Stormwater Drainage Design

LCE Engineers have been involved in residential, commercial and industrial stormwater design, from subdivision to domestic, alterations and additions.

Liaising with the local council on your stormwater design, we coordinate to balance any specific requirements, upcoming developments encompassing your every need. Thus Resulting in quality, situation appropriate, the innovative stormwater design that is both durable, versatile and economical.

Our consulting engineers carry out the initial assessments of the stormwater design and determine whether an easement, an On-Site Detention (OSD) is required, provision of absorption trenches or whether it is a direct street connection. We guarantee to deliver you the most effective stormwater design using the latest drainage products that are currently in the market.

Erosion & Sediment Control Plan

At LCE, we help you create an Erosion and Sediment Control Plan (ESCP) to show you how to minimise soil erosion on, and sediment from, any type of construction site. This will ensure that any work undertaken on a site/land development will show how erosion and sedimentation can be controlled on and offsite.


Soil and Water Management Plan

Let us at LCE help you develop a soil and water management plan to help to detail the specific methods of erosion and sediments control that will be used to meet the specific site conditions at the various stages of construction. This plan is usually required by the council prior to issuing a construction certificate for large-scale development. 

The soil and sites management plan is important to be constructed to ensure you are reducing pollution from building sites where even the smallest amount of pollution from each site is enough to cause significant damage to our waterways.

Soil & Water Management


BASIX Certificate is one of several documents required to be submitted to a local government area council in NSW with every residential building Development Application. An online web application tool is used to issue a certificate. Also sustainability commitments and specifications addressed on the certificate must be reflected on building plans and be deployed during construction. The nominated provisions are then verified by the project's Principal Certifying Authority before an occupation certificate is issued. To get a BASIX certificate you need to introduce energy and water efficiency measures of your development to online assessment tool and get a pass score. A certificate is generated by the online tool and can be used for DA submission. The issued and submitted BASIX certificate becomes a DA document that must be referenced and referred to during all steps of construction and commissioning. The provisions must be fully deployed during construction in order for a building to be able to achieve its final Occupation Certificate.
The main types of BASIX Certificates are as below:

LCE is able to provide you with the most cost-effective and sustainable solutions for your project while achieving the mandatory BASIX requirements

NatHERS Assessment involves modeling a dwelling in a NatHERS certified thermal simulation software package, defining site conditions and finally thermal simulation of the model. In performing a NatHERS assessment certain established guidelines and protocols has to be followed in order to preserve consistency and fair comparison of different dwellings with different climate conditions and when a different computer software is used for NatHERS assessment.

NatHERS Assessment is principally based on the concept of thermal comfort of a habitable zone in a residential space. NatHERS scheme defines a zone's thermal conditions in which the occupants of that area will feel comfortable with regular clothing. Based on the climate zone of the development these conditions are slightly different. The building is modeled with a computer software package and the amount of heat that must be added or removed from each zone of the dwelling to make it comfortable for occupation is calculated. This heating and cooling loads are then represented in form of NatHERS ratings which is in form of star bands from 0 to 10 stars.


Flooding and overland flow have similar consequences in that you need to build up your land or dwellings above the flood level - but it isn’t always as easy as that. You also can’t impede flow or redirect flow in a manner that could affect other properties. Imagine if you built your property up with a retaining wall to get above the flood or overland flow levels, then the water that would usually flow over your property now hits this wall and flows elsewhere, or pools in the one location.

Flood/Overland Flow Studies

Flooding and overland flow are two distinctly different site features in terms of natural surface water runoff.  Flooding and overland flow are two distinctly different things, the only common element is they both involve water. The easiest way to look at them is that flooding is water that rises from a water source and overland flow is water that flows down to a watercourse. So keeping that in mind, overland flow can happen almost anywhere at any time. Don’t believe me? Go outside during a 5-minute downpour and take a look at the water running down your driveway.

Flood/Overlad Flow Studies


Water Quality is the hot phrase circling around all development, design, consultation and construction teams nowadays. Since more councils started to pay attention to the water quality from any kind of runoff and site residue, the quality control is put on the table with further required details and stricter control policies. 

LCE will help you with your stormwater design via Model for Urban Stormwater Improvement Conceptualisation (MUSIC) to create delegated stormwater designs like

  • Potential stormwater flows and detention from lot-scale to suburb- scale simulation harvesting and reuse estimation and downstream flows and water quality analysis

  • Pollutants modelling including suspended solids, total phosphorus and total nitrogen and estimate the impacts of various treatment options.

  • Water balance modelling

  • Water quantity, quality and cost vs benefit objectives achieved by alternative treatment- train scenarios comparison.

  • Entire stormwater systems planning. 


Civil Design

LCE has the depth and breadth of civil engineering expertise necessary to customize solutions for specific projects, irrespective of scope or size.

Our devoted teams comprise experienced professionals delivering integrated service across a wide range of disciplines including grading and drainage, street and roadway design, kerb and gutter design, footpath design, kerb returns, design of intersections and kerb ramps permitting, sustainable or low-impact design, utility coordination and more.  

We provide advice, leadership, attention to detail and the innovation you require to complete your project on time, within budget and without compromise. By tying all components together into a comprehensive civil documentation package with our top-quality documentation and project specific specifications, we are able to define clearly council and engineering requirements for every development.

Dilapidation Report

A dilapidation report details the existing condition of a building at a specific point in time. It identifies any existing damage of a structure and is usually undertaken on surrounding buildings, roads, fences etc. prior to construction works. As part of development approvals most council's will stipulate that one of these are required to protect adjoining neighbours. The report is an item-by-item account identifying the building elements and their condition and is recorded by both written and photographic evidence.

The main advantages of a dilapidation report are:

  • Satisfy the conditions for the DA approval.

  • Reduces the developers/Builders claimed damage risk by adjacent owners.

  • Records the damage of adjacent property/structure prior to construction works. This reduces the risk of claims against damage and expensive litigation on completion of works.

  • Provides the adjoining neighbours with an independent report identifying issues with their property that they may be unknown by that owner.


Dilapidation Report Services

LCE provides professional impartial dilapidation advice and reports for all types of properties and structures. Our service includes:

  • Advising the builder, developer or architect on the extent of the Dilapidation report and which structures should be inspected.

  • Onsite inspection of the building elements in accordance with the client brief.

  • Production of a written and photographic report in chronological order identifying the current building condition with photographs showing any existing damage.

  • Issuing of the report prior to works commencing.

  • A signature section within the report to be signed by all parties involved prior to any works commencing to reduce later claims and thus reduce any risk.

  • Completion inspection as required.

As well we provide 

  • Dilapidation report for council’s assets such as but not limited to kerb and gutter, footpath, power poles and other services, trees etc..


Traffic Impact Study

A Traffic Impact Assessment reviews the road hierarchy surrounding the proposed development to identify the impacts of the proposal on local street network and mitigation measures required to ameliorate any negative effects, using realistic Survey Data as well as well-known Intersection Modelling Software SIDRA.

Parking Signal System Design

In some of the development, given the site restraint and basement parking limitation, council requires a signal system to be designed and provided to manage the ingress & egress flow and the vehicle circulation.

LCE has been involved in providing such a signal operation system for parking management for different types of development. We choose the product upon the most suitable application considering cost-effectiveness and management efficiency for our client. The system is designed in a manner that the management logic follows the thinking procedure and the driving behaviour as a human being. Therefore the system is easy to be understood, able to maximise the control order and minimise the potential hazard.
