CSI CDT cheat sheet

Drawing sheet size standards: ARCH D is 24 x 36 in; ARCH C is 18 x 24 in; ISO A1 is 594 x 841 mm. Sheet size drives scale selection and detail legibility.

Standard architectural scales: 1/8"=1'-0" for floor plans, 1/4"=1'-0" for enlarged plans and sections, 1/2" or 3/4"=1'-0" for details, 1"=1'-0" or larger for section details.

Metric equivalents: 1:100 approximates 1/8"=1'-0"; 1:50 approximates 1/4"=1'-0"; 1:10 and 1:5 are used for details.

CSI Uniform Drawing System divides drawings into discipline designators (A, S, M, E, P, C, L, F, T) followed by a two-digit series (general, plans, elevations, sections, schedules, details).

Drawing set ordering: cover and drawing index, general information and codes, life safety, symbols and abbreviations, site, plans, elevations, sections, enlarged views, schedules, details.

Revision control: each revision gets a delta symbol with a number or letter, a revision date, a description, and a signature block; superseded sheets are stamped or voided, never deleted from the archive.

Issuance types: schematic design (SD), design development (DD), 50% and 90% construction documents, permit set, bid set, and construction issue (100% CD). Each has a defined deliverable and approval milestone.

Document control: transmittals record what was sent, to whom, when, and by what method; RFI and submittal logs are the auditable record of project correspondence.

As-built documentation is prepared by the contractor from marked-up construction documents; record drawings are the design professional's transfer of those marks onto a reproducible base.

MasterFormat 50 divisions: Division 00 Procurement and Contracting Requirements, Division 01 General Requirements, Divisions 02-19 facility construction, 20-29 facility services, 30-39 site and infrastructure, 40-49 process equipment.

SectionFormat organizes each specification section into three parts: Part 1 General (references, submittals, quality assurance), Part 2 Products (materials, components, fabrication), Part 3 Execution (installation, field quality control, cleaning).

Three-part section numbering: Part 1 uses ARTICLE 1.1, 1.2; Part 2 uses 2.1, 2.2; Part 3 uses 3.1, 3.2. Paragraphs within articles are lettered .A, .B and numbered .1, .2.

Division 01 governs all other divisions: submittal procedures, substitution procedures, quality requirements, temporary facilities, closeout, and warranty terms override conflicting text elsewhere.

Closed vs open proprietary specifying: closed lists one named product with no substitutions; open permits named products or equal. 'No substitution' language must be supported by a documented basis of design.

Prescriptive vs performance specifying: prescriptive states means and methods; performance states required results and leaves method to the contractor. Mixed sections must state which governs in a conflict.

Reference standards are cited by full designation and year (e.g., ASTM C150/C150M-22); undated references incorporate the latest edition and shift risk to the contractor.

Substitution requests are typically due within a stated period after award (commonly 10 days to 30 days) and require a comparison of the proposed product to the specified product, including performance data and cost impact.

Language rules: use imperative mood, present tense, and 'shall' for requirements; avoid 'should', 'may', 'as required', and 'or equal' unless the substitution procedure is explicitly invoked.

Evaluation hierarchy: code listing and labeling (UL, FM, ICC-ES ESR) first, then ASTM or ISO test compliance, then manufacturer published data, then third-party certification such as GREENGUARD or Cradle to Cradle.

ICC-ES Evaluation Service Reports (ESR) document code compliance for products not covered by the code text; an ESR number is a verifiable citation in a specification.

Fire-resistance ratings come from tested assemblies listed in UL Fire Resistance Directory designs (e.g., G, U, V, L series); the assembly design number, not the product alone, establishes the rating.

Surface burning characteristics: ASTM E84 reports flame spread and smoke developed index; Class A is flame spread 0-25, Class B 26-75, Class C 76-200.

Slip resistance: ANSI A326.3 / DCOF AcuTest measures dynamic coefficient of friction on wet tile; 0.42 or greater is the common minimum for level interior wet areas.

Life-cycle cost compares initial cost plus maintenance, energy, replacement, and disposal over a stated study period, discounted to present value; lowest first cost is not the lowest life-cycle cost.

Source documents to request: product data sheets, safety data sheets (SDS, 16-section GHS format), installation instructions, warranty sample, test reports, and environmental product declarations (EPD).

Sourcing checks: verify the manufacturer is current, the specified model is not discontinued, lead time meets the schedule, and local availability of replacement parts and service exists.

Basis-of-design substitution comparison should address form, fit, function, fire rating, acoustics, finish, warranty, and maintenance - not price alone.

RFI content: a single clear question, drawing or specification reference, proposed solution, schedule impact, and a required response date; the answer becomes a clarification, not a change, unless it alters cost or time.

Change order vs construction change directive: a change order is signed by owner and contractor and adjusts contract sum or time; a CCD directs work before agreement on price and is later converted to a change order.

Submittal review stamps: 'No Exceptions Taken', 'Make Corrections Noted', 'Revise and Resubmit', 'Rejected', and 'Submit Specified Item'. A review does not relieve the contractor of contract compliance.

Meeting minutes record date, attendees, agenda items, decisions, action items with responsible party and due date, and open items carried forward; minutes are distributed promptly and become part of the record.

Shop drawings are contractor-prepared detail drawings showing fabrication and installation; they are not design documents and do not supersede the contract documents.

Field report content: date, weather, personnel and equipment on site, work in progress by location, observations, deficiencies, tests performed, and photographs with references.

Document distribution matrix defines who receives what at each issuance; the same matrix governs RFIs, submittals, change orders, and closeout documents.

Escalation path for unresolved issues: contractor to design professional to owner's representative, with time limits stated in the general conditions.

Closeout package: as-built record documents, operation and maintenance manuals, warranties, attic stock, final testing reports, and a punch list closed out before final payment.

MasterFormat 50 divisions: Division 00 Procurement and Contracting Requirements, Division 01 General Requirements, Divisions 02-19 facility construction, 20-29 facility services, 30-39 site and infrastructure, 40-49 process equipment.

SectionFormat organizes each specification section into three parts: Part 1 General (references, submittals, quality assurance), Part 2 Products (materials, components, fabrication), Part 3 Execution (installation, field quality control, cleaning).

Three-part section numbering: Part 1 uses ARTICLE 1.1, 1.2; Part 2 uses 2.1, 2.2; Part 3 uses 3.1, 3.2. Paragraphs within articles are lettered .A, .B and numbered .1, .2.

Division 01 governs all other divisions: submittal procedures, substitution procedures, quality requirements, temporary facilities, closeout, and warranty terms override conflicting text elsewhere.

Closed vs open proprietary specifying: closed lists one named product with no substitutions; open permits named products or equal. 'No substitution' language must be supported by a documented basis of design.

Prescriptive vs performance specifying: prescriptive states means and methods; performance states required results and leaves method to the contractor. Mixed sections must state which governs in a conflict.

Reference standards are cited by full designation and year (e.g., ASTM C150/C150M-22); undated references incorporate the latest edition and shift risk to the contractor.

Substitution requests are typically due within a stated period after award (commonly 10 days to 30 days) and require a comparison of the proposed product to the specified product, including performance data and cost impact.

Language rules: use imperative mood, present tense, and 'shall' for requirements; avoid 'should', 'may', 'as required', and 'or equal' unless the substitution procedure is explicitly invoked.

Evaluation hierarchy: code listing and labeling (UL, FM, ICC-ES ESR) first, then ASTM or ISO test compliance, then manufacturer published data, then third-party certification such as GREENGUARD or Cradle to Cradle.

ICC-ES Evaluation Service Reports (ESR) document code compliance for products not covered by the code text; an ESR number is a verifiable citation in a specification.

Fire-resistance ratings come from tested assemblies listed in UL Fire Resistance Directory designs (e.g., G, U, V, L series); the assembly design number, not the product alone, establishes the rating.

Surface burning characteristics: ASTM E84 reports flame spread and smoke developed index; Class A is flame spread 0-25, Class B 26-75, Class C 76-200.

Slip resistance: ANSI A326.3 / DCOF AcuTest measures dynamic coefficient of friction on wet tile; 0.42 or greater is the common minimum for level interior wet areas.

Life-cycle cost compares initial cost plus maintenance, energy, replacement, and disposal over a stated study period, discounted to present value; lowest first cost is not the lowest life-cycle cost.

Source documents to request: product data sheets, safety data sheets (SDS, 16-section GHS format), installation instructions, warranty sample, test reports, and environmental product declarations (EPD).

Sourcing checks: verify the manufacturer is current, the specified model is not discontinued, lead time meets the schedule, and local availability of replacement parts and service exists.

Basis-of-design substitution comparison should address form, fit, function, fire rating, acoustics, finish, warranty, and maintenance - not price alone.

RFI content: a single clear question, drawing or specification reference, proposed solution, schedule impact, and a required response date; the answer becomes a clarification, not a change, unless it alters cost or time.

Change order vs construction change directive: a change order is signed by owner and contractor and adjusts contract sum or time; a CCD directs work before agreement on price and is later converted to a change order.

Submittal review stamps: 'No Exceptions Taken', 'Make Corrections Noted', 'Revise and Resubmit', 'Rejected', and 'Submit Specified Item'. A review does not relieve the contractor of contract compliance.

Meeting minutes record date, attendees, agenda items, decisions, action items with responsible party and due date, and open items carried forward; minutes are distributed promptly and become part of the record.

Shop drawings are contractor-prepared detail drawings showing fabrication and installation; they are not design documents and do not supersede the contract documents.

Field report content: date, weather, personnel and equipment on site, work in progress by location, observations, deficiencies, tests performed, and photographs with references.

Document distribution matrix defines who receives what at each issuance; the same matrix governs RFIs, submittals, change orders, and closeout documents.

Escalation path for unresolved issues: contractor to design professional to owner's representative, with time limits stated in the general conditions.

Closeout package: as-built record documents, operation and maintenance manuals, warranties, attic stock, final testing reports, and a punch list closed out before final payment.

Drawing sheet size standards: ARCH D is 24 x 36 in; ARCH C is 18 x 24 in; ISO A1 is 594 x 841 mm. Sheet size drives scale selection and detail legibility.

Standard architectural scales: 1/8"=1'-0" for floor plans, 1/4"=1'-0" for enlarged plans and sections, 1/2" or 3/4"=1'-0" for details, 1"=1'-0" or larger for section details.

Metric equivalents: 1:100 approximates 1/8"=1'-0"; 1:50 approximates 1/4"=1'-0"; 1:10 and 1:5 are used for details.

CSI Uniform Drawing System divides drawings into discipline designators (A, S, M, E, P, C, L, F, T) followed by a two-digit series (general, plans, elevations, sections, schedules, details).

Drawing set ordering: cover and drawing index, general information and codes, life safety, symbols and abbreviations, site, plans, elevations, sections, enlarged views, schedules, details.

Revision control: each revision gets a delta symbol with a number or letter, a revision date, a description, and a signature block; superseded sheets are stamped or voided, never deleted from the archive.

Issuance types: schematic design (SD), design development (DD), 50% and 90% construction documents, permit set, bid set, and construction issue (100% CD). Each has a defined deliverable and approval milestone.

Document control: transmittals record what was sent, to whom, when, and by what method; RFI and submittal logs are the auditable record of project correspondence.

As-built documentation is prepared by the contractor from marked-up construction documents; record drawings are the design professional's transfer of those marks onto a reproducible base.
