Electrical and Plumbing Services – Drawing Requirements
The project requires detailed electrical and plumbing service drawings for a single-story guesthouse development consisting of five guest rooms, one master bedroom, reception/lounge area, kitchen, café space, laundry area, and swimming pool.
Electrical Services
Electrical drawings should include a complete layout of the building’s electrical distribution system. The building will operate on a three-phase power supply with the main meter and incomer located near the garage wall facing the reception area.
Two distribution boards will be used:

The electrical drawings should include:
- Lighting layout for all rooms, corridors, and outdoor areas
- Socket outlet locations and switch panel positions
- Air conditioning power points for all rooms
- Ceiling fan locations
- Exhaust fan locations for bathrooms
- Wiring routes with concealed conduits within walls and slab, and surface conduits above ceiling gaps where necessary
- Cable routing for the main underground supply from the meter to distribution boards (approximately 65 ft)
- Earthing system layout
- Provision for future rooftop solar PV system integration
All electrical components should be designed for safe operation in a tropical island environment.

All plumbing should use standard PVC or PPR piping systems suitable for long-term durability in island conditions.
Structural Design – Drawing Requirements
The project requires structural drawings for a single-story guesthouse development consisting of five guest rooms, one master bedroom, reception/lounge area, café space, kitchen, laundry area, and a small swimming pool.
The building will be constructed using reinforced concrete foundations with cement block wall construction and a steel roof structure.
Foundation System
Structural drawings should include a continuous reinforced concrete foundation system supporting all load-bearing walls and columns.
Key requirements:
- Continuous foundation beam approximately 8 inches width and 10 inches depth
- Total foundation length approximately 606 feet
- Reinforcement using 10 mm steel bars with 6 mm binding rings
- Individual column footings approximately 18” × 18” × 8” for load-bearing columns
- Proper reinforcement layout and spacing for foundations and columns
Columns and Structural Frame
The building includes:
- 12 reinforced concrete load-bearing columns
- Maximum column size approximately 10” × 10”
- Additional non-load-bearing wall columns integrated with masonry walls
- Reinforced concrete beam running above wall level to tie the structure together
Structural drawings should show:
- Column grid and positions
- Beam reinforcement details
- Connection between columns, beams, and masonry walls
Wall Construction
Walls will be constructed using standard cement blocks (12” × 6” × 6”) with cement mortar. Walls will be plastered on both sides with approximately 12 mm cement plaster finish.
Structural drawings should include:
- Wall layout and thickness
- Reinforcement where required
- Beam support above wall openings such as doors and windows
Roof Structure
The roof will be a sloped lightweight steel structure supporting metal roofing sheets.
Key requirements:
- Structural frame constructed using galvanized steel square pipes (approximately 4” × 2”)
- Main steel members spaced approximately 4 feet apart
- Cross members installed to create a grid structure for roof sheet support
- Roof slope from approximately 15 feet height at the rear wall to 11 feet height at the front wall
- Roof length approximately 116 feet
- Roof projection approximately 1 foot beyond exterior walls
Structural drawings should include:
- Steel roof framing layout
- Member spacing and connection details
- Roof sheet fixing system
Swimming Pool Structure
The project includes a small swimming pool approximately 10 feet × 6 feet with 4 feet depth.
Pool structure will include:
- Reinforced concrete slab approximately 4 inches thick
- Reinforced block walls tied into slab and ring beam
- Overflow slot with gutter system along one side
- Pump and filtration system connected to pool circulation piping
Structural drawings should include:
- Pool slab reinforcement
- Wall reinforcement
- Overflow channel and drainage system
- Pool equipment space and pipe routing
General Structural Requirements
All structural elements must be designed to ensure durability and stability under island environmental conditions including humidity, salt exposure, and heavy rainfall. Materials and reinforcement should follow standard structural engineering practices suitable for low-rise reinforced masonry construction.
