Schematic drawing :

SCHEMATIC BUILDING PLAN — KEY DETAILS & COMPONENTS

A schematic building plan (also called a schematic design drawing) is the early-stage architectural drawing that shows the basic layout, relationships, and major elements of a building before detailed construction documents are developed.

✅ 1. Essential Elements of a Schematic Building Plan

1. Floor Layout

• Overall building shape / footprint
• 
  
• Room or space locations
• 
  
• Circulation paths (corridors, lobby, halls)
• 
  
• Entry and exit points

2. Room Labels

Each room should include:

• Room name (e.g., Living Room, Office, Bedroom 1)
• 
  
• Optional: approximate area (m² or ft²)

3. Wall Types (Simplified)

Indicated using:

• Thick lines → Exterior walls
• 
  
• Thin lines → Interior partitions
• 
  
• Dashed lines → Proposed changes or overhead elements

4. Door & Window Placement

• Doors drawn as arcs showing swing direction
• 
  
• Windows represented with thin rectangles or breaks in walls
• 
  
• Provide approximate widths

5. Dimensions (Schematic-Level)

Not fully detailed — just:

• Overall building dimensions
• 
  
• Key room sizes
• 
  
• Circulation width (e.g., corridor width)

6. Structural Elements (Basic)

• Column grid (if applicable)
• 
  
• Major shear walls or load-bearing walls

7. Plumbing and Wet Areas

Toto spares, Toto parts, Toto spare parts, Spare code no : TCM1158-2 - asst operating substrate assy.

• There is a listing for TCM1158 described as (which translates from Japanese very roughly as “auxiliary control substrate assembly”).
• The “-2” suffix likely indicates a variant (revision, colour, region spec) of part number TCM1158.
• It appears to be a circuit board/ control board associated with TOTO electric toilet / washlet parts, rather than a purely mechanical part.
• It is listed on Japanese retail-site (Rakuten) under TOTO with part number TCM1158.
• A Taiwan TOTO parts list shows TCM1158 described as (auxiliary IC) for model TCF812T etc.
• The full specification (e.g., exact dimensions, connector type, wiring, whether it includes buttons, LEDs, etc) is not publicly detailed in my search.
• “ASS’T OPERATING SUBSTRATE ASSY” suggests it is a “sub‐assembly” (i.e., board + perhaps components + connectors) but exact function in the equipment is not clearly documented in the public listings I found.
• Whether “-2” means a particular revision, colour code, region variant, or compatible model list is not clear from available listings.
• No official TOTO English spec sheet for TCM1158-2 that I found so…

Roof Slab Plan :

A Roof Slab Plan is a critical drawing that shows the topmost RCC slab layout, including its beam arrangement, openings, slopes, drainage points, reinforcement notes, and any architectural or service features.

🏗️ 1. What Is a Roof Slab Plan?

A roof slab plan (also called an RCC slab layout or terrace slab drawing) shows:

• The layout of beams and slabs at roof level
• 
  
• The direction of slab reinforcement
• 
  
• Drainage slopes and outlets for rainwater
• 
  
• Any openings (like staircase, skylight, water tank base, ducts, etc.)

It’s usually drawn by a structural engineer after architectural plans are finalized.

📄 2. Purpose of Roof Slab Plan

• To guide formwork and reinforcement placement during construction
• 
  
• To locate drainage points and ensure proper roof slope
• 
  
• To coordinate service openings (plumbing, electrical, solar, etc.)
• 
  
• To check beam positions and load transfer
• 
  
• To serve as the as-built reference for waterproofing, insulation, and finishing

Centerline Drawing :

1. What Is a Centerline Drawing?

A centerline drawing (also called a setting-out plan) shows the exact center positions of all structural and partition walls, columns, and footings in a building.

It is used by engineers and site supervisors to mark and locate the structure accurately on the ground before starting excavation or foundation work.

👉 It acts as the reference drawing for all other construction drawings (foundation, footing, and wall layout).

📐 2. Purpose of a Centerline Drawing

• To locate footings, columns, and walls precisely on site.
• 
  
• To mark intersection points (grid lines) that define the structural geometry.
• 
  
• To ensure alignment and symmetry of the building.
• 
  
• To minimize errors in excavation and RCC foundation placement.
• 
  
• To provide reference for all vertical elements (columns, walls, etc.).
