The total station will be set up on the nearest or most convenient control point to ease the completion of the survey. Ground measurement points will be scattered around the first control point to get as much shots as possible to the surrounding area. As long as the project area is still visible in the total station’s range, ground points will be continuously established and measured with sufficient number necessary to accurate the calculation of the elevation and the general topographic profile. When the areas of the project site are not visible, additional traverse stations will be established and set up on the next best convenient location. The total station will then be set up on the next station. Many traverse stations will be made in order to fully cover the entire project site. Ground measurement points will again be scattered around the project site in order to gather the most accurate data possible.

A complete traverse of all the control points and traverse stations covering the entirety of the project site will be conducted to check that the data loop is closed. This will also ensure accuracy of the resulting data.

UsingTotal Station

All dimensions, angles, and elevation will be surveyed in accordance with the approved drawing. Set the equipment from the very beginning of the work. The surveyor will take a lay out from a designated area and make an interval of 10m for the straight roads and an interval of 5m for the curved roads. During the activity, all data will be recorded. On completion of the works an as-built survey showing dimension, location, angles, and elevation will be prepared and submitted.

Using GPS Survey Equipment Set the equipment on one area. By the help of the aide, he will walk up to max radius of 500m on open surface area and max radius of 100m on obstructed area. The data will be recorded on the controller handed by the surveyor. All data can be read with the use of

the GPS software and CADD to see the topographic profile of the area surveyed.

Undertaking Hydrographic Survey After all the horizontal and vertical control points are established, the alignment of the route will be surveyed. First, the general grid for the area will be determined using the design criteria provided by the engineering designer along the project area being surveyed. Shots will be made on the pre-agreed intervals with the designers along the project area.

Water depth shots will be surveyed next based on the agreed interval. In most cases, a spacing of 20 meters between points is used. RTK - based GPS is connected with the high - end echo sounder to produce resulting data with both the water depth and horizontal position linked with each other, as compared to the older instruments and methodologies where they have to be processed during drawing preparations.

The depth of the water and the profile of the sea or the grid for area based surveyed at the defined stations will then be measured then plotted on the plans and drawings.

As the GPS points were establishment, all best practices manuals specified techniques and requirements will be followed. The terms of reference of the project will also be followed at all times. In cases where deviations are necessary, proper consultation will always be made with the Client identified Cognizant personnel. Then approval of the proposed changes/ solutions to issues/ problems will be solicited first before proceeding.

2.5.1.2 Fabrication of Precast Blocks All pre cast block concrete shall be cast in forms at the nearby site.

2.5.1.3 Jetty Excavation

Pre-excavation

Establish the location of the line of excavation based on the drawing and specification requirement. Cleaning and grubbing refers to grass, roots, stumps, vegetation, pavement, sidewalks and surface obstruction of any kind that are required to be temporarily or permanently removed and that lie within the actual areas to be excavated.

Location of existing underground utilities must be determined before excavation works commence so that progress of excavation will not be delayed. Test pits should be conducted when needed or when order by the Client.

Determine the type of soil, destabilize excavation can fail that can result on a different types of accidents. Provide the appropriate protective measures on trenches to prevent the occurrence of accidents that may occur during the excavation process. Use shoring, sheeting, sloping, and bracing whichever is appropriate.

Put in place adequate support at the side faces of excavation or employ measures to ensure the safety and stability and avoid the damage to the foundations of existing adjacent structures.

Excavation Proper

Page 22: 48325-001: 150 MW Burgos Wind Farm Project...BurgosJetty shall be in accordance with Method Statement No. PMDB001BIN - Survey Works (1.00), PMDD002BIN - Tree Cutting& Tree Balling

PMDE001BIN – Construction of Burgos JettyRevision 0 | 14/10/2013

On excavation using mechanical excavator, position the equipment on a stable location with a distance that can be safe from the soil erosion during excavation. Equipment on the side of the trench increases the load on the trench wall that can cause soil erosion. Excavated soil that has been stockpiled at the edge of the trench also adds pressure on the trench walls which may cause soil erosion. To mitigate, place excavated soil at least 0.60 meters from the edge of the trench.

Surface water flowing towards the area of excavation should be intercepted by cut-off drain and led away from the working area. Care must be taken that the toes of slopes are not weakened by the provision of drainage.

Random checking of designed invert elevation will be maintained while excavation is on progress to avoid over breaks. Excavated materials will be loaded directly into the truck for proper disposal.

Once the desired elevation is attained, place the geo textile all over the area to be covered by the jetty and put leveling sand 20 cm. thick. Lying of geo textile shall be done by expert divers.

On dredging, place the rockfill materials in between the corals using a dump truck for temporary access road to reach the area to be dredged. Position the equipment on a stable location within as safe distance of approximately 1-1.5m away from the edge. Start dredging the corals using an excavator to the required depth. Depth will be verified by the divers. Note that while divers are at verifying the depth, there will be no equipment operation to avoid any untoward incidents.

While dredging is on-going, another excavator will remove the excavated materials for disposal.

Post-excavation Excavation shall include disposal of unsuitable and excess excavated materials off-site; no excavated material suitable for re-use shall be disposed from the site except with the permission of the Client. Location of the disposal area should meet the legal requirement or the Client at its own discretion may identify an area within the project site as a disposal area.

2.5.1.4 Road Compaction

When uniform mixed, the mixed shall be spread to the plan thickness, for compaction.

Where the requirement thickness is 150 mm or less, the material may be spread and compacted in one layer. Where the required thickness is more than 150 mm, the materials shall be spread and compacted in two or more layers of approximately equal thickness, and the maximum compacted thickness of any layer shall not exceed 150 mm. All subsequent layers shall be spread and compacted in a similar manner.

The moisture content of the material shall, if necessary, be adjusted on prior to compaction by watering with approved sprinklers mounted on trucks or by drying out, as required in order to obtain the required compaction.

Immediately following final spreading and smoothing, each layer shall be compacted to the full width by means of approved compaction equipment. Rolling shall progress gradually from the side to thecenter, parallel to the centerline of the road and shall continue until the whole surface has been rolled.

Any irregularities or depressions that develop shall be corrected by loosening the material at these places and adding or removing materials until surface is smooth and uniform.

Along curbs, headers, and walls, and at all places not accessible to the roller, the material shall be compacted thoroughly with approved tampers or compactors.

tightened up and welded to beam steel reinforcement.

The grout for the block must be soft and dry. Pact mortar of at least 25MPa concrete strength is advisable.

Erection of Precast Modules

Precast modules shall be properly positioned to match one another as shown in the drawings. Care must be observed to match connecting plates within a tolerances of 6mm each day way.

Welding

It is emphasize here the importance of the following required welding of connection as shown in the drawings. The strength of the member being just as good as its connection, it is imperative that welded connection should never be weaker than the bars or plated to be connected. All welding works should conform to the AWS specifications. When the bars or plates to be welded do not come close to each other as required, but lap its connections, bars may be bent to the desired direction but always be done within an offset of one (1) in six (6) and a bar by cross welded at the point of offset to prevent splitting of bursting of concrete when the design loads are imposed. Welding to any embedded metal which might cause damage to the adjacent concrete by spalling, in particular where the expansion of the beaten metal is restrain by concrete, shall be welded.

Mortar Packing of Joints All connections must first be thoroughly inspected before any concrete packing of the joint is done. Concrete surface of the component members framing into the joint must be clean and previously wetted before the joint is filled with dry mix, as much as consistency would allow, in order minimizing shrinkage admixture in the mortar is highly desirable. The joint must be thoroughly packed down to the bottom of the joint. Aggregatesof 12mm maximum size may be used. The mortar mix should be at least 21Mpa.

Concrete Topping Concrete topping over beams and precast blocks should be done according to the requirements of the drawings. The topping shall be screened

Page 28: 48325-001: 150 MW Burgos Wind Farm Project...BurgosJetty shall be in accordance with Method Statement No. PMDB001BIN - Survey Works (1.00), PMDD002BIN - Tree Cutting& Tree Balling

First Bal four

PMDE001BIN – Construction of Burgos JettyRevision 0 | 14/10/2013

vibrated to minimize segregation of concrete. Prior to placing concrete, the top surface of the beams and double test must be cleaned of all foreign materials and soaked with water. It is important that all reinforcements be checked prior to placing of topping. Steel wires mesh on the slab topping should be uniformly positioned at mid-depth of the topping. Minimum concrete strength of the topping must be 28MPa.

Alteration of Precast Units

Alteration of precast units after erection not provided for during fabrication when deemed should be made before commencement of such work. Alterations must be submitted for approval. This is important to insure that the structural capacity of the units is not impaired.

2.5.1.7 Rock Fill

Rock wall width and length where based on the

given design and specification. This dry stacked

rock walls are typically built on an incline area or

as against a hillside because it can be used as a

tool to prevent soil erosion.

Selection of Stones Selection of stones from a stone supply yar should pass and follow the standard procedures allowed in construction. Measurements of the items used on rock fill were important as ot affects the quantity and size of stones needed. Dry stack walls can typically be made from three types of stones: round filed stones, relatively flat stacking stones, and uniformly cut dressed stones. Each type will give a different look so make sure to picture out the result to determine which would be the best to fit. Note that flatter stones tend to be easier to work with than rounder ones, as they are more suited for stacking.

Lay Out the Wall Area Cutting away a bank where done through excavation process. Then building the wall as of the rock fill and back filling go on creating a terrace effect.

Put and pull a string line to determine the alignment of the slope. The length of the string varies upon the upper and lower part of the wall. Sideways strings are also put up to assist in maintaining the right and correct placing of the rocks. Digging a Ditch Dig a ditchbelow the ground level. This ditch will act as the wall's footing and prevent the rocks from sliding forward due to pressure from the earth behind. Cutting the ditch into native soil rather than loose added soil, as the former provides a more stable foundation for the wall. Level the foundation trench. Smooth over the ground beneath your wall and line it with crushed stone pieces called stone screenings, stone dust or fines. This material will also be useful for filling in gaps.

Stacking of Rocks Stack the larger rocks in the ditch. Place the flat side facing for ward, and slanted back about 8 degrees. The rock should just miss touching the string line, and be supported by dirt filled in behind it. Do this for the length of the wall, with each large rock touching the one next to it.Fill cement behind the large rocks and tap the earth firmly, while letting the 8 degree slant hold the rock in place by gravity.

Complementary Rocks

Complementary rocks to fill in the spaces in between the large rocks. These rocks may be smaller, but need to be a shape that fills the void between the large rocks. Lay the rock flat side out and support it with concrete filled in behind it. These rocks also lay back by 8 degrees.

Layering of Rocks

Continue placing the second layer of rocks and so on and so forth, so that spaces between the first layers of large rocks are filled. Fill out the entire span of the trench. You can add water to the fill to make it settle. Square off the top of the wall with smaller stones to give it a neat, straight and flat appearance.

2.5.1.8 Installation of Armour Rocks

Site Preparation

Clearing and grubbing should be kept to the

minimum required to meet the specifications

shown on design drawings. The slopes left free of

brush, trees, stumps or other objectionable

materials and dressed to a smooth surface. Banks

are to be trimmed uniform slope, as indicated on

drawings. Loose, soft or spongy material, and

large rocks projecting through the slope are

removed and the resulting minor potholes or

hollows filled with selected no cohesive materials

and compacted as directed. If a toe trench for

scour protection is required, it is constructed

during site preparation.

Placing Filter Layers

The materials for gravel filter layers are inspected

for quality. Hardness and durability of rock and

presence of fines must be of its best quality. And

compliance with gradation by the site engineer.

The filter layer materials are spread evenly on the

prepared bank, to the dimensions on the drawings.

They are sometimes extended beneath launching

aprons or toe berms. The layers are usually placed

by techniques that do not result in segregation of

the rock mass. Compaction is not required but the

surface should be smooth and free of mounds,

dips or windrows.

Quality

Stone used for rock riprap should be hard, durable,

angular in shape, resistant to weathering and

water action, free from overburden, spoil, silt and

clay or organic material and meet the specified

gradation. Dirty rock which contains clay, silt, soil

or organic materials but is otherwise acceptable is

usually washed prior to delivery to the site.

Specifications for rock used as riprap typically

include rock density or specific weight, rock shape,

and rock hardness and durability.

Control of the size and gradation of rock riprap

placed on a bank is one of the most important

aspects of riprap construction yet it can be very

difficult to achieve. Visual inspection of individual

loads of rock delivered to the site is an important

part of quality control.

For large projects, a sample of rock in the quarry

that meets the specified gradation can be provided

as a visual reference for the machine operators.

Marked samples of the D100, D85, D50, and D15

rocks are often particularly helpful. A similar

sample can be placed at the construction site for

reference.

Daily, or more frequent, line sampling of in-place

riprap provides a check on gradation. The

procedure is to lay a measuring tape across the

surface of the riprap and measure the dimensions

(usually the b-axis) of each stone that falls under a

fixed spacing, such as every 2 m along the tape.

Measure at least 50 rocks for each line sample.

Tabulate the stone dimensions from largest to

smallest, calculating the percent finer for every fifth

rock in the sample. Plot a curve of percent finer by

diameter and compare it to the gradation curve. If

the sample rock appears undersized, additional

sampling is required. If further sampling confirms

that the rock is undersized, construction can be

stopped and the procedures in the quarry re-

evaluated.

Rock Riprap Placement

The rock is transported and placed by methods

that avoid segregation: end dumping, dumping into

chutes placing or moving by dragline buckets, or

spreading by bulldozers are generally not

acceptable construction practices. Care should be

taken to prevent cracking or breaking of rock riprap

by crushing under machine tracks. Each truckload

of rock brought to the site should provide a

complete range of the rock sizes in the gradation.

Rocks are placed by bucket load to the required

thickness, providing a reasonably well-graded

mass with the minimum of voids. Large stones are

placed along the toe or distributed evenly

throughout the mass. Clusters of small or large

stones are avoided.

For above water work, stones are placed from the

base of the slope to the top in one operation. For

high banks, it may be most suitable for two

excavators to complete the work, one at the base

of the bank and one at the top. Care is required in

placing rock to avoid disturbing the filter layer(s).

For underwater placement, clamshells are typically

used to place rock on the streambed or the toe of

the bank. Dumping of rock is not recommended as

it produces a poor distributionof material. Quality

control, which is often based on GPS-controlled

soundings or dive inspections, is beyond the scope

of this document.

Often the surface of the rock is left rough.

However, in some circumstances, quarry spalls are

used to fill voids in the revetment surface creating

a smoother surface

2.5.1.9 Installation of Rubber Fender

One of the necessary pieces of equipment when you have a jetty is rubber fender. These boat dock bumpers are what keep your boat from colliding with the jetty and causing damage to the boat, the dock, or to both. Mostly made out of vinyl, rubber, or plastic, dock bumpers also keep boats from serious damage during storms as they bang up against the jetty. Installing rubber fender is a very easy task and can be done within a few hours. Measuring the Dock

Before installing the rubber fender, know how many you are going to need. As a general rule, each boat that will be tying to the dock should have at least two that will keep it away from the dock. Measure the overall dock and decide on how many boats will fit there. Once decide d just use two for each boat.

First Bal four

PMDE001BIN – Construction of Burgos JettyRevision 0 | 14/10/2013

Measuring for the Right Height

After measuring the jetty and determining where the rubber fenders will be placed, it will need also to measure down towards the water for the best height. If the fender were put up too high, the boat will slide under them and they are useless. The best way to do this is to pull your boat alongside and mark the jetty where the railing is. This is where the middle of bumper should be. Attach Mounting Bracket Take the mounting bracket that the rubber fender will be attached to and line it up on the jetty. Place a small level on it, to make sure it is even and mark the holes with a marker. Use your cordless drill with the right size drill bit to drill the hole.

Place the bracket back on to the jetty and slide the bolt through the hole. Use your socket wrench and tighten up the bolt from the underside of the dock. You may have to reach under, or get into the water if it is too much of a reach. Repeat as necessary for the other holes if any. Seal Screws and Drill Holes Use liberal amounts of silicone on the underside of the jetty and cover the entire surface of the hardware and the hole. Dab a thin line on the front of the jetty if any the mounting hardware is showing.

2.5.1.10 Installation of Steel Bollard

Lay out the desired location for the steel bollard placement and mark the ground of the jetty of its approximate centre point.Dig a hole to the mark made using a post hole digger or any digging equipment. The diameter of the hole should be the diameter of the bollard plus 6 inches and it should be 18 to 24 inches deep.

Put concrete cement to paste the bollard to the jetty. Add an extra 1/2-gallon of water to make the mix slightly wetter. This will help the concrete flow to fully pack the post hole.Insert the steel bollard into the hole and use a level to hold it plumb.Put the concrete mix into the hole opening around the perimeter of the bollard. Gently tap the bollard's side with a rubber mallet or hammer as you insert the concrete mix to help pack the mix. Leave the

Otherwise, fill the mix up to the ground level. Allow the concrete mix to cure for a minimum of 48 hours to complete the bollard installation.

2.5.1.11Road Base Course

Placing The aggregate sub base material shall be placed at a uniform mixture on a prepared sub base in a quantity which provides the requirement compacted thickness. When more than one layer is required, each layer shall be shaped and compacted before the succeeding layer is placed.

The placing of material shall begin at the point designated by the engineer. Placing shall be from vehicles specially equipped to distribute the material in a continuous uniform layer or windrow. The layer or windrow shall be such size that when spread and compacted the finished layer be in reasonably close conformity to the nominal thickness shown on the Plans. When hauling is done over previously placed material, hauling equipment shall be disperseduniformly over the entire surface of the previously constructed layer, to minimize rutting or uneven compaction.

Trial Section Before the sub base construction is started, the contractor shall spread and compacted trial section as directed by the Engineer. The purpose of the trial section is to check the suitability of the material and efficiency of the equipment and construction method which is proposed to be used by the Contractor.

The contractor must use the same material, equipment, and procedures that propose to use for the main activity work. One trial section of about 500 square meters shall be made for every type of material and/or construction equipment/procedure proposes for use.

If the trial section shows that the proposed material, equipment or procedures in the engineer’s opinion are not suitable for sub grade, the material shall be removed at the contractor’s expense, and a new trial section shall be constructed.

If the basic conditions regarding the type of material or procedure change during the execution of the work, new trial section shall be constructed.

Spreading and Compaction When uniform mixed, the mixed shall be spread to the plan thickness, for compaction. Where the requirement thickness is 150 mm or

less, the material may be spread and compacted

in one layer. Where the required thickness is more

than 150 mm, the aggregate sub-base shall be

spread and compacted in two or more layers of

approximately equal thickness, and the maximum

compacted thickness of any layer shall not exceed

150 mm. All subsequent layers shall be spread

and compacted in a similar manner.

The moisture content of sub base material shall, if necessary, be adjusted on prior to compaction by watering with approved sprinklers mounted ontrucks or by drying out, as required in order to obtain the required compaction. Immediately following final spreading and smoothing, each layer shall be compacted to the full width by means of approved compaction equipment. Rolling shall progress gradually from the side to the center, parallel to the centerline of the road and shall continue until the whole surface has been rolled. Any irregularities or depressions that develop shall be corrected by loosening the material at these places and adding or removing materials until surface is smooth and uniform. Along curbs, headers, and walls, and at all places not accessible to the roller, the sub-base material shall be compacted thoroughly with approved tampers or compactors.
