India’s construction industry is an important development indicator, as it creates opportunities for investment across numerous connected sectors. Today, fast track construction is a fast-growing economy, with rising costs and therefore time savings in construction can compensate for vital proportions of overall construction costs. This paper presents a study on time and cost-wise feasibility between two construction systems, Structural Steel and Concrete, precast concrete construction. A case study considered for this work is a 16-storied building, which consists of six stilt floors meant for parking, and the rest of floors are meant for office space. The Primavera P6-2017 used for time scheduling and the optimum time required at different stages of all these two buildings are cal- culated. The cost of structure is calculated considering the above two systems of construction and details presented here with. On the time basis, the composite structure will be an option for the client as it will reduce the time about 33 days and coming to the cost point of view structural steel is a bit of cost mate- rial. While coming to the precast structure it may take more than the time required for the composite structure, but cost analysis reveals that it will be economical than composite structure.

Introduction The introduction of the hot-rolled steel section and the cold- formed steel section has made the biggest revolution in the con- struction of high-rise buildings. Composite sections will present a significant economy to the system. The popularity of the steel- framed construction has increased over the last two decades due to the advantages of using the composite structure [1–3]. In recent years, there is a significant development in the con- struction industry i.e., Precast concrete construction. It is an alter- native construction technique. Cast in situ is a methodology where the concrete is casted in its actual location. While coming to pre- cast, it will be cast in another location either at the building site or in a factory, transported to location and connects individual elements. Precast concrete elements are connected at a joint by in situ casting [4]. Sometime junction grouting is done for the elements [5,6]. Primavera is an Enterprise Project Portfolio Management (EPPM) [7,8] software, which covers scheduling, risk analysis, pro- ject management, resource management [9] and integration with other enterprise software such as Oracle and SAP ERP systems. About the project The building in the case study is entirely a 16-story composite steel structure. It has rectangular (47 m  69 m) in plan with a height of 63.5 m (Height of Ground floor is 6 m, Height of Typical stilt floor is 3.25 m and Height of typical office floor is 3.8 m) and gross floor area is about 53000 m2 (3312 m2 at each floor), proposed at puppalaguda Hyderabad. Figs. 1 and 2 shows the plan layout of the structure with columns. Considering the same design, floor-to-floor height, loading condition, and total floor area, another model is proposed in the precast concrete construction method. As the project is mainly dependent on client require- ments. As per the Client requirement, the Client needs about mate- rial details only. Once the material details are in, the client will discuss it with the contractor regarding the workforce and equipment required. https://doi.org/10.1016/j.matpr.2020.03.742 2214-7853/Ó 2020 Elsevier Ltd.
