Need I apply design pattern for fill document data

I am using C# to create a document data.

public class Document{
      public string CreatorUsername {get;set;}
      public string CreatorDepartment {get;set;}
      public string DataFromServiceExternalService1 {get;set;}
      public string DataFromServiceExternalService2 {get;set;}
      public string DataFromServiceExternalService3 {get;set;}
      public string DataFromWebConfig {get;set;}
}

The document data properties are comes from different services, applciation username, web config like this.

I need to wait downlaod Service1, Service2, Service2, Web.config results. After all data come I will create document.

I am new at design patterns and I wonder if I apply a design pattern about this problem. For example decorator patten or else.
