Descriptions

Summary:●Erect ~ 590m of stock fencing●Erect ~ 5 m of post and rail fence●Supply and install 2 x access gates in fence line●Install 2x livestock drinking troughs with hard standing area●Lay ~ 420 m of supply pipe to connect troughs and connect to existing mains supply●Plant a total of 180 trees.Work specification and methodology:Please email your quotation or any questions to the email above.Fencing- Stock fencing ~ 590 m.Fence to be constructed using FSC certified, UC4 treated timber and high tensile wire. Strainer posts to be 7-8” diameter and at start, end and major changes in direction, supported by braced struts. Turning posts 5-6” used at minor changes in direction or height. Intermediate posts 3-4” diameter and no more than 11’ apart.80 cm sheep netting with two strands of barbed wire, one above and one below the netting. The finished fence height should be approximately 1.1m (44”).Use of a track machine post knocker is obligatory due to wet ground conditions likely to be encountered.Strainer posts and struts to be no closer than 2 m from the top of a steep bank, or if gentle sloped bank no closer than 2 m to the water’s edge. The tenant has agreed the fence line will be ~ 4 m from the riverbank for the tree planting zone (see Figure 1). Elsewhere the fence line should follow the existing riparian vegetation. The exact positioning of the fence will be agreed between the contractor, landowner, and NWRT before installation.- Supply and hang 2 x 12’ galvanised steel access gates at the locations indicated on the plans including self-closing springs with appropriate tie-back stakes/latches. Access gates should always be hung on gate posts which are railed to a strainer, never hung on the same post that wire is tensioned to.-Erect ~ 5 m of post and rail fence to traverse a drainage ditch at the field edge (Photo 3).Water supply-Install 2 x 75 gallon concrete drinking troughs with ball valves and hardcore standing area at locations shown in plan. Troughs should be of suitable height for both sheep and cattle.-Dig trench to lay ~ 420 m of 25 mm diameter pipe connecting mains supply to drinking troughs. Where the pipe crosses pasture, the trench depth must exceed ploughing depth (minimum 30 cm depth).Tree Planting- A total of 180 trees to be planted using the notch planting method. Plastic guards and wooden/bamboo canes to be used for all saplings and planted a minimum of 2.5 m apart. As many trees as possible should be sourced of a local origin https://naturalresources.wales/media/3119/choosing-provenance-in-broadleaved-trees.pdf.Tree planting can only commence when stock have been excluded from the tree planting zones (i.e., after installation of the stock fence and water supply). NWRT will provide the detailed design for tree planting.All measurements are indicative, and quoted totals will be taken as definitive. It is the contractor’s obligation to clarify measurements to their own satisfaction, as adjustment to totals after completion cannot be made. Any additional works must be approved, otherwise payment cannot be made. Any brash clearing, tree work or other ground works required to install the scheme should be determined by the contractor and included in the initial quote.It is the responsibility of the project officer and contractor to ensure that contracted works are not started WITHOUT A PROJECT OFFICER PRESENT. A project officer must be present at the beginning to brief all parties on the project. Failure to do so will void any contracts (and H&S policies) and payment may not be made. A project officer will meet you on the day of the works at 8am to outline the details. Please let NWRT know the times and dates of all works a minimum of 72 hours before the proposed works commence. A project officer may also follow up intermittently to check on the progress of the project (the frequency of this is dependent upon the complexity of the project). No other work than what is explicitly stated here is to be carried out unless approved by NWRT project manager. It is also the responsibility of the contractor to provide proof that all plant used are fit for purpose, as well as all relevant certifications.NOTE: To register your interest in this notice and obtain any additional information please visit the Sell2Wales Web Site at https://www.sell2wales.gov.wales/Search/Search_Switch.aspx?ID=139330.
