The Milestone Reservoir Project, a key element of Loudoun Water’s Potomac Water Supply Program, is transforming a retired Luck Stone quarry into a billion-gallon raw water storage reservoir. 💧✨ Once completed, this innovative project will strengthen regional water security and enhance climate resilience for Loudoun County, Virginia. 🌍🔧 #WaterEngineering #Sustainability #ClimateResilience #Innovation

🌟 **Project Update: Successful Implementation of Artificial Groundwater Recharge** 🌟 We are excited to share the development we made 2 year ago, in our 5-storey commercial project. To safeguard our substructure from unwanted underground water pressure, we had successfully drilled four boreholes as part of our artificial groundwater recharge system. 🔧 **Project Details:** - **Objective:** To prevent groundwater from reaching the basement floor surface and exerting pressure on the substructure. - **Solution:** Drilled four strategically placed boreholes equipped with porous linings to facilitate efficient water seepage back into the deep ground. - **Outcome:** Enhanced groundwater management, ensuring structural integrity and long-term durability of our commercial building. By implementing this technique, we not only protected our infrastructure but also contributed to sustainable groundwater management. #Construction #Engineering #GroundwaterRecharge #SustainableBuilding #ProjectManagement ---

Working on contaminated sites We have the expert contacts and experience to evaluate ground conditions and make recommendations that will add value to a project. Geotechnical research that deals with contamination is most useful on larger housing estates and residential developments. Accurate volumetric calculations are an intrinsic part of calculating cut and fill requirements, good stockpile management and many other elements of the construction process. Working with specialist partners, we can determine how much soil needs to be removed, or moved, to get the levels right, enabling improved cost management of earthworks and possibly allowing the use of areas of a site that had been previously considered unviable.

Geotechnical reports are used to obtain information and data when proposing a plan for a new structure, or attempting to repair one that has fallen into disrepair due to subsurface conditions. Geotechnical reports coincide with site investigations and also delve into the construction capacity of soil or fill materials MKC INFRASTRUCTURE LIMITED #mkc #work #sitework

Soil improvement encompasses various techniques aimed at enhancing soil properties to make it suitable for construction, infrastructure, and geotechnical projects.

Water ingress into tunnels is a common challenge during construction, particularly in areas with high groundwater levels. Water entering the tunnel can compromise structural integrity, cause delays, and increase costs. Several methods can be used to control water, but pre-excavation grouting is among the most effective. This technique requires thorough ground investigation prior to construction and probing ahead of the tunnel face during excavation to identify water sources. The ground is then treated with an appropriate grouting technique before the excavation of that area. If pre-excavation grouting is not possible or proves unsuccessful, other methods can be employed during construction, depending on the geological and hydrogeological conditions. Post-excavation grouting is a common alternative but can take longer to stop water ingress. It often requires a specially designed grout mix tailored to the ground conditions and water flow. Multiple attempts may be necessary, as water can stop in one location but reappear elsewhere in the tunnel. Dewatering is another method to reduce groundwater levels around the tunnel, effective in certain conditions, particularly soft ground with high groundwater levels. However, this approach may have environmental impacts, which can be mitigated through careful planning and management.

🚧 Lets understand the fine lines between Real-Time Probing and Pre-construction investigation ❗ The Key to Water Ingress Prevention in Tunnels.👇 Share your views ▶️ While pre-construction investigations, including geophysical test methods, can provide only a general idea for planning, estimations, tendering and design, they fall short in preventing water ingress, as this is a factor of specific joint gaps opening up at the tunnel crown, walls or invert and alignment driven. ▶️ Therefore, there is no substitute for real-time probing, face mapping, and 3D logging and it's scientific interpretation during tunnel excavation to identify where ground treatment by grouting is needed. ▶️ Based on probe hole observations, cement grouting before blasting is a much easier and safer way to prevent water ingress in tunnels than attempting it afterward. It is more advantageous to know specific vulnerable locations rather than having a general understanding.

This NZGS survey is trying to get a feel for our industry's understanding and experience with tiered walls - it's real short and easy to complete, so please do! Tiered walls are challenge for sure - but in my experience most structural engineers and geotechnical engineers know how to design for the situation. The real issue are the pelthora of undesigned tiered walls being built to avoid the need for building consent. Although we, as design professionals, know that they still need consent, the general public think they can build two 1.4m high walls without consent.
