The phrase "as-built" in construction is equivalent to "as-is." Drawings deemed "as-built" are thus drawings that show the EXISTING conditions as they are, or "as-is" — these are the actual existing conditions as opposed to designs or proposed conditions, which are more common for the content of drawings. As-built drawings can be documented either after or during construction. When it's after construction, a qualified technician collects accurate data to reconstruct the drawings. When it's during construction, the design drawings are redmarked for editing. For example, if you are a Contractor installing sewer pipe in the road at a buried depth of 5.00' and you suddenly encounter an abandoned pipe and must change your buried depth to 6.50' , then you should be responsible for the as-built conditions. The installing contractor should redmark his set of drawings to show how the sewer line was actually installed so that a draftsman can later edit the drawings into an "as-built" set.
Red Blue asbuilt refers to a method of documenting construction projects, where "Red" indicates the original design or plans, and "Blue" signifies any changes or modifications made during the construction process. This practice ensures that the final construction documents accurately reflect the actual built condition, allowing for easier future maintenance, renovations, or inspections. The contrasting colors help stakeholders quickly identify deviations from the original design.
The cost varies from place to place based on the following components: You would have to hire an excavator. There is A LOT of digging. You would also have to pull permits from the city. You would have to pay for an inspection and possibly an asbuilt and an engineer. The materials are pretty inexpensive, you will mostly be paying for the labor.
