Trees, other vegetation, stumps, roots and brush in areas to be cleared shall be cut off fifteen (15) centimeters above the original ground surface or as close to the ground as practical under snow conditions. The use of fellerbunchers for clearing will be acceptable. However, a final inspection of the road will not be carried out until all bunched timber has been processed at roadside.
4. SALVAGE OF CLEARED MATERIAL
All timber shall be salvaged as stated in the Contractor's Cutting Permit (and associated regulations) and will become the property of the Contractor. The Contractor may arrange to pile the timber along the edge of the roadway right-of-way in a suitable manner so as not to interfere with roadway construction. The Contractor must then ensure the removal of the timber within the time frame specified in the cutting permit or it will be forfeited by the Owner to the Crown. All timber must be disposed of, as stated in the Forestry Act or Regulations.
4-2
5. PAYMENT
Payment will be made at the Contract unit price per hectare for the total length of land that has been cleared by the Contractor based on the width of right-of-way specified in "Construction Specifications", Page 5-1
In cases where Construction Specifications stipulate that certain sections along the right-of-way are to be cleared to widths other than the aforementioned; payment will be based on the unit price per hectare multiplied by the area cleared along that section.
6. BRUSH MATS/CORDUROY
The Contractor may encounter instances where either the use of brush mats or corduroy are called for in the Contract or is identified in the field by the Engineer or Inspector. In constructing a brush mat or corduroy the Contractor should first use submerchantable or non-merchantable stems. In the event that these are not present or sufficient; permission must be obtained from the Engineer or Inspector prior to merchantable stems being utilized. Stems are to be placed in a “butt to top” alternating fashion for the entire length of the area to be brush matted. Upon completion of subgrade, the Contractor must trim all excess brush mat and leave the shoulder of the road in a neat and tidy fashion.
(Rev. 05-02-17) 4-3
STRIPPING(SECTION 2)
1. DESCRIPTION
Under this item the Contractor will perform all operations in connection with stripping cleared areas along the uncompleted length of the route.
2. GENERAL
Area to be stripped shall consist of all excavations and embankments less than one (1) meter high and all ditches. Embankments greater than one (1) meter shall not be stripped and brush, rotten wood and other refuse from clearing may be used as a mat or used as fill in areas requiring deep fill provided it is well packed and covered with at least one (1) meter of acceptable granular fill.
3. STRIPPING
Stripping shall consist of the removal and disposal of all stumps, roots larger than four (4) centimeter diameter, matted roots, moss, bog, surface boulders, and any other vegetation or debris. Stripped material not used in the construction of the road bed shall be pushed to the edge of the right-of-way and left in a neat and tidy fashion so as not to obstruct access to adjacent forest land.

CULVERTS(SECTION 3)
1. DESCRIPTION
This work shall consist of supplying and placing metal or HDP pipes, jointing material and couplers in accordance with the plans and specifications.
2. MATERIALS
Corrugated metal pipe (CMP) 600 mm or less in diameter, shall be 1.6 mm thickness or heavier metal. CMP’s greater than 600 mm up to 1,000 mm shall have a thickness of 2.0 mm or heavier metal. CMP’s greater than 1,000 mm shall not have a thickness less than 2.8 mm. CMP’s greater than 1,400 mm must have a corrugation profile of 76 mm x 25 mm. Unless otherwise stated, High Density Polyethylene Culverts (HDP Culvert’s) will be an acceptable substitute to CMP’s. These culverts must be constructed of high density polyethylene with 210 kPa stiffness, be double walled, hollow inside and applicable for Forestry application.
3. CULVERT PLACEMENT
The Contractor shall shape the trench to conform to the bottom of the culvert and shall provide a uniformly firm bed throughout the entire length. Where an unsuitable soil is encountered at the bottom of the trench, suitable material shall be substituted and compacted to the satisfaction of the Engineer. Proper equipment or sufficient personnel are to be provided for lowering the culvert into the trench. After culvert joints and alignment have been inspected, the culvert shall be backfilled with select granular material to a point not less than sixty (60) centimeters above the top of the culvert. This backfill material shall be deposited equally on both sides of the culvert in layers and thoroughly compacted. If the road depth is such that the culvert cannot be placed sixty (60) centimeters into the roadbed, the road must be built up to this height. It will be necessary to backslope twenty-five (25) meters on both side of such culvert.
4. EMBEDDING & IN THE DRY INSTALLATION
All culvert bottoms in fish bearing streams are to be placed below the natural streambed level according to the following criteria: for culverts less than 750mm outside diameter, one-third the diameter of the pipe should be below the streambed; for culverts greater than 750mm outside diameter, a minimum of 300mm below the streambed. The only exception to this would be when bedrock is encountered and it is impossible to embed the culvert. Such situations must be identified to the resource road inspector prior to culvert placement.
Culverts that are to be installed on fish bearing streams must be installed “In-the Dry”. Refer to Appendix I for culvert installation techniques.
4-5 5. BLOCKING
All culverts 900mm and greater are to be blocked during installation so as to avoid failure. The contractor is to place rough lumber along the top and bottom of the culvert and blocks in between to provide support during backfilling of the culvert. Once properly placed backfill material has reached 3/4 of the height of the culvert, this blocking is to be removed to allow for proper culvert settlement.
The Contractor will be required to use a mechanical tamper to ensure proper installation of all culverts 900mm or greater. Backfill should be spread and compacted in 150mm (6") lifts alternating from one side of the culvert to the other and should extend above the culvert to the minimum height of cover specified in the "Construction Specifications", and if not specified there, as stated under this section. If the proper installation method is not utilized, the Contractor will be responsible for all costs associated with culvert failure.
6. EMBANKMENT SLOPE AND COMPACTION
The contractor must ensure that the road embankment slope is at 1.5:1 (as per Drawing No.3) for a minimum of 10 m on all sides of culverts. The immediate area around culvert inlet and outlet is to be compacted (with bucket) prior to placement of riprap or armour stone.
7. RIPRAP
Riprap shall be laid at the upstream and downstream end of all culverts. The Contractor shall utilize stones with an average diameter between 20-30 centimetres as riprap. The Contractor shall place by hand, larger stones at the bottom and take care to place the stones as close together as possible. The minimum requirements for riprap are shown below.
4-6
8. SITE REHABILITATION
The Contractor shall supply and spread grass seed on all sides of culverts 900 mm and greater to mitigate the possible negative effects of silt entering the stream. This will be done to the satisfaction of the Resource Roads Engineer or Inspector. Excessive disturbance to the stream banks may, at the Engineer's discretion, require the placement of filter fabrics or hay to lessen effects of siltation. All culverts less than 900mm will be subject to these remedial measures if it is determined by the Engineer that such action is necessary to alleviate environmental problems.
9. PAYMENT
Payment for the supply, transportation, installation, backfilling, riprapping and site rehabilitation shall be made at the unit price quoted for all culverts. This shall include any extra culverts that may be required to complete said job.
(Rev. 05-02-17)) 4-7
ROADWAY EXCAVATION AND GRADING(SECTION 4)
1. DESCRIPTION
This work shall consist of excavating materials as required to construct the roadway to a minimum top width and with such materials as to permit loaded trucks to travel at normal speeds as indicated in the "Construction Specifications".
Grading shall consist of the hauling, levelling, shaping, ripping of cuts, filling of embankments, trimming of side slopes and the construction of ditches.
2. EXCAVATING EARTH
Earth shall be excavated as required to complete earth cuts, ditching, sub-excavation and shall include hauling handling and disposal as directed.
The Contractor may, with the approval of the Engineer or Inspector, excavate outside the limits of the roadway for the purpose of obtaining suitable and/or sufficient material to complete embankments. All holes/pits are to be filled in with grubbing material.
All earth cuts shall be finished to true cross sections as excavations progress.
The Contractor is responsible for constructing the road to the grades indicated on the road profile. These grades shall govern. Volume of cuts and fills indicated on the profile are based on overburden estimates and are only included as a guide.
All suitable material excavated is to be utilized within the limits of the embankments. Materials considered unsuitable by the Engineer or his or her Inspector shall be disposed of outside the working limits and neatly trimmed.
3. EARTH EMBANKMENT CONSTRUCTION
The Contractor shall be responsible for selecting material from excavations which are part of this Contract or when approved by the Engineer or Inspector which can be spread and compacted. In no case shall fill containing frozen material, material with an excessive moisture content, or any deleterious materials be used for earth embankment construction.
Earth embankments shall be built to uniform grades and cross sections (see Exhibit 3) and only approved materials shall be used. The depth of the embankment shall be a minimum of 0.6 meters in those areas where no grubbing has been undertaken and the brush has been left as a mat.
4-8
In those areas that have been grubbed, embankments shall be deep enough to provide a uniform surface and to avoid roadway surface water accumulating from surrounding areas. In areas where the brush is required as a mat, the Contractor shall utilize brush from the roadway right-of-way, unless otherwise directed by the Engineer or Inspector.
4. DITCHES
All ditches pertaining to the drainage of the road whether within the limits of the right-of-way or not, shall be considered part of the Contract. All materials excavated from ditches if suitable for constructing roadway fills shall be deposited in adjacent embankments. Materials not suitable for roadway fills shall be deposited in flat waste banks. Ditches shall be a minimum of 0.6 meters deep and a maximum of 1.2 meters deep, unless otherwise specified by the Engineer.
All side slopes must be scaled down and all rocks and fragments, liable to slide down the slopes and block the drainage, shall be removed to the satisfaction of the Engineer.
All drainage is to be so channelled as to avoid damage to roadway areas by erosion.
Hills over 215 meters long with grades in excess of 10% shall have culverts with baffles on one end and cutoff ditches every 150 meters along the road as shown in Drawing Number 5. A baffle can be constructed from gabion baskets, wooden structures, rock walls or other materials prior approved by the Engineer (gravel or sand is unacceptable). Unless otherwise specified, the height of the baffle shall be a minimum of one-half the diameter of the culvert requiring the baffle. Specific areas where this is required are indicated in the Construction Specifications.
5. ROADWAY SURFACE
The subgrade surface of both cut and fill sections shall be finished to the required cross section. The surface shall be of suitable granular material, placed to a minimum depth of ten (10) centimeters, compacted and sufficiently crowned to permit runoff. No stones larger than fifteen (15) centimeters shall be used in the construction of the top thirty (30) centimeters depth of surface. Roadway Surface includes all turnarounds and pull offs.
In some instances the Owner may designate a pit from which surfacing material is to be obtained in a quantity as per the unit price table. In instances where the contractor derives suitable surfacing material from the ditch or right of way rather than from the designated pit a deduction will be made to the unit quantity equal to the distance not surfaced from the designated pit.
4-9
6. MOBILIZATION AND DEMOBILIZATION
The Contractor is responsible for mobilization and demobilization of his or her equipment and plant to and from the job site, and shall include all cost in the unit price tender quotation. The Contractor is to move all equipment and plant and travel over the present roads in a manner that would minimize the interference with others working in the area.
7. COMPACTION
Compaction resulting from the normal traffic of dump trucks during construction is considered sufficient. However, the Contractor is required on return trips to route his or her trucks and earth moving equipment to the softer side shoulders of the road in order that these may be compacted to a degree similar to the travelled centre portion of the road. Compaction by track vehicles (including excavators) is not sufficient.
Should little or no traffic by wheeled dump trucks result during construction, the Contractor is required to effect an equivalent degree of compaction by means of a rubber tire compactor. This operation is to be carried out just prior to final grading. Any resulting soft or uneven areas are to be redressed.
8. FINAL GRADING
After all traffic by heavy construction machinery has ceased, all road surfaces, including turnarounds and pull offs, shall be given a heavy and thorough grading by a wheeled grader so as to give a proper crowned and even surface to the road. The Contractor shall not leave windrows of graded material on the shoulders of the road.
9. PAYMENT
Payment will be made at the unit prices listed in the "Schedule of Items and Price", for providing all services, labour and equipment required to construct all earth works for the roadway, including brushmatting.
10. ROCK EXCAVATION
In most cases rock excavation is to be avoided. Should rock outcrops be encountered, the Engineer shall decide if it is appropriate to build the road over rock by raising the road profile in which case the Contractor shall be responsible for providing the necessary fill up to one (1) meter in depth. There shall be no extra payments for the one (1) meter depth of fill supplied. However, the Owner will pay extra for fill greater than one (1) meter depth as determined by the Engineer or Inspector.
4-10
If rock may be encountered, included in the tender, "Schedule of Items and Prices", is an estimated quantity of rock excavation that may be required. Should the Engineer deem that this rock blasting and excavation be necessary, the Inspector or the Engineer, priorto blasting, shall measure and determine the actual quantity of rock to be blasted and excavated. No measurements shall be taken until the Contractor removes all overburden and loose rock. The Engineer may then order in writing that the blasting and excavation be carried out and payment shall be made at the unit price tendered for rock excavation.
Soft or loose rock (i.e. shale) considered by the Engineer as suitable for ripping and/or excavation without the use of explosives shall not be subject to extra payment but shall be considered as part of the tendered normal excavation and grading items.
If rock excavation is not included in the contract, the Contractor, Engineer and Owner will negotiate a unit price for carrying out the necessary blasting and excavation, and then the Engineer may authorize that it be done. Payment shall be at the agreed unit price per cubic meter for each rock obstruction so removed.
If agreement on a price cannot be reached, the Engineer may order that the work be carried out by forced account on the following basis:-
i) Basic wages or salaries paid to all on site personnel required to perform the work in accordance with direction and devoting their exclusive attention to this work.
ii) Twenty-five percent of item (i) which shall cover the cost of clerical work, Workplace, Health, Safety Compensation, holiday pay, unemployment insurance, other necessary insurance and overheads.
iii) Rental of construction equipment and tools, other than small tools customarily provided by tradesmen at the going rates for similar equipment in the area, subject to prior approval.
iv) No compensation for extra work or material shall be allowed unless such work or material is ordered in writing by the Engineer.
v) Fifteen percent of the sum of items (i), (ii) and (iii) which shall be considered as covering all other expenses and profit.
Or the Owner may have the work done by others in which case the Contractor may resume his or her work in the vicinity of the rock excavation upon completion of the work by others.
If the rock work is done by others, the Owner and the Engineer shall make every effort to have the work done as expeditiously and with as little interference with the Contractor as possible. The Contractor shall not interfere with the rock work and shall make no claim for any delays or inconvenience suffered.

ROADWAY EXCAVATING, GRADING AND SURFACING - CLASS “B”(SECTION 4)
1. DESCRIPTION
This work consists of the excavating and grading of materials to construct a roadway subgrade to the minimum top width, cross section and general profile indicated in the “Construction Specifications”, and the surfacing of the subgrade for the Class “B” road portion of the contract. All construction shall be of suitable materials and, as required, to permit loaded trucks to travel the normal speeds indicated in the “Construction Specifications”.
2. EXCAVATING
Earth shall be excavated as required to complete earth cuts, ditching, sub-excavation and shall include hauling, handling and disposal as directed.
The Contractor may, with the approval of the Engineer or Inspector, excavate outside the limits of the roadway for the purpose of obtaining suitable and/or sufficient material to complete embankments. All holes/pits are to be filled in with grubbing material.
All earth cuts shall be finished to true cross sections as excavations progress.
The Contractor is responsible for constructing the road to the grades indicated on the road profile. These grades shall govern. Volume of cuts and fills indicated on the profile are based on overburden estimates and are only included as a guide.
All suitable material excavated is to be utilized within the limits of the embankments. Materials considered unsuitable by the Engineer or his or her Inspector shall be disposed of outside the working limits and neatly trimmed.
3. EARTH EMBANKMENT CONSTRUCTION
a) The Contractor shall be responsible for selecting material from excavations which are part of this Contract or when approved by the Engineer or Inspector which can be spread and compacted. In no case shall fill containing frozen material, material with an excessive moisture content, or any deleterious materials be used for earth embankment construction.
Earth embankments shall be built to uniform grades and cross sections (see Figure 3) and only approved materials shall be used. The depth of the embankment shall be a minimum of 0.6 meters in those areas where no grubbing has been undertaken and the brush has been left as a mat. In those areas that have been grubbed, embankments shall be deep enough to provide a uniform surface and to avoid roadway surface water accumulating from surrounding areas. In areas where the brush is required as a mat, the Contractor shall utilize brush from the roadway right-of-way, unless otherwise directed by the Engineer or Inspector.
4-8
b) Subgrade Surface- The subgrade surface of both cut and fill sections shall be finished to the required cross section. The surface shall be of suitable granular material, compacted and sufficiently crowned to permit runoff. No stones larger than fifteen (15) centimeters shall be used in the construction of the top thirty (30) centimeters depth of surface.
c) All ditches pertaining to the drainage of the road whether within the limits of the right-of-way or not, shall be considered part of the Contract. All materials excavated from ditches if suitable for constructing roadway fills shall be deposited in adjacent embankments. Materials not suitable for roadway fills shall be deposited in flat waste banks. Ditches shall be a minimum of 0.6 meters deep and a maximum of 1.2 meters deep, unless otherwise specified by the Engineer. All ditches shall be a minimum of 1.2 meters wide at the bottom.
All side slopes must be scaled down and all rocks and fragments, liable to slide down the slopes and block the drainage, shall be removed to the satisfaction of the Engineer.
All drainage is to be so channelled as to avoid damage to roadway areas by erosion.
Hills over 215 meters long with grades in excess of 10% shall have culverts with baffles on one end and cutoff ditches every 150 meters along the road as shown in Drawing Number 5. A baffle can be constructed from gabion baskets, wooden structures, rock walls or other materials prior approved by the Engineer (gravel or sand is unacceptable). Unless otherwise specified, the height of the baffle shall be a minimum of one-half the diameter of the culvert requiring the baffle. Specific areas where this is required are indicated in the Construction Specifications.
d) Compaction- Compaction resulting from the normal traffic of dump trucks during construction is considered sufficient. However, the Contractor is required on return trips to route his or her trucks and earth moving equipment to the softer side shoulders of the road in order that these may be compacted to a degree similar to the travelled centre portion of the road. Compaction by track vehicles (including excavators) is not sufficient.
Should little or no traffic by wheeled trucks result during construction, the Contractor is required to effect an equivalent degree of compaction by means of a rubber tire compactor. This operation is to be carried out just prior to final grading. Any resulting soft or uneven areas are to be redressed.
e) Final Grading of Subgrade- After all traffic by heavy construction machinery has ceased, all road surfaces, including turnarounds and pull offs, shall be given a heavy and thorough grading by a wheeled grader so as to give a proper crowned and even surface to the road. The Contractor shall not leave windrows of graded material on the shoulders of the road.
4-94. ROADWAY SURFACING
Surfacing shall consist of the borrowing, loading, hauling, spreading and grading of acceptable surfacing material. The surfacing shall be deposited in a layer ten (10) centimeters deep by 7.5 meters wide (750 cubic meters/kilometer).
The estimated quantities of surfacing indicated in the tender are pre-construction estimates based on surface observation only. Actual quantities of surfacing to be carried out shall be ordered by the Engineer or the Inspector as construction progresses. The Contractor shall make no claims for loss, damages, anticipated profits or otherwise on account of any differences which may be found between the quantities of work actually ordered or done and the estimated quantity contained in the Tender.
The Engineer and/or Inspector reserve the right to order that all the surfacing or any portion thereof be carried out as construction of the subgrade progresses or after all subgrade work is completed.
Surfacing material shall come from the pit(s) designated in the “Construction Specifications” unless it is found that the material in the ditch is suitable for surfacing and hence surfacing material need not be trucked from the designated pit(s). The Contractor will not be paid for surfacing material obtained from the ditches. Should the acceptable surfacing material run out in the designated pit(s), the Inspector or the Engineer shall order that the remaining required material come from another existing source(s) or one discovered during construction.
5. MOBILIZATION AND DEMOBILIZATION
The Contractor is responsible for mobilization and demobilization of his or her equipment and plant to and from the job site, and shall include all cost in the unit price tender quotation. The Contractor is to move all equipment and plant and travel over the present roads in a manner that would minimize the interference with others working in the area.
6. PAYMENT
a) Subgrade- Subgrade excavation and grading shall be paid at the tendered unit price per kilometer for the length of subgrade completed to the satisfaction of the Engineer.
Payment shall be for providing all services, labour and equipment required to construct the subgrade as specified.
b) Surfacing - Payment shall be made at the tendered unit price per kilometer. Payment shall be for providing all services, labour and equipment required to construct the subgrade as specified.
4-10
7. ROCK EXCAVATION
In most cases rock excavation is to be avoided. Should rock outcrops be encountered, the Engineer shall decide if it is appropriate to build the road over rock by raising the road profile in which case the Contractor shall be responsible for providing the necessary fill up to one (1) meter in depth. There shall be no extra payments for the one (1) meter depth of fill supplied. However, the Owner will pay extra for fill greater than one (1) meter depth as determined by the Engineer or Inspector. If rock may be encountered, included in the tender, "Schedule of Items and Prices", is an estimated quantity of rock excavation that may be required. Should the Engineer deem that this rock blasting and excavation be necessary, the Inspector or the Engineer, prior to blasting, shall measure and determine the actual quantity of rock to be blasted and excavated. No measurements shall be taken until the Contractor removes all overburden and loose rock. The Engineer may then order in writing that the blasting and excavation be carried out and payment shall be made at the unit price tendered for rock excavation.
Soft or loose rock (i.e. shale) considered by the Engineer as suitable for ripping and/or excavation without the use of explosives shall not be subject to extra payment but
shall be considered as part of the tendered normal excavation and grading items.
Hard rock blasting and excavation ordered by the Engineer shall be paid at the tendered unit price for this item for the actual quantities as determined by the Engineer prior to blasting All rock measurements are to be rounded to the nearest whole cubic meter. If in the opinion of the Engineer the Contractor has exercised due care in the performance of this rick work and due to circumstances beyond the Contractor’s control, over break has occurred, then over break within 300 millimeters of theoretical back slopes and/or cross section will be paid for as solid excavation. No payment for over break will be considered for surface boulders or ditch line excavation.
Should the ordered quantity of rock blasting and excavation exceed three times the estimated quantity contained in the “Form of Tender” (and does not increase the final contract price by more than 25% of the total tender price as stated in Clause 32 of the General Conditions), the Engineer reserves the right to institute that payment be made by forced account on the following basis:
i) Basic wages or salaries paid to all on site personnel required to perform the work in accordance with direction and devoting their exclusive attention to this work.
ii) Twenty-five percent of item (i) which shall cover the cost of clerical work, Workplace, Health, Safety Compensation, holiday pay, unemployment insurance, other necessary insurance and overheads.
iii) Rental of construction equipment and tools, other than small tools customarily provided by tradesmen at the going rates for similar equipment in the area, subject to prior approval.
4-11
iv) No compensation for extra work or material shall be allowed unless such work or material is ordered in writing by the Engineer.
v) Fifteen percent of the sum of items (i), (ii) and (iii) which shall be considered as covering all other expenses and profit.
8. BLASTING OF DITCHLINE
In the event of blasting of ditchline is required, the final dimensions of said work is to be in accordance as per Drawing No 11
9. GEOTEXTILES AND GEOGRIDS
The Contractor shall follow all manufacturers instructions for the proper installation of any geotextiles or geogrids supplied by the Owner or Inspector. The cost of such installation will not be considered an extra; but rather considered as part of Roadway Excavation and Grading.
APPENDIX I
Methodology for Culvert Installation In The Dry Culvert Installation All culverts to be installed in fish bearing streams must be done “In the Dry”. This refers to isolating the work site (i.e culvert placement site) from the flow of water in an effort to reduce the impact of silt and fines on fish and fish bearing habitat. This can be achieved through the use of cofferdams, pump-around systems, temporary diversions or a combination of all three.
Fill used in cofferdams must be clean and sediment free. The dam must be of sufficient height and strength to prevent overtopping or collapse if water levels suddenly rise. Normally a dam consists of sandbags with a middle layer of plastic and an outer layer of rocks or sand bags. A steel plate diversion can be constructed and driven into the stream to act as a dam if conditions permit.
If a temporary diversion channel is used: o It should be placed parallel and close to the existing
channel o Lined with durable plastic and secured with rock o Stake the plastic at the top of the channel side slopes o Once secure, remove the material at the upstream point of
the diversion o Construct a cofferdam below the site of culvert
installation o Pump any residual water from the isolated area into
vegetated area o Once culvert is installed removed the downstream end of
diversion first.
If a pump around system is used: o Construct a cofferdam above the site of the culvert
installation o Establish a water pumping system to transfer water around
the work area o Ensure the intake pipe is located in the lowest part of
the stream o Ensure a screen is placed over the intake to prevent fish
intake o Locate the discharge hose in a stable area of the
streambed o Create a stable area with sandbags, rock or plywood if
necessary o Pump any residual water from the isolated area into
vegetated area o Once culvert is installed removed the downstream
diversion first. o NEVER leave the pumping system unattended
Streambed Foundation All culverts should be installed on a firm and level streambed foundation to provide proper support and prevent sagging.
where the stream bed is solid and embedding cannot be achieved, apply a thin layer of clean gravel 15-20 cm thick. Remove any rocks which would impede installation. Where the stream bed is soft, excavate to firm ground and apply a thin layer of clean gravel; do not compact the streambed foundation material. Ensure the culvert is embedded into the stream bed at least 20% the diameter. In very soft conditions a slight camber (rise) should be applied to the culvert during installation. As the road settles so will the culvert; rule of thumb is to arch the centre 2.5 cm for 3 m of culvert length. The culvert should be installed at a slight grade to accommodate fish passage. This grade should not exceed 0.5%.
Backfilling Once the culvert is properly situated it should be backfilled with sufficient granular material to provide even support on both sides and compacted to prevent culvert washouts. The procedure should include:
the use of clean, granular material less than 5 cm in diameter. It should not consist of mud, fine sand, or any form of woody material. compaction that can be achieved with hand tampers or mechanical equipment. Excavator buckets can be utilized for culverts less than 900 mm. Compaction should be done a distance of ½ the diameter the culvert opening. the placement of fill in lifts of 10 to 15 cm on both sides of the culvert.
compaction of fill along the haunches should be done by hand to prevent shifting or lifting of the culvert. Ensure there are no voids or soft spots left between the culvert and the streambed. final lift of fill should be a minimum of 60 cm above the top of the culvert
Stabilization (riprap) The contractor must ensure that the road embankment slope is at 1.5:1 (as per Drawing No.3) for a minimum of 10 m on all sides of culverts. The immediate area around culvert inlet and outlet is to be compacted (with bucket) prior to placement of riprap or armour stone. Riprap shall be laid at the upstream and downstream end of all culverts. The Contractor shall utilize stones with an average diameter between 20-30 centimetres as riprap. The Contractor shall place by hand, larger stones at the bottom and take care to place the stones as close together as possible.
Replacing Culverts The same standards and guidelines for new culvert installations apply to replacement of existing culverts. Prior to starting work sediment and erosion control structures need to be established to intercept and trap sediment before it reaches the watercourse. These devices are normally fashions from straw bales or silt fences and must remain in place and intact until the new culvert is installed and any risk of sedimentation is minimized.
