Inside the circle, there is a reference number or letter referring to the elevation drawing number or letter, and underneath this, is the drawing sheet number where that elevation can be found. I challenged myself to locate everything that needed to be located with as few dimensions as possible. Just be consistent. Set the dimension with respect to the grid line. The face sheet will often contain a drawing contents table (similar to a book; a list of drawing titles and their corresponding drawing number). A: The 0'- is annoying and unnecessary, and it takes up valuable space in a dimension string. So, Number the column to the basis of its size & reinforcement. It might be to show the different hatches used to represent materials and what they mean. For construction tolerances, convert inches to millimeters and round to the nearest 0 or 5mm (so 1/4" is 5mm). I have also seen industrial plants laid out in a coordinate system. Column Layout Work This is the first step of column construction. Here are common RCP symbols: MT Copeland offers video-based online classes that give you a foundation in construction fundamentals with real-world applications. He learned to build and weld while working on the farm with his grandad, and after earning a degree in Welding and Materials Engineering, he spent the next 10 years working in the heavy construction building everything from robots to ships to offshore oil rigs before transitioning to residential construction. Now we can see the section view of this slice, we can also see our large hole/void within the slab which was indicated on the GA plan. If you experience an issue, please check back later. Draw the grid line (horizontal & vertical) by using line (l+Enter) or construction line (xl+Enter) command. Quality Assurance Information of the Drawings: Contains the QA and administrative information for the drawing including the initials of the people who drew it and checked it. Blueprints are typically drawn on a -inch scale, which means every quarter-inch on the plan equals 1 foot of actual length on the completed structure. I cant provide the desire, but I can offer the following tips. Or get a copy of the floor plan and add your own matrix grid over the plan - and attach your grid plan to each of your reports as a reference for location descriptions. In those cases, make sure you dimension to the face of partition finishes; otherwise, the clear dimension could be as much as an inch less than intended (and the room wont meet the required clear width). Every aspect of construction is governed by tolerances and degrees of precision. There is no reasonable limit to the number of "fractional" column lines - in addition to the "3.4" (in this example) could also have, say "3.1", "3.6", 3.9", etc. Draw the column. Although there are standards, may practices adapt the standard numbering system to reflect the needs of their own office. Each line will provide a coordinate (such as 'the wall located along grid line A'), which can act as a datum or reference point for a builder to measure off. The north arrow tells you about the orientation of the property. Learn how your comment data is processed. A key can be used in a number of ways. A heavy line will represent cutting planes and contours of an object, like a wall for example. Q: So who cares about all this. Understand the architectural sheets. Building drawings are read similar to a book, and just like a book the drawings need a cover page. Close this window and log in. . Overly large rounding can hide fractional dimensions that may be appropriate, or allow a string of hidden fractional dimensions accumulate into a significant dimensional error. https://sheerforceeng.com/what-is-top-down-constuction/ I've never had any problem with column lines being at some location other than the centerline of columns. They can be referred to by dimensions from column grids or as SlideRuleEra has noted. Even a plan that follows all the above tips can still look ugly and messy.

Its placed there for reference so that anyone looking at the floor plan can understand how the rooms were intended to be set up. You can read the description as circled in red as the electrical panel number and the circuit in that panel, such as; P5-16 (Panel 5, Circuit 16).This indicates that VAV 1-5 has electrical conduit and wire coming from panel 5 and circuit #16 in that panel. [4] All these industry standards and more can be found in the Handbook of Construction Tolerances by David Ballast. Finally the drawing number and revision is also provided. Most important dimensions, the ones that really matter, are nice round numbers, usually to the nearest inch. only the structural slab thickness is shown (in this case 250mm thick or 9.84inch thick for those playing at home in the US). Open dimension strings are usually preferred, and the reason is tied to construction tolerances. Usually columns are laid out in a grid and one axis is lettered and the other is numbered thus column B5 is at the intersection of lines 'B' and '5'. In my drafting days, I used to approach dimensioning as a sort of puzzle. Dimensioning provides accurate sizing on objects in the drawing.
