Dear Lester,
It depends on the hotel that your building.
The main activities would be

1) Civil works: Excavation, foundations, SOG, floors and roof, insulation, backfilling, Swimming Pools and Jacuzzis, treatment plants

2) Electro Mechanical works: Depends on each area. Basement you will have the Boilers, Water tanks, laundry, mechanical rooms, and electrical rooms. Ground floor your will have the reception, restaurants, stores, ballrooms, and the floors you will have the rooms and the corridors. You will have at least 15-25 systems in this category depending on the complexity of your hotel.

3) Finishes works will be for each area in the hotel. But once you have the mock up room approved, the majority of your finishes will be completed.

4) Kitchens, Laundry, landscape works with plants and irrigation, movable furnishers, sign age, sanitary fixtures and toilet accessories, art work, access roads, dorms for our staff, etc

If you have specific questions, please let me know.

Good luck.

Samer
