Document Coordination and Code Compliance (Final Project)

Document Coordination and Code Compliance on the ExAC: the 1 sub-category you need to know

Examitect's ExAC study plan places Document Coordination and Code Compliance in Section 3 as a Final Project topic. It contains one sub-category, 8.6, which appears in scenario-based, multi-select, ordering, and definition question formats throughout the exam. The sub-category draws from a large set of references that overlap with neighbouring Section 3 topics, particularly Construction Documents and Specifications and MasterFormat, so time you spend here pays dividends across multiple topic pages.

What document coordination is, and what it produces

Document coordination is the quality control process that confirms a construction document package is consistent internally, consistent with consultant documents, and compliant with the applicable building code, before it is issued for building permit and tender. It is not a single pass at the end of production: it runs continuously through the construction documents phase, with formal reviews at 50%, 90%, and 100% completion.

The output is a permit-ready, tender-ready set of documents that contains no internal contradictions, no gaps between disciplines, and no design elements that violate the code. Contractors can read it, price it, and build from it without ambiguity.

Three dimensions of coordination

1. Internal coordination: Every keynote on the drawings links to a specification section. Dimensions in plan match dimensions in detail. The door schedule matches the doors drawn in plan. The finish schedule matches the finishes called out in room tags.
2. Consultant coordination: Architectural drawings align with structural, mechanical, electrical, and civil drawings. Beam depths, duct routes, pipe chases, and slab-on-grade elevations are reconciled across disciplines.
3. Code compliance: The design conforms to the occupancy classification, construction type, height and area limits, fire-resistance requirements, egress provisions, and accessibility standards set by the applicable code.

8.6 Evaluate and coordinate construction documents for code compliance

What sub-category 8.6 tests. Sub-category 8.6 of Examitect's ExAC study plan, taken from the CACB blueprint, is "Evaluate and coordinate construction documents for code compliance." The primary references are CHING chapters 2.08 to 2.13 and appendices A.03, A.10, and A.12, plus CHOP chapters 2.4, 5.3, 5.4, 6.4, and 6.8. The supplementary reference is The Architect's Studio Companion sections 1, 5, and 7.

The code compliance sheet

Most architectural offices document code compliance on a dedicated sheet (or set of sheets) in the architectural drawing package. This code sheet summarizes every code determination in one place so the permit authority can verify the analysis without hunting through the full drawing set. A typical code sheet includes the following items:

1. Project address, legal description, and applicable code edition
2. Major occupancy classification for each portion of the building
3. Construction type (combustible or noncombustible; or IBC Type I through V if using a US reference)
4. Building height (storeys above grade and height in metres) and total gross floor area
5. Allowable height and area from the code tables, with any applicable increases for sprinklers
6. Fire-resistance schedule: ratings required for structural frame, bearing walls, floor/ceiling assemblies, and roof assemblies
7. Occupant load calculation and required number and width of exits
8. Travel distance limits and actual maximum travel distances
9. Accessibility provisions: accessible route, parking, entrance, washrooms
10. Authority having jurisdiction notes: any variances, equivalences, or alternative solutions

Coordination review milestones

A well-run office schedules formal coordination reviews at defined milestones rather than reviewing once at the end. Common milestones from CHOP 5.4 and 6.4 include:

• 50% CD: Structural grid, slab levels, major mechanical rooms, and primary egress paths are locked. Coordination overlay between architectural and consultant drawings is performed for the first time.
• 90% CD: All drawings and specifications are drafted. Second full coordination check. Code compliance sheet is complete. Checklists for architectural, structural, mechanical, and electrical are completed and signed off.
• 100% CD (permit issue): All review comments from the 90% check are incorporated. Final code compliance check. Documents are sealed and issued for permit and tender.

Code compliance: occupancy classification and construction type

Before you can complete the code sheet, you need two determinations: the occupancy classification and the construction type. These two inputs drive almost every other code requirement.

Major occupancy groups under the NBC 2020

The NBC classifies buildings by their intended use. The six major occupancy groups are:

• Group A (Assembly): theatres, arenas, churches, lecture halls, libraries, museums, restaurants. Divided into A-1 (performing arts), A-2 (indoor assembly), A-3 (arenas and pools), A-4 (open-air assembly).
• Group B (Care, Treatment, or Detention): hospitals, nursing homes, correctional facilities. Divided into B-1 (detention), B-2 (medical treatment), B-3 (care without medical treatment).
• Group C (Residential): dwelling units, apartment buildings, hotels, dormitories.
• Group D (Business and Personal Services): offices, medical offices, hairdressing shops.
• Group E (Mercantile): retail stores, supermarkets, markets.
• Group F (Industrial): manufacturing, processing, warehousing. Divided into F-1 (high hazard), F-2 (medium hazard), F-3 (low hazard including enclosed parking).

Construction types under the IBC (CHING reference)

CHING chapters 2.10 and 2.11 describe the five IBC construction types used in the US reference, which the ExAC also tests through CHING. The types progress from most fire-resistive to least:

• Type I: major building elements of noncombustible materials (concrete, masonry, protected steel). Highest fire-resistance ratings.
• Type II: similar to Type I but with reduced fire-resistance ratings for the major elements.
• Type III: noncombustible exterior walls; interior elements of any code-permitted material.
• Type IV: includes mass timber subcategories (IV-A, IV-B, IV-C, IV-HT). Exterior walls noncombustible; major interior elements of solid or laminated wood of specified minimum dimensions.
• Type V: structural elements and walls of any code-permitted material. Least fire-resistive.

Under the NBC, the equivalent distinction is between combustible and noncombustible construction, with specific requirements in Division B Part 3 tables.

Fire-resistance ratings by element type

IBC Table 601 (reproduced in CHING 2.11) lists required fire-resistance ratings in hours for each construction type. For example, Type I-A requires a 3-hour rating on the primary structural frame and exterior bearing walls, while Type V-B requires no rating on any element. You read across the table with your chosen construction type and confirm the ratings shown on the drawings and specifications match the table requirements.

Heights, areas, fire separations, and sprinklers

Once you have the occupancy and construction type, you use the height and area tables to confirm the building fits within the code's allowable limits.

Reading the height and area tables

CHING 2.13 and The Architect's Studio Companion Section 7 both present height and area tables. The tables correlate occupancy group and construction type to three limits: maximum building height in storeys, maximum building height in metres (or feet), and maximum area per floor in square metres (or square feet) for a single-storey building and for multistorey buildings. You pick the occupancy row and the construction type column and read off the limits.

Two adjustments can increase the allowable area:

• Sprinkler increase: An automatic fire sprinkler system throughout the building permits the allowable area per floor to be multiplied by a factor (typically 2 or 3, depending on the code edition and occupancy). Always confirm the sprinkler system is shown in the mechanical drawings and specified in the specifications.
• Open perimeter increase: Where two or more sides of the building face a street or open yard, additional area is permitted. The percentage varies with the fraction of the building perimeter exposed.

Fire walls, fire separations, and occupancy separations

When a building exceeds the base allowable area, one option is to divide it with a fire wall into smaller fire areas. Under both the IBC (CHING 2.13) and the NBC, fire walls must:

• Have a fire-resistance rating sufficient to prevent spread of fire between compartments.
• Run continuously from foundation to parapet or to the underside of a noncombustible roof.
• Restrict all openings to a maximum percentage of the wall length, with self-closing fire doors, fire-rated glazing, and fire dampers in ducts.

When a building contains more than one occupancy, the NBC requires occupancy separations between groups where the code specifies. The Studio Companion Section 7 provides a table of which occupancy combinations require separation and what rating applies.

Fire separation distance

The distance from a building's exterior wall to the property line (or an assumed line between buildings on the same site) drives the fire-resistance rating required for that wall and the permitted percentage of openings in it. A wall with a large fire separation distance may have fewer or no fire-resistance requirements; a wall close to a property line needs a high rating and few or no openings.

Fire-rated construction and assemblies

CHING Appendix A.12 introduces fire-rated construction: materials and assemblies that have been tested to a standard time-temperature curve and assigned a rating in hours representing how long they withstand fire exposure without collapsing, passing flame, or exceeding a temperature limit on the protected side.

How fire ratings are determined

A full-size specimen is subjected to a standard fire test. The rating period ends when the assembly collapses, when a measurable flame or hot gas passes through, or when the temperature on the unexposed face exceeds 139 degrees Celsius above ambient. Common ratings are 30 minutes, 1 hour, 2 hours, and 4 hours. The rating appears in the IBC tables 721.1(1), (2), and (3), which list prescriptive assemblies by material and thickness.

Fire-protecting materials

Materials used to provide fire protection must be non-combustible and able to withstand very high temperatures without disintegrating. They must also be low heat conductors. Common fire-protective materials include:

• Gypsum wallboard, particularly Type X (which contains glass fibres to prevent the board from falling apart at high temperatures)
• Concrete, often with lightweight aggregate
• Gypsum or vermiculite plaster on metal or gypsum lath
• Spray-applied mineral fibre fireproofing on structural steel

Common assembly examples

CHING A.12 illustrates representative assemblies for floors and roofs, and for walls and partitions. Typical 1-hour wall: 2x4 wood studs at 400 mm on-centre, 16 mm Type X gypsum board on each side. Typical 2-hour wall: 2x4 studs at 400 mm, two layers of 16 mm Type X gypsum board on each side, or steel studs with 16 mm Type X gypsum board. For concrete masonry walls, an 8-inch (205 mm) wall achieves a 2- to 4-hour rating depending on aggregate type.

Documenting fire-rated assemblies on drawings

The fire-resistance schedule on the code sheet lists every rated assembly in the project by UL or ULC assembly number (or by prescriptive NBC description), the required rating, and where in the building it applies. The architectural drawings show these assemblies in wall sections, details, and partition type legends. The specifications (CSI MasterFormat Division 07 80 00, Fire and Smoke Protection) describe the installation requirements. You verify all three are consistent during the coordination review.

Means of egress on the drawings

Egress provisions are among the most scrutinized items in a building permit review. CHING Appendix A.10 and The Architect's Studio Companion Section 5 both cover the egress system in detail. You confirm egress compliance as part of the code sheet and show the calculations on the drawings.

Three components of the egress system

1. Exit access: The path from any occupied point in the building to an exit. Includes aisles, corridors, ramps, and unenclosed stairways. Must be unobstructed and directly accessible.
2. Exit: The protected portion of the egress system: an enclosed stairway, horizontal exit, or exterior door leading to the outside. Must be fire-resistance rated and separated from the rest of the building.
3. Exit discharge: The path from the exit to a public way or safe open area outside the building.

Occupant load and required exits

Occupant load is the number of persons the code assumes can occupy a space at one time. You calculate it by dividing the floor area assigned to a use by the occupant load factor for that use from the code's occupant load table (NBC Division B Table 3.1.17.1 or IBC Table 1004.5). Once you have the occupant load, the code tells you the minimum number of exits required and their minimum aggregate width. Most occupancies require at least two exits once occupant load exceeds a code-defined threshold.

Travel distance

Travel distance is the distance an occupant must walk from the most remote point in a space to the nearest exit. The NBC and IBC both specify maximum travel distances that vary by occupancy and by the presence of sprinklers. You measure travel distance along the actual path of travel, accounting for furnishings and room geometry. You show the maximum actual travel distance on the code sheet and confirm it does not exceed the code limit.

How egress appears on drawings

Egress is documented on the drawings and code sheet through an occupant load table (listing each space, its area, occupant load factor, and calculated load), exit location plans showing the exits and exit discharge paths, travel distance arrows from the most remote points to exits, and corridor and stair sizing calculations confirming the required exit widths are provided. Any dead-end corridor is flagged and confirmed to be within the allowable length.

Accessibility provisions

CHING Appendix A.03 summarizes accessibility guidelines. In Canada, the primary accessibility requirements come from NBC Division B Section 3.8 (Barrier-Free Design). The code sheet must confirm that accessible routes, accessible parking, accessible entrances, and accessible facilities are provided.

Accessible routes

An accessible route is a continuous, barrier-free path connecting all accessible features and spaces. Walking surfaces on an accessible route must be firm and stable, with a maximum running slope of 1:20 and a maximum cross slope of 1:50. Changes in level:

• Up to 6 mm: may be vertical.
• 6 mm to 13 mm: must be bevelled at a slope of 1:2 or less.
• Greater than 13 mm: must be ramped.

Minimum clear width is 920 mm for a single wheelchair user. Where two wheelchairs must pass, the minimum is 1,500 mm.

Key dimensions to know for the exam

• Turning space for a wheelchair: 1,500 mm clear circle, or a T-shaped space with arms at least 900 mm wide and 1,500 mm long.
• Clear floor space for forward or parallel approach: 760 mm by 1,220 mm minimum.
• Maximum reach height (forward reach): 1,220 mm; minimum: 380 mm. Maximum side reach: 1,370 mm.
• Accessible door clear opening width: 850 mm minimum (NBC) or 815 mm minimum (ADA).
• Ramp maximum slope: 1:12.

Accessibility on the drawings and code sheet

The code sheet lists the accessible features: number of accessible parking stalls (typically 1 in 25 for most occupancies), accessible entrance location, accessible route from parking to entrance and throughout the building, accessible washroom count and location, and any equivalences or alternative solutions requested under NBC 3.8 or local bylaw. The drawings show accessible routes, accessible parking stalls with the international symbol, accessible washroom layouts, and ramp profiles with slope callouts.

Quality management and coordination checklists

CHOP Chapter 5.4 defines quality management in architectural practice and is the primary reference for how offices structure their document review processes. Understanding the distinction between quality planning, quality assurance, and quality control is a direct ExAC target.

Quality control vs. quality assurance

• Quality control: the ongoing, systematic review of drawings and specifications as they are produced. Checking each drawing for errors, omissions, and conflicts as the work progresses. This is what happens at 50%, 90%, and 100% CD milestones.
• Quality assurance: planned and systematic activities based on sampling rather than continuous review. For example: auditing a sample of completed projects to identify recurring coordination errors, then refining the office checklist to prevent them on future projects.

CHOP 5.4 notes that "quality is planned in, not simply inspected in." The cost of avoiding a mistake is usually less than the cost of correcting it. An unresolved coordination issue deferred to the tender phase may require an addendum, redesign, re-tendering, and potentially a change order: far more expensive than two hours of coordination work during production.

Coordination checklists

CHOP 6.4 Appendix lists the checklist types that support a quality-managed construction documents phase:

• Checklist for internal review of drawings: architectural
• Checklist for internal review of drawings: structural
• Checklist for internal review of drawings: mechanical
• Checklist for internal review of drawings: electrical
• Checklist for life safety information to include on drawings: architectural
• Checklist for life safety information to include on drawings: structural, mechanical, and electrical
• NBC data matrix (a structured summary of code determinations)

The checklists have three parts: items to check before production proceeds in detail, items to check during execution, and items to verify before the drawing is considered complete. This structure follows the quality management approach described in CHOP 5.4.

Work plan as a coordination tool

CHOP 5.4 recommends a master work plan adapted for each project. The work plan lists every task required to complete the construction documents, assigns responsibility, and sets deadlines. When combined with the checklists, it gives project managers visibility into what has been reviewed and what still needs attention before each milestone.

Consultant coordination, communications, and project forms

CHOP 5.3 (Communications Management) and 6.8 (Sample Forms) cover the communication structures and documentation tools that architects use to keep the consultant team aligned through the construction documents phase and into tender.

Architect's coordination role

The architect coordinates the interfaces between disciplines. CHOP 5.3 is clear: the architect does not produce or check the consultant's work for technical accuracy. Each consultant is responsible for their own drawings, bears professional responsibility for their discipline, and seals their own drawings under their licence. The architect's role is to identify where the disciplines intersect (steel beams meeting duct routes, slab penetrations for plumbing, panel locations in millwork) and ensure those intersections are resolved before the documents are issued.

Construction documents as a communication tool

CHOP 5.3 states that when preparing construction documents, you must always remember they are a communication tool and view them from the contractor's perspective. Well-coordinated documents result in:

• More accurate bids with a smaller spread between high and low bidders
• Fewer addenda during the tender period
• Better understanding of design intent by the builder and trades
• Fewer RFIs and delays during construction
• Lower final cost to the client

Addenda

An addendum is a formal document issued during the tender period that corrects, clarifies, or adds information to the bid documents. Under CHOP 6.8:

• Each addendum is numbered and dated.
• It must be distributed to all bidders at the same time and through the same channel.
• It must be issued generally no later than four days before bid closing (the tender documents should specify the exact cutoff).
• Addenda become part of the construction contract; the successful bidder is bound by their content.

Revision control on drawings

After the construction documents are issued, any change is shown on the drawing by a revision cloud around the changed area, a filled triangle (delta) keyed to the revision number in the title block revision column, and the date of the revision. The issue register tracks every version of every drawing, confirming which revision number is current and when it was issued. During tender, revised drawings are packaged as addenda and sent to all bidders.

Project forms used during coordination and tender

CHOP 6.8 describes the standard project forms. Key forms for document coordination and tender include:

• Transmittal letter: documents what was sent, to whom, when, how, and for what action (for review, for approval, for information).
• Addendum: lists changes to the bid documents; includes project name, number, addendum number, date, and itemized list of changes.
• Summary of bids: records each bidder's name and their bid amount after tender closes.
• Letters of Assurance (in BC, Alberta, and Nova Scotia): signed and sealed by the registered professional at building permit application and at the occupancy permit stage, certifying field review responsibilities.

How each reference fits sub-category 8.6

Each reference cited in Examitect's ExAC study plan for sub-category 8.6 covers a specific slice of the topic. Understanding which reference covers which concept lets you look up answers efficiently during the exam.

Key document coordination and code compliance terms (glossary)

Addendum

A formal written change to the bid documents issued during the tender period. Distributed to all bidders simultaneously, generally at least four days before bid closing. Becomes part of the construction contract.

Alternative solution

A design approach that achieves the objective of a code provision by means other than the prescriptive requirement. Must be shown to meet the intent of the code; approved by the authority having jurisdiction.

Authority having jurisdiction (AHJ)

The government body or official responsible for enforcing the building code and issuing permits. CHOP 2.4. Building officials may issue compliance orders, stop-work orders, and lay charges.

Code compliance sheet

A dedicated drawing or drawing set in the architectural package that summarizes occupancy, construction type, height, area, fire resistance schedule, exit calculations, and accessibility provisions for the permit authority.

Construction type

A code-defined classification of buildings based on the fire resistance of their major structural elements. IBC defines five types (I through V). NBC distinguishes combustible and noncombustible construction. Drives fire-resistance ratings and allowable height and area.

Document coordination

The structured review of construction documents for internal consistency (drawings vs. specs), external consistency (architectural vs. consultant), and code compliance, conducted at defined milestones before issuing for permit and tender.

Exit

The protected portion of the egress system, typically an enclosed stairway or exterior door. Must be fire-resistance rated and separated from the rest of the building by rated construction.

Exit access

The portion of the egress system from any point in the building to the nearest exit. Includes corridors, aisles, and unenclosed ramps. Travel distance and dead-end corridor limits apply here.

Fire separation distance

The distance between a building's exterior wall and the property line or an assumed line between buildings on the same site. Drives the fire-resistance rating required for the exterior wall and the maximum percentage of openings permitted.

Fire wall

A wall with a fire-resistance rating sufficient to prevent fire spread from one portion of a building to another. Must run continuously from foundation to parapet or noncombustible roof. All openings must be protected.

Letter of Assurance

A form required in some provinces (BC, Alberta, Nova Scotia) signed and sealed by the registered professional at building permit application and occupancy permit stages. Certifies the professional's commitment to field review for general code compliance.

Major occupancy

The NBC classification of a building or portion by its primary use (A, B, C, D, E, or F). Determines which height and area tables apply and which separations are required between uses.

Occupant load

The number of persons the code assumes can occupy a space at one time. Calculated by dividing the floor area by the occupant load factor for the use. Drives exit count, exit width, and travel distance requirements.

Quality assurance

Planned and systematic activities based on sampling, intended to confirm that quality management processes are working. Distinct from quality control (CHOP 5.4).

Quality control

The ongoing, systematic review of drawings and specifications during production to catch errors, omissions, ambiguities, and conflicts before the documents are issued. CHOP 5.4.

Revision cloud

A graphic notation on a drawing (a cloud-shaped outline around the changed area, plus a delta triangle keyed to a revision number) that identifies what changed and when. Used to track changes after the first issue of documents.

Travel distance

The distance a building occupant must walk from the most remote point in a space to the nearest exit. Code-limited by occupancy and sprinkler provision. Measured along the actual path of travel.

Type X gypsum board

A gypsum board product containing glass fibres to improve fire resistance. Standard in 1-hour and 2-hour fire-rated wall assemblies. The "X" designation is defined by ASTM C1396.

How document coordination and code compliance questions are asked on the ExAC

Common ExAC traps in document coordination questions

1. Architect correcting consultant work. The architect coordinates interfaces; each consultant is responsible for their own technical accuracy. An answer that has the architect correcting a structural engineer's calculations is wrong.
2. Issuing a revision instead of an addendum. Changes to bid documents during tender go out as addenda, not revisions. Revisions are for changes after the contract is awarded.
3. Skipping the code sheet. Questions sometimes present a scenario where the design appears code-compliant but the code sheet has not been completed. The right answer is to complete the code sheet before issuing for permit, not to issue and correct later.
4. Confusing quality control and quality assurance. Quality control is continuous review during production. Quality assurance is systematic sampling after the fact. CHOP 5.4 distinguishes them clearly.
5. Ignoring the addendum cutoff. An addendum issued the day before tender closing violates the four-day minimum in CHOP 6.8. The correct action is to extend the tender closing date or confirm with the client.
6. Treating an alternative solution as automatic. An alternative solution is not a right: it requires AHJ approval. Assuming the AHJ will accept an equivalence without submission and approval is wrong.

Tips for Intern Architects studying document coordination and code compliance

• Read the code sheet first, not the drawings. On the exam and in practice, the code sheet is your anchor. If the code sheet is wrong, every drawing that follows it may be wrong too.
• Know your occupancy groups cold. The NBC groups A through F come up constantly. You should be able to classify any common building type (school, apartment, office, warehouse, hospital) without looking at a table.
• Practise the height and area tables. Use The Architect's Studio Companion Section 7 to walk through several building scenarios: choose an occupancy, choose a construction type, find the allowable area, apply a sprinkler increase. Doing this three or four times builds the skill faster than re-reading the tables.
• Pair this topic with construction documents. They share CHING chapters 2.08 to 2.13, CHOP 6.4, and CHOP 6.8. Study them back to back to save time and reinforce shared concepts.
• Use the CHOP appendix checklists as a study guide. The CHOP 6.4 Appendix lists exactly what a quality-managed CD package must contain. These items appear directly in exam questions.
• Trace every number back to a clause. When you see a dimension or threshold on the code sheet (occupant load factor, travel distance limit, required exit width), know which NBC or IBC table it comes from. Examiners write scenario questions that test whether you know the source, not just the number.

How to study document coordination and code compliance in 10 to 15 hours

1. Hours 1 to 4: Read CHING chapters 2.08 to 2.13 and appendices A.03, A.10, and A.12. Sketch the occupancy table (A through F), the IBC construction type matrix with fire-resistance ratings, the egress system diagram, and the standard accessible route dimensions. These sketches become your exam cheat sheet.
2. Hours 5 to 8: Read CHOP chapters 2.4, 5.3, 5.4, 6.4, and 6.8. Focus on the definitions, the quality control vs. quality assurance distinction, the coordination milestone structure, and the addendum requirements. Note the appendix checklist titles from CHOP 6.4.
3. Hours 9 to 10: Work through The Architect's Studio Companion sections 1, 5, and 7. Use the height and area tables for two or three building scenarios. Practice sizing an egress system using the Studio Companion's egress tables for the NBC of Canada.
4. Hours 11 to 15: Use Examitect practice questions focused on sub-category 8.6. After each incorrect answer, go back to the specific reference and re-read the relevant page. Track which traps you fall into repeatedly and review those before the exam.
