Division 31 - Earthwork

31 00 00 General Information and Design Information

Existing Conditions and Design Information

This division covers the design and specifications all grading and site clearing activities associated with construction projects at Clemson University. The work specified under this division must be carefully coordinated with the work that is associated in other divisions dealing with site utilities and landscaping. The designer shall be especially cognizant of coordination issues involving soil compaction requirements that may be required for the installation of other systems and improvements. The designer shall also clearly specify that all grading activities shall comply with the tree protection requirements specified in Division 1 and in the attached “Tree Protection Policy.”

The designer shall also clearly specify the requirement for strict adherence to OSHA regulations associated with work specified under this division.

Clemson University is located in the Piedmont Physiographic Province. In general, the virgin soils encountered in this area are the residual product of chemical and environment weathering of rock similar to the remaining underlying rock.

The designer shall request any required subsurface investigation of the site in accordance with provisions of the A/E Agreement. The designer shall designate the location of any proposed soil boring locations and shall be especially aware of the locations of existing utilities. Notification to the local utility locating service and the CU Facilities Survey is also required and must be contacted for any preliminary subsurface investigation and must also be specified as a requirement for the contractor in any subsequent construction operations. The Owner will usually retain the appropriate geotechnical firm for subsurface investigation as well as testing services during construction. Consult with the Project Manager to coordinate this work.

The consulting A/E shall give special attention to insuring that all required permits are obtained from the appropriate regulating authority and that they are obtained within the prescribed time. It is the consultant’s responsibility to insure that these permits are obtained. See section on Erosion and Sediment Control (below) and Stormwater Planning and Management Policy.

31 10 00 Site Clearing

Clearing and Grubbing

Specify that debris and excess material shall not be allowed to accumulate on the site during construction.

It may be possible for clean, excess material to be deposited on campus. In such event, specify that the soil be deposited in 6” layers and machined smooth prior to depositing the next layer. Consult with the Project Manager for location to deposit this material.

Specify that existing topsoil is to be stripped from the area covered by the building, roads, walks, cuts, and fills and stockpiled on the campus at a location designated by the Project Manager.

Specify that all other waste material and debris is to be removed from the campus and deposited in a legal disposal facility or landfill. Clemson University operates a limited use C & D landfill and may be available for limited amounts of waste material. Consult with the Project Manager concerning this option and for information concerning other acceptable landfills.

Require that hazardous waste of any kind be disposed of in accordance with applicable Federal and State laws and regulations. Consult with the Project Manager on specific requirements for the disposal of hazardous wastes including asbestos containing materials.

Prohibit the burning of trash and debris and the use of explosives on campus.

31 20 00 Earth Moving

Grading

Specify the proper and adequate protection for the stability of any excavations be in accordance with applicable codes and regulations or agencies having jurisdiction.

Specify the proper quality control for excavations for footings, pavements, and trenches.

The designer is cautioned to pay special attention to compaction requirements to assure a uniform, coordinated specification in each area of fill placement and compaction. Specify compaction requirements for each particular area to comply with the appropriate ASTM density requirements.

A source of suitable fill material has become increasingly scarce on the campus. In general, the acquisition of any required additional fill material must be specified as part of the contractor’s responsibility. Consult the Project Manager for additional information.

Erosion and Sediment Control

Specify the compliance with all applicable soil and erosion control and storm runoff requirements necessary to protect the Owner’s property and facility. The size of the disturbed area on a project will determine the type of Erosion and Sediment Control and/or NPDES permits that must be obtained. The procurement of any required permits, including notifications, is the responsibility of the consultant on the project. Be aware that grading and land-disturbing activities must be performed in accordance with a specific plan designed to control erosion, retain sediment on the site, and manage storm water in such a manner that either neither on-site nor off-site damage or problem is caused or increased, and that all structural measures are designed to accepted standards for health and safety. Be sure that all provisions of the plan specified are in compliance with the Regulations contained in Chapter 72, Article 2, South Carolina Code of Regulations (Erosion and Sediment Reduction and Stormwater Management Regulations). The design must include an approved erosion control plan as required in the Manual for Planning and Execution of State Permanent Improvements.

Also see attached Stormwater Planning and Management Policy.

31 30 00 Earthwork Methods

Soil Treatment

Specify the appropriate soil treatment for the control of subterranean termites on the project site. Specify that the person applying these soil treatments must be licensed with the Clemson University Department of Pesticide Regulation.

Specify that the termiticides shall be applied at the highest label rate and strictly according to label rates and that the treatment must follow the standards for the prevention and control of wood destroying organisms prescribed by the Clemson University Department of Pesticide Regulation (Section 27-1085 of the Regulations for the enforcement of the South Carolina Pesticide Control Act).

Specify that the contractor shall notify a representative of the Pest Control Department at University Facilities at least 48 hours prior to the treatment. Inherent in this notification is the right of the Facilities staff to observe the termiticide containers being opened, seals being broken, mixing, and application. The termiticide used shall also be made available to University Facilities for testing and sampling.

Specify that a submittal be required from the contractor identifying the termiticide to be used, the rate of application, and the total quantity of material to be applied. Specify that this submittal must be approved prior to the contractor awarding this subcontract for the work. Specify that the contractor submit follow-up documentation of the actual use rate and total quantity of material applied to the site.

Specify that the final surface preparation must be done by the pest control operator prior to the treatment. This will include the removal of foreign matter and debris which would decrease the effectiveness of treatment and the loosening and raking the soil in the treated area prior to treatment.

Specify that termiticides must not be applied when the soil is excessively wet or frozen, or when rainfall is predicted as imminent.

Specify that the treatment of soil adjacent to exterior foundation walls is to be done only after all required grading, excavating, and final landscaping and filling operations are completed, except as otherwise required in construction operations.

Specify that voids in block wall construction shall be treated as practicable to the footing in order that the termiticide reaches the footing rather than being absorbed by the masonry.

Specify that rodding alone is not permitted as the primary technique of treating the soil adjacent to the foundation walls. Trenching or trenching combined with rodding is acceptable.

Specify that signs shall be posted in the areas of application to warn workers that soil termiticide treatment has been applied. Specify that some type of compatible dye be used in the termiticide to provide visual evidence of the treatment.

Specify that a quality control inspection be conducted post treatment and documentation of this inspection be submitted to the Pest Control Department at University Facilities.

Specify that the contractor is to furnish a written warranty certifying that the applied soil treatment will prevent infestation of termites, and that if termite activity is discovered during the warranty period, the contractor will re-treat the soil and repair any damage caused by termite infestation. This warranty will consist of a five year period from the date of Substantial Completion, signed by a representative of the pest control company and the general contractor. After this initial warranty period, Clemson University will have the right to assume the annual renewal with the pest control company.
