Many factors affect the amount of temperature-induced movement that occurs in a building and the extent to which this movement can occur before serious damage develops or extensive maintenance is required. In some cases joints are being omitted where they are needed, creating a risk of structural failures or causing unnecessary operations and maintenance costs. In other cases, expansion joints are being used where they are not required, increasing the initial cost of construction and creating space utilization problems. As of 1974, there were no nationally acceptable procedures for precise determination of the size and the location of expansion joints in buildings. Most designers and federal construction agencies individually adopted and developed guidelines based on experience and rough calculations leading to significant differences in the various guidelines used for locating and sizing expansion joints. In response to this complex problem, Expansion Joints in Buildings: Technical Report No. 65 provides federal agencies with practical procedures for evaluating the need for through-building expansion joints in structural framing systems. The report offers guidelines and criteria to standardize the practice of expansion joints in buildings and decrease problems associated with the misuse of expansions joints. Expansions Joints in Buildings: Technical Report No. 65 also makes notable recommendations concerning expansion, isolation, joints, and the manner in which they permit separate segments of the structural frame to expand and to contract in response to temperature fluctuations without adversely affecting the buildings structural integrity or serviceability.

Technical Reports are usually written according to general standards, corporate - sign standards of the current university or company, logical rules and practical - periences. These rules are not known well enough among engineers. There are many books that give general advice in writing. This book is specialised in how to write Technical Reports and addresses not only engineers, but also natural sci- th tists, computer scientists, etc. It is based on the 6 edition published in 2008 by st Vieweg in German and is now published as 1 edition by Springer in English. Both authors of the German edition have long experience in educating en- neers at the University of Applied Sciences Hannover. They have held many l- tures where students had to write reports and took notes about all positive and negative examples that occurred in design reports, lab work reports, and in theses. Prof. Dr. Lutz Hering has worked for VOLKSWAGEN and DAIMLER and then changed to the University of Applied Sciences Hannover where he worked from 1974 until 2000. He held lectures on Technical Drawing, Construction and Design, CAD and Materials Science. Dr. Heike Hering worked nine years as a Technical Writer and was responsible for many CAD manuals in German and English. She is now employed at TÜV NORD Akademie, where she is responsible for E-Learning projects, technical documentation and software training and supervises students who are writing their theses.

The four volumes of Construction Technology provide a comprehensive guide to building technology from simple domestic single storey construction using traditional techniques to more complex multi-storey construction using more modern industrialised techniques. Each volume describes the technology concisely and is well illustrated with the author's own illustrations. The series provides a basic knowledge of all building activities from basic methods of construction in the early volumes through to more complex topics such as site planning, curtain walling and builders plant in later volumes. The series concentrates on the technology and avoids lengthy descriptive passages, leaving the description to the author's very detailed drawings. Volume 2 completes the coverage of conventional methods and materials of construction. As with volume 1, it deals with the construction of a small structure such as a bungalow or two-storey house. The book introduces more complex topics than are covered in volume 1. It deals with site and temporary works, e.g. simple excavations and scaffolding; substructure topics such as retaining walls and reinforce concrete foundations; simple framed buildings; floors and roof structures such as precast concrete floors and asphalt and lead-covered roofs; finishes and fittings such as simple concrete stairs; insulation; and services such as electrical and gas installations.
