What are a construction project's stages?

To finish our construction projects, we use either the Design-Build model, the Design-Bid-Build model, or an Integrated model. Read on to find out how and why we tailor our construction process to each client and how working with us is like.

Design-Bid Build

The Design-Bid-Build construction method is one of the most well-liked because it gives customers the opportunity to provide constructive feedback on the project. There are seven steps in the Design-Bid-Build model. This is how it works:

 Step 1: Design

The client submits a project for bidding during this phase. The client is aware of the project's objectives and timeline in general. The client then hires a freelancer to create the necessary construction documents. After that, the client sends the documents to potential contractors and chooses the best bid.

Step 2: Pre-Construction

In the Design-Bid-Build model, the pre-construction phase consists of the following steps:

Approve the budget.

Make contact with representatives from the private sector, the local government, and the city to inform them.

Make any additional construction site modifications or plans.To minimize disruption, coordinate schedules with the community and private businesses nearby.Assess any requirements with a equipment inventory.The client makes any final decisions and performs any last-minute checks at the conclusion of this procedure. A Notice-To-Proceed is issued by the client following the completion of these steps, allowing contractors to begin the subsequent phase.

Step 3: Procurement

During the Procurement phase, we work with all contractors to establish a baseline schedule for successfully completing the project phases. We meticulously plan the project's scope and steps because some contractors' roles are directly related to those of other contractors. We delegate managers, team leads, and other project-related roles during this phase.

 Additionally, during the procurement phase, we note any materials with lengthy lead times that could cause the project to be delayed. We keep an eye out for things like bridge beams, steel beams, and plumbing supplies because they can take longer to arrive.

Step 4: Construction

The design becomes a reality during the construction process. Subcontractors and contractors collaborate to finish the design in accordance with the specifications in the construction documents.

We will schedule weekly, biweekly, or monthly review meetings with project stakeholders from both organizations to keep the project on track. We go over the work that has been done thus far and look ahead to the project's goals in these meetings.

Step 5: Commissioning

Following the completion of the construction phase, we move into the Commissioning phase, where we inform anyone who will use the new website about the new features. For instance, if we were to construct a brand-new building for an office, we would hold a commissioning meeting for the office staff and administration.

There are two kinds of commissions that we do: horizontal and vertical commissioning. A certificate of occupancy is issued by the state legislature as part of vertical commissioning, allowing the client to operate the building. Anything that doesn't happen in vertical commissioning is included in horizontal commissioning.

Step 6: Owner

Occupancy In order to get the client ready for moving into the new building, we hand over all building management to them during this phase. Additionally, we use this time to respond to any last-minute inquiries. After that, the project is finished!

Step 7: Project Closing

Our project closing phase primarily consists of an internal evaluation of our project's overall efficiency. To identify areas for improvement, we hold project meetings with our team leaders, managers, and contractors. Additionally, we highlight project strengths that we intend to implement.

 

Because contractors and designers collaborate, the Design-Build process differs slightly from the Design-Bid-Build method. The key differences are as follows:

 

Step 1: Design

Instead of having two separate contracts, the client issues a Request for Quote (RFQ) during the Design phase that includes both the design and construction services. By allowing the designer to work together to bring the design to life, this strategy makes the process more efficient.

 

Step 2: Pre-Construction

Both the Design-Build and the Design-Bid-Build processes have a checklist of things to do before starting the Construction phase, so the Pre-Construction phase is similar. The primary distinction is that because they all work under the same contract, the contractors may internally coordinate all subcontractors.

 

Step 3: Procurement

Compared to working with external contractors, the procurement phase of the Design-Build process is more effective because all contractor-designer communication takes place within a single organization. Materials time estimates are still included in the procurement phase.

 

Step 4: Construction

The contractor can begin construction as soon as they receive the NTP. All team leaders participate in weekly, biweekly, or monthly meetings to provide project updates and time estimates. In the Design-Build process, the Construction phase has the advantage of having fewer subcontractors, which may reduce the number of meetings required.

 

Step 5-7:

Steps 5-7 in both construction models generally follow the same procedure.

 

Integrated Model Recently, construction companies began employing a hybrid model that combines the Design-Build and Design-Bid-Build methods. Before working with the contractor, the designer can use the Integrated Model to design a portion of the final project during the Design phase. By keeping the services under a single contract and working together to adjust the specifications if necessary, this hybrid model combines the best features of both processes. In the hybrid model, managing contracts with subcontractors relies heavily on the construction manager.
