What are Construction Drawing Services?

3d shop drawings

Construction Drawing Services for building designs facilitate in automating, streamlining and organizing construction documentation process. Home builders along with architectural companies seek competent construction drawing services to resolve productivity problems.

It is found that most building projects end up with design rework, involving huge money and time. Sometimes, the costs of major civil engineering project can go up to 20%. The most common causes of rework include omissions, errors, operational changes, fabrication glitches and project enhancements. Seeking shop drawing services from a competent BIM company in USA facilitates construction documentation, resolving construction and design issues.

A variety of construction drawings are used in construction projects, including architectural drawings, structural, electrical, plumbing and mechanical shop drawings. These building drawings provide competent layout floor plans to convey the perspective of the designer to the layman at the site. The ‘detailing drawings’ point out the overall building appearance of the structure to find out accurate measurement.

5 major construction drawings 

1. Architectural Drawings

Architectural drawings are the primary drawings used for construction. All design details of the project like site plan, set out plan, elevations, sections, etc. are included in the architectural construction drawings. Some of the common architectural drawings provided by top construction company involve:

  • Site Plan – This primary drawing helps to mark out the plan on the ground. This helps to represent the location, orientation as well as the information regarding the topography, landscaping utilities and site work.
  • Working Plan – These working drawings in architecture provide the information of the horizontal dimensions of the building, wall thickness, clear spaces within the building as well as the column locations. Further, the work drawings show the openings of the building  doors, windows and ventilators.
  • Section Drawings – These drawing represent the construction of materials for the measurement of the building and structural components like slabs.  The drawing shows how the building is cut through a vertical plane.
  • Elevation Drawing – The drawings show the information about openings, shape of external surfaces as well as the building height. These are created for retaining an aesthetic view of the construction.

2. Structural Engineering Drawings

Structural drawings form the backbone of building construction. These contain all information pertaining to the structural conflicts on a building, comprising of various drawings with minute details. Cost-effective engineering drawing services from a competent construction company enable accurate door and, window schedule, floor framing and material scheduling. Basic structural drawings encompass:

  • General Note Excavation Drawing – The drawing represents the dimensions of footing excavation, column position, footing plan as well as column grid lines.
  • Plinth Beam Plan – This structural drawing signifies the position, dimension and section of the plinth beam with the details of reinforcement in plinth beam.
  • Lintel Beam Design – This construction design drawing represents the dimension, location and sections of lintel beam and reinforcement details in lintel beam.
  • Roof Beam & Shuttering Arrangement- This is a representation of the details of reinforcement of roof beam, its section and shuttering details.
  • Roof Slab Layout – Here, the reinforcement details of roof slab, sections and openings in the roof for stairs and skylight are represented.

3. Mechanical Shop Drawings

BIM engineers produce the mechanical shop drawings to resolve clashes through duct re-routing, resizing and modifying elevations. Detailed shop drawings generated from the BIM model help in shop drawing installation and pre-fabrication.

  • Installation Drawings – Developed from coordinated detail drawings, installation drawings help to install mechanical parts. They are significant for complex installations of data centre, plant rooms, ventilation system, under-floor heating, etc.
  • Block-out Drawings – These drawings contain essential information about building assembly and are located towards the bottom of the drawings.
  • Sleeve, Insert, Hangar – Sleeve drawings help to insert sleeves on the pipe of your choice. Frame hangars complete design drawings for an industrial building with elevated crane.
  • Spool Drawings – These drawings act as a guide to plumbers for understanding what they are encountering. A pipe gets split into different sections called spool to furnish the information of all parts welded together in a shop on a single drawing.

4. Electrical Drawings

Electrical drawings show the details of the electrical fixtures, position of fan, light, switches, etc. The drawings also represent a load calculation, tapping of electricity, wiring and other interventions like AC and UPS as well as AC and its mechanisms. Examples of electrical BIM drawings include:

  • Electrical Power Layout – This shows the information about power, lighting as well as communication for an engineering project. The plot shows the building location and electrical wiring on every floor.
  • Sleeve Drawings – Sleeve in construction helps to access the material for a pipe or conduit wiring. To take an instance, the sleeves required to be placed in the walls before the placement of conduits.
  • Prefabrication drawings – Prefabricated electrical drawings integrate prefabricated mechanical and electrical components into a module for off site manufacturing.
  • Data cable and Fire Alarm drawings – Communications channels are permitted with cables, power-limited fire alarm cables and low-powered network broadband communications cables.

5. Plumbing Drawings

Plumbing drawings give the location of sanitary and other piping details for water supply as well as fixtures. These drawings represent the line size & location, hot-water capacities, drain locations and routing.

Building Drawings for Smooth Execution of Construction Workflow

The significance of building MEP drawing is marked in the smooth operation of construction workflow. It is to be remembered, that if insufficient information is communicated by the construction drawings, it could lead to a hampered design implementation.

The main aim of the construction drawings, popularly called plans, blueprints, and working drawings show us what is to be built, while the specifications emphasize on materials, installation and quality standards. Architectural, engineering and construction professionals get all dimensions, details, notes and graphic information from the construction drawings. Be it a 3d floor plan, exterior or interior elevation or other details, showing how the buildings would be put together, the construction professionals visualize the entire picture of the construction through BIM coordination drawings. 

Currently, top BIM modeling services are facilitating AEC professionals by providing the right tool and the insight to efficiently plan, design, construct and manage building infrastructure. The engineers are working with building MEP drawings, Heating, Ventilation  & Air Conditioning shop drawings, mechanical fabrication drawings, etc. using Building Information Modeling.

Let’s now take a look at the different building drawings created through BIM modeling for smooth execution of construction workflow:

  • Building MEP Drawings – MEP shop drawings derived from the 3D BIM model are produced by combining mechanical, electrical and plumbing services. The drawings enable fabrication, manufacturing, installation, assembly, as well as the maintenance of mechanical, electrical and sanitation components of a building. Using top MEP modeling services, parametric modeling and library creation could be accomplished for HVAC and MEP components.
  • BIM Coordination Drawings– Coordination drawings are reproduced through BIM model, showing horizontal and vertical dimensions essential for avoiding interference with structural, framing MEP rough-ins, fire protection, elevators, and other floor and wall penetrations. BIM coordination drawings help various services to coordinate with each other based on design.
  • MEP As Built Drawings – As-built drawings constitute to be a revised set of drawings submitted by a contractor, after completing a project or a specific job. The final as-built drawings encompass all details, as well as the modifications made during the building phase of a project. Though prepared by the contractor, Mechanical, Electrical and Plumbing as built drawings are more like interpolations done for construction purposes. These help to create effective construction documentation, highlighting changes in red.
  • Engineering Assembly Drawings – Engineering assembly drawings are also supported through Building Information Modeling. The drawings demonstrate the process through which sub-assembly drawings, detailed parts, standard components as well as other specifications assemble in a unified way.
  • HVAC Shop Drawings – The shop drawing constitutes to be the contractor’s drawn version of the information shown in construction documents. HVAC shop drawings are more detailed compared to construction documents. Shop drawings obtained from the BIM model facilitate in elucidating fabrication or installation of various items to the manufacturer’s production or contractor’s installation crew.
  • Mechanical shop drawings– Accurate mechanical shop drawings produced from the BIM model provide comprehensive information, acting as a cornerstone for accurate fabrication and installation. The drawings facilitate manufacturing, fabrication, installation, assembly and maintenance of mechanical components within a building.
  • Mechanical Fabrication Drawings –  AEC project stakeholders also opt for these drawings from top BIM modeling service providers. The detailed fabrication drawings  are virtual assembly drawing, when a number of items are assembled as a fabrication. The fabrication drawings encompass a list of materials, identifying everything to be used to build up the fabrication.
