Ashe Construction has embarked on a comprehensive journey to reduce waste by introducing a systemic approach outlined in their Road Map to Net Zero. This involves evaluating every phase of the construction process—from procurement to project completion—to identify areas where waste can be minimized. They are working closely with subcontractors to ensure materials are used efficiently and to find ways to reuse or recycle surplus. By focusing on education and accountability within their teams, they aim to foster a culture of sustainability across all their projects.
Can you break down the different types of waste commonly observed on construction sites? Which are prioritized for reduction?
On construction sites, waste can be categorized into several types, including packaging waste, single-use plastics, and leftover materials from over-ordering. Among these, packaging waste and the unnecessary use of plastics are key priorities for reduction. By streamlining packaging processes and exploring alternatives, Ashe hopes to make a significant dent in these waste streams. Another critical focus is on the effective management of leftover materials, ensuring they don’t end up in landfills but are repurposed effectively.
How do you plan to raise awareness among subcontractors about the broader impacts of construction waste?
Raising awareness among subcontractors involves a combination of education, collaboration, and incentive systems. Ashe has initiated workshops and on-site training sessions to illuminate the environmental and financial impacts of construction waste. By fostering a sense of shared responsibility and rewarding those who actively contribute to waste reduction, they encourage subcontractors to adopt more sustainable practices, which can then be applied across other projects they work on.
What role do subcontractors play in achieving Ashe Construction’s Net Zero targets?
Subcontractors are pivotal in achieving Net Zero targets due to their direct involvement in daily operations on-site. Their vigilance in managing materials, reducing over-ordering, and finding opportunities for reuse can significantly influence waste reduction efforts. By implementing strict protocols and regular audits, Ashe ensures that subcontractors are aligned with their sustainability goals, transforming them into vital partners in the journey toward Net Zero.
Could you share more details about the sustainability audit process trial at Shipston School? What were the key findings?
The sustainability audit at Shipston School was a breakthrough in understanding how materials are managed on-site. During the audit, it was discovered that a large quantity of valuable materials ended up in skips, many still in their original packaging. This prompted a reassessment of procurement strategies and material handling processes. The key takeaway was the potential for better material estimation and the importance of creating a system for reusing surplus materials, leading to both cost savings and environmental benefits.
How do you approach the issue of over-ordering materials, and what systems are in place to prevent it?
Over-ordering is a common challenge, often mitigated by rigorous procurement controls. At Ashe, a meticulous review of material requirements is conducted before project commencement. This includes leveraging data analytics to forecast material needs accurately and establishing a three-quote system for purchases to ensure cost-effectiveness and quality. These measures not only prevent excess but also support stringent budget adherence.
In what ways are construction products in skips typically reusable on other projects?
Many of the materials in skips, such as cables, pipes, and containment units, are still in excellent condition and can be directly reused. By cataloging these materials and managing an inventory, they can be allocated to new projects without the need to purchase additional supplies. This practice not only conserves resources but also reduces the environmental footprint associated with manufacturing and transporting new materials.
How did the partnership with SEC MEP help reduce waste at the Shipston School project specifically?
The collaboration with SEC MEP was instrumental in identifying and reclaiming valuable surplus materials from the Shipston School site. Their proactive approach involved conducting toolbox talks and inventory assessments to evaluate which materials could be returned or reused, drastically cutting down on waste generation. This partnership exemplified how collaborative efforts can lead to actionable waste management solutions on construction sites.
What new procedures has SEC MEP adopted as a result of the collaboration with Ashe Construction?
Following the audit, SEC MEP implemented new procedures including a comprehensive stocktake of materials returned to their stores. They introduced a procurement schedule that ensures surplus materials are integrated into ongoing projects or sent back to wholesalers when feasible. This systematic approach helps in better inventory management and sustainable resource utilization, reflecting an increased commitment to environmental stewardship.
What challenges does SEC MEP face with returning larger quantities of materials to wholesalers or manufacturers?
Returning large volumes to wholesalers and manufacturers often involves logistical challenges and acceptance criteria such as undamaged packaging. Sometimes, wholesalers impose handling fees, discouraging returns. Despite these hurdles, SEC MEP strives to navigate these procedures to secure credits and minimize waste, reflecting their resolve to overcome systemic inefficiencies.
How do product failure rates and manufacturer return policies impact waste management?
Product failure rates add a layer of complexity to waste management. When manufacturers request returns of faulty units, it offers a chance to recover costs, but often these units end up being written off. This process highlights the need for more lenient return policies that favor sustainability, allowing faulty products to be remanufactured or properly recycled rather than discarded.
Can you explain the financial controls and procurement processes that help manage surplus materials on site?
Robust financial controls involve project managers who meticulously review costs and procurement schedules to avoid over-ordering. Ashe has implemented a three-bid system to ensure competitive pricing for materials, which helps maintain tight budget controls and minimizes surplus. These processes are integral to achieving sustainable practices by aligning financial decision-making with waste management goals.
How do client-driven changes or “variations” in contracts affect waste management and surplus materials?
Client-driven variations can significantly disrupt material estimates, often resulting in surplus inventory that is difficult to return or use elsewhere. While some wholesalers may accept returns with handling fees, the financial implications often discourage such actions. To mitigate this, open communication during project planning is crucial to anticipate and manage potential adjustments efficiently.
What kind of evidence and key performance indicators (KPIs) does SEC MEP plan to provide in support of Ashe’s Road Map to Net Zero?
SEC MEP is committed to providing data-driven insights through comprehensive KPIs that track waste reduction efforts, material reuse rates, and cost savings from better inventory management. This evidential support not only highlights their collaboration but also charts a clear path toward achieving joint sustainability goals, ultimately contributing to Ashe’s broader Net Zero objectives.
Has there been any progress in influencing wholesalers and manufacturers to accept returns of unused items more easily?
While there’s still work to be done, Ashe has made strides in fostering dialogues with suppliers about flexible return policies. By emphasizing the mutual benefits of sustainability, they hope to see a gradual shift towards more accommodating practices, allowing for easier returns and credits that support waste reduction initiatives.
How does Ashe’s approach influence the way subcontractors think about waste management across other projects?
Ashe’s commitment to sustainability serves as a model for subcontractors, showcasing practical ways to integrate waste management into everyday operations. By witnessing the tangible benefits—such as cost reductions and enhanced project efficiency—subcontractors are inspired to adopt similar practices across their own projects, perpetuating positive industry-wide change.
