Plumbers, electricians, joiners, plasterers and other trades still have paperwork to do, but builders tend to have considerably more paperwork because they are usually the main contractor, involved from the start to the finish of a project. Running your own business is something that many builders aspire to. It's almost like a rite of passage - being an apprentice, qualifying and then going out on your own. New Zealand is full of small enterprises, and the construction industry has more than average.

So how does a builder know what to do when they make the decision to go it alone? They learn from others (and the mistakes of others), they do some things that work well and others that don't, but until now there has been no one place they can go to find out everything they need to consider before starting their own business.

This book outlines the key things a builder starting their own business needs to think about - many of which are legal requirements. For those already running a business, it is a chance to evaluate progress and get some ideas on improvements.

The aim of this guide is to provide easy-to-follow practical design and construction information for designers, builders and building consent authorities who are unfamiliar with lightweight steel framing, which has a growing market share in housing construction. 

This guide covers: 

• statutory requirements
• steel framing materials
• thermal breaks
• the fabrication process
• design and erection
• roof and wall underlays
• windows and external doors
• wall claddings
• roof claddings
• insulation
• wiring and piping installation
• internal fit-out.

Construction and demolition waste is mainly solid waste and typically includes packaging from new building materials as well as wood, plasterboard, metal, concrete and rubble resulting from construction, renovation and demolition of buildings. Plant matter and unwanted soil shifted during the building process also fall into the waste category. 

The key steps to follow in design and construction are to reduce, reuse, recycle and recover. This book is aimed at builders, designers, tradespeople and educators and explains with detailed guidance and case studies how these steps can be achieved.

This seminar will travel along the path of timber as it is prepared for a career in the building industry. Starting off in the forest, we will explore the influences on the timber as it grows and how this will impact on its properties as sawn timber. Once felled, the timber starts its processing journey where it is again subject to many influences.

Once in its sawn forms, framing and wall cladding, we will then traverse the treatment options for the end use, drying, storage (during transport and on site), installation and post-installation care. For timber weatherboard claddings, we will cover the requirements for a good installation including storage and transport, defects, suitable species, treatment, applicable codes and standards, installation and fixing, as well as appropriate coatings for the treatment and finally maintenance.

Specifying and fixing internal linings demands a high degree of skill to ensure that the finished installation will perform in the environment the internal linings are installed in and meet the end user's expectations. There is a wide range of internal lining materials available, and there is often a gap between what is expected of particular lining materials and what is achievable given the construction methods being used. 

This guide covers most current wall and ceiling lining applications including lining selection, support systems and fixings. It sets out the requirements and installation processes for all aspects of lining installtion so that realistic finish quality levels can be set and the completed installation achieves the expected quality level. It does not cover the selection and installation of suspended ceiling systems. 

The audience is designers and specifiers, builders, partition installers, lining installers, stopping contractors, building officials, building owners and students of design and construction.

This publication helps designers, specifiers and builders ensure that new and existing houses are warm and effectively ventilated, providing owner comfort, convenience, health and safety while minimising running costs. It acknowledges the importance of good passive design - taking advantage of free sources of energy such as sun and wind to provide heating, cooling and ventilation.

This publication covers:

• heating and cooling design considerations and methods
• thermal design
• ventilation design considerations and methods.

Windows and glazed doors play a vital role in sustainable building. They can account for more heat gain or loss than any other element in an insulated building envelope. A well designed glazing system can improve internal daylight levels, reduce glare and help maintain thermal comfort by reducing heat gain and loss. This contributes to energy efficiency by reducing the need for artificial heating, cooling or lighting.

This guide covers: 

• building controls
• functions of windows
• performance of windows
• aluminium, uPVC, steel, timber and fibreglass windows
• classification of opening windows
• glazing
• insulating glass units (IGUs)
• fittings and accessories
• building construction.

This guide does not cover overhead glazing, roof windows, skylights or commercial facades or window sections.

The thermal performance requirements of building elements given in this book are from the 4th edition Building Code acceptable solution H1/AS1 and verification method H1/VM1. Note that 5th editions of H1/AS1 and H1/VM1 replaced the 4th edition from 3 November 2022.

This guide covers important choices facing designers and homeowners in selecting active energy systems such as water heating, space heating and lighting and looks at options such as photovoltaic electricity generation. Considerations include what different technologies can achieve and which options are more energy efficient and environmentally friendly than others.

It explains the requirements of the New Zealand Building Code, standards and other obligations that need to be met while pointing out that going better than the required minimum typically brings benefits in comfort and ongoing cost savings.

Note that the energy efficiency requirements in the Building Code have been amended since the publication of this book.

Approximately 10% of New Zealand households rely on rainwater collected from roofs for their water supply. Typically, these are rural residential properties but may include country schools, camping grounds, marae and other community buildings. A number of fairly simple and relatively inexpensive measures can be introduced to existing systems to improve water quality

This Good Repair Guide looks at upgrading options and maintenance requirements for existing rainwater storage systems to ensure a quality potable roof water collection and storage system is maintained. 

Clay and concrete tiles have long been popular choices of roofing material, particularly in severe coastal or thermal environments. As a general rule, clay and concrete tile roofs can be expected to last 50 or 60 years before needing replacement.

Regular checks and proper maintenance are critical to keep the roof in sound condition and to keep the water out. This Good Repair Guide focuses on the repair options for isolated areas of concern. 

Hinges for timber doors and windows are frequently overlooked hardware items. It is not until they fail to operate properly that attention is paid to them. By the time this occurs, they are sometimes beyond refurbishment, and replacement is the only option. If problems are addressed before they become too serious, hinges can generally be refurbished and restored.

This Good Repair Guide looks at the types of hinges used with timber doors and windows, the problems that can occur and how they can be refurbished and, if necessary, replaced.

Although the many atttibutes of concrete such as compressive strength, excellent durability and versatility are well known, concrete floors are not completely immune from problems. This Good Repair Guide focuses on the restoration of the appearance of concrete floors.

Inconsistency of the original concrete mix, poor surface finishing and inadequate curing may result in a floor finish that is less than acceptable. Shrinkage cracking, staining, surface pitting and wear from vehicle or foot traffic can also be a problem.

Overlay flooring is a flooring system that is laid over timber tongue and groove (T&G) boards, particleboard, plywood or concrete. It includes solid timber boards, parquet flooring, timber composite flooring systems and bamboo flooring

This Good Repair Guide describes the repair options for existing overlay flooring. It describes how to: 

• repair minor damage
• replace a section of floor
• replace an entire floor
• prepare an overlay floor for a new protective finish.  

Floor coverings such as cork tiles, vinyl tiles or sheet vinyl are not covered by this guide.
