Broads Authority – 2019-24Adrian Sewell – Rivers Engineer Page | 2


1. INTRODUCTION

The Broads National Park is a network of mostly navigable rivers and lakes in the counties of Norfolk and Suffolk. The lakes, known as broads, were formed by the flooding of peat workings. The Broads, and some surrounding land, were constituted as a special area with a level of protection similar to a national park by the Norfolk and Suffolk Broads Act 1988

The area is 303 square kilometers (117 sq. miles), most of which is in Norfolk, with over 200 kilometers (120 miles) of navigable waterways. There are seven rivers and 63 broads, mostly less than 4 meters (13 ft.) deep. Thirteen broads are generally open to navigation, with a further three having navigable channels. The Broads Authority requires up to date hydrographic survey data to assist with its Sediment Management Strategy.

The Broads Authority wishes to employ a specialist surveying contractor to undertake routine hydrographic surveys of the Broads navigation areas for a period of three years with a following two year option.

The hydrographic survey contract will allow the Broads Authority to continue in its proactive approach to dredging operations. Enabling it to identify the volumes of sediment requiring removal to best achieve model user specifications for navigation channel and open water bodies.



2. FORM OF CONTRACT & CONDITIONS

The contract is the NEC3 Professional Services Contract June 2005 (with amendments June 2006). Tenderers will have to familiarize themselves with this contract and the specific details given in the Contract Data.

The contract will be managed as a Term Contract (Option G), whereby items of work and costs will be based on an agreed schedule of standard tasks and rates. The aim of the Task Schedule is to cover all anticipated work. Each task will be commenced by a Task Order, upon which the contractor will provide an estimate. If during the period of the contract the Authority requests a task which is not covered by the Task Schedule then this will be assessed as a compensation event.

In the common one-stage open tender process, qualifications are submitted alongside the proposal, so any company or consortium of companies may submit a proposal. However, proposals will only be evaluated after checking that the respective bidder has met the qualification criteria (that is, this is a pass/fail exercise).

The objective of a qualification process is to set a minimum bar of capability for the Bidder Company or group of companies entering into the tender contract. Setting qualification criteria will reduce the risk of project failure caused by a lack of credentials experience and capacity.

2.1. Conditions of Contract

The conditions of contract are the core clauses and the clauses for main Option G – Term contract; dispute resolution W1; and secondary Option X7 – Delay damages, Option X9 – Transfer of rights and Option Z – Additional conditions of contract; of the NEC3 Professional Services Contract June 2005 (with amendments June 2006).

2.2 The conditions of contract are the NEC3 Professional Services Contract (June 2006) and the following additional conditions.

2.3 Option Z

a) All communications and instructions between the Contractor and the Employer are to be made through the Project Manager, or persons named by the Project Manager.

b) No part of this contract is to be subcontracted unless written approval is given by the Employer.

c) The Employer can cancel this contract and recover any resulting losses if the Contractor, with or without the Contractors knowledge:



I. does anything improper to influence the Authority to give the Contractor the contract; or

II. Commits an offence under the Prevention of Corruptions Acts 1889 to 1916 or Section 117(2) of the Local Government Act 1972.

d) If the Contractor does not have the required cover of insurances stated in section 4.15, the Contractor may state the cost of obtaining the required insurance and this cost must be added to the tender by inclusion in the task schedule.

2.4 Option X7 Delay Damages

Delay damages of £100 shall be paid by the Consultant for each day over the date agreed for the Completion of a task.

2.5 Option X9 Transfer of rights

A. Clause X9.1 applies whereby The Employer owns the Contractors rights over material prepared for this contract by the Contractor.

B. Definition of Data – Unprocessed point cloud data.

2.6 Termination

Standard clauses 90.1 to 92.2 are applicable.

3.3 QUALIFICATION CRITERIA

In the tender evaluation process, the presented methodology for how you plan to undertake and deliver the data plays an essential part of the contract award. We would like to have confidence with your understanding of the Broads environment and our hydrographic needs.

In order to determine this, the evaluation of the returned tenders will be based on a set of qualification criteria (set out below) with particular attention given to a methodology statement on a worked task example (Appendix 1). Tenders will also be scored according to the evaluation matrix, as shown below in Table 1.

The overall pre-qualification criteria will be on the basis of pass or fail elements and a qualitative assessment. In order for the remaining tender documentation to be evaluated by the Broads Authority evaluation panel, tenderers must successfully pass all ‘Pass or Fail’ criteria. Where in doubt, tenderers are advised to contact the nominated contact for advice.

Once the ‘Pass or Fail’ criteria have been assessed, successful tenderers’ responses will be evaluated on a qualitative basis based on the tenderers’ response to the remaining criteria in the tender response document.

Once all tender submissions have been received by the deadline as outlined in this document, the responses will be reviewed individually by a panel of Broads Authority representatives. Once the individual evaluations have been completed, the panel will discuss all scores and confirm an agreed score for each criteria for each supplier to give the final total score.

8.0 GENERAL BACKGROUND INFORMATION/SPECIFICATIONS

8.1 Key Service Dates

The Broads Authority reports on the condition of the navigation and forward dredging programme each April. To allow for this and to take advantage of minimal boat traffic and aquatic plants, it is anticipated most surveys will be programmed in November and December. Each survey will be managed as a separate task and based on costs provided in the Task Schedule.

8.2 Equipment

8.2.1 Survey Vessel

The survey vessel should have a shallow draft and be of an appropriate size to allow work close to the channel edges and maximise data collection in shallow areas.

The tender applicants must be aware that the general waterways depths open to navigation are mostly less than 4 metres (13ft) deep.

The air draft of the survey vessel should also provide minimal disruption to passage through bridges, several of which have a clearance of less than 7ft (2.1m). Information on bridges is published on the Broads Authority website.

8.2.2 Sounding Equipment

The contractor must specify the sounding equipment to be used and provide technical specifications. Multibeam, single beam, swathe, sector and other scanning sounders will all be considered. The likely effective bed coverage in a single pass should be stated. The shallow nature of the Broads will impact on the distance between survey grid lines.

The contractor must specify their intended transducer frequency. The suggested frequency is 200 kHz; however, the contractor should use their experience to select the frequency best suited to pick up the surface of the bed.

In the open water broads the bed is typically fine grained, fluid, low mineral/high organic matter content, deposited sediments. To test and record the accuracy of the stated methodology, ground truthing must be included in the submitted methodology and then undertaken at each defined survey area.

It is anticipated that differential GPS equipment will be used for positional measurement. The equipment should enable the X, Y and Z position of data points to be recorded, accurate to ±50mm. Contractors should quote their anticipated achievable accuracy.

8.3 Survey Methodology:



As detailed in the evaluation criteria, please provide details of the proposed method of survey to achieve the required density of data points.

You should be aware that your overall method statement forms an important part of the evaluation process of the tender reward, and should have a primary aim of reducing any adverse impacts of surveying on local sensitive receivers. As such it should provide (1) an outline to the contractors approach to data collection and quality; (2) the contractor’s environmental credentials, and (3) an approach to health & safety management throughout the delivery process.

8.4 River Navigations

In conjunction with the proposed equipment, the method of survey used must be capable of producing surveyed data points at a minimum density of a 1m survey grid, and must also be able to survey within 1m of an unobstructed bank.

8.5 Open Water

On broads and open water areas, the survey method and equipment must be capable of producing surveyed data points with a minimum density of a 5m survey grid. On each broad the survey should cover all open water areas and include data points obtained as close as possible to the water’s edge.

All X and Y coordinates should be relative to the Ordnance Survey National Grid (OSGB36).

8.6 Deliverables

Given the wide variety of survey equipment, methodologies and potential interpolation or condensing of data to generate the desired output grid, deliverables have been broken down into options based on an increasing gradient of survey data point densities. Option B is optimal for our purposes in rivers and Option A is acceptable for larger open water broads (lakes), but we are willing to receive quotes based on more dense output grids.

Option A

A grid of levels corrected to OS datum. The minimum data point density as derived from the stated survey methodology is a 5m grid and the preferred output format is a CSV file.

Option B

Where an enhanced survey method produces a greater density of data points, the data set should be processed to provide a high quality set of points with a maximum density of a 1m grid corrected to OS datum.Option C



A grid of levels and point cloud corrected to OS datum.

Where a survey method produces an ultra-dense set of data points, these should be processed to provide a set of points with a maximum density of a 1m grid corrected to OS datum. The original point cloud corrected to OS datum should also be supplied.

8.7 Ground Truthing & Calibration

Regular ground truthing is of particular importance for surveys on the broad’s areas due to potentially very soft sediment. The instruments shall be calibrated as appropriate to suit the properties of the water and sediments encountered & calibration method should be included in the tender submission. A record of periodical calibration must be recorded and accompany the task survey.

8.8 Datum

The survey must take into account tidal variation with all levels to be given relative to Ordnance Datum (Newlyn).

Note; the tidal range within the Broads varies from approximately 1.5m close to Great Yarmouth to around 10mm in the upper reaches. In addition the variation in water level may also be affected by rainfall and atmospheric conditions.

8.9 Description of the data

The data provided for each data point should include:

Easting coordinate Northing coordinate Bed level relative to ordnance datum (Newlyn)

All easting and northing coordinates should be given in Ordnance Survey National Grid format (e.g. 631127.6mE, 316615.9mN) and all bed levels should be given in metres. All coordinates and levels should be given accurate to ±50mm (i.e. to at least one decimal place).

The data set should be filtered to remove any anomalous values.



9.0 CONSTRAINTS

9.1 Boat Toll

All craft on Broads Authority waters are required to obtain and display a boat licence. Short term and contractor licences are available. For more information please contact Broads Authority Tolls Office on 01603 610734.

9.2 Plant Movements

Movement of large plant on the Broads navigations requires an escort service by one of the Broads Authority’s ranger patrol vessels. This service will be provided by the broads Authority, but the Contractor must note that this can require notice of up to 5 days.

9.3 Methods and Health & Safety

In addition to the Contract Data and Pricing, the Contractor must provide the following information as a request to prequalification to the evaluation stage.

9.4 Invasive Species

The Broads are vulnerable to the introduction of potentially harmful invasive species. To minimise the likelihood of this the Broads Authority promote a ‘Check, Clean, Dry’ policy. Where practical we request that when entering the Broads from other water bodies, hulls of vessels and plant are first checked and cleaned to remove foreign matter and ideally dry for 48 hours.

9.5 Tides

The Contractor shall assess predicted tides and MET Office forecast weather conditions. The Contractor should programme the Works to avoid foreseeable unworkable conditions. Delays due to foreseeable conditions will not be subject to a compensation event.

9.6 Byelaws

The Broads Authority has certain byelaws enforceable within the Broads navigation area and some affect adjacent waters. These are made under the Norfolk and Suffolk Broads Act 1988 (which was amended by the Broads Authority Act 2009).

Navigation Byelaws 1995 Speed Limit Byelaws 1992

Speed limits are in force throughout the Broads. The limits are 3, 4, 5, or 6 mph, clearly signed on riverbanks and are in statute miles per hour measured 'over the ground'.



Vessel Dimension Byelaws Vessel Registration Byelaws
