• Allowable Area Calculations: Base area from IBC Table 504.4 can be increased through frontage increase (If), sprinkler increase (Is), and multi-story considerations. The formula is Aa = At + [At x If] + [At x Is].
• Height and Area Limitations: Determined by the intersection of occupancy classification and construction type in IBC Tables 504.3 and 504.4.

See our Code Compliance topic guide for detailed IBC analysis.

Accessibility (ADA)

ADA and ICC A117.1 accessibility requirements are tested across multiple ARE divisions, but PA focuses on site-level accessibility:

• Accessible Route: A continuous, unobstructed path from public transportation, parking, and public sidewalks to the building entrance. Must be at least 36 inches wide (44 inches in corridors where required) with passing spaces every 200 feet.
• Accessible Parking: One accessible space per 25 total spaces (up to 100 spaces). Van-accessible spaces required at a ratio of 1 per 6 accessible spaces. Accessible spaces must be closest to the accessible entrance.
• Ramps: Maximum slope of 1:12 (8.33%). Maximum rise of 30 inches per run. Landings required at top, bottom, and every 30 inches of rise. Minimum landing length of 60 inches.
• Site Grading for Accessibility: Accessible routes on sites must not exceed 1:20 (5%) running slope unless designed as ramps. Cross slopes must not exceed 1:48 (2%).

Stormwater Management

Understanding stormwater is important for PA site analysis questions:

• Impervious Coverage: Roofs, paving, and other impervious surfaces increase stormwater runoff. Many jurisdictions limit impervious coverage and require stormwater management for new development.
• Rational Method: Q = CiA, where Q = peak runoff rate, C = runoff coefficient, i = rainfall intensity, A = drainage area. Higher C values (closer to 1.0) indicate more impervious surface.
• Best Management Practices (BMPs): Detention basins, retention ponds, bioswales, rain gardens, permeable pavers, green roofs, and underground storage. These reduce peak runoff rates and improve water quality.
• Low Impact Development (LID): Site design strategies that mimic pre-development hydrology. LID emphasizes distributed, small-scale stormwater controls rather than large centralized facilities.

Soils

• Soil Types: Gravel, sand, silt, and clay in order of decreasing particle size. Gravel and sand are granular (cohesionless) soils with good drainage and bearing capacity. Silt and clay are fine-grained (cohesive) soils that retain water and may have lower bearing capacity.
• Bearing Capacity: The maximum pressure a soil can support. Rock has the highest bearing capacity; organic soils and unconsolidated clays have the lowest. The IBC provides presumptive bearing values.
• Frost Line: The depth to which ground freezes. Foundations must extend below the frost line to prevent frost heave. Frost depth varies by climate - from 0 inches in southern states to 60+ inches in northern states.
• Geotechnical Reports: Soil boring logs, water table elevation, bearing capacity recommendations, and foundation type recommendations. You should be able to read and interpret a basic boring log.

Sample Question Format

Scenario: You are given a site plan showing contour lines, a north arrow, setback lines, and utility locations. The zoning allows FAR of 2.5 on a 15,000 SF lot. Which of the following building configurations is permitted under zoning?

This type of question requires you to calculate allowable floor area (15,000 x 2.5 = 37,500 SF) and evaluate each option against setback and coverage requirements.

Study Tips for PA

1. Practice reading site plans and contour maps. Many PA questions present graphic information you must interpret. Familiarize yourself with contour intervals, spot elevations, and drainage arrows.
2. Know your IBC tables. Allowable height and area, occupancy classifications, and construction types form the backbone of code questions. Practice looking up values quickly.
3. Understand FAR and zoning math. Calculate FAR, lot coverage, and setback impacts for different building configurations. These are straightforward but require attention to detail.
4. Study the Rational Method formula. Q = CiA appears on the exam. Know what each variable represents and how changes in site conditions affect runoff.
5. Review accessibility from a site perspective. PA focuses on accessible routes, parking, and site grading - not interior accessibility (that is covered in PPD and PDD).
6. Use multiple study resources. PA covers a wide range of topics. Supplement your primary study material with our PA flashcards and PA mini exams to test your breadth of knowledge.
