Guidelines for Using the Unit Price Guide

Item Coding and Headings þ The Unit Price Guide is based on the National Schedule of Rates (NSR), which are organized into Work Groups corresponding to those in the New Rules of Measurement (NRM) as published by the Royal Institute of Chartered Surveyors’ (RICS).

The Basis of the Unit Rates:

þ The rates are designed to reflect the actual work that is undertaken and are based on direct labour, plant, and material national list prices. Refer to NSR Guidance Notes, Section 3.2

Labour Rates:

þ Rates include setting out; measuring and cutting to fit; performing the task; disposal of excess material.

þ Labour rates include adjustments to the annual awards announced by the Construction Industry Joint Council (CIJC) and by the Joint Industrial Boards (JIB) for Plumbing & Mechanical Engineering Services and for the Electrical Contracting Industry.

Detailed calculations of all allowances added to the basic rates of wages for craftsmen and labourers are given in the tables located in the Building Guidance Notes Preamble, Section 2.9.1. Refer to NSR Guidance Notes, Section 2.9.1 þ The labour rates have been calculated in accordance with the principles given in the Code of Estimating Procedure published by The Chartered Institute of Building. Refer to NSR Guidance Notes, Section 2.9.1 þ Labour costs are based on workers familiar with and skilled in the performance of the work.

Equipment & Plant Costs:

þ For work that requires the use of equipment or plant, that cost is included in the unit rate.

þ As main national providers to the industry, most of the Plant prices have been obtained from HSS or A- Plant 2019 directory of hire rates. The Plant rates include delivery and return but not for any minimum period of hire except where explicitly stated. Refer to NSR Guidance Notes, Section 2.9.3 þ The equipment and plant cost included in the rates is only for the minimum amount of equipment and plant necessary for the standard installation of the task. Additional plant is allowed with approval from the Owner.

þ Plant costs include all operating expenses such as fuel, electricity, lubricants, etc.

MATERIAL COSTS:

þ All material prices included in the NSR are sourced from the main suppliers in the industry. The list prices of materials, are then used in the calculation of the unit rates (See Building Guidance Notes Preamble, Section 2.9.2 Appendix 3 – Table E: Material Price Supplier List). Refer to NSR Guidance Notes, Section 2.9.2 þ Material costs include the cost of the material, delivery, and all consumables and accessories integral to the installation.

þ Material costs include manufacturer's and/or fabricator's shop drawings.

þ Rates include Material Waste Allowances. These allowances are set out in Table F in the Building Guidance Notes Preamble, Section 2.9.2.1 Refer to NSR Guidance Notes, Section 2.9.2

Complete and In-Place Construction:

þ Unit rates are for complete and in-place construction and include all Labour, equipment/ plant, and material required to complete the task as described in the NSR.

þ Unit rates include all fasteners such as anchor bolts, lag bolts, screws, adhesive, wedge anchors, expansion bolts, roofing clips (excluding hurricane clips) that are required. Fasteners listed separately in the CTC are for use with Owner furnished material and equipment or relocating or reinstalling existing material and equipment.

þ Unit rates exclude more substantial mounting material such as threaded rod or angle iron unless the task description states otherwise.

þ Unit rates for doors and windows, duct work, plumbing fixtures, seamless floors, countertops, flashing, pitch pockets, skylights, curbs, roofing, etc.

excludes sealant and caulking unless stated otherwise in the unit rate.

RAF LAKENHEATH, RAF MILDENHALL, and RAF FELTWELL

Guidelines for Using the Unit Price Guide þ Unit rates include testing, calibration, balancing and the like required to ensure proper installation, construction and performance (e.g. compaction test for backfill, balancing of heating ventilation and air conditioning, pneumatic or hydrostatic testing, soaping of joints, disinfection and flushing, others as required). The above applies to installation of new materials only. Use of owner supplied materials, equipment or tying into existing equipment/piping may justify testing, balancing, etc.

Demolition:

þ Unit rates for demolition include all Labour, equipment and material required for the complete removal of the items; clean-up of the area.

þ The cost of disposal of excavated material will be reimbursed at the unit rates.

þ “Demolishing” includes removing incidental items where if the item being demolished is attached to another item being removed and can be removed as one item, then that item shall not be priced as a separate demolition task, unless the component alone must be demolished to accomplish the task (e.g. demolition of pipe includes pipe fittings unless the fitting must be demolished separately to accomplish the task; demolition of a wood door includes hinges, hardware, closures, kick plates, etc.).

þ The rates contained in the National Schedules do not include any costs associated with working with asbestos. When carrying out work on asbestos based materials, the Contractor shall comply with the Control of Asbestos Regulations 2012 and any subsequent amendments, rules, Approved Code of Practice (ACOP) or guidance. Refer to NSR Guidance Notes, Section 2.6.3 þ The description "reinstall" includes the cleaning and installation of the existing item.

þ Salvageable materials remain the property of the Owner and shall be turned over as directed when specified in the Job Order.

The Coeffciients Include:

*Refer to NSR Guidance Notes, Section 3.3

PRICE VARIATIONS:

þ Contractors may find differences in Labour, and material costs due to certain economic factors.

Variations in Labour cost can also result from Labour efficiency, Labour restrictions, working conditions and local work rules. Variations in material costs can also result from the quantity of material purchased, the existing relationship with suppliers, and because the materials have been discontinued or have become obsolete.

þ While diligent effort is made to provide accurate and reliable up-to-date pricing, it is the responsibility of the Contractor to review and analyze the Unit Rates, and to calculate their Coefficients accordingly, prior to bidding.

GENERAL COSTS:

RAF LAKENHEATH, RAF MILDENHALL, and RAF FELTWELL

Guidelines for Using the Unit Price Guide þ This list is not exhaustive and is intended to provide general examples of cost items to be included in the Contractor's Coefficient as defined in the Contract.

þ The only compensation to be paid to a Contractor for the unit rate tasks will be:

Published X Quantity X Appropriate Unit Rate Coefficient þ No additional payments of any kind whatsoever will be made. All costs not included in the Unit Rates must be part of the Coefficients.

General Interpretations:

WORKING HEIGHT:

þ Rates include scaffolding up to 1.5 metres above the finished floor or stationary working surface.

þ Motorized access platforms are not included in the rates. Motorized access platforms are only allowed with prior agreement from the Owner.

FIELD ENGINEERING:

þ Surveying tasks shall be used only when the Owner requests the Contractor to perform topographic surveys, property line surveys or to establish horizontal and vertical controls. If the Owner provides horizontal and vertical control points within or adjacent to the project site, any other surveying required to complete the work is considered construction staking or layout and the cost thereof is included in the appropriate task.

TESTING:

þ Contractor will be paid for testing existing material, as required by the technical specifications and as directed by the Owner (record tests) at the unit price for the appropriate task. The cost of process quality control testing routinely performed by the Contractor is included in the Unit Rates for the individual tasks.

MISCELLANEOUS:

þ For the purpose of calculating the quantity of a task, quantities are calculated on a per physical location or building address basis. The quantity so determined shall be used for the task, unless the task states otherwise.

þ Whenever there are alternative tasks that may be selected to complete work the Contractor shall select the most practical and economical methods available þ Whenever a proprietary brand names are used the identification is intended to establish a standard. Any item of another manufacturer or vendor which performs satisfactorily the duties imposed by the general design may be considered equally acceptable provided that, in the opinion of the Owner, the material, article or equipment so proposed is an equivalent and is of equal quality, substance and function. The Contractor shall not provide, furnish or install any proposed material, article or equipment without the prior written approval of the Owner. The burden of proof and all costs related thereto concerning the equivalent "or equal" nature of the substitute item, whether approved or disapproved, shall be borne by the Contractor. Refer to NSR Guidance Notes, Section 6.2

SPECIFICATIONS:

þ Specifications for tasks shall be interpreted as follows: All Labour, material, equipment, spare parts, services, and work required by a specification shall be considered part of the unit rate, unless the task description or technical specifications state otherwise.
