5 Stages of Architectural Design Process

You might have wondered what are different stages while providing Architectural Design Services. Be it hotel, residential design architecture, commercial, warehouse, storage, industrial or retail, etc. In this article, we will explain all phases that are involved in a design-build of a new construction/development project.

There are typically 5 stages of architectural design involved in a design-build of any project.

These 5 phases/stages are

PRE-DESIGN (PD)

The first objective is to get-together with a client and determines overall project vision and goals. There are some key areas to discuss the project – scope, features, purpose, and functionality.

SCHEMATIC DESIGN (SD)

In this phase, we do series of rough sketches/drawings that illustrate the basic concepts of the design. Also, initial research of local compliance and regulations are completed at this time.

DESIGN DEVELOPMENT (DD)

This phase involves finalizing the design and specifying items such as materials, window and door locations and general structural details.

CONSTRUCTION DRAWINGS (CD)

By now we have a final design. We can begin preparing construction drawings/blueprints, notes, and technical specifications necessary for bidding, construction, and permit application.

CONSTRUCTION

During this phase, we will build as per the design intent. Also if there are any changes, we discuss changes and options with the owner. It ensure that alterations are compatible with owner’s vision for the project.

1 – PRE-DESIGN (PD)

The first objective is to get-together with a client and determines overall project vision and goals. Irrespective of the industry being residential, healthcare, industrial, hospitality etc., there are some key areas to discuss the project –  scope, features, purpose, and functionality.

In this phase, we carry out

  • Client consultation
  • Existing conditions survey and documentation
  • Photographs
  • Measurements
  • Compile existing drawings if any
  • Prepare high-level base drawings
  • Statement of probable build/construction cost
  • Programming space and use
  • Code review

This phase ends with owner’s decision to move forward with a project.

2 – SCHEMATIC DESIGN (SD)

In this phase, we do series of rough sketches/drawings that illustrate the basic concepts of the design.  Also, initial research of local compliance and regulations are completed at this time.

At the end of this phase, we deliver

  • Floor plans of all levels with generic openings and plumbing fixtures
  • Exterior building elevations with representative openings and finishes
  • Building cross-section
  • Typical wall section

And we move to the next phase with the owner’s approval.

3 – DESIGN DEVELOPMENT (DD)

Design development collects the results from the schematic design phase and takes them one step further.

This phase involves finalizing the design and specifying items such as materials, window and door locations and general structural details.

At the end of this phase, we deliver

  • Floor plans with a proposed basis of design openings and plumbing fixtures
  • Overall dimensions
  • Structural grid dimensions
  • Interior wall dimensions
  • Exterior elevations with a proposed basis of design openings and finishes
  • Additional building sections
  • Wall sections at all typical conditions
  • Typical details
  • Additional details to establish a basis for design products

Now we have given shape to project ’s vision through drawings and written specifications.

4 – CONSTRUCTION DRAWINGS (CD)

By now we have a final design. We can begin preparing construction drawings/blueprints, notes, and technical specifications necessary for bidding, construction, and permit application. Construction contractors will use these detailed drawings and specifications to prepare for the construction.

In this phase, we deliver

  • Floor plans fully annotated
  • All dimensions
  • Room, wall, door, and window identification
  • Section and detail indicators
  • General notes and detailed notes
  • Exterior elevations fully annotated
  • All building sections required for construction
  • Wall sections at all conditions
  • Details fully annotated
  • Structural plans, details, and notes
  • Plumbing plans, schedules, details, and notes
  • HVAC plans, schedules, details, and notes
  • Electrical power and lighting plans, schedules, details, and notes

And we move to the final phase

5 – CONSTRUCTION

Finally, the construction is underway.

During this phase, we will build as per the design intent. Also if there are any changes, we discuss changes and options with the owner. It ensure that alterations are compatible with owner’s vision for the project. This is the last phase and at the end of this phase, a project is ready for the use/occupancy.

TRANSFORMING CONSTRUCTION PROCESS WITH LEAN CONSTRUCTION

Transforming Construction Process with Lean Construction

TRANSFORMING CONSTRUCTION PROCESS WITH LEAN CONSTRUCTION

Lean construction is derived from the concepts of lean manufacturing, and it combines operational research and practical construction design development. Many lean manufacturing practices and principles for end-to-end design are implemented in the lean construction process. To simplify, lean construction is about managing and improving construction process to satisfy customer needs and achieve quality, schedule delivery, safety and profitability.

Why Lean Construction?

There are three key priorities in any construction process:

  1. Keep the work flowing so that the workforce employed are always productive
  2. Reduce inventory of tools and materials
  3. Reduce waste and inefficiency inefficiency

To simplify, optimal usage of materials, time and efforts are crucial in the construction process for generating value in the process. Moreover, for any project, the system needs to collaborate business owners, AEC, contracts, facility managers, workers and various other teams at the early project stage. Lean construction identifies the gaps and aims to benefit the overall construction plan.

Lean construction follows the lean production approach, but it is differently perceived during practical implementation. Various workflows are integrated into the construction planning process to align the supply chain to maximize the value and minimize the waste. Toyota and other such companies have pioneered the lean model using TQM, SPC, and Six-Sigma to meet customer demands and improve business profitability.

How to implement Lean Construction?

We can implement Lean construction by using CPM and work breakdown structure. Other tools and methods are also used like Last Planner System, Target Value Design, and Lean Project Delivery System.

There are also toolkits available to implement Lean construction like:

  • Lean Design: BIM, A3, Process Design, Kanban
  • Lean Supply: JIT, 6S
  • Lean Assembly: Value Chain Mapping, Visual Site, Daily Crew Huddles

The lean principles can be implemented entirely and efficiently by focusing on refining the whole construction process. It requires all teams, stakeholders to be committed, involved, and work to overcome obstacles that may arise from traditional contractual arrangements.

Each departments need to follow below guidelines:

For Construction:

  • Clear communication of project plans
  • Training the team to improve teamwork and multi-skills
  • Daily progress reporting and improvement meetings
  • A well-motivated, well-trained, flexible and fully engaged workforce

For Design:

  • Leverage Virtual Reality or 3D design to adequately visualize and define the project requirements from the customer’s perspective
  • Value Management to get better clarity and focus on client value
  • Use of integrated design and build arrangements (including partnering) to encourage close cooperation between designers, constructors, and specialist suppliers
  • Design for Standardization and Pre-assembly – both of components and processes to achieve higher quality and cost and time savings.

For Procurement:

  • Supply chain management and rationalization of the supply chain to integrate all stakeholders to contribute to delivering the overall customer value
  • Transparency of costs – elimination of waste in both processes and activities requires a clear and complete understanding of costs to ensure right decisions on customer value.
  • We must address confidentiality of expense and cash flows
  • Eliminating the boundaries between companies by partnering and getting more contribution to achieve a common goal

For Construction Planning:

  • Establish ‘best in class’ construction methods and outputs
  • Formation of a stable project program, with precise identification of critical path
  • Risk management – to manage risks throughout the project

For Logistics:

  • Just-in-time delivery of materials to the point of use eliminates the need for on-site storage and double handling
