· Second Floor Level

· Level and replace subfloor and flooring.

· Modify and upgrade all railing systems to meet Embassy and code requirements.

Utility Systems or Systems Upgrades

· Make repairs listed in “BUILDING INSPECTION REPORT” by Tharuna Limited.

New work and adjustments, rebalancing, and commissioning of all the following systems:

· Perform upgrades as necessary utilizing OBO residential safety attachment, “Residential Safety Checklist V8 May 2025”.

· Structural (Reference J.3.1.3)

· Provide all necessary structural modifications to accommodate seismic upgrades, accessibility, and life safety requirements.

· Seismic reinforcement of the exterior structure and block infill on the patio.

· Mechanical

· Additional HVAC systems will be required on the first-floor corridor. Systems must be capable of operating in cooling and dehumidification mode. All new/replacement HVAC equipment to be provided with enhanced corrosion protection features. Include new electrical power infrastructure.

· Provide exhaust fans in all bathrooms. Include new electrical power infrastructure.

· Plumbing

· In addition to the plumbing repairs listed in survey report by Tharuna Limited, flush, clean and disinfect the hot/cold domestic water distribution piping with appropriate treatment means, suitable for the material of the existing water distribution system.

· Install whole house sediment backwash system.

· The main water storage tank is to be protected from the elements, sunlight and elevated ambient temperatures.

· The swimming pool and hot tub systems need to be surveyed and evaluated for code compliance using the Swimming Pool and Spa code. Overhaul and repair all pool and hot tub equipment, including controls, pumps, and filtration.

· Install sewer access cover in driveway to allow for routine cleaning of existing transition box approximately 5’ deep (marked with “X” on site). Incorporate design in driveway improvement project.

· Modify ground floor sewer piping to allow for proper flow from exterior washroom and interior maid’s quarters washroom.

· Electrical

· Complete electrical renovation – Based on the survey report by Tharuna Limited, the entire electrical system is old without any labels and schedules, missing GFCI receptacles, dated light fixtures and switches, overloaded panelboards.

· New circuitry to support new room layouts and equipment.

· Inspect and install proper grounding system. Install separate earthing and neutral bus. Add independent ground rod to new earthing bus for main electrical distribution panel.

· Inspect generator and controls for proper operation. On a non-running three phase or single-phase generator, use an ohmmeter to verify that no short circuit (low to zero ohms) exists between generator enclosure/frame/ground rod/connecting metal conduit/junction boxes and any phase conductor and all its interconnecting wiring to the building loads. For generators with a 3-pole Automatic Transfer Switch (ATS), there should be no bond between ground and neutral. The neutral-to-ground bond must be removed at the generator.

· Power quality study – to determine if an Automatic Voltage Regulator (AVR) is required or upgrade of electrical system capacity.

· Replace all deteriorated electrical light fixtures – Indoor and outdoor lightings.

· Provide all required electrical utilities and connections for the new guard booth, including power, lighting, communications, security system connections, and climate control.

Fire/Life-Safety

· Specialty fire extinguishing in commercial kitchen. Ansul wet chemical fire suppression system to be installed in the kitchen.

Security

1. Perimeter Wall- Design and construct a 9 ft high perimeter wall throughout the property, measured from the attack side, to considerably deter unauthorized access. Wall design to include anti-climb features such as spike strips or metal tubing as required by OBO security standards.

d. No additional requirements for the rear wall.

e. Add spike strips to south, east, and west walls.

2. Guard Booth- Design and construct a fully enclosed guard booth at the driveway entrance, designed to meet OBO security standards. The booth shall include all associated electrical utilities (power, lighting, communications, security system connections, and climate control as required).

a. Guard Booth will be located in the southwest corner of property near the vehicle gate, but north enough to clear the electrical pole and to not have the swing gate interfere with viewing panel of the booth.

b. Guard booth will be approximately 9’x 8’ and share a wall with the western wall.

d. A sliding glass window will face east and a door will face north.

3. Perimeter gates- Design and construct a perimeter pedestrian gate and a driveway gate, both to match the height of the perimeter wall and include anti-climb features. Pedestrian gate to include keypad access control, video/audio identification system, and an additional means of egress other than a key. Driveway gate to be equipped for remote opening or manual operation by on-site security, and both gates to be designed for substantial security and durability. Provide all construction details, hardware, and finishes.

a. Vehicle and pedestrian gate will be same height as front wall and have spike strips.

b. Vehicle gate will also have spike strips.

c. Vehicle and pedestrian gate will have sheet metal style louvres to prevent climbing and create privacy.

d. Pedestrian gate will have a keyed entrance and thumb turn exit or push button exit.

e. Pedestrian gate will have a programable keypad entrance.
