I will choose the driveway to explain the engineering specification for a construction project. There are lots of elements that determine the success of this project. Now I would choose the materials, construction methods, the protection of subgrade, the drain and the cold weather protection to explain to a homeowner the engineering specifications and the details required to successfully construct the project.

First of all, material. The materials of the driveway should consist of concrete, water. The driveway for the homeowner should use the one-course Portland cement concrete or a one-course Portland cement combination curb and gutter so as to comply with the line and grades established by the homeowners.

For the concrete, the concrete should include cement, coarse aggregate and the fine aggregate. Since it is a private driveway for the homeowner, there are not so many car would pass the driveway as the normal road. So the stress capability of the surface compressive strength is at least of 2,500 pounds per square.

For the water, the water is required to be clean and free from salt, oil, or organic substances. Therefore, the water from the city rivers. It is better to use water from the house of the homeowners.

Secondly, the construction methods. For the subgrade of the driveways, the subgrade should be formed by excavating to the required depth. When the homeowners encounter the tree roots or big rock under the earth, they should remove the tree roots or rocks to a depth of one foot for the pass of the cars and walkers.

Moreover, if there are soft and spongy places, such places must be removed. For all the depressions filled with suitable material, they should be thoroughly compacted in layers that not exceeding six inches in thickness.

Thirdly, the protection of subgrade. For the protection of subgrade, to protect it from the rain and water, ditches and drains shall be provided and maintained to satisfactorily drain the subgrade. Then pay attention to the environment of the subgrade because the subgrade should not be located on the frost crystals or mud caused by freesing and thawing. Homeowners could choose the suitable materials to remove and replace the frost crystals and mud.

Fourthly, the drain. Just as mentioned above, the drain is necessary for the driveway. Therefore, the homeowner should find the most suitable places to cast a four-inch iron or stell pipe under the driveway. Vitrified clay sewer pipe should be used for drains under the driveway, which should be placed at least three inches below the surface of the concrete.

Fifthly, the cold weather protection. If the project was operated in a cold weather, for example, if the surrounding temperature is below 40 ℉, the homeowner should not continues its project unless there are some heat equipment to protect the project from cold.

That’s a brief suggestion for homeowner to construct a driveway. Above all the specification, we could learn that the success of driveway engineering project should pay attention to the details like the drain, project environment and so on.
