When you begin a commercial construction, refurbishment, or fit-out project, it’s easy to lean on the traditional tendering model. At first glance, appointing a designer and then gathering quotes from several contractors may seem like the most competitive and cost-effective option.
However, in reality, this fragmented process often results in miscommunication, project delays, cost overruns, and even conflict between teams. These issues can quickly derail even the most well-planned projects.
At SL2, we’ve worked with both traditional and integrated delivery models. Through our Design & Build expertise, we’ve seen firsthand how outdated the tendering process has become particularly in today’s fast-moving, outcome-focused environment. Here’s why we believe it’s time to rethink the process.
1. Lack of Accountability = Greater Risk
In the traditional tendering model, responsibility is divided between architects, consultants, and contractors. As a result, no one holds full accountability for the success of the project. When challenges arise, it becomes easy for different parties to pass the blame, which only increases delays and confusion.
In contrast, our Design & Build model provides a single point of accountability. At SL2, we take full ownership from concept to completion. This structure gives you one experienced team managing everything, from design and planning to delivery and execution.
2. Design and Cost Are Often Misaligned
Quite often, traditionally managed projects run into trouble when the proposed designs exceed the budget. This misalignment leads to costly redesigns, frustrated stakeholders, and strained relationships.
By comparison, our Design & Build team works collaboratively from the outset. From day one, we balance creative ambition with financial practicality. SL2’s designers and project leads ensure that your vision stays aligned with your budget long before any work begins.

3. Slower Timelines and Lost Momentum
Following the traditional route often means waiting. After finalising the design, you must tender the project, wait for bids, evaluate them, and then appoint a contractor. This can add weeks (or even months) to your timeline.
Meanwhile, our integrated approach speeds things up. As we develop the design, we’re also planning delivery and logistics in parallel. As a result, you benefit from faster mobilisation, earlier starts, and quicker project completion.
4. More Communication Channels = More Room for Error
Each additional stakeholder introduces more potential for errors. Misaligned specs, delayed decisions, and conflicting inputs can all contribute to costly setbacks.
Fortunately, Design & Build simplifies communication. At SL2, our collaborative team structure ensures that everyone remains aligned throughout the project. This way, we reduce the risk of mistakes and keep the project on track.
5. Fragmented Relationships Can Lead to Conflict
Splitting design and construction across separate contracts often results in conflicting priorities. This division can create an “us vs. them” mentality that hinders collaboration and undermines outcomes.
To avoid this, SL2 fosters a shared-goal culture. Our team operates as a unified force, where designers and builders work together with a common objective: your success. Consequently, we deliver projects with less friction and more alignment.
