A drawing the intended locations of plant items and service routes in such detail as to indicate the design intent. The main features of detailed design drawings should be as follows: Plan layouts to a scale of at least 1:100. Plant areas to a scale of at least 1:50 and accompanied by cross-sections.
Example mechanical drawing. Here is an example of an engineering drawing (an isometric view of the same object is shown above). The different line types are colored for clarity. Black = object line and hatching; Red = hidden line; Blue = center line of piece or opening; Magenta = phantom line or cutting plane line
The systems, equipment, items, processes, modes, and sequences of operations to be tested by the CxP (contractors or others) should be detailed and identified in the design engineer's construction documents (drawings and specifications), the construction request for proposal (RFP), the contractors' bid submission, the commissioning ...
For example, surveyors used to use two posts joined with a chain to measure distance. This technology could only account for distance and not elevation. Current technology uses Global Navigation Satellite Systems (GNSS) that can measure the distance from point A to point B as well as differences in elevation.
A practical example is as follows. An aircraft maker contracts with a vendor to make parts. A certain grade of steel is specified for the part because it is strong enough and hard enough for the part's function. The steel is machinable although not free-machining. The vendor decides to mill the parts.
The meridian is the plane that contains both the axis of the Earth's rotation and the observer. The intersection of the meridian plane with the horizontal defines the true north-south direction found in this way. Unlike magnetic compasses, gyrocompasses are able to find true north, the surface direction toward the north pole.
Rolls-Royce CEO Chris Brownridge, like many other importers, is wary of President-elect Donald Trump's plans to impose an array of tariffs on an array of countries.But he's not all that worried ...
For example, Caterpillar's smallest mini-excavator weighs 2,060 pounds (930 kg) and has 13 hp; [8] their largest model is the largest excavator available (developed and produced by the Orenstein & Koppel, Germany, until the takeover 2011 by Caterpillar, named »RH400«), the CAT 6090, which weighs in excess of 2,160,510 pounds (979,990 kg), has ...
