International Residential Code
This comprehensive code comprises all building, plumbing, mechanical, fuel gas and electrical requirements for one- and two-family dwellings and townhouses up to three stories. The IRC contains many important changes such as: An updated seismic map reflects the most conservative Seismic Design Category (SDC) based on any soil type and a new map reflects less conservative SDCs when Site Class A, B or D is applicable. The townhouse separation provisions now include options for using two separate fire-resistant-rated walls or a common wall. An emergency escape and rescue opening is no longer required in basement sleeping rooms where the dwelling has an automatic fire sprinkler system and the basement has a second means of egress or an emergency escape opening. The exemption for interconnection of smoke alarms in existing areas has been deleted. New girder/header tables have been revised to incorporate the use of #2 Southern Pine in lieu of #1 Southern Pine. New tables address alternative wood stud heights and the required number of full height studs in high wind areas.

Nascla Contractors Guide to Business Law and Project Management
The NASCLA Contractors Guide to Business, Law and Project Management is organized into 3 sections.
Part 1 focuses on business planning and start up. This section will help you formulate a business plan, choose a business structure, understand licensing and insurance requirements and gain basic management and marketing skills.
Part 2 is centered on fundamentals that you will need to operate a successful construction business. This section will cover estimating, contract management, scheduling, project management, safety and environmental responsibilities and building good relationships with employees, subcontractors and customers.
Part 3 gives you valuable information for running the administrative functions of your business. Financial management, tax basics and lien laws are covered. Effective management of these areas of business is vital and can cause you serious problems if you do not give them the proper attention.
Manual D Residential Duct Systems
The ANSI-recognized national standard for residential HVAC duct design will help you design a duct system in less time. The popular and accurate procedure has been revised to include updated and expanded VAV guidance, with detailed examples; impacts of excess length, sag and compression in flexible ducts; and new equivalent length values for flex duct junction boxes. Manual D, from the Air Conditioning Contractors of America (ACCA), provides a single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials.
The newly released Manual D has been significantly revised to include:
-Updated and expanded VAV guidance, with detailed examples.
-Impacts of excess length, sag and compression in flexible ducts.
-New equivalent length values for flex duct junction boxes.
Manual D provides:
-A single set of ANSI-recognized duct sizing principles and calculations that apply to all duct materials
-System operating point (supply Cfm and external static pressure), and airway sizing for single-speed and multi-speed (ECM) blowers
-A method for determining the impact of duct friction and fitting pressure drop on blower performance and air delivery
-The most comprehensive equivalent length data ever published.
You can apply the Manual D procedure to constant volume systems and zoned variable air volume systems, over a full range of duct construction materials. Manual D includes a number of informative appendices related to air distribution systems (e.g., equipment and air-side components, controlling excess air when VAV dampers close, duct loads, duct leakage and duct system efficiency, air quality issues, noise control, minimum air velocity for ducts; codes, standards and best practice issues; and commissioning issues).
Manual J Residential Load Calculations 8th addition Abridged
Manual J 8th Edition is the national ANSIrecognized standard for producing HVAC equipment sizing loads for singlefamily detached homes, small multiunit structures, condominiums, town houses, and manufactured homes. A proper load calculation, performed in accordance with the Manual J 8th Edition procedure, is required by national building codes and most state and local jurisdictions.
Trane or ACCA Ductulator
The Ductulator – Duct Sizing Calculator is a hand held rotating calculator used for sizing supply and return duct systems using the equal friction design method. Includes scales for friction loss per unit length, air volume, air velocity, round duct diameter, and rectangular duct diameters. One side uses English units, the other side uses Metric units. Includes a protective sleeve with ASHRAE recommended design air velocities for system components/applications.
