Sometimes the best plan is having no plans at all, I know this is not relatable with the topic above but I am saying it anyway. If you are a regular reader of the site, you may already know that I really have a craving for wisdom and I genuinely love the way you see me. Coming to the topic, building plans are the cornerstone of every home construction project around the world. We need a proper plan in mind and on paper before going to execute anything. And this article will let you learn and go through the steps involved in such processes like supporting building plan types, especially in the cases of home construction. Read and rise everyone, love you deep 😊
1. Supporting and Detailed Plan Types
A. Structural Plan:
An Explanation:
Structures are the core of a building and these plans are just the drawings that show everything about them like beams, columns, slabs, foundations are quite a few things that hold a structure together. In an X-ray perspective, it is the skeleton of any architecture, higher the bond, higher the building stability.
The plan excludes the furniture and interior paint colors; it primarily focuses on the things that keep the wall steady and the floor from falling apart. The plan is not much eye catchy but it holds the strength and balance of an architecture.
It shows how everything connects and where the loads compound mostly. Every detail or dimension, and notes are there to make sure the structure can withstand people, load and sometimes the structure itself.
The plan should be signed and approved by licensed structural engineers to proceed further with the construction of any building. Without a permit the project has no life.
B. MEP Drawings:
An Overview:
MEP drawing causes designing and construction to be accurate and efficient and error-free. When the drawings are accurate, they help avoid clashes that can prove costly to rectify during the construction stage of a project for all parties.
a. Mechanical/HVAC Drawings:
These drawings illustrate the HVAC layout for ductwork, air distribution and all ventilation systems toward the creation of the highest efficiency possible. Mechanical drawings show the exact locations of the air handling units (AHUs), the chillers and the condensers to prevent any conflicts with the architectural, structural, electrical or plumbing work. Careful arrangement of these mechanical components in this manner increases the comfort and energy efficiency of the building.
b. Electrical Drawings:
Which include power distribution and wiring diagrams as well as lighting diagrams. These drawings show the layout of the switch gear, circuit breakers and electrical panel on each floor. All systems and spaces within the building must be supplied with power on electrical drawings.
c. Plumbing Drawings:
It depicts the building’s water supply, drainage and gas distribution systems and they can be thought of as the building’s lifeline. They include drawings of the layout of fixtures, sinks, toilets, fire sprinklers and specifications. These drawings are to ensure that the water flows freely and without any blockage or leakage and modern technology is available to determine the amount of water consumed and prevent wastage.
d. Fire Protection Drawings:
These drawings show the precise location of sprinklers, smoke detectors and fire alarms; maintenance staff use these to ensure that the devices are in working order and ready to respond in the event of fire. These designs are in compliance with current fire codes. Having accurate and well-designed fire protection drawings will greatly assist in the reduction of fire incidents and also keep the fire fighting equipment in readiness.
e. Coordination Drawings:
They are mainly used for clash detection to ensure that mechanical, electrical and plumbing systems do not conflict with each other, nor intrude into the spaces and elements of the architecture and structure. These may also serve to improve the spatial coordination of disciplines. Coordination drawings go a long way in ensuring that the building is optimally integrated to work as a single unit.
f. Penetration Unit:
The purpose of penetration drawings is to show locations of block-outs and sleeves. They also prevent construction mistakes by creating predetermined penetration points while allowing conflict-free construction between internal and external trades and disciplines.
g. MEP Shop Drawings:
Fabrication and installation instructions are provided in the mechanical, electrical and plumbing (MEP) shop drawings or takedown drawings. Detailed drawings allow for purchase and prefabrication, enabling improved manufacture, less wastage and better quality. One of the main purposes of MEP shop drawings is to reduce construction mistakes on site and save time and cost.
h. Pipe Spool Drawings:
It depicts prefabricated pipe sections for mechanical construction. These drawings save time and the accuracy of construction. One of the main purposes of a pipe spool drawing is to reduce welding and assembly errors.
i. As-Built Drawings:
During the construction process, changes may happen that cause the as-built to differ from the construction set drawings. As-built drawings show the actual built location of all mechanical, electrical, plumbing and fire protection systems for future operations, maintenance and renovations to the facility. These drawings are very useful for refurbishment and maintenance tasks, including examination of precise details. As-built drawings are a reference for future projects.
C. Detailed Drawings:
a. Construction Detail Drawings:
The drawings indicate how to construct walls, roofs, openings, structural connections and other components. The drawings include the materials, sizes and relationships between them that are required to carry out successful construction.
b. Structural Detail Drawings:
They detail the framework. Which includes the beams, columns, foundation and reinforcement layouts. These drawings explain how these parts will support the building and fit together.
c. Electrical and Mechanical Detail Drawings:
These also layout electrical, ductwork, plumbing and other service systems, so trades can coordinate and install equipment without conflicts or errors.
d. Interior Detail Drawings:
The interior details utilize custom furniture, cabinetry, floor patterns, partitions, trim and other architectural features to precisely specify and fabricate finishes on-site upon delivery.
e. Joinery Drawings:
These describe how to construct wooden items, such as doors, windows, millwork, stairs and built-ins including the joints, profiles, lamination and installation methods.
f. Landscape Detail Drawings:
Landscape drawings are used to help design landscape features along paths, planting areas, retaining walls, paving, water features and grading so they all work together.
g. Plumbing Detail Drawings:
These drawings indicate that water lines distribute systems, drain pipes and fixtures vent and confirm they are sized, routed and compatible with the design.
h. Door and Window Detail Drawings:
These document the frame profiles, detail the materials, specify the hardware, weatherproof the doors and windows and install them to ensure proper performance.
i. Façade Detail Drawings:
They show the various layers comprising the building’s outer skin, including layers for cladding, insulation, structural elements, joints and architecture that give the façade its appearance, strength and weatherability.
j. Staircase Detail Drawings:
These drawings also show the geometry of the stair threads, risers, landings, handrails and other elements that support the stairs. They show the detailed forms of woodwork and concrete.
D. Reflected Ceiling Plan (RCP):
An Explanation:
A Reflected Ceiling Plan (RCP) is a room ceiling plan drawn as if it were reflected within a mirror above the floor, and can typically be seen as a plan view turned upside down. The plan shows all lighting fixtures, fans, beams, soffits, HVAC vents, sensors, and ornamentation that are attached to or recessed into the ceiling. Whereas a floor plan shows how a room functions at floor level, an RCP indicates how a ceiling coordinates functionally and visually with that function.
Why RCP is Important:
a. Optimized Lighting & Ambience:
RCPs help the designer determine the location of lights to ensure a sufficient level of light, interest in focal points, and the right mood.
b. Smooth Coordination of Systems:
In a high-tech building, where lighting, ducts, detectors, and speakers may all be ceiling-mounted, an RCP includes all of these upon one drawing to coordinate their locations.
c. Design Consistency with Aesthetic Clarity:
Designers, visualizing all elements beforehand, can ensure symmetry maintenance. They can reduce visual noise. Designers can achieve a better aesthetic.
Ultimately, a clear RCP will prevent costly mistakes throughout installation, as well as large delays during construction.
An RCP considers the room’s intended purpose, ambient light, and ceiling constraints.
The steps in drawing an RCP are:
- Plan ceiling zones and lights according to the layout of the space.
- Symbols for ceiling lamps, pendants, recessed lights, spotlights and track lights should be spaced and aligned accordingly.
- Show any beams, soffits, false ceilings etc. which will affect the installation.
- Vent and duct locations should not interfere with lighting and glare, heat, or shadows on the sign.
- Place switches at entrances and define different zones for lighting.
- Dimensions and a symbol legend must be included in order to be implemented.
