    Specifications are written documents that describe the materials and workmanship required for a development. They do not include cost, quantity or drawn information but need to be read alongside other contract documentation such as quantities, schedules and drawings.!

    Specification is an essential part of the design process. A badly written specification can cause major problems for every member of the project team, and can cost the client a great deal of money. A

    well written specification can enhance project delivery and save money.!

    A landscape architect might write a performance specification for particular components of the landscape where the desired result or performance requirements are understood but the method of construction is not. E.g. a landscape architect might understand the particular sports that are required to be played on a proposed grass pitch, and the hours in which the pitch will be in use, but they might not be certain of what construction make up and drainage would be required for it to function effectively. The landscape architect in this case would write a performance specification for the pitch and would allow a specialist contractor to specify its detailed construction.!

    A performance specification states requirements in terms of the required results with criteria for verifying compliance, but without stating the methods for achieving the required results. A performance specification defines the functional requirements for the item, the environment in which it must operate, and interface and interchangeability characteristics.!

    STANDARD SPECIF ICAT ION

    DOCUMENTS

  • Although there is no such thing as a standard specification (i.e. they vary from office to office and from project to project)

    landscape architects do use standard specification documents.

    NBS National Building Specification

    www.thenbs.com

    ICE Institute of Civil Engineering

    www.ice.org.uk

    This specification document is used mainly on landscape projects that have extensive civil engineering works (e.g. large scale infrastructure projects) and is not commonly used by landscape architects.!

    This is the most common standard specification document used in landscape design offices.!

    SPECIF ICAT IONS FOR D IFFERENT WORK STAGES

  • Landscape specifications can be submitted at different work stages in differing levels of detail.

    (Specifications may vary for the size of job and its intended purpose.)

    PLANNING

    Outline specifications are often issued to the local authorities at the initial stage of landscape projects. Outline specifications are not as detailed as specifications for tender or construction, as the local authority will only be interested in understanding the basic components (e.g. plant species and materials) of the project and will not be so interested in the fixtures and fittings. !

    TENDER

    CONSTRUCT ION

    Landscape specifications will be issued to contractors at the tender stage for costing purposes. Depending on the contract and nature of project (e.g. Design and Build) the contractors may offer alternative materials that they feel are the equivalent to what has been specified by the landscape architect. !

    Contract landscape specifications issued for construction will set out precisely the qualities of materials and workmanship of the particular elements and components that are required to be provided in the landscape scheme. The specification will correspond with the contract package of drawings.!

    SPECIFY ING PLANT STOCK

  • EC, Museumpark, Rotterdam

  • S P E C I F Y I N G P L A N T S

    Care must be given when specifying plant stock that sufficient information is provided to the contractors. It is not acceptable to simply specify 1 no. Semi-mature Fraxinus excelsior to be planted in accordance with BS 4043:1966. Semi-mature trees come in a range of girth sizes, heights and forms. The specifier must provide accurate and precise details of plant material within specifications, to ensure that appropriate specimens are procured. Poor quality or unsuitable stock might be sourced if they are not adequately specified.!

    Many professional offices will have developed years of knowledge on the subject of plant procurement and will have built up a library of clauses and specifications for plant material and planting methods. !

    Most offices will refer to and use The Horticultural Trades Associations (www.the-hta.org.uk) NATIONAL PLANT SPECIFICATION (NPS) which is available at the gohelios web-site (www.gohelios.co.uk).!

    Specifiers can use the PLANT SELECTOR tool (www.gohelios.co.uk/plants.aspx) to select species of plants. Specifications for selected plant species can be found here and the specifier can use this to select standard sizes and forms used across the landscape industry.!

    GA+ EC, Bristol Harbourside

  • N A T I O N A L P L A N T S P E C I F I C A T I O N

    Within the NPS you will find that specifications for plants are listed under the following categories:!

    Spec i f icat ion *

    The National Plant Specification (NPS) removes the guesswork in plant procurement by providing a comprehensive and accurate bible for the specification of plants ensuring an effective method of producing rigorously specified plant schedules.* !

    Specifiers using NPS can be sure that the plants are supplied to their exact specification and different nurseries are able to provide like-for-like quotations.*!

    The NPS covers all of the most commonly specified plant groups and defines the criteria used in the specification of plants within each including wild flowers and native species.*!

    N A T I O N A L P L A N T S P E C I F I C A T I O N

  • The NPS (National Plant Specification) sets out the standard minimum requirements for each plant type and species, to ensure that good quality stock is supplied within the landscape industry. Although only a guideline, if landscape architects do not follow the minimum specifications in the NPS, they risk the procurement of inferior quality plant specimens or unsuitable stock (e.g. a tree with three branches). !!Many tree/plant nurseries only grow their stock plants to meet the requirements within the NPS specifications. If landscape architects choose to specify plant sizes that do not align with the NPS, it can be difficult for landscape contractors to source this material. If non-standard plant material is specified within the landscape specification, landscape contractors might see this as a potential cost issue, and may increase their fees at the tender stage to cover this.!!There may be occasional cases when landscape architects choose to specify non-standard or miscellaneous stock within their specification (e.g. a topiary yew hedge trimmed to the shape of an animal). In these cases the landscape architect would liaise with plant nurseries at the design stage to understand the feasibility and costs that would incur as a result of specifying a non-standard specimen. !

    It is normal procedure to start with the largest stock on the project (in this case the trees) and work your way down to the smallest stock.!It is good practice to work in ALPHABETICAL ORDER.!

    N o t e s The landscape architect might include additional notes about the planting outside the schedule for the attention of the landscape contractor. !

  • T rees

    In complex landscape schemes, landscape architects will usually break down the plant schedules included within the landscape specification to make it easier for the contractor to understand different components within the planted landscape, and for ease of pricing. The landscape contractor might wish to send out different plant schedules to specialist nurseries. e.g. a schedule of plants for floating reed beds might be sent over to a specialist reed bed nursery and would not be issued to a tree nursery.!!The following is an example of how the landscape architect might break down plant schedules for a hypothetical landscape project.!

    Shrubs Herbaceous

    Bulbs Lawn

    Reedbeds Marginal aquatics

    Within each plant schedule the specifier will specify species, sizes, forms, age, etc. !Specifiers will often suggest suppliers (with a choice of recommended nurseries) to ensure the procurement of good quality stock.!

    The key should refer to the relevant clauses in the landscape specification.

    Note: It is good practice to keep annotation on contract drawings to a minimum, and to cross refer at all times to the appropriate clauses in the landscape specification. This practice encourages the contractor and involved parties to refer to the most up to date version of the landscape specification, rather than measuring straight off of construction details, or taking information from the contract drawings. Keeping text to a minimum helps to avoid potential confusion, if for example there should be changes to the specified materials in the future. In addition to this, if there are elements within the drawing which are the responsibility of other disciplines (e.g. concrete foundations - civil engineer; external lighting - lighting engineer), the landscape drawing should refer to the specifications of the other consultants. This ensures that the contractor uses the correct specifications and prevents them from relying solely on the landscape contract drawings, which might not have picked up on the latest edits to other parties designs.!!

    Keep annotation to a minimum to avoid potential confusion between the specification and the drawings. This also keeps the drawings free from unnecessary visual clutter.

Consequently, it is necessary to show how details and elements fit together; their interface, relationship and materiality.!!It is common to have to explain your material ideas to Clients who are less attuned to the idea of material combinations, colours, textures, type and composition. In practice this is often done with actual material samples on a board. You should find innovative ways to quickly illustrate your material palette.!!N o t e : P l e a s e r e m e m b e r t o r e f e r e n c e t h e s o u r c e s o f a l l i l l u s t r a t i v e m a t e r i a l .

  • The second part of your project and the second strand of information allowing a project to be built is the specification. This document is read in conjunction with the construction drawings as the Contract Documentation and gives the Contractor guidance on materials, quality and workmanship. NBS defines specification as; Written descriptions of the quality of the built product and its component parts Professional offices use standard specification documents such as NBS or ICE. These documents ensure that all British standards are adhered to. However, to develop your specifying skills, it is initially important to visualise the sequence of operations which the Contractor must follow to build your details. You will work in conjunction with Elise Campbell to develop a text based report which should explain this sequence in sufficient detail for the details that you choose to work on. Crucially, this should be coordinated with your Construction drawings. This text based report will be included on your drawings.!!So the challenge is to envisage all the operations/stages which you will require of a Contractor to successfully build your designs.!
