Performance Guidelines for Group Site Construction, Unit Installation and

Staging Area Construction

For Proposal Purposes these Performance Guidelines have been drawn from historical and trial and error experiences and may be used to calculate costs. Contractors are welcomed to propose using more stringent requirements.

Group Site Construction

Items of Work

The work requires the complete development (construction) of the Group Sites. The work includes but is not limited to: soil testing, surveying, clearing, grubbing, stripping, debris disposal, fill and grading, site utilities design and layout, fencing, installation of all necessary water, sewer, electric, gas (as appropriate), telephone distribution and facilities, cable access, roads and related installations, storm water management, and erosion prevention measures. Also provide safety fencing, signage, unit numbering, street lights, shelter lights and other items to ensure the safety of Group Site occupants as well.

Environmental Support

Support FEMA or designee work on any environmental issues. Obtain bonds and permits and begin development (construction) on time. The Contractor shall assess each potential group site for endangered species, historical concerns and check the Superfund Register. The Contractor shall coordinate with FEMA Regional Environmental Office, to be identified at the kickoff meeting.

Existing Utilities

The Contractor shall coordinate all utility relocation requirements and make payment to the utility companies for all services, fees, and permits required to relocate and re-establish service if applicable. Utility services shall not be interrupted except for brief periods to facilitate cut-ins. The Contractor shall be responsible for all costs related to protecting existing utilities. The Contractor shall coordinate construction activities with telephone and cable utilities. Coordinate utility installations with the local communications companies to include, but not be limited to, the local phone and cable companies, and not to impede completion deadlines.

Protection and Maintenance of Traffic

The Contractor shall coordinate all utility relocation requirements and make payment to the utility companies for all services, fees, and permits required to relocate and re-establish service if applicable. Utility services shall not be interrupted except for brief periods to facilitate cut-ins. The Contractor shall be responsible for all costs related to protecting existing utilities.

Surveys

The Contractor shall layout the work from the established bench marks For each feature of work, field staking shall define area limits such that the COTR can easily determine, without additional surveys, if alignment and/or limit adjustments need to be made.

As-Built

An as-built field survey of all utilities shall be conducted after installation to determine the final locations and elevations of utility manholes and hydrants. Final elevations shall be determined for all sewer inverts and castings. Three sets of drawings showing the locations of all features of the work. The as-built shall be provided to the COTR.

Temporary Construction Facilities

The Contractor shall furnish and install (1) office trailer complete for his own use with all utilities and restroom facility. The trailer will be placed at the location designated by the COTR.

Fencing

The Contractor shall provide in the design, recommendations for chain link fencing and signage for safety reasons, including, but not limited to the following areas:

Retention Pond

Substation Area

If there is an additional area of concern identified by FEMA, the Contractor shall provide chain link fencing around that perimeter.

Phasing of Construction

Phasing may be required by FEMA. In that case, all construction areas shall have a perimeter marked by orange safety fencing and adequate signage, with controlled ingress and egress. As each phase of the group site is completed and opens to applicants, the unfinished phases shall be separated from construction areas with orange safety fencing and adequate signage until all construction is completed.

A stabilization fabric or geotextile fabric will be required and this fabric shall be installed in accordance with manufactures recommendation. The Contractor is responsible to place the correct fabric based on the given soil characteristics.

Grading

During construction, the lines and grades, including crown and cross slope indicated for the base course, shall be maintained by means of line and grade stakes placed by the Contractor. Grade stakes shall be in lines parallel to the centerline of the area under construction and suitably spaced for string lining. The Contractor may use a laser system in lieu of a grade stake system. Adequate drainage shall be provided during the entire period of construction to prevent water from collecting or standing on the area to be constructed. The surface of the top layer shall be finished to grade and cross section shown. Finished surface shall be of uniform texture. Light blading during compaction may be necessary for the finished surface to conform to the lines, grades, and cross sections. Should the surface for any reason become rough, corrugated, uneven in texture, or traffic marked prior to completion, such unsatisfactory portion shall be graded.

Site grades shall be checked for low spots and depressions. All low spots and depressions shall be filled so the entire site has positive drainage. All material placed as fill or backfill shall consist of mineral soils with no vegetative matter or rocks larger than 3 inches in size. Unsuitable material shall be placed on site at a location directed by the COTR.

Compaction

All plant, equipment, and tools used in the performance of the work will be subject to approval and shall be maintained in satisfactory working condition at all times. The equipment shall meet the requirements of the referenced state standard specification sections. The base course shall be compacted using a steel-wheeled roller, vibratory smooth drum roller, or pneumatic-tired roller, unless other special compaction equipment is approved. During fill placement, each layer shall be spread uniformly in a maximum uncompacted lift thickness of 6 inches and compacted with a vibratory sheepsfoot roller until there is no further evidence of consolidation.

Finishing

The surface of the top layer shall be finished to grade and cross section shown. Finished surface shall be of uniform texture. Light blading during compaction may be necessary for the finished surface to conform to the lines, grades, and cross sections. Should the surface for any reason become rough, corrugated, uneven in texture, or traffic marked prior to completion, such unsatisfactory portion shall be graded.

All topsoil and surface material shall be removed and the sub-grade compacted prior to the placement of the filter or geotextile fabric and aggregate base. There should be no evidence of depressions from site equipment or excess rutting.

Seeding species and rates must be specified that are compatible with local climate and soil conditions.
