Abstract
“License to drive is not a license to kill”. The unscrupulous growing population has created many problems in country like India. One of the challenging ones being car parking which we confront almost every day. Besides the problem of space for cars moving on the road, greater is the problem of space for a parked vehicle considering that private vehicles remain parked for most of their time. While residential projects still escape with designated parking, the real problem lies with commercial spaces many a time which is overcome by taking extra open spaces to park.

Strength of concrete is commonly considered its most valuable property, although in many practical cases, other characteristics, such as durability and permeability, may in fact be more important. However, the strength of concrete is almost invariably a vital element of structural design and is specified for compliance purposes.

A simple method of concrete mix design for pumpable concrete based on an estimated weight of the concrete per unit volume is described in the paper. The tables and figures presented are worked out by the author from a wide range of Indian materials. The method is suitable for normal weight concrete with admixture.

INTRODUCTION
Pumped concrete may be defined as concrete that is conveyed by pressure through either rigid pipe or flexible hose and discharged directly into the desired area. Pumping may be used for most all concrete construction, but is especially useful where space or access for construction equipment is limited.

Most of our construction sites do not have field-testing laboratory. In this paper simple test methods of construction materials are described which could be performed without any machine or special equipments.

1. TEST FOR ORGANIC IMPURITIES IN FINE AGGREGATE
The aggregate must be checked for organic impurities such as decayed vegetations, humus, and coal dust, etc. Colour test is a reliable indicator of the presence of harmful organic matter in aggregates except in areas where there are deposits of lignite.

Procedure:
a) Fill a 350 ml clear glass medicine bottle upto 75 ml mark with a 3% solution of caustic soda or sodium hydroxide.

Throughout history, many great persons have made significant contributions the field of civil engineering. I tried to diversify this list of great civil engineers to include people of ancient and well as modern times. Also I have delved deeper into other cultures that have contributed so much to our knowledge base and development so as to include a diverse list. Please note that this list is not extensive, but I hope this gives you a better perspective of lives, accomplishments and impact these people have made in our field.Sir Mokshagundam Visvesvaraya is one such civil engineer.

General Requirements for Walking/Working Surfaces
1. Housekeeping – Facilities shall be maintained free of debris, clutter and moisturein order to eliminate slip, trip and fall hazards. Where cleaning or other temporary situations cause floors to be wet, signs or other warning devices shall be used to warn of the slip hazard.

2. Wet Process Locations – Where wet processes are used; drainage, false floors, platforms, mats etc. shall be used to provide for dry work surfaces.

1. Anchorages – An anchorage is a secure point of attachment for lifelines, lanyards or deceleration devices. Anchorages used for the purpose of fall arrest shall be capable of supporting at least 5,000 pounds (22.2 kN) per employee attached. Alternatively, a fall protection system may be designed, installed, and used as part of a complete personal fall arrest system which maintains a safety factor of at least two, under the supervision of a Qualified Person (certified anchor). Both are considered acceptable for fall protection so long as they meet the general requirements and the performance criteria specified for their type. General requirements for all fall arrest anchorages include:
i. Located as high as possible to minimize the free fall distance to and arresting forces to < 1800 pounds. (8kN).

ii. Located to prevent contact with obstructions or the ground below.

iii. Located directly over the working position whenever possible to minimize swing falls.

General Requirements for Performing Work at Heights
A. Duty to provide fall protection – Where employees are required or allowed to walk or work while performing assigned tasks on a shall guard by a standard railing or the equivalent, every open-sided floor or platform 4 feet (1.2m) or more above adjacent floor or ground level on all open sides except where there is entrance to a ramp, stairway, or fixed ladder. Additionally, the railing shall be provided with a toe board when beneath the open sides where; a person can pass, there is moving machinery or there is equipment with which falling materials could create a hazard. In situations where guarding requirements are not applicable because employees are exposed to falls from an elevated surface on other than a predictable and regular basis, personal protective equipment or another effective fall protection methods shall be provided.

Introduction – Ladders are a great resource to help workers access materials or work areas that are out of reach. Additionally, ladder accidents are one of the leading causes of occupational injuries and fatalities.

The proper precautions must always be taken. Employees should be able to recognize potential hazards associated with ladder use. Additionally, they should know how select the right ladder for the task, set up, and use ladders in accordance with manufacturer and site ladder safety requirements.

Introduction:There are too many line items in life which you cannot calculate. Gravity is one among them. When you lose your balance and fall that’s called as Gravity at work. Many people life at risk got injured or died due to fall from height during the job. Fall from height results in serious injury than any other accidents in the industry. People suffer from broken bones, spinal injuries, paralysis and few more after the fall from height.
