[2] While these tips may sound like dogmatic rules, none are unbreakable. Lets say were dimensioning between two concrete columns. Dotted and dashed lines can indicate hidden items, or ceiling height changes, wheelchair turning circles and so on. Lets take a look to see how a concrete framed floor may look on a structural general arrangement plan (often called a GA plan), lets not overwhelm ourselves and just look at a small portion of a larger floor plan, Ok theres a lot going on here! A column's minimum width is 200 mm, however for earthquake resistance, it should be 300 mm. "we as structural engineers do not reinforce as strongly as we need to". Examine the drawing for lines and arrows which indicate the direction of the structure. Q: For dimensions less than one foot, Revit always inserts a 0'- (e.g., 0'-6") in front the inches. 2009-2021 The Constructor. Just the number of software programs that interns need to master is daunting: Revit, AutoCAD, Word, Excel, 3D Studio Max, PowerPoint, Photoshop, InDesign, Grasshopper, Rhino, Ladybug, Octopus, DungBeetle, and goodness knows what else [1]. 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). https://sheerforceeng.com/why-did-the-fiu-bridge-collapse/ The MEP drawings will show the location of physical fixtures and the routing of the lines. It takes its name from the idea that you are looking down at the ceiling as though there were a mirror on the floor reflecting the ceilings plan back to you. Lines can be continuous (ie solid) or dashed. First we will go through the general drawing elements which are usually common across the disciplines. In industrial plants, I run into columns that are off column grids all the time. At the bottom of the drawings is the location of the lift/stair shaft including the bathroom facilities. On building plans, gridline heads should be shown at both ends of. The reference grids are read similar to the old fashioned game of battle ship; a row of grids following sequential numbers (for example running horizontally) and a row of grids following sequential letters (for example running vertically). https://sheerforceeng.com/what-is-top-down-constuction/ Identify the overall purpose of the drawing. Drawing List could include the following Trade Drawings; The main purpose of the title block is to identify the project and engineers involved in the design. These invisible portions of an item are often represented by dashed lines. A column line is simply a line with a bubble on it that is used as a reference. This is the view that shows the outside or inside of the building from a standing position, eyes forward. The following are the most common line types you will encounter. All the drawings together will provide for a fully constructed project, covering everything from the structure to the mechanical systems. Yes? The elevation marker is shown as a circle with an arrow pointing toward the elevation. After fixed the column shape the 2nd step to draw the column. A: I meant frequently asked questions about dimensioning. Here are some of the symbols you will see on mechanical plans: Architects and builders draw reflected ceiling plans (RCP) to show the dimensions, materials, and other key information about the ceiling of each of the rooms represented on the blueprint. If you are using arrows, try to keep them all at the same angles. Reference markers are labels on a drawing that indicated where the drawing is taken from and what it is showing. Keep in mind that scales can vary throughout a set of architectural prints, so check each page and. , is created by architects, engineers, and designers to lay out all the construction specifications of a house, such as dimensions, The number of details that must be included in a complete set of blueprints is so large that architects reduce the information on the drawings to a set of standardized symbols and, Appearance (for instance, a bathtub looks like a bathtub), Conventions (double lines are commonly used to denote walls). View more posts. Dimension lines are used to identify exactly where the dimension begins and ends. This makes sense, since every interior dimension should be tied to its closest column line. That was a run through of what I learned in my first few months being a structural engineer fresh out of University all those years ago. And now the philosophical answer: I remember reading, around 15 years ago, a story about Richard Meier telling his staff to make it look like an architect did it. Whatever we may think of Meier now, this advice remains sound. Stairs are customarily indicated by parallel lines with their measurements. [4] All these industry standards and more can be found in the Handbook of Construction Tolerances by David Ballast. The beauty of a structure is depending on the position of the column.

Thank you for helping keep Eng-Tips Forums free from inappropriate posts.The Eng-Tips staff will check this out and take appropriate action. A dimension is shown indicating how far each corner of the building is in relationship to the property line or boundary. In my drafting days, I used to approach dimensioning as a sort of puzzle. That is to communicate our ideas or design as clearly as possible. Good dimensioning isnt hard, not like, say, mastering Revit. A window is usually denoted with three lines, vs. a walls two parallel lines. The arrow shows the direction that the section is being taken. Surveyors use the plot plan shown below to set up the corners and perimeter of the building using batter boards and the line stakes. The length of the properties boundaries are also shown. Electrical drawings: These drawings show the electrical systems of the building, including the locations of outlets, switches, and lighting fixtures. Dimension Lines Dimension lines can be shown many different ways, such as shown here with arrows as end points or hash marks. Dont get me wrong: I think Revit is a wonderful modeling software that does amazing things. Thanks. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam.

As you can see in the example site plan below, the driveway is shown entering off of the roadway. Architects and designers work with the floor plans, and youll also see exterior and interior elevations, and reflected ceiling plan (RCP). You will also use a floor plan (or section) to show junctions or areas where you will reference a detail. Appliances and fixtures, such as toilets, sinks, and bathtubs, are drawn to scale with a thin line, and resemble the item they symbolize. Dimensioning provides accurate sizing on objects in the drawing. Architectural, structural and all mechanical drawings should have the same column line references. These alignments enable component sizes to change without any impact on the gridlines, for example, a column can be increased in size, without the need to shift its centerline. If you are in the construction industry or renovating your own house, the ability to read structural drawings and plans is a very important skill to have and its relatively easy to learn. The Face Sheet will also have the name of the project (often simply the project address or if the developer has started to brand the development, it may be the projects brand name). Dimension lines are used to indicate the distance between two points. But it will be hard enough keeping Revit from dimensioning everything to the 256th inch, so you may want to let it win this one. only the structural slab thickness is shown (in this case 250mm thick or 9.84inch thick for those playing at home in the US). on what you'd like to see from your CCA community at. Symmetrical parts. I have also seen industrial plants laid out in a coordinate system. Architects and designers work with the floor plans, and youll also see exterior and interior elevations, and. Sorry for any inconvenience. Always keep in mind, annotation and labelling are to ensure clarity of the drawing. A: The 0'- is annoying and unnecessary, and it takes up valuable space in a dimension string. to get occasional emails with new content and resources.

Please do not use this video as a point of reference to make engineering decisions as I am not an engineer. The dimension line is offset slightly way from the object, and does not touch it. Similarly, dont repeat dimensions from details, such as the widths of column enclosures. If the drawing is not printed on the correct sheet size the intended drawing scale is not accurately represented. Hidden Line: Lines used to show interior detail that is not visible from the current outside view of the part. Where will those two inches come from in our dimension string? The following image is a snapshot of another typical office floor however the structure is a composite steel floor system. Depending on which hemisphere youre in, this will determine which exposure get shade and how the sun hits various aspects of the structure, effecting its heat gain or loss. You will inevitably encounter situations where not following a tip is the only way to solve a problem. This is usually found in the title block at the top of the drawing. In order for structural drawings to fit on a manageable sized drawing sheet, the drawing is usually a small fraction of the real-world size. These details explore different ways to achieve a garage conversion, looking at wall detail options, floor upgrade options and roof upgrades. A: Why, yes, there is. Numbering the grid line. Later, when the project is in construction, if the information isnt clearly presented, the contractor will issue RFIs asking you to clarify all the dimensions that are ambiguous or contradictory; responding to these RFIs will take more time than dimensioning the plan correctly in the first place.
