User: I want you to act as a seasoned engineer / house builder / contractor.

I want you to act as a seasoned engineer / house builder / contractor. I want you to prepare a detailed bill of quantities for a kitchen to be built as an add on to an existing house. separate costing for materials and labor.

the size of the kitchen is 2 meters in length x 5.4 meters wide.

the flooring will be covered by tiles (estimate Php7,040 from Wilcon).

the ceiling will be covered with pvc ceiling panel (estimate Php4,040 from Wilcon)

a 0.63m x 3.55 countertop will be built inside - use best value laminate from Wilcon.

50cm*40cm single kitchen sink undermount.

the walls will remain bare and simply painted over.

side door will use a sliding door 120cm wide, 210 cm tall (estimate Php11,716)

use p. tech corrugated Asa roof sheet (Php2,150 per sheet, sheet size 1.5mmx1.13mx12ft - estimate required roofing).

feel free to replace the materials if you find a better priced one - just make sure to include the link to the product.

the kitchen has no windows. only opening is the sliding door at the side and the adjoining dining room. note that the wall between the kitchen and dining room could be demolished depending on the price.

CHB for walls. Slab on Grade as foundation type. Lean-to roof structure. no need to add heater to water supply. distance to main line is between 12 to 12.5 meters. no need for grease trap. range hood for cooking fumes. light fixtures/outlets and dedicated circuits for appliances.

make sure to include estimates for masonry, plumbing and electrical works. ask me if i missed anything and if i want to include it. add export button to the BOQ. optimize costing for construction located in Bocaue, Bulacan.

Great — before I generate a full detailed Bill of Quantities (BOQ) with separate material & labor costing optimized for Bocaue, Bulacan, I need a few clarifications so the estimate is accurate and complete.

Please answer the following:

1. Wall Height What is the wall height from floor to ceiling? Example: 2.4m, 2.7m, 3.0m

1. Wall Between Kitchen & Dining Room Do you plan to demolish the wall entirely, or keep it with a door opening only? If yes: approximate width of opening?
2. Wall Finish You said “bare & simply painted” — do you want smooth plaster & paint, or textured finish? Plastering affects cost.

1. Side Sliding Door Material Prefer aluminum frame with glass, vinyl, or steel?

1. Threshold / Security Grill Needed or none?

1. Water Source - Will this connect to existing household water line? - Need new water line trenching? If yes, approximate route length beyond the 12–12.5m?

1. Drainage - Do you already have a sewer line near the kitchen? - If not, need new sewer/drain line installation?
2. Faucet Budget range? Standard lever / pull-out / branded?

1. Number of Light Fixtures - Ceiling lights / task lights (over countertops)? Estimate: None / 2 / 3 / 4

1. Outlets How many? - General outlets - Dedicated circuits for: refrigerator, range hood, microwave, rice cooker

1. Do you want allowances for the following?

• Range hood
• Cooktop (gas or electric)
• Built-in oven
• Refrigerator

If yes, preferred sizes & approximate budget per item.

1. For the 0.63m x 3.55m countertop:

• Do you want cabinet carcass included (wood + hardware)?
• Or just the countertop surface?

1. Laminate style preference:

• Standard
• Premium Wood-grain
• Stone look

1. Should labor rates include:

• Permit costs
• Waste disposal / dumpster
• Scaffold rental
• Tools & equipment rental (Check yes/no for each)

Would you like estimates for:

• Ceramic or metal backsplash behind sink/cooktop
• Exhaust vent ducting
