Any test that yields valid data is a valid test.”      Adam Savage, Mythbuster   Intended Laboratory Manual Use This laboratory manual is intended to be used across one semester in the course CIVE 2261: Lab for CIVE 2260 offered by the Department of Civil and Environmental Engineering at Northeastern University in Boston, Massachusetts. This course is intended to be taken concuently with CIVE 2260: Materials for the Built Environment. The laboratory exercises provide hands-on, experiential understanding to complement the theory and concepts discussed in CIVE 2260. Details neglected herein are assumed to be presented either in class or in lab via lecture. Note also that the labs listed herein are subject to revision at the behest of the instructoprofessor.Laboratory Overview In this class, you will be introduced to standard laboratory procedures for materials testing, data reduction and data analysis methods.  This manual is comprised of five laboratories; however, the instructoprofessor may adjust this number. Laboratory methods and determinations covered in this manual include: uniaxial tension, concrete mixing and testing, fracture analysis, and flaw tolerance. The operation and use of computer-based test control and data acquisition systems are also covered.  Each lab will consist of a short lecture/introduction, conducting a lab test (or tests), and clean-up. The labs should be readily completed within the allotted time period.  Cuently, the labs are designed for group work and group lab reports. Confirm with your instructoprofessor.  By participating in this laboratory and completing the assignments, you will gain experience preparing laboratory reports using effective technical writing skills, including graphic presentation of data.Laboratory Objectives The primary objectives of the Materials for the Built Environment Laboratory are as follows: 1. Apply accepted standards (i.e., ASTM Standards) related to laboratory testing of materials to determine mechanical properties. 2. Demonstrate knowledge of the basic principles of stress and strain and how they relate to test esults and overall material performance. 3. Explain different failure modes (e.g., ittle vs. ductile, fracture), flaw tolerance and material toughness. CIVE 2261 Lab Manual    ii | F r o n t  M a t t e r   4. Explain how to design concrete mixes for particular applications, including the effect of water content. 5. Explain how to mix concrete and prepare specimens for strength testing. 6. Write effective technical reports to communicate the results of their laboratory testing, including preparing effective graphics.CIVE 2261 Lab Manual    iii | F r o n t  M a t t e r   Table of Contents  Preface ..........................................................................................................................

• Brief description/intro of surveying labs
Surveying is primarily utilised to fix the national and state boundaries, chart coastlines, navigable streams and lakes, establishing control points, execute hydrographic and oceanographic charting and mapping, prepare topographic map of land surface of the earth, prepare plan or map of the area surveyed, collect field data, analyse and to calculate the field parameters for setting out operation of actual engineering works. Moreover, during execution, project of any magnitude is constructed along the lines and points established by surveying. Thus, surveying is a basic requirement for all Civil Engineering projects.
Part 1: Leveling
• Brief introduction of leveling
Levelling is a method of surveying used for determination of the difference of elevations or levels of various points on the surface of the earth. The elevation of a point is its' vertical distance above or below a reference level, called datum. The most commonly used datum is the mean sea level (M.S.L.). The levelling deals with distances in a vertical plane. 
Levelling is an important method of surveying for many engineering works and construction projects. Levelling is required to determine the undulations of the earth's surface for topographic mapping. Levelling is needed for the design of highways, railways, canals, sewers, etc., and for locating the gradient lines. 
Levelling is essential for the layout of construction projects, for locating the excavation levels, and for the control of various elevations in buildings, bridges, dams, etc. The drainage characteristics of the area can be obtained by levelling, The results of the levelling can be used to determine the catchment area, volume of the reservoir and the area submerged by a reservoir. The results of levelling can also be used to determine the volume of earthwork for roads, railways, etc.
• Brief description of procedure 
1. Instrument level is setup at convenient positions near first point (say A).
2. Temporary adjustments should be done, (setting up, leveling up, elimination of a parallot) are Performed. 
3. First sight of B.M (point of known elevation) is taken and reading is entered in back Sight column. 
4. If distance is large instrument is shifted,
