1. Structural Requirements

1.1 Foundations

The building foundation is crucial for ensuring overall stability and longevity. It must be constructed using high-quality reinforced concrete with specific performance standards as outlined below:

Component	Material	Specification
Piling	Concrete	Minimum 3000 psi
Footings	Reinforced Concrete	Minimum depth 1.0 meter

Piling: Concrete used for piling must achieve a compressive strength of at least 3000 psi to support the structure adequately.

Footings: Reinforced concrete footings are required to have a minimum depth of 1.0 meter to ensure proper load distribution and stability.

1.2 Superstructure

The superstructure, comprising floor slabs, columns, and beams, must adhere to stringent structural integrity standards:

Component	Material	Specification
Floor Slabs	Reinforced Concrete	Minimum 2500 psi
Columns	Reinforced Concrete	Minimum 3000 psi
Beams	Reinforced Concrete	Minimum 3000 psi

Floor Slabs: Must be constructed with reinforced concrete having a minimum compressive strength of 2500 psi to support the building's load.

Columns: Reinforced concrete columns should meet a minimum compressive strength of 3000 psi for structural stability.

Beams: Must also be made of reinforced concrete with a minimum compressive strength of 3000 psi to ensure they can bear the expected loads.

2. Electrical Requirements

2.1 Power Supply

The power supply system must comply with local electrical codes and be installed by certified professionals. Key specifications for the power supply components are as follows:

Component	Specification
Main Switchboard	Rated for 400 amperes
Electrical Wiring	Minimum 12 AWG copper wire
Grounding	Grounding rods with a resistance of less than 5 ohms

Main Switchboard: Must be rated to handle 400 amperes to ensure it can manage the building’s electrical load.

Electrical Wiring: Wiring should be at least 12 AWG copper to ensure safety and efficiency.

Grounding: Grounding systems must use rods with resistance below 5 ohms to ensure effective grounding.

2.2 Lighting

Lighting systems must provide adequate illumination throughout the building, meeting the following criteria:

Area	Illuminance Level
Offices	500 lux
Corridors	200 lux
Storage Areas	150 lux

Offices: Require an illuminance level of 500 lux for adequate visibility and productivity.

Corridors: Should have lighting providing 200 lux to ensure safe passage.

Storage Areas: Minimum 150 lux to facilitate easy access and identification of items.

3. HVAC Requirements

3.1 HVAC System Design

The HVAC system must be designed to provide optimal indoor air quality and thermal comfort. Specifications for HVAC components include:

Component	Specification
Air Handling Units (AHU)	Minimum 1000 CFM per unit
Filters	MERV 13
Thermostats	Programmable with setback capability

Air Handling Units (AHU): Each unit should handle a minimum of 1000 CFM (cubic feet per minute) to ensure efficient air distribution.

Filters: Must have a Minimum Efficiency Reporting Value (MERV) of 13 to effectively capture airborne particles.

Thermostats: Should be programmable with setback capability to optimize energy use and maintain comfort.

3.2 Ventilation

Ventilation systems are essential for maintaining indoor air quality and must meet the following airflow standards:

Area	Air Changes per Hour (ACH)
Offices	4 ACH
Restrooms	10 ACH
Kitchens	15 ACH

Offices: Require 4 air changes per hour (ACH) to ensure adequate ventilation.

Restrooms: Must have 10 ACH to manage humidity and odors.

Kitchens: Require 15 ACH due to high levels of steam and cooking fumes.

4. Plumbing Requirements

4.1 Water Supply

The water supply system must deliver potable water with sufficient pressure and flow rates. Key specifications are:

Component	Material	Specification
Main Water Pipe	PEX/CPVC	Minimum diameter 1 inch
Shut-off Valves	Brass	Installed at every fixture

Main Water Pipe: Should be made of PEX or CPVC with a minimum diameter of 1 inch to ensure adequate water flow.

Shut-off Valves: Brass valves must be installed at every fixture to allow for easy water shutoff and maintenance.

4.2 Drainage

The drainage system must effectively remove wastewater and prevent blockages. Specifications for drainage components include:

Component	Material	Specification
Drain Pipes	PVC	Minimum diameter 4 inches
Traps	U-trap	Installed at every fixture

Drain Pipes: Must be made of PVC with a minimum diameter of 4 inches to handle wastewater effectively.

Traps: U-traps should be installed at every fixture to prevent sewer gases from entering the building.

4.3 Fire Suppression

An automatic fire suppression system must be installed throughout the building, meeting the following requirements:

System Components: Should comply with the latest fire safety standards and be designed to protect all critical areas of the building.

Coverage: Ensure comprehensive coverage, including high-risk areas such as kitchens and electrical rooms, to maximize fire safety.
