2.
Prefabricated Prefinished Volumetric Construction (PPVC) is a construction method whereby freestanding 3D modules are completed with internal finishes, fixtures and fittings in an off-site fabrication facility, before it is delivered and installed on-site. The whole idea is to significantly speed up construction in this traditionally manpower-intensive industry. In this dissertation work, a 3D RC bare frame structure having conventional beam column system and prefabricated prefinished volumetric construction system are compared with G+10, G+20 and G+30 stories by performing FE analysis involving modal, equivalent static, response spectrum analysis. The results of time period, base shear, storey displacements, storey drifts are obtained. All the results are tabulated, discussed and conclusions are drawn.

PROBLEM FORMULATION AND ANALYSIS A detailed summary of the various parameters defining the Prefabricated Prefinished Volumetric construction (PPVC) and Regular frame system (RFS) with plan and vertical irregularities in each model is also presented. The methodology involved in computing some of these parameters is explained and important feature of the current provisions relating to earthquake resisting design of reinforced concrete lateral forces resisting system are presented.

1.INTRODUCTION Prefabricated prefinished volumetric construction (PPVC) is an innovative and cleaner approach that has restructured the production of the construction industry. It can improve the workflow continuity, increase the efficiency in the use of resources, minimize construction wastes, and reduce the number of on-site contractors as well as construction durations. While the benefits of PPVC have been widely recognized over the past two decades, the constraints on using PPVC remains unexplored.
5. PRESENT STUDY The present study adopts structural 3D models with different types of plan irregularity & vertical irregularity. The seismic responses of these Prefabricated Prefinished Volumetric construction building models have been compared with that of the Regular frame system building model. The base plan size has been kept as 30m x 30m.

3D RC frame with regular frame system and PPVC system are considered for seismic loading. PPVC connections are designed for seismic loading. FE Analysis of the structure is done by Modal, Equivalent Static and Response Spectra Analysis methods for both plan and vertical irregularities.
Detailed literature review is carried out on the Prefabricated Prefinished Volumetric Construction and Plan & Vertical irregularity.

3. METHODOLOGY 1.
The study is based on the analysis of structural models representing multi-storey buildings with regular frame system and PPVC system are presented and discussed in detail. Basically, six types of models G+10, G+20 and G+30 with regular frame system and PPVC system. For all seismic zones are considered, for each such building model is considered with critical soil types.
