On behalf of the City of Burlington and Pinnix Road Dev, LLC, please find enclosed for your review and
approval the following:
1. Original and one (1) copy of Fast Track Application with required certification.
2. Application Fee in the amount of $480.00.
3. Specifications for the Project (2 copies).
4. Color USGS map showing project and surrounding areas (2 copies).
5. Street Level Map (2 copies).
6. Flow Tracking Form FTSE-10/18 (2 copies).
Pinnix Road Dev, LLC is developing Pinnix Road Subdivision in Burlington, NC. This project consists
development of 26 single family homes and 1,274! linear feet of 8" public gravity sewer. This is the
project I emailed you about a couple of weeks ago regarding the need for a variance; however, Mr.
Charlie Miller has advised a variance is not required since we are using DIP pipe and that request can be
made using the fast track method. We are proposing to install a cradle to support the storm sewer pipe
as required by the City of Burlington and have provided specifications to address this issue. Requested
flow allocation is 9,360 GPD. Sewer from this project will tie into an existing City of Burlington 8" sewer
main and will then flow to the East Burlington Wastewater Treatment Plant (NC0023868).
Should you have any questions or need any additional information, please feel free to contact me.
With Best Regards,
Alley, Williams, Carmen and King, Inc.

a. A permeability rating of 0.00 when tested according to Method A of ASTM E-96-66 Procedure A
with a test duration of 30 days.
b. The following test must be run on coupons from the factory lined ductile iron pipe:
1. 1. ASTM B-117 Salt Spray (scribed panel) - Results to equal 0.0 undercutting after one year.
2. ASTM G-95 Cathodic Disbondment 1.5 volts @ 77 o F. Results to equal no more than 0.5
undercutting after 30 days.
PROJECT SPECIAL PROVISIONS PSP-I

Pinnix Road Subdivision
Burlington, North Carolina 21045
3. Immersion Testing rated using ASTM D-714-87.
i. 20% Sulfuric Acid - No effect after one year.
ii. 25% Sodium Hydroxide - No effect after one year.
iii. 160 ° Distilled Water - No effect after one year.
iv. 120 ° Tap Water (scribed panel) - 0.0 undercutting after one year with no effect.
The lining shall be applied by a competent firm with a successful history of applying linings to the interior
of Ductile Iron pipe and fittings.
Prior to abrasive blasting, the entire area to receive the proactive compound shall be inspected for oil,
grease, etc. Any areas where oil, grease, or any substance that can be removed by solvent is present shall
be solvent cleaned using the guidelines outlined in DIPRA-1 Solvent Cleaning. After the surface has been
made free of oil, grease or other substances, all areas to receive the protective compounds shall be
abrasive blasted using compressed air nozzles with sand or grit abrasive media. The entire surface to be
lined shall be struck with the blast media so that all rust, loose oxides, etc., are removed from the surface.
Only slight stains and tightly adhering annealing oxide may be left on the surface. Any area where rust
reappears before lining must be reblasted.
After the surface preparation and within 8 hours of surface preparation, the pipe interior shall receive 40
mils nominal dry film thickness of Protecto 401. No lining shall take place when the substrate or ambient
temperature is below 40 degrees Fahrenheit. The surface also must be dry and 5 dust free. If flange pipe
or fittings are included in the project the lining shall not be used on the face of the flange.
Due to the tolerances involved, the gasket area and spigot end up to 6 inches back from the end of the
spigot end must be coated with 6 mils nominal, 10 mils maximum Protecto Joint Compound. The Joint
Compound shall be applied by brush to ensure coverage. Care should be taken that the Joint Compound
is smooth without excess buildup in the gasket seat or on the spigot ends. Coating of the gasket seat and
spigot ends shall be done after the application of the lining.
The number of coats of lining material applied shall be as recommended by the lining manufacturer.
However, in no case shall this material be applied above the dry thickness per coat recommended by the
lining manufacturer in printed literature. The maximum or minimum time between coats shall be that time
recommended by the lining material manufacturer. No material shall be used for lining which is not
indefinitely recoatable with itself without roughening of the surface.
Protecto 401 Joint Compound shall be used for touch-up or repair in accordance with manufacturer's
recommendations.
Inspection:
1. All Ductile Iron pipe and fittings shall be checked for thickness using a magnetic film thickness
gauge. The thickness testing shall be done using the method outlined in SSPC-PA-2 Film
Thickness Rating.
2. The interior lining of all pipe and fittings shall be tested for pinholes with a nondestructive
2,500-volt test. Any defects found shall be repaired prior to shipment.
3. Each pipe joint and fitting shall be marked with the date of application of the lining system
along with its numerical sequence of application on that date and records maintained by the
applicator of his work.

existing utilities or structures during excavation of construction or for measures necessary to negotiate
crossings of existing utilities or structures.
In cases where an existing utility follows a parallel path in close proximity to the utility under
construction, and it is not practicable to remove theexisting utility or redesign the utility under
construction, the Engineer may order special methods to be employed and allow extra compensation for
such measures as are required.
B. Excavation and Preparation of Trench
Trench excavation shall be carried out in such a manner as to conform to the line and depth of cover
shown on the plans, excavation shall proceed in advance of pipe laying at least fifty (50') feet, but only so
far as the Engineer will permit. The trench shall be so braced and drained that workmen may work
therein safely and efficiently. It is essential that discharge from pumps be led to natural drainage
channels, to drains, or to storm sewers.
Trench width may vary with the depth of trench and nature of the excavated material, but in any case
shall be of ample width to permit the pipe to be laid and jointed properly and the backfill to be placed
and compacted properly. The minimum width of unsheeted trench shall be twenty (20") inches, but in
no case shall the width be less than twelve (12") inches greater than the nominal diameter of the pipe.
PROJECT SPECIAL PROVISIONS PSP-3

Pinnix Road Subdivision
Burlington, North Carolina 21045
Pipe foundation shall at all times be such that the pipe rests uniformly along its entire barrel length on
the trench bottom. Bell holes shall be dug, and no pipe will be accepted where the bells of the pipe are
supporting the weight of the pipe. Any part of the trench excavated below grade shall be corrected with
approved compacted material before the pipe is laid. Where the subgrade is unstable or water is present
in quantities sufficient to make uniform earth bedding of the pipe impossible, the contractor shall
stabilize the trench bottom with #5 or #57 stone. The contractor shall keep all trenches free from water
during the excavation for and laying of the utility lines.
Pipe clearance in rock shall be a minimum of six (6") inches below the grade line of the pipe and nine
(9") inches clearance on each side of the nominal diameter of the pipe shall be provided. Should rock be
encountered in trenches, the trenches will be brought back to grade with crushed stone and properly
compacted.
Piling of excavated material shall be done in such a manner that danger to the work and inconvenience
to the public is kept to a minimum. Street drainage shall be maintained by suitable means.
The contractor shall remove by pumping any water, which may accumulate in the trenches and other
excavations under this contract and shall build all dams and do all other work necessary to keep the
trenches or other excavation free from water. The Contractor shall at all time have sufficient pumping
machinery ready for immediate use. All surface water shall be prevented from entering the open ditches
or excavations by proper grading of the ground surface in the vicinity of the excavation.
C. Rock Excavation
Any material shall be considered rock that in the opinion of the Engineer cannot be excavated except by
drilling and blasting or drilling and wedging. Any materials, which can be removed by means other than
those above specified, but which for reasons of economy, the contractor prefers to remove by drilling
and wedging, will not be classified as rock.
No soft or disintegrated rock, which can be removed with a pick, nor any material which can be broken
down by sledge hammer, nor ledge or boulders less than 1/2 cubic yard in volume, nor loose, shaken or
previously blasted rock, nor broken stone in rock fillings or elsewhere will be considered as rock
excavation.
All blasting operations shall be conducted in a safe and satisfactory manner. Any rock excavation within
five (5') feet of underground utilities shall be done with a very light charge of explosives and the utmost
care shall be used to avoid disturbing the existing utility. All exposed pipe lines and other structures shall
be carefully protected from the effects of blasts and any damage done to them by blasting shall be
properly repaired by the contractor, at his own expense. Sufficient warning shall be given to all persons
in the vicinity of the work before blasting. The site of the blast shall be covered with blasting mats or
other devices to prevent damage from flying rock. The time of blasting and the number and size of
charges must be satisfactory to the Engineer. Blasting shall be performed by experienced persons.
Where blasting takes place within one thousand (1,000') feet of a utility, structure or property which
could be damaged by vibration, concussion, or falling rock, the contractor shall be required to keep a
blasting log containing the following information for each and every shot:
(1) Date of shot (2) Time of shot (3) Foreman's name (4) Number and depth of holes (provide
sketch) (5) Approximate depth of overburden (6) Amount and type of explosive used in each
PROJECT SPECIAL PROVISIONS PSP-4

Pinnix Road Subdivision
Burlington, North Carolina 21045
hole (7) Type of caps used (instant or number of delays) (8) Weather Conditions including
temperature and humidity (9) Station number or reference to the construction base line survey
data (10) Manufacturer and type of explosive
This blasting log shall be made available to the Engineer upon request and shall be kept in an orderly
manner. Compliance of the contractor with these specifications does in no way relieve him of legal
liabilities relative to blasting operation. All blasting operations will be conducted in strict accordance
with existing ordinances and accepted safe practices relative to the storage and use of explosives.
Where blasting takes place within five hundred (500') feet of a structure, the contractor:
1. Shall employ the services of an independent qualified blasting consultant to inspect the blast site
and provide sufficient written and photographic documentation to accurately reflect the pre -blast
condition of the structure.
2. Provide vibration -recording instruments to record peak particle velocity (2.0 inches per second
maximum allowable) and frequency (15 hertz minimum allowable).
3. Provide post blast inspection upon completion of the project.
D. Backfilling Trenches
Backfill material shall be ofgood quality and free of cinders, frozen material, ashes, refuse, boulders,
rocks or organic material. Rock and boulders shall be excluded from backfill for at least two (2') feet
above the top of the pipe, and no stone larger than eight (8") inches in its largest dimension shall be
used in backfilling.
Backfilling along the sides of the pipe and immediately above the pipe will be done with extreme care to
assure that backfill material is distributed properly and to proper grade and alignment. Backfill material
will be placed and compacted in six (6") inch layers or as directed by the Engineer.
All trench backfill under paved areas (or proposed paved areas), parking areas, sidewalks, and shoulders
shall be compacted to a density of ninety-five (95%) of maximum dry density as determined by AASHTO
Method T-99. Cross-country water lines shall have backfill compaction of ninety (90%) percent of
maximum dry density unless otherwise directed by the Engineer. Dry material used in refilling will be
sufficiently moistened, as directed by the Engineer, so that moisture content will be within five (5%)
percent of optimum and future settlement will be at a minimum.
It shall be the contractor's responsibility to maintain all pavement cuts until paved or accepted by the
owner.
No water tamping of backfill will be allowed. Under no circumstances shall pipe be allowed to be laid in
water. The contractor shall not have open in excess of two hundred (200') feet of water and/or sewer
main trench at one time. Backfilling shall be completed at the end of each day's work.
E. Trench and Excavation Safety
The contractor shall at no extra cost to the City follow guidelines set up by the Occupational Safety and
Health Administration (OSHA) of the U.S. Department of Labor for safe trenching and excavation work.
All trenching over five (5') feet deep will be sloped, shored, sheeted, braced and otherwise supported.
When soil conditions are unstable, excavations shallower than five (5') feet also must be sloped,
PROJECT SPECIAL PROVISIONS PSP-5

Pinnix Road Subdivision
Burlington, North Carolina 21045
supported or shored. The type of OSHA construction safety standard used is optional to the contractor.
Shoring or sheeting below the top of the pipe should be left cut off above the pipe.
INSTALLATION OF SANITARY SEWER PIPE
All materials for laying and jointing the pipe in the trench will conform to the specifications for such
material herein given and will be furnished by the contractor. Grade lines for aligning and grading the
pipe in the trench will be established by the Engineer, and all labor and materials required will be
furnished by the Contractor. Pipe laying in general will conform to ASTM C-12.
Prior to being lowered into the trench, each pipe will be inspected by the crew foreman. Faulty pipe shall
be rejected and removed from the work site.
No pipe will be laid in the trench until the Engineer has been notified of the intention of the contractor
to lay pipe, giving the Engineer sufficient time to check the lines and grades before pipe laying is begun.
The Engineer may order the removal of and relaying of any pipe laid without such notice having been
given and without direction from the Engineer to proceed having been received.
No pipe will be stockpiled or temporarily laid out within ten (10) feet of excavation in earth or within
thirty (30') feet of rock that must be blasted for removal. The open end of all pipes will be plugged when
pipe laying is not in progress, and all pipe will be protected against injury from falling rock when blasting.
Pipes having any defects which are insufficient to cause the rejection of the pipe will be laid so as to
bring defects in the top half of the sewer, observing such special directions as the Engineer may give with
reference thereto.
Pipe will be laid uphill with the bell of the uphill end of the pipe. A bell hole will be dug for each bell, but
only of sufficient size to insure that the pipe will bear evenly throughout its length on the bottom of the
trench.
Unless rock is encountered, all vitrified clay pipe shall be laid in accordance with class "B" or class "C"
bedding requirements. See drawing detail SS-1. All vitrified clay pipe laid shall have #5 or #57 stone
placed beneath the pipe a minimum of four (4") inches or one -eighth of the outside diameter of the
pipe, whichever is greater. (See TRENCH EXCAVATION AND BACKFILLING, paragraph B. Excavation and
Preparation of Trench.)
The pipe and fittings will be laid in the trench so that after the sewer is completed the invert of the pipe
will conform accurately to the line and grade given by the Engineer. A laser beam shall be used to obtain
horizontal and vertical alignment.
Whenever the Engineer's drawings show, or for other reasons it may be necessary to change from
ductile iron pipe to vitrified clay pipe, or visa versa) the Contractor will furnish a donut 30 manufactured
by Fernco Joint Sealer Company, or approved equal, or a flexible coupling with two stainless steel
clamps, manufactured by Fernco, or approved equal, to make the joint. A brick and mortar collar will be
constructed around all joints where couplings or donuts are used.
PROJECT SPECIAL PROVISIONS PSP-6

Pinnix Road Subdivision
Burlington, North Carolina 21045
In trenches of excessive depth, concrete encasement may be required. Class C concrete will be placed
around the pipe as indicated on the drawings. In severe soil conditions requiring unusual treatment, the
actual amount of concrete placed around the pipe will be determined by the Engineer.
Whenever the Contractor, through carelessness or otherwise, has excavated trenches of widths or
depths not in accordance with the specifications, the extra amount of concrete or other material
required to properly bed the pipe and secure the results above specified will be placed by the Contractor
at his own expense.
Concrete placed in trenches that require sheathing will be permitted to set not less than three (3) days
before sheathing is removed. Backfilling of trenches, whether the pipe is bedded in concrete or not, will
be carefully done with selected material thoroughly tamped to a point above the top of the pipe as
specified under "Trench Excavation and Backfilling".
Upon completion of the entire work, all lines will present a clean and unbroken barrel. All lines will be
thoroughly cleaned and inspected by the Contractor before asking for final inspection by the Engineer.
Any defective lines will be repaired and any deposits removed by the contractor, at his own expense. Any
materials left along the line of the trench after work on the sewer is completed will be removed by the
contractor, and if not owned by the contractor, stored as directed by the Engineer.
CRADLE INSTALLATIONS
Contractor shall excavate a minimum of 4-inhces below bottom of 8" DIP sewer main for stone bedding
and place stone bedding to line and grade of proposed sewer main. Stone bedding shall extend from MH
No. 7 to 10-ft beyond 18" DIP Storm sewer pipe.
Install 8" DIP sanitary sewer line to proposed grade. Install filter fabric over 8" DIP to prevent flowable fill
adhering to the pipe.
Install 18" DIP storm sewer pipe to proposed line and grade installing a joint over center of 8" DIP. Place
flowable fill under 18: DIP to at least mid -point of 18" DIP. Confirm that 18" DIP does not move during
placement of flowable fill. Backfill trench after flowable fill has sufficiently cured.
