Key Challenges That Sydney Water Accredited Contractors Face When Constructing Sewers

Summary – Sewer construction is a complicated process. Here are the main challenges Sydney water accredited contractors face in these projects. 

Even for the most experienced Sydney water accredited contractors, constructing or modifying sewers is a challenging process. That’s because dealing with water or wastewater-related projects is never easy. These environmentally conscious engineers have to divide these projects into multiple stages such as - 

• Pre-planning to discuss what the issues are with the existing sewer.

• Creating preliminary designs after assessing the property. 

• Creating final designs after multiple corrections.

• Attaining the permits required to construct or modify the sewers.

• Preparing construction documents.

A top Sydney water-accredited constructor will have to collaborate effectively with property owners, sewer designers, sewer engineers, and government regulators during these construction processes. Since so many people and so many variables are involved in these projects, the risk of mistakes is ever-present. 

Here are the key challenges that Sydney water-accredited contractors face when constructing sewers. Hopefully, by learning about these common mistakes, property owners and their contractors can avoid them in future projects involving water and wastewater –

Unsuitable Subsurface 

For any Sydney water accredited constructor, excavation is a key part of the job. That’s why in complicated infrastructure projects, all conditions need to be perfect, especially the sub-surfaces. Or else, installing pipelines, underground tanks, or sewer systems is difficult as performing excavation activities on unstable sub-surfaces is nearly impossible. 

• Constructors must conduct foundation investigation reports to discover rock cores, logs, etc., that may be present in the subsurface.

• They must assess topographical maps and compare them with the subsurface data they gain during investigations to gain a detailed understanding of the underground conditions. Based on these assessments, they can modify their excavation-related requirements.

• Detect unaccounted structures or rocks in the subsurface so that they don’t negatively impact project dynamics. 

Discovering that you’re working on an unstable and unsuitable subsurface in the middle of the project can lead to unnecessary construction delays, amplified project costs, and various other on-site difficulties. That’s why prior investigations and assessments of the sub-surfaces are vital in sewer construction projects. 

Planning Challenges 

All Sydney water accredited contractors are masters of planning. They sequence different stages of the sewer construction process during the design phase. However, these pre-determined construction sequences are not always perfect. There are many challenges that may pop up during the sewer construction process.

Since these contractors often have to make upgrades or additions to sewer systems within pre-existing premises, maintaining a fixed plan is always tricky. That’s why well-seasoned sewer construction experts are always flexible. They can adapt to complex on-site challenges in ways that don’t hamper the overall sewer construction process. 

Errors in Construction Documents

While constructing sewers, contractors have to deal with various drawings, specifications, and construction documents. They have to create - 

• Site drawings

• Electronic reports about the old sewer systems.

• Detailed field surveys covering important topics like ground quality, whether the project involves pipes or valves, etc.

• Vendor information

• Site plans

• Layouts

• Equipment requirement reports

Small discrepancies in these documents can eventually affect project quality. That’s why property owners must only work with experienced sewer construction specialists who know how to minimise ambiguities in contract documents.
