as-built drawing

Not infrequently, the owner or contractor of a building under construction will make field modifications to the original architectural or engineering drawings. Ideally, all such modifications should be noted on one set of plans set aside for that purpose.At the completion of the project, the respective professionals will be asked to generate a new set of drawings showing the actual construction details, rather than original designs, so that future work can be planned and executed in a knowledgeable manner with reference to what already exists in the property. In the alternative, long after a building has been constructed, the owner may employ professionals to prepare plans showing all details of the building and its various systems. Both of these result in as-built drawings.

As regards the two final reports prepared by the Corporation on verification and assurance of the platform slabs and diaphragm walls of the Hung Horn Station Extension as well as the as-constructed conditions of NAT, SAT and HHS, they have been carefully reviewed and the conclusions therein have been accepted by Government and its Expert Advisor Team.
The electric characteristics of the as-constructed NCD-based UV detector were investigated by I-V curve measurement as shown in Figure 6.
The A/E firm should assist in completing the financials, edit and finish the project documentation, provide as-constructed design prints marked by the construction contractor, participate in training, and help develop the final facility and equipment operating procedures.
The Corporation has also submitted to Government (18 July 2019) the report on the holistic assessment study for Hung Hom Station Extension, and the report on the verification study on as-constructed conditions of the North Approach Tunnels (NAT), South Approach Tunnels (SAT) and Hung Hom Stabling Sidings (HHS), all being parts of the SCL project.
When the target values of quality characteristics called for in the specifications are used as inputs, the output produced is the "as-designed life-cycle cost." When the actual measured values of a constructed pavement's quality characteristics are used as inputs, the output produced is the estimated "as-constructed life-cycle cost." The difference between the as-designed and as-constructed life-cycle cost is the basis for any pay adjustment, either positive or negative.
The first purpose is to verify the as-constructed details through opening up the concrete for physical investigation at locations where the MTRCL has found gaps in the documentation about the steel reinforcement.
* Engineers have long believed that the long-term performance of a pavement is related to the initial, as-constructed smoothness.
The first purpose of opening up the concrete is to carry out physical investigations at locations with gaps in the documentation, so as to verify the as-constructed conditions of the connections between the platform slabs and diaphragm walls.
The goal is to develop a system for identifying and specifying the construction of a target or "as-designed" pavement and then to equitably reward or penalize the contractor for the quality of the "as-constructed" pavement.
To verify the as-constructed condition of the structures including the platform slabs of the Hung Hom Station Extension, the Government has requested the MTRCL to formulate a holistic strategy.
He concluded by showing Topcon drones capturing imagery of the completed highway, bringing that data via Topcons MAGNET Enterprise through ContextCapture Cloud Processing Serviceto create an as-constructed reality mesh for use in the new AssetWise road network management, maintenance, and inspection workflows.
