It gives the reader a visual representation of the structural framing requirements for that level. For instance, a C with an L through it is a center line, and describes that a window is centered, with equal distance on either side. A good option is vertical, horizontal and 45 degree angle only if possible. Which one is easier to read? All of these elements are non-structural so they dont appear at all on the structural drawing. Reference markers are labels on a drawing that indicated where the drawing is taken from and what it is showing. The use of grid lines is standard on any construction drawings. Dont get me wrong: I think Revit is a wonderful modeling software that does amazing things. The elevation marker does not always show a reference number to the drawing sheet. This category only includes cookies that ensures basic functionalities and security features of the website. It is very important to understand scales when measuring off from printed drawings. Start with Column Lines. 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). The symbols are also drawn to scale so you will get an accurate idea of how elements of a room are configured in the space. The Difference Between Block Foundations and Poured Foundations. In industrial plants, I run into columns that are off column grids all the time. First, the practical answer: A well-dimensioned plan doesnt necessarily take more time than a messily dimensioned one, and is less likely to have mistakes. Owners wont be willing to pay for such precision unless theres a damn good reason for it. Gridlines are the major organizing element of a building and provide the design and construction team with clear reference points, location, and dimensions. Work built in a shop under controlled conditions, such as millwork, can be built with considerable precision, while work built on site, under whatever conditions are prevailing at the time of construction, can be built much less precisely. Dotted and dashed lines can indicate hidden items, or ceiling height changes, wheelchair turning circles and so on. Watch this Video for a quick overview of a complete set of Construction Drawings. It thinks nothing of providing dimensions to the nearest 256th of an inch (0.004 inches), which is roughly the thickness of two sheets of standard bond paper. The recommended approach is for there to be one locked source-of-truth gridline matrix that is referenced in all other construction documents. Following are the construction drawings used in any project. The section marker is shown slightly differently to an elevation marker with a larger arrow. Scroll to the end to download this as a handy PDF Guide! It is important to keep your dimensioning consistent in terms of both style and format. 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. In this case, we see that they are placed between a window (the triple line indicated by a diamond), and an interior architectural wall (the double line). What other articles do you have that support this? Reading a set of construction drawings requires that you learn basic drafting guidelines and the symbols that are used to convey meaning, much like a traffic sign tells you what to expect up ahead. [4] All these industry standards and more can be found in the Handbook of Construction Tolerances by David Ballast. Because without column layout its impossible to locate the actual location of the structure. A heavy line will represent cutting planes and contours of an object, like a wall for example. . 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. But when it comes to dimensioning, it doesnt know anything about tolerances and precision except what you tell it. As you look at symbols such as the diamond for window, look for important abbreviations that describe it, such as EQ, or equal. This will help you understand the dimensions of what the symbols are describing. Grid Lines To find the Column Location- Mark the Location first by peripheral Lines. Some other articles which an engineer just starting out may find interesting include, https://sheerforceeng.com/how-to-become-a-structural-engineer/ The problem with line weights in construction drawings is that they can be misinterpreted due to the varying thickness of the lines .

Dimension lines are lighter than line weights used for walls and structural elements. All the drawings together will provide for a fully constructed project, covering everything from the structure to the mechanical systems. Total Station Surveys are conducted to plot the center line marking over the plot. These plant cad blocks available in both metric and imperial versions. Consider why dimensions are being added to the drawing. The structural drawings on the other hand appears to have a bit more going on in this area, with slab thicknesses indicated (180-200mm or 7.08-7.87inch) as well as some additional dashed lines this we will get into more detail later on.

A: Im glad you asked that. These standard details are usually typical repetitive details which will be adopted at multiple locations on the project. An open string, on the other hand, leaves at least one dimension in the string unspecified (or open). This means that a grid reference of E2 on the architectural drawing should be the exact same location in the building as the grid reference E2 on the structural drawing (you sank my battle ship, or in this case, column!). Does it read easily? Location mapshows where the property is located on a Google map or other source. A: Why, yes, there is.

So, a floor plan drawing would be A100 for example, then if you had a number of floor plans A101, A102, A103 and so on. 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. A set of elevation drawings may be A200, A201, A202 and so on. First we will go through the general drawing elements which are usually common across the disciplines. The beam's minimum width is 200 mm. The plan which contains column size & position is called acolumn layout plan. Break lines used in cylindrical and tubular objects. North Point Indicator: In the case of a floor plan, this shows the orientation of that plan in relation to true north. The scale is always shown on the same page as the drawing, either under the title or below an individual drawing.

On building plans, gridline heads should be shown at both ends of the gridlines, on enlarged or partial plans gridline heads are permitted to be shown at only one end. It is our goal to provide clear answers to issues of concern to the Institutes membership and share case studies and best practices. Things such as dimensioning.
