Hi Kavya!
What I meant with my previous comment is that, you should be able to provide a page, where there is option for the employee to create a survey.This requires full customization.
For example you may have an idea of what kind of surveys or fields your client will create (or you can get a requirement from them).
- Provide a button like create text field
- On click on it, it will ask popup to fill the text field name (like last name,first name etc) and click on ok
- Field gets created in the page (all this logic should be developed by you).
- Once all the fields are created by the employee, he can click on create survey button which will create the survey
Similarly you can do for other fields (like checkbox ,etc). Basically, the fields required in survey need to be developed by you, so employee can just select/click the fields to create a survey.
PS: This suggestion is as per my assumptions and workflow, hope it can be helpful 
Best,
Cal
