Scope of Works
Scope of works comprises the following tasks to be completed: The Phase -1 project comprises Terrace villas-6nos, Duplex Villas-1 no., Forest Villas-3
nos., Sky Villas-2 no’s, Wine Cellar, Cigar Lounge, Butler Huts-2 no’s and shop building.
The Phase -1A project comprises Arrival Centre, Duplex villas, Garden villas, Terrace

The SPA Project Contains ayurvedic-1, ayurvedic-2, signature-1, signature -2, Beauty
and pampering block, Arrival building, BOH for staffs and Tibetan singing bowl building
which is constructed by Natural Stones with RCC Structures.
Earth retaining structures like Stone masonry wall, Gabions wall & RCC Shear Wall are
also constructed as per site conditions. Landscaping Location at Project Site
The project is being constructed in mountainous terrain ,so Landslide is the major issue for this
project .If landslide occurs here then Soil stability of land is totally unbalanced that makes
existing structures weak.
Major landslides occurred in this project due to heavy rainfall, which are:-
Phase-1A:
1.) Behind arrival center,
2.) Under swimming pool area occurs in 15 th Aug 2017,
3.) Under BOH-A/BOH-B Buildings,

Preventive Structures for affected areas with total Cost:
For Safety Purpose to prevent Massive land sliding problems in project we are constructing
Earth retain structures in affected areas. Types of Earth retain structures and their estimated
costs are described below:
In Phase -1A project, to prevent land sliding behind Arrival Building area, Shear wall was
Constructed which estimated cost is Rs. 491111.60
To prevent land sliding under swimming pool area, Gabion wall is constructing which
estimated cost is Rs 7142910.00
To prevent land sliding under BOH-A & BOH-B area, Stone masonry retaining wall will be
construction which estimated cost is Rs 6894527.50
Debris removal from Bathroom and changing room plinth slab ,due to landslide from BOH
Buildings .Which estimated Cost is Rs 44000.00
To prevent land sliding behind plot-27& plot-28 area, Stone masonry retaining wall will be
construction which estimated cost is Rs 4923105
Similarly to prevent land sliding at ABR Chamber, Shear wall is constructing for this estimated
cost is RS. 2080066.025
In SPA Project, behind signature-1 & singnature-2, stone masonry retaining wall will be
construction which estimated cost is Rs. 2867155.00
And at arrival Building-SPA, stone masonry retaining wall will be construction which estimated
cost is Rs 1026058.75
Therefore; the Gross Amount expenses to construct structure is Rs 25468934.00
