2.0 INTRODUCTION

MAIN BUILDING NATIONAL INSTITUTE OF TECHNOLOGY, CALICUT

CONSTRUCTED: 1962

INVESTIGATION: 2015 TYPE OF STRUCTURE: 3 STOREYED STONE MASONARY WITH RCC COLUMNS, BEAMS AND SLABS

The main building is located at the end of Rajpat Road in the NITC campus located, 22 kilometres (14 mi) north east of Kozhikode, formerly known as Calicut, on the KozhikodeMukkam Road. This was the first building constructed for the Regional Engineering College established in 1961 and has moved on to be a part of the National Institute of Technology Calicut from 2002.

The building now houses the campus network center, sports office, survey lab, computer networking lab, thermodynamics lab, computer intelligence lab, security office and several class rooms. The building although showing distresses, it has stayed strong for the past 53 years. The most weathering conditions the building has faced are the alternate drying and wetting by the weather pattern of Kerala.

The building spans 65m long building, built in three sections which are separated with expansion joints of 3cm. Its a framed structure with RCC columns, slabs and beam. The walls are built of stone masonary and are exceptionally strong and havent shown any signs of distresses or cracks.

3.0 DEVELOPING THE BUILDING PLAN The Main Building is a 65m long building, built in three sections which are separated with expansion joints of 3cm. The plan for the three storey was developed on Autocad, dividing each into the west wing and east wing. The location of the cracks were numbered and marked on the plan. The plans are attached in the following pages.

4.0 CLASSIFICATION OF CRACKS The cracks in the building here are broadly classified into structural cracks and superficial cracks. They can again be classified as active cracks or dormant cracks. The cracks found in the building were structural cracks which are active as long as the weathering conditions prevail. These cracks were again classified as Class A, Class B, Class C and Class D depending on the severity of the crack and their remedial measures to be adopted. The specifications for the classification are given below in Table 1. The location and classification of cracks is provided in Appendix 11.4.
