All your Questions about ESA Answered!

Summary – Have you ever wondered what does ESA means? Well, this post will try to shed some light on the matter. Read on to know more.

Before the commencement of a construction project, it is customary for the site to be teaming with experts running around and making all sorts of measurements and assessments. Now, this is a scenario that is common in construction sites all over the globe.
So what are those professionals up to?
Well, they are busy carrying out environmental site assessment or ESA. ESA is a string of processes an expert would utilize to assess –
Environmental and
The economic impact of a project.
Conducting ESA at the early stages of a project would allow one to make the necessary changes in the overall design of a project or the way the same would be completed. This is mandatory and failure to do so could land the project heads in court and the project getting cancelled altogether.
Why do it?
ESA benefits not only the environment but also the parties associated with the project.
ESA assessment allows the parties associated with a project to ensure that their project is –
Energy efficient
Promotes general wellness of the residents (in case it is residential) project or the employees (in case it is a commercial project) and
Doesn’t harm the environment in any way.
What are the different types of ESA?
ESA is of three types - phase 1, 2 and 3.
Phase 1 environmental assessment consists of the following –
Screening – Here a project will be closely examined by an ESA official. If some issue is found, the developer will be notified so that the project can be reassessed in order to minimize the environmental impact.
Scoping – here the issues that need immediate attention are identified.
Baseline study – Here all necessary information is collected, especially on the current condition of the environment around the project. This allows the officials to set up a baseline based on which further observations can be made.
Impact prediction – Here forecasting the environmental changes are shared with the developer if the project goes into the construction phase.
Impact assessment – is the stage where the impacts on the environment due to the development of the project is assessed. If the project passes this particular state then it can go into construction phases, else, the developer would need to reassess the same!
Further steps involved
Here is an overview of the basic steps of a typical phase 1 environmental assessment of a site:
Reporting in the form of Environmental Impact Statement (EIS)
Reviewing the EIS
Enforcement and
Environmental auditing.


ESA is the part and parcel of any major or minor construction project. It is the only way one can steer clear from legal troubles and penalties. On that note, it is also important to ensure that the ESA service provider has been in business for a while and comes highly recommended. This is the reason why before choosing an ESA service provider, one should do their homework by running background checks on the company and its overall abilities. One should also ensure that the company has all of its affairs in order before hiring the same.
