But make no mistake: This isn’t charity—the houses are not given away. Rather» in addition to shouldering a modest mortgage, the new homeowners put in around 500 hours of “sweat equity,” working with volunteers who help them build their house. In the few years I have lived here in Coos Bay, Oregon, we have built eight houses that have become homes for the families who worked with us. Because of all the volunteer labor, we are able to build these houses for about $30,000 to $35,000, plus land, which results in a mortgage that even low-income families can handle.

lfHFH can build an affordable house, why can’t anyone? First of all, others arc doing it. More than 175,000 owner-builders create new housing units each year. It takes a significant amount of courage, effort, and time, not to mention a piece of land, some money, and help from friends—but it can and is being done. How to build a simple house is not a mystery. It’s rather like putting together Lego blocks or Lincoln Logs, one piece at a time. Many of vou already have the basic skills needed to build a simple house. Just look at the thousands of people who flood places like Home Depot and Lowe’s to buy tools and materials for working around their homes.

If you’re considering building your own home, keep in mind that it is also possible to build a home that is beautiful but, in the long

run, is neither decent nor affordable. Decent housing, for example, coesn’t have leaks that can cause mold and rot, compromising both vonr health and your home. Neither is decent housing full of toxic fumes, which can come from paint, carpet, and a host of other com­mon, seemingly innocuous, materials. A decent, affordable home is energy efficient, well ventilated, and comfortable; built from safe, health-preserving materials; and requires a minimum of upkeep or maintenance. It can also be built from forest products and other materials that are sustainable, so that we don’t further lay waste to our homeland. Building such a home isn’t impossible, but it does take some careful planning.

So, where do you start? There is an old saving, "You can hear a ot just by listening.

Read the how-to information that comes with many building materials; study this book and others; check out the numerous how-to-build sites on the Web (see Resources on p. 278). Ask questions, work out details and ideas on paper, and gradually the big picture will start to get clearer. Although no single book can answer all the questions you’re likely to have on the subject, it’s my intent to provide a step oy-step guide that will take you from basic planning and design through the actual construction of a simple, decent, affordable house.

BUILDING A HOUSE IS A LONG JOURNEY, and one of the most important characteristics you can possess is optimism. In this context, 1 often think about president Jimmy Carter, who has done so much to promote the work of Habitat for Humanity. Over the years, he has helped build hundreds of houses in the sincere belief that decent housing can be made available to every human being. As you take your first steps toward building a house, remember Mr. Carters optimistic altitude, and make it your own.

A HOUSE

Since this book was first published in 2002, the need for decent, affordable housing in this country (and throughout the world) has only in­creased. It is astonishing, but millions of families spend over one-third of their income on housing alone. Even families with steady middle-class incomes struggle to purchase homes and make mortgage payments on time. Money that used to go toward medical care, food, and a child’s education is now spent so families can keep a roof over their heads.

I was born and raised in a wood-frame house sited high on the short-grass prairies of western Nebraska, that huge inland sea of grass where the only constant is the wind whistling across the snow-covered, sagebrush hills. Aged, warped, unpainted clapboard siding hardly slowed the wind and cold. It was an uninsulated farmhouse with no central heating, no electricity, no indoor plumbing, and windows that let in more wind than light. Just 3 ft. from the iron stove in the kitchen, it was freezing. In our bedrooms, even when Mother warmed the sheets with her flat iron, the temperature never got much above what it was outside.

The pace was slow and methodical. A wall chalkline would be snapped on the floor. The bottom plate was nailed to the line. Corner posts were then set and a string pulled taut over posts from corner to corner. The length of each wall stud was measured from that string.

Theory and Practice

Many years have passed since the beginning of stone matrix asphalt’s (SMA’s) world­wide success. Therefore now the right moment has come to review all accessible information.

Through this new book I have tried to assemble, in an organized manner, a cer­tain body of knowledge obtained from a vast number of publications the world over, thus providing a review of the achievements of numerous engineers from various countries working on bringing recognition to SMA and developing its design meth­ods. I did my best to explain that knowledge and to present it in an accessible way. Some useful hints resulting from my experiences encountered during the introduc­tion of SMA in the early 1990s, discussions with many process engineers, and later reflections and observations round out the theoretical deliberations.

Knowledge of SMA is steadily improving, and new test results are revealed every now and then. In light of this, the moment when we can say that we really “know everything” about it is still far away. Alas, there is not one foolproof method for obtaining a perfect SMA in this book. Moreover, I tend to think such a recipe does not exist at all. This is not necessarily a bad thing because there is nothing like the ability to think and imagine when designing a mixture. The information put into the text is intended to help with using SMA. The range of accessible literature is really broad, so its accumulation and explanation are almost like putting together a jigsaw puzzle. Only the combination of many pieces of information enables associating certain relationships or finding out cause-and-effect relations. It is the reader’s task to judge whether that jigsaw puzzle has been appropriately completed.

Undoubtedly, the diversified terminology and the methods of testing properties of constituent materials and mixtures were quite a challenge when compiling this book.

Summing up this foreword, I feel that it should be emphasized again that the knowledge of this technology constitutes the considerable sum of experiences of many people. Therefore there is no particular individual who knows “everything” about SMA. In other words, no matter how much you already know about SMA, it is always worth broadening your knowledge!

Preface

Background

This book is the most obvious outcome of the “COST 351, WATMOVE” project (see www. watmove. org). For most readers these terms probably mean little so some explanation is called for. In 2001/2002 a small group led by Kent Gustafson of the Swedish Road and Traffic Institute (VTI) made a proposal to the European programme on “Co-operation in Science and Technology” (COST). They proposed that a pan-European team be set up to study the issue of “Water Movements in Road Pavements and Embankments” (acronym = WATMOVE). The COST organisation agreed the proposal and the study formally began in December 2003 with the sup­port of COST. Due to ill-health, Kent was not able to lead the project and I was asked by the Management Committee to chair the project team.

Scope of the Book

This book is NOT about “Water and Roads”, nor on “Water on Roads”. There are other books which deal with surface water drainage in great detail and there are other source materials that deal with the impact of roads on water in the general environment. To cover every aspect of the interaction between water and highways would have required a much greater effort and a much thicker book. So this book seeks to limit itself to:

(i) Water inside the road construction and the underlying subgrade soils and rocks;

(ii) Water from the surface down to the phreatic surface,[1] and

(iii) Water in the road and ground between the fence-lines of the highway.

Sometimes these boundaries to the book’s scope were a little bit too limiting so, from time-to-time the book wanders somewhat further. For example, it proved impossible (and undesirable) to discuss water in the road construction without
mentioning from where it comes. So, there is some consideration of run-off in so far as it is the major contributor to sub-surface road water, but readers will not find a full description of surface water drainage systems. Within these self-set limits the authors have tried to address most conceivable topics in some detail, bringing together both established theory and practice and some of the latest developments.

Timer Framing for the Rest of Us

r

imber Framing for the Rest of Us. Us implies Them, or They or Not Us. And who are these others? They are no less than the skilled timber-framers, using time-tested methods of creating beautiful, strong, and enduring buildings throughout the world. At its best, timber framing done by traditional methods of joinery yields a quality of construction that spans the range from craft to art.

The use of timber-framing joinery, such as scarf, mortise-and-tenon, and rabbet joints, evolved during a time before metal fasteners were available, and its traditional use continued when metal spikes would have been expensive. Quality wood-on-wood timber framing continues to this day, and is a joy to see. There are plenty of good books to show how the work is done, and building schools that will teach the owner-builder these skills. Books are listed in the Bibliography, and schools and other resources are listed in Appendix C.

I have the highest admiration for these traditional builders. A good friend, who died much too young, took great pride in restoring historic timber frame buildings in Northern New York, often working to 1/64-inch (0.39 millimeter) tolerance. But the reality is that most timber framing is not done in the old-fashioned “traditional” way with wooden pegs, mortise-and-tenon joints, and the like. With the advent of relatively inexpensive mechanical fasteners, most builders — contractors and owner-builders alike — rely on other methods of joining, using things such as truss plates, screws and bolts, pole-barn nails, and even gravity. The problem is that there is a shortage of information about joining heavy timbers by these methods. Most construction manuals are quite good about describing the joining of “two-by” lumber — usually 1V2 inches (3.81 centimeters) thick nowadays — and that’s the extent of it. Chapter 1 speaks about traditional timber framing… and the kind that this book is about.

However, many of the natural building methods which are becoming re­popularized today — such as cordwood masonry, straw bale construction, and cob building — benefit from heavy timber construction, primarily because these

methods involve thick walls. There is also a great practical advantage in erecting a timber frame first, getting the roof on as a protective umbrella, and then infilling the structure using one or more of these natural — and typically slow — building methods. Before starting, though, its good to have an understanding of the basic structural elements of timber framing, which is what Chapter 2 is all about. You’ll also need the timbers themselves. Where to get them is the subject of Chapter 3.

Yes, you can accomplish all this with “traditional” wood-on-wood joining methods. I have even met two or three who have done so and my hat is off to them. But to do it right, a great deal of time and study must be expended, and there are a few specialized tools which need to be purchased. The reality is that most farmers, contractors, and owner-builders use methods of heavy timber framing which they have simply picked up from colleagues, relatives, or neighbors. And they use common tools found around the homestead, such as chainsaws, hammers, and electric drills. For years, I have felt that there has been a void in the literature for owner-builders on this subject, and that is why I have undertaken this volume as a kind of “missing link.” Chapter 4 explains the basics of timber framing for the rest of us.

My qualifications are unpretentious. I’ve written about alternative building methods for almost thirty years and, with my wife Jaki, I’ve built four houses, a garage, and quite a few smaller outbuildings using the methods described herein. In fact, Jaki and I built a new addition to our Earthwood house in 2002, and the primary reason for it was to demonstrate and document some simple joining principles for this book. Chapter 5 takes you through this entire project from design to completion, step by logical step.

This book is not meant to document all of the methods and fasteners that are available. Rather, it demonstrates and describes the basic principles of building with heavy timbers by “non-traditional” methods (even though these non- traditional methods are certainly more common nowadays than the traditional ones.) It will show how to build very strong structures with a minimum of wood­joining skills.

Finally, to the expert timber framing craftsmen and teachers like Steve Chappell, Will Beemer, Jack Sobon, Tedd Benson, and so many others, I say that is not my intention to diminish your fine work in any way. Rather, I hope it will enhance appreciation of the craftsmanship that you practice and teach so generously, and, at the same time, offer a viable alternative. Those with time and

inclination may want to incorporate some traditional joints in their project, especially where they can be left exposed. I have done this once or twice and was rather proud of myself afterwards.

Venture for Affordable Housing

Подпись:

The Joint Venture for Affordable Housing (JVAH) program has been a significant

step toward lowering housing costs. This manual contains a compilation of proven cost-saving construction techniques. All the techniques may not be applicable in every situation, but most builders will likely find many ways to lower housing costs. Volume I, the companion manual, contains proven cost-reduction methods of land planning and development as well as actions local governments can take to encourage more affordable housing.

Acknowledgements

This manual is the result of material obtained from the Joint Venture for Affordable Housing Demonstration builders and from other sources. It was prepared for the Department of Housing and Urban Development by the NAHB National. Research Center. The demonstration, program was directed by the Office of Policy Development and Research.

The principal author was E. Lee Fisher, with assistance from Carol B. Schaake, Richard A. Morris, and untold others who provided years of residential research effort and documentation. Most importantly, we wish to thank the builders of the JVAH
demonstration and the communities who took the risks and put their resources on the line to prove that affordable housing for all Americans can be a reality.

The work that provided the basis of this publication was supported by funding under a contract with the U. S. Department of Housing and Urban Development. The substance and findings of that work are dedicated to the public. The authors are solely responsible for the accuracy of the statements and interpretations contained in this publication. Such interpretations do not necessarily reflect the views of the Government.

HUD’s Joint Venture for Affordable Housing (JVAH) demonstration was a – program designed to help reevaluate building regulations and typical builder practices in an attempt to find solutions for building afford­able homes. Many cost saving construction methods had been developed over the years but had not been adopted by local codes or had not been put into practice by builders. The U. S. Department of Housing and Urban Development (HUD), the National Association of Home Builders (NAHB), and the NAHB National Research Center (NAHB/NRC), compiled those ideas and, working with builders, developers and community officials all over the nation, instituted many of them with outstanding results.

The JVAH demonstration program was extremely successful in encouraging understanding and cooperation between different interest groups in finding solutions to high housing costs.

This was accomplished by restructur­ing processing procedures, using land more efficiently, revising outmoded land development practices, and using proven cost-saving construction techniques.

This guide contains methods to reduce costs in most phases of direct construction of the house itself.

Cost-saving land use and development techniques and streamlined processing procedures are presented in a companion manual (See Volume I).

Most of the methods described herein were demonstrated in at least one of the JVAH sites. Many were repeated in almost all of the sites. The guide is not intended to be the definitive construction manual, but rather a compilation of techniques that were proven effective in the JVAH program and in other areas.

Most homes in the demonstration program were "stick-built" on site.

Some were factory-built, i. e., modular, HUD Code, orpanelized.

The manual is written for those who are already familiar with construc­tion terminology and "typical" ways of building homes. A reference section at the end of the manual contains titles and sources of other manuals that will provide more complete backup information and data.

It is likely that some of the methods discussed herein are not presently acceptable under some local regulations. Before attempting to adopt any new technique, check the local code or with local building officials. If not acceptable, it will be worthwhile to work with the local authorities for change.

Success of an affordable housing program depends upon builders, government officials, and concerned citizens taking necessary steps to encourage innovation.

The manual is organized along the lines of how a house is built starting with design, then footings and foundations, floors, walls, etc. Each section contains a general discussion of the topic followed by specific cost-saving innovations, and then JVAH case study experiences. Hopefully each reader will find several ideas that will result in reducing housing costs without sacrificing health, safety, and general welfare features.
