Profecl:Task Order frll - 2022 HangarTaxilane Development
ProjectNo.: 12436
Scope of Servlces:
Oven iew
The Client has solicited from Century West Engineering services for design development of a new taxilane that is to b€
located south of the mid-fleld County owned T-hangars and west of the terminal building.
This project scope provides development of layout alternatives and cost analysis, preparations of bid documents of the
selected alternative, and biddinB support.
The prime consultant is Century West Engineering. (PG is a subconsultant to Century West Engineering, and will provide
survey services. HWA is a subconsultant to Century West Engineering, and will provide geotechnical assessrnent
services.
The activities and work elements fqr each task are described as follows.
TASK 1- Administratlon
Administrative tasks will include the following,
1.1 Project setup, administration, invoicing and coordination,
