Construction Documentation

name construction-documentation description Comprehensive construction documentation skill covering architectural drawing sets, sheet organization and numbering, drawing standards (line weights, text, hatching, dimensions), BIM Level of Development (LOD) requirements, specification writing using CSI MasterFormat, schedule production (door, window, finish, fixture), and construction administration workflows including RFI processing, submittal review, change orders, site observations, punch lists, and warranty period management. Construction Documentation Construction documentation translates design intent into legally binding, buildable instructions. This skill covers every aspect of producing a complete, coordinated, and code-compliant set of construction documents -- from drawing organization and graphic standards through specifications, schedules, and the architect's role during the construction phase.

1. Drawing Set Organization 1.1 Standard Architectural Drawing Sequence A complete architectural drawing set follows a consistent order that allows contractors, consultants, and reviewers to navigate the documents efficiently. The standard sequence is: Cover Sheet -- project name, address, owner, architect, consultants, project number, issue date, building code summary, occupancy classification, construction type, area tabulation, vicinity map. Drawing List -- complete index of every sheet in the set, organized by discipline with sheet number, title, and revision status. General Notes -- project-wide notes, abbreviations, symbols legend, material keynote legend, accessibility standards referenced, applicable codes and editions. Site Plan -- property boundaries, setbacks, easements, building footprint, grading, paving, landscaping, utilities, site lighting, stormwater management, accessibility routes. Floor Plans -- every level including basement, ground, upper floors, mezzanines, and mechanical penthouse. Show walls, doors, windows, stairs, elevators, room names, room numbers, dimensions, column grid, section cut indicators, elevation markers, detail callouts. Reflected Ceiling Plans (RCP) -- ceiling materials, heights, grid layout, light fixtures, diffusers, sprinkler heads, access panels, ceiling soffits, bulkheads. Roof Plan -- roof slopes, drainage, overflow drains, mechanical equipment, roof access, parapet heights, expansion joints, roof penetrations, fall protection anchorage. Exterior Elevations -- all four sides minimum, material indications, floor lines, ceiling lines, grade line, roof ridge/eave lines, window tags, door tags, material keynotes, vertical dimensions. Building Sections -- longitudinal and transverse sections through the entire building. Show structural system, floor-to-floor heights, foundation, roof structure, wall assemblies at cut, vertical circulation, key dimensions. Wall Sections -- detailed vertical cuts through typical wall assemblies from foundation to roof. Show every layer, flashing, waterproofing, insulation, vapor barriers, structural connections, window head/sill/jamb conditions. Enlarged Plans -- stair plans, elevator plans, toilet rooms, kitchens, lobbies, and other complex spaces at 1:50 or 1:20 scale. Interior Elevations -- wall-by-wall interior views of significant rooms: toilets, kitchens, reception areas, conference rooms. Show casework, tile layouts, fixture locations, outlet heights. Stair and Elevator Details -- stair sections, handrail details, guardrail connections, nosing profiles, elevator pit, shaft dimensions, machine room layout, cab interior elevations. Door Schedule and Details -- door types, frame details, hardware sets, threshold details, ADA clearance diagrams. Window Schedule and Details -- window types, mullion details, sill/head/jamb sections, hardware, performance specifications. Finish Schedule -- room-by-room listing of floor, base, wall, and ceiling finishes with finish codes cross-referenced to specifications. Detail Sheets -- miscellaneous construction details not covered elsewhere: expansion joints, control joints, flashing, waterproofing, miscellaneous metal, signage mounting. 1.2 Sheet Numbering Conventions Sheet numbers use a discipline prefix followed by a category digit and sequential number. The standard architectural prefix is "A": Sheet Series Category Examples A0.01 General (cover, notes) A0.01, A0.02, A0.03 A1.01 Floor Plans A1.01, A1.02, A1.03 A1.50 Reflected Ceiling Plans A1.50, A1.51 A1.70 Roof Plans A1.70, A1.71 A2.01 Exterior Elevations A2.01, A2.02 A2.50 Interior Elevations A2.50, A2.51, A2.52 A3.01 Building Sections A3.01, A3.02 A3.50 Wall Sections A3.50, A3.51 A4.01 Enlarged Plans A4.01, A4.02 A5.01 Details A5.01, A5.02, A5.03 A6.01 Schedules A6.01, A6.02 A7.01 Interior Design A7.01, A7.02 Other discipline prefixes: G -- General (project-wide cover sheets, code analysis) C -- Civil L -- Landscape S -- Structural M -- Mechanical P -- Plumbing FP -- Fire Protection E -- Electrical 1.3 Drawing Scale Conventions by Sheet Type Sheet Type Common Metric Scale Imperial Equivalent Site Plan 1:200 or 1:500 1" = 20' or 1" = 40' Floor Plans 1:100 or 1:50 1/8" = 1' or 1/4" = 1' Reflected Ceiling Plan 1:100 or 1:50 1/8" = 1' or 1/4" = 1' Roof Plan 1:100 or 1:200 1/8" = 1' or 1/16" = 1' Exterior Elevations 1:100 or 1:50 1/8" = 1' or 1/4" = 1' Building Sections 1:100 or 1:50 1/8" = 1' or 1/4" = 1' Wall Sections 1:20 or 1:10 3/4" = 1' or 1-1/2" = 1' Enlarged Plans 1:50 or 1:20 1/4" = 1' or 1/2" = 1' Interior Elevations 1:50 or 1:20 1/4" = 1' or 1/2" = 1' Construction Details 1:10 or 1:5 1" = 1' or 3" = 1' Stair/Elevator Details 1:20 or 1:10 1/2" = 1' or 1" = 1'
