1.12 MATERIAL HAULING
A. Restrict deliveries and removal of bulk materials, supplies, waste soils and equipment to and
from the Project site to The Authority-designated roads and haul routes indicated on the
Drawings.
B. Access and egress to and from the Airport for hauling operations shall be through the entrances
indicated. Conduct hauling operations in accordance with the Contract documents. Access to
and from the site may be performed on a 24/7 basis, subject to restrictions imposed by other
requirements of the Contract Documents and as acceptable to The Authority.
C. The designated haul routes for hauling operations may require vehicles crossing existing taxi
lanes or taxiways. Under no conditions shall the Contractor plan use of taxiways and taxi lanes
for hauling equipment. Haul routes for this project are as indicated.
D. Schedule, phase, and sequence work operations to minimize the number and duration of
roadway closures. Coordinate with the COTR and submit a detailed Work Plan for Contractor’s
entire operations to the COTR for approval prior to commencing work. Obtain written approval
from the COTR of the Work Plan. Identify clearly on Work Plan each operation requiring
coordination with Airport Operations.
1. For roadway closures of short duration, provide flagmen. COTR will determine the
number of flagmen required.
2. For long-term roadway closures, clearly mark, light, and barricade the roadway closures
and haul routes in accordance with Airport Operations requirements.
E. Notify the COTR at least 72 hours in advance of his requirement for scheduled roadway
closures. Obtain the written approval of The Authority prior to closing or crossing a roadway.
F. Bear all costs associated with establishing, maintaining, signing, lighting and marking haul
routes. These costs are considered incidental to the pay items of this Contract.
G. Use load covers on all dump trucks. Load dump trucks so that no spillage occurs during transit
on the State, municipal, or Airport roadways and pavements. Clean wheels of trucks leaving the
Project construction site of all soil and rocks. Provide a truck washing rack on the Project site
to minimize the tracking of soil onto paved surfaces.
H. Be responsible for the cost of the immediate cleaning of earth tracking and spills on paved
surfaces resulting from the Contractor's operations. Because of the potential for extreme damage
to aircraft engines due to the ingestion of foreign objects, maintain on the project mechanical
sweeper/vacuum (wet/dry) equipment with nylon brushes complete with operators. Maintain a
water truck on site as required in order to effectively control dust rising from construction
activities.
I. Provide sweeper/vacuum equipment with a usable hopper capacity of 6 cubic yards and with a
regenerative air capacity of 15,000 CFM. Provide equipment with gutter brooms of poly brush
material so as not to damage airfield pavement markings; a dust control system that includes an
external spray system with front mounted spray bar, nozzles located at each gutter broom; and
an internal spray system with nozzles in the internal air stream. Maintain the equipment in good
