Metro Parking Garage No. 2
Owings Mills, MD
Under an On-Call contract with the Maryland Transit Administration (MTA) for construction management and inspection services. Environ-Civil Engineering, Ltd. (ECE) was tasked to provide engineering cost for the Metro Parking Garage No. 2 in Owings Mills, Maryland.
The cost estimate was taken off from the drawings provided to ECE by MTA. The drawings are architectural, structural, mechanical and electrical. ECE made the assumption that the drawings used are 100% complete as stated in the task order. The cost estimate consisted of sixteen (16) C.S.I. sections ̶ 1) General Requirements, 2) Site Work, 3) Concrete Work, 4) Masonry Work, 5) Metals, 6) Wood and Plastics, 7) Thermal and Moisture Protection, 8) Doors and Windows, 9) Finishes, 10) Specialties, 11) Equipment, 12) Furnishings, 13) Special Construction, 14) Conveying Systems, 15) Mechanical Systems, and 16) Electrical systems.
The site drawing and traffic control drawings were not provided; therefore, the cost associated with them was not included in the estimate provided. No specification for the project was provided by MTA, therefore, the general requirement for Division 1 was assumed at 8.5% of the subcontractor cost. To estimate the total cost for each division, a 10% GC markup was added to the estimated subcontractor cost.
For the estimated cost, the following were added to the Subtotal a ten percent (10%) design contingency, ten percent (10%) construction contingency and yearly escalation of 3.8%.
Spill Prevention Control and Countermeasures Plan (SPCCP)
Environ-Civil Engineering, Ltd. (ECE) performed spill prevention control and countermeasures study to assist Maryland Transportation Authority to ensure that oil does not get to the waters of United States at its facilities. The facilities are: JFK Maintenance I, JFK Weigh and Inspection Station, Francis Scott Key Bridge Maintenance, Fort McHenry Tunnel Maintenance, and Harry W. Nice Bridge Maintenance. ECE personnel conducted site visits to study the physical condition of facilities, observe oil storage areas, spill containment structures, existing conditions, storm sewer locations and associated outfalls, storage tank operations and housekeeping practices. A spill prevention control and countermeasures plan was prepared at the conclusion of our study. The plan outlines a comprehensive spill prevention program to minimize the potential for oil discharge from facilities.
