Massachusetts-Building Construction Unrestricted Contractor Online Practice Test

These are actual questions from our online practice test.

We have included a question from each chapter of the test. Every question will be multiple choice. The answers are not included with the sample.

Sample Questions

# Chapter Title Question
1 Rough Carpentry and Framing There should be no more than how many feet vertically between landings?
2 Insulation and Vapor Barriers Technically, any air-based insulation material cannot exceed an R-value of R-5.5/in. because _____________.
3 Finish Carpentry, Firewalls, Cabinets, Doors and Windows What is is the best type of self drilling screw?
4 Finish Carpentry, Moldings, Closets and Hardware The diameter of grab bars are required to be no less than 1 1/4 inches, and no more than ______ inches.
5 Finish Carpentry, Wood Flooring, Installing, Parquet Flooring and Types of Cuts Subfloor sheathing is typically manufactured in _______ sheets.
6 Finish Carpentry, Wood Flooring, Installing, Staining, Sanding, Sealers and Thermal Moisture Protection ________________ are high performance building panels used in floors, walls, and roofs for residential and light commercial buildings. The panels are made by sandwiching a core of rigid foam plastic insulation between two structural skins of oriented strand board (OSB), or plywood. Plywood thickness may increase with larger buildings.
7 Siding When joining siding horizontally to stucco, what flashing should be used?
8 Thermal Moisture Protection

When estimating wood siding take-off, allowance for ________ should be included.

9 Drywall, Installation, Joint Compounds, Plaster Joints, Taping, Coating and Seams Knock down roller finishes are achieved the same way hand applied textures, except _______ with a large flat curved blade trowel?
10 Drywall, Metal Studs and Metal Framing

Studs form walls and may carry ______________ structural loads or be non load-bearing such as in partition walls which only separate spaces. They hold in place the windows, doors, interior finish, exterior sheathing or siding, insulation and utilities and help give shape to a building. Studs run from sill plate to wall plate. In modern construction studs are fastened to the plates in a way, such as using ties, to prevent the building from being lifted off the foundation by severe wind or earthquake.


11 Concrete, Mixtures, Strength, Pressure, Forms and Foundations A _______________ is used to transfer the load of a structure down through the upper weak layer of topsoil to the stronger layer of subsoil below.
12 Concrete, Shotcrete and Concrete Formwork Forms should not be removed until the concrete has achieved _______% of it’s strength.
13 Concrete, Reinforcing Steel, Structural, Rebar and Ties What should forms be made of?
14 Steel Joists and Joist Girders


15 Steel Framing, Steel Columns and Steel Erection

Bracing connections are generally made with _______________ bolts in clearance holes. In theory at least, this allows some movement in the connection, but in practice this is ignored in orthodox construction. In some cases it may be that movement on reversal is unacceptable - preloaded connections should be used in these circumstances.

The general design process is:

  • Identify the load path through the connection
  • Arrange the connection to ensure that the design intent of the members is realised, e.g. the beam connections remain nominally pinned
  • Include the effects of any significant eccentricity
  • Check the components in the connection.
16 Masonry Mortar Mixtures, Prisms and Chimneys

_______________________ draft is when air or flue gases flow under the effect of a gradually decreasing pressure below atmospheric pressure. In this case, the system is said to operate under induced draft. The stacks (or chimneys) provide sufficient natural draft to meet the low draft loss needs. In order to meet higher pressure differentials, the stacks must simultaneously operate with draft fans.



17 Masonry, Reinforcing Steel Bars, Walls, Mortar and Concrete ________ bar support is used to prevent rebar from moving when being grouted.
18 Excavating, Grading, Compaction, Soils, Cleaning Worksite and Drainage

The term dry dam refers to a dam that serves purely for flood control without any conservation storage.

19 Sewer System, Location Sites, Soil Conditions and Septic Tanks Prior to clearing critical grading jobs, it may be necessary to have a _____________ sample and inspect the material and construction site soils.
20 Sewer Installation, Pipe Lines, Leach Fields and Septic Tanks Sewer line connections to existing lines or manholes are not made until upstream lines have been _____________.
21 Roofing Tile, Slate, Mathemathics, Calculations and Formulas When laying tile if there is an uneven surface, how is that repaired?
22 Roofing, Aluminum, Roofing Panels, Gulvalume, Galfan, Hips, Valleys and Seams How many times its weight in asphalt must felt be able to absorb?
23 Roofing, Composition Shingles, Metal Roofing, Drainage Slope and Asphalt Roofs are sloped a minimum of how many ___ inches in 12" for drainage?
24 Roofing, Eaves, Gables, Asphalt Shingles, Rafters and Membrane A ______________ is any longitudinal, horizontal, structural member in a roof except a type of framing with what is called a crown plate.
25 Mechanical, Boilers and Furnaces Mechanical plans and specifications are usually required for buildings having an area of _________ sq. ft. or more.
26 Safety, Dig Alert and Fire Extinguishers

If an emergency notice must be given to ,Dig Safe System, Inc, the utility companies, will attempt to respond within _______.

27 Employees, Contractors, Insurance, Safety and Training When should an employer provide information on safety procedures?
28 OSHA Standards, Asbestos, Code of Federal Regulations, Title 29, Part 1926, Basic Estimating and Blueprint Reading A revision (marker) is shown on the completed set of working drawings by _______________.
29 Mathematics and Calculations An executive invests $10,000,some at 9% and some at 8% annual interest. If he receives an annual return of $830, how much is invested at each rate?
