Introduction
The architecture for a landmark is very much crucial as it helps to design and construct the necessary requirements while concerning a construction. In this present context, the application of Le Corbusier’s Architecture is more responsive that any other implementations. While concerning this present critical evaluation about the architectural context, the involvement of 5 principles by Le Corbusier’s is having the responsive attributes for delivering a well-designed architecture. The following assessment is with the inclusions of structural analysis, functional analysis, geometry considerations and providing a new structure for Villa Savoye (Poissy). On the other hand, there is the involvement of Employer Information Requirement (EIR), which is effective to have the information about the respective employees while working in Villa Savoye. However, the assessment is effective for providing an efficient and advantageous design or architecture for Villa Savoye.
Villa Savoye
In the year 1927, Le Cobusier has proposed some architectural designing framework that is effective for providing the necessary design as per the necessity for a specific construction. The present concern is with the enhancement of Villa Savoye for having an attractive design for the success in future. The 5 principles by Le Corbusier are very much effective that are illustrated below for better instance.
The Pilotis: The terminology Pilotis is specific for the awareness of a particular grid that is replacing load-bearing walls and is becoming the basis of new building. In this context, the substance of Villa Savoye has been elevated by the ground level and has the support by “pilotis” or some concrete stilts that were reinforced before.

In case of material properties of this building, the following calculations should be taken into account-
Concrete
All the components should be specified unless the design will be M25 grade all
Ec = 5 000 (sqrt(fck)) N/mm2 = 5 000 (sqrt(fck)) MN/m2
= 25000 N/mm2
= 25000 MN/m2
For the central columns, which are up to the plinth, including ground floor and first floor, M30 grade will be applied-
Ec = 5 000 (sqrt(fck)) N/mm2 = 5 000 (sqrt(fck)) MN/m2
= 27386 N/mm2
= 27836 MN/m2
Functional Analysis
Weight Calculations
In this planning, the seismic weight can be calculated in an appropriate manner based on the gravity loads (Devadiga, 2017). The columns and walls’ weight for any storey must be equal to the distributed floors up and under the storey. The following minimized live loads can be applied for the analysis of Zero terrace and it is 50% above other floors.

Table 3: Storey 1 weight calculation
Therefore, the seismic weight for the entire building = 6 138 + 2 027
= 8 165 kN
Designing the Seismic Load
In the upper floors, the infill walls should contain a large opening though the solid walls can be considered as the most crucial part of load calculation. Therefore, the basic time T can be obtained thorough applying the following formulae-
Ta = 0.0075 h0.75 [according to the IS 1893 (part I): 2002, including the Clause 7.6.1]
= 0.075 * (30.5)0.75
= 0.97 sec
In case of the Zone Factor, Z = 0.16 for the Zone III [following IS: 1893 (part I): 2002, table 2]
In this context, Importance Factor, I = 1.5 (for the public building)
Sa / g = (1.36 / 0.97) = 1.402

Geometrical Analysis
From the above-mentioned layouts, it can be analysed that the building includes floor beams, FB at the ground floor, which are of 100 mm under the ground. The numbering of geometrical analysis can be explained as follows-
Storey Number
Portion of the building
Storey Number
Ground Floor – Foundation top
1
First floor – ground beams
2

Column Number
From the above figure, it can be stated that the columns from C1 to C8 can be numbered in a sequential way from the left to right, as well as it is from the upper to the lower part of the plan (Ciribini et al., 2016). The column C5 is called as the footing of terrace level and it can be differentiated from the column lengths in various stories. The column lengths are known to 105, and 205. The very first digit depicts about the storey number when the last two numbers indicate the column number. It can also be highlighted through the grid lines.
Floor Beams (Secondary Beams)
The floor beams are capable of free revolution, which are known as FB and mentioned in the above figures. All the reactions in this floor beams can be calculated manually and this act as the point load of these main beams. However, all these floor beams cannot be considered as the segment of this space frame modelling.
Main beams number
The beams that are passing through columns can be termed as the primary beams and all of those together including the columns can form the space frame. The basic layout of above-mentioned figure can be numbered, as the primary beams as B1 to B12 are the most convenient process those are in the left to right direction and lower to upper part of the main building. In order to provide a 90 degree based clockwise rotation for this plan, it can be marked sequentially as the beams based in perpendicular direction. For differentiating floor-wise based on the floor plan, the beams can be numbered as 1005 and 2005. In this numbering, the very first digit denotes beam number, which can be found as basic layout of the building. Therefore, 2005 indicates the beams available in 2nd storey.

Le Corbusier ‘5’ points
Le Corbusier’s Villa Savoye can be summed up including the five points of architecture. At first, Le Corbusier lifted the huge amount of structure off the ground, which can be supported by the piloti, including the reinforced concrete stilts. Before starting the career, Le Corbusier implemented a group of architectural rules, which dictated this specific technique that is called as “Five Points of New Architecture” (Alhava et al., 2015). These all are considered as the most effective evident in his Villa Savoye.
Pilot-is: This is considered as the replacement to support the walls through a grid of “Reinforced Concrete Columns”, which bears the main structural load on the basis of this innovative aesthetic.
Facade free designing is aimed to separate the building’s exterior from the structural function, which can be set as the facade free from this structural constraints (Taranath, 2016).
The basic and free designing of the “Ground Plan” is based on supporting the absence of walls that means the entire house should be unrestrained in for its internal application.
In case of the horizontal window, it helps to cut the facade including its entire length for lighting up the rooms equally.
In case of the Rood Gardens over a flat roof, it can be served as a domestic purpose for providing the necessary protection for the concrete roof.
Project EIR
EIR (employer Information Requirements) can be defined as the information needed by the employer from both suppliers and internal team for developing the project and for operating in such a way to create asset (Eastman, 2018). There are several relevant extracts, which help to identify the EIR, including the PD (procedure Documents) for appointing every supplier, who are employed by the employer can include consultants, advisors, contractors and others.
Conclusion
By evaluating the above analysis, this can be concluded that the use of Le Corbusier’s model for providing an architectural design is very much effective. In this present context, the esteem concern that is to design the architectural design of Villa Savoye is designed with the help of Le Corbusier’s model by maintaining the necessary 5 principles. For instance, the Ground Plan for Villa Savoye can be more responsive by the involvement of Le Corbusier’s model. On the other hand, the Facade free designing is advantageous for having the awareness of structural constraints. Moreover, the Roof Gardens of the building can be possibly constructed by implying the Le Corbusier’s model with proper approaches. Apart from all of these, the assignment is with the inclusions of functional analysis and geometry considerations, which are effective in terms of effective designing of Villa Savoye.
