Bills of quantities typically come in three main forms: elemental, trade, and approximate. Elemental bills break down costs by construction elements (e.g., foundations, walls), trade bills categorize costs by specific trades (e.g., plumbing, electrical), and approximate bills provide rough estimates for budgeting purposes without detailed measurements. Each form serves different project needs, aiding in cost estimation and management.
Excavation in road construction refers to the process of removing earth, rock, or other materials from a site to create a foundation for the road. This involves digging trenches or pits to achieve the desired depth and grade, ensuring proper drainage and structural integrity. Excavation is essential for laying down subbase materials and utilities, and it helps prepare the area for subsequent roadway layers. Effective excavation practices also minimize environmental impact and ensure safety during construction.

Retaining walls are built to prevent soil from being lost due to erosion or displacement down a slope. Once built, it can also be used as a beautifying feature in a garden. They usually appear as decorative, and are located on a hill or incline. Retaining walls are used to hold back soil and rocks that might otherwise slide down a hill. Retaining walls can be made of different materials such as rocks and stones.

Western forests were cut down for lumber for railroad and bridge construction
Many railroads had to run up and down steep mountains, around tight curves, and over swift rivers.

it's simple. The rails in the railroad was layed down on a road.
Costs went down while profits went higher. Goods could be transported more cheaply.
right down the middle
Fuel oil costs which are a major expense of generating electric; and the lack of new construction in Florida markets contribute heavily to the analysis. Little new construction stiffles the immediate growth of power use.
Chinese
Yes they are. Its just one big square put together in one straight one. There all connected together to keep costs down on construction. They are also very customizeable.
