Abstract

The fostering IT sector in Hyderabad has developed a demand for new residential accommodation in the city of Hyderabad. The suburban and urban areas of the city have been witnessing a rise in number of new housing projects. This has lead to the change in the dynamics of the valuation of the housing units in the city. In this study, an attempt has been made to value the housing units based on its intrinsic and extrinsic characteristics. To do so, the Hedonic Pricing concept has been used which is based on the multiple regression techniques to regress the pricing function and to study the individual as well as the overall effect of the characteristics on the value of the property. Factors that determine the house prices in Hyderabad are analyzed in this study using data collected from various sources such as the property expo, site sales office, sample flat visit and company's website. Data collected for 20 gated housing units in different areas of Hyderabad has been used to generate the model. The results showed that the following variables were significant: number of stories, proximity to bus stand and railway station, number of rooms and whether the house is ready to move or not. They accounted for 88.44% of the variations. The Hedonic Pricing concept is thus used to model the relationship between the sale price of a house and the housing attributes which will prove as a basis for any real estate transaction for a project developer, a house buyer, loan granting banks and insurers.

Abstract

Precasting might not be a new technique in the construction industry but it is gaining its importance with respect to Project schedule and costs. To create better and improved facilities, government has taken up many projects to complete in shorter duration. In the trial of completing the projects, engineers advise to opt the precast technology. Precasting may be defined as a process of casting the concrete elements away from actual construction to the required specification and dimensions and it is economical if the number of elements is in multiple hundreds. In this case study, precasting of H- frame is considered and it is as per defined scope. During the course of execution it was observed that the process was on time, but due to revised schedules, the productivity was low. But in the course of time the productivity was enhanced from one precast H-Frames per week to three precast H-Frames per day. This was possible only with proper site layout, proper site operations and proper stocking.

Keywords

Abstract

The new Austrian tunneling method (NATM) is widely applied in design and construction of underground engineering projects. The NATM is also known as sequential excavation method (SEM). The NATM is a construction method, which is very adaptive according to changing subsoil conditions and changing shapes of cross-sections. NATM/SEM enhances the self-supporting capacity of the rock or soil by mobilizing the strength of the surrounding ground. It is today by far the most resistant tunnel support system in earthquake endangered zones. Experience from past projects has helped to identify several critical success factors for safe and cost effective NATM/SEM tunneling. According to actual site conditions the design of NATM is with a certain degree of flexibility for adjustments .Unit price contracts to support flexibility, adaptability and balance risk sharing - a proven way to a cost effective and state-of-the-art product. Skilled contractors are familiar with the principles of NATM/SEM and the utilization of the ground support measures. Basic idea behind NATM is that immediate rocks are self-supporting and this method is economical. Here the cycle time achieved is 12 hrs. for class I, II and III but for the rock classes IV and V the cycle time achieved normally is 16-18 hrs. The NATM is most appropriate support system for tunneling in soft ground i.e. rock class IV and below. The installation of reinforced lattice girder with wire mesh, shotcrete and rock bolting provides a uniform load bearing structure in soft rocks.
