"(1) In this Part "construction operations" means, subject as follows, operations of any of the following descriptions— (a) construction, alteration, repair, maintenance, extension, demolition or dismantling of buildings, or structures forming, or to form, part of the land (whether permanent or not); (b) construction, alteration, repair, maintenance, extension, demolition or dismantling of any works forming, or to form, part of the land, including (without prejudice to the foregoing) walls, roadworks, power-lines, telecommunication apparatus, aircraft runways, docks and harbours, railways, inland waterways, pipe-lines, reservoirs, water-mains, wells, sewers, industrial plant and installations for purposes of land drainage, coast protection or defence; (c) installation in any building or structure of fittings forming part of the land, including (without prejudice to the foregoing) systems of heating, lighting, air-conditioning, ventilation, power supply, drainage, sanitation, water supply or fire protection, or security or communications systems; . . ."
"(2) The following operations are not construction operations within the meaning of this Part — (a) drilling for, or extraction of, oil or natural gas; (b) extraction (whether by underground or surface working) of minerals; tunnelling or boring, or construction of underground works, for this purpose; (c) assembly, installation or demolition of plant or machinery, or erection or demolition of steelwork for the purposes of supporting or providing access to plant or machinery, on a site where the primary activity is— (i) nuclear processing, power generation, water or effluent treatment, or (ii) the production, transmission, processing or bulk storage (other than warehousing) of chemicals, pharmaceuticals, oil, gas, steel or food and drink; (d) manufacture or delivery to site of— (i) building or engineering components or equipment, (ii) materials, plant or machinery, or (iii) components for systems of heating, lighting, air-conditioning, ventilation, power supply, drainage, sanitation, water supply or fire protection, or for security or communication systems, except under a contract which also provides for their installation; . . ."
“36. Drawing all these threads together, and in the context of Sections 105(1) and (2) of the HGCRA, the law and practice can be said to be as follows (the following not intending necessarily to be an exhaustive definition of all requirements): (a) "Construction operations" under Section 105(1)(a) to (c) of the HGCRA involve the various types of work set out in those paragraphs (construction, alterations, repair, maintenance, extension, demolition or dismantling or installation in any building or structure of fittings) forming or to form part of the land. Other provisions such as Section 105(1)(d) to (f) provide that other ancillary operations (cleaning during construction, scaffolding and decoration) also fall within the definition, whether or not it can be said that such work was or was to be "part of the land". (b) One must remember that HGCRA is engaged by a construction contract for the carrying out of "construction operations"; therefore the Act is engaged even if the construction operations are not completed, properly or at all. (c) Whether something forms or is to form part of land is ultimately a question of fact and this involves fact and degree. (d) The factual test of whether something forms or is to form part of the land is informed by but not circumscribed by principles to be found in the law of real property and fixtures. Something which is or is to become a "fixture" will, almost invariably, "form part of the land" for the purposes of the HGCRA. (e) There is some distinction to be drawn between fixtures, that is, things which are attached to buildings or land, and the land itself. In Elitestone, Lords Lloyd and Clyde recognised that distinction between the land and the building itself on the one hand (effectively the same thing) and fixtures fixed to or within a building on the other. (f) To be a fixture or to be part of the land, an object must be annexed or affixed to the land, actually or in effect. An object which rests on the land under its own weight without mechanical or similar fixings can still be a fixture or form part of the land. It is primarily a question of fact and degree. (g) In relation to objects or installations forming part of the land, one can and should have regard to the purpose of the object or installation in question being in or on the land or building. Purpose is to be determined objectively and not by reference simply to what one or other party to the contract, by which the object was brought to or installation brought about at the site, thought or thinks. Primarily, one looks at the nature and type of object or installation and considers how it would be or would be intended to be installed and used. One needs to consider the context, objectively established. If the object or system in question was installed to enhance the value and utility of the premises to and in which it was annexed, that is a strong pointer to it forming part of the land. (h) Where machinery or equipment is placed or installed on land or within buildings, particularly if it is all part of one system, one should have regard to the installation as a whole, rather than each individual element on its own. The fact that even some substantial and heavy pieces are more readily removable than others is not in itself determinative that the installation as a whole does not form part of the land. Machinery and plant can be structures, works (including industrial plant) and fittings within the context of Sections 105(1)(a) to (c) of the HGCRA. (i) Simply because something is installed in a building or structure does not mean that it necessarily becomes a fixture or part of the land. Mr Justice Dyson in the Nottingham Community Housing case was not saying otherwise. A standing refrigerator or washing machine can be installed in a building but nobody, thinking rationally, would suggest that they had become fixtures or part of the land. (j) The fixing with screws and bolts of an object to or within a building or structure is a strong pointer to the object becoming a fixture and part of the land but it is not absolutely determinative. Many of the old cases referred to above demonstrate that such fixings did point towards the object so affixed being part of the land. However, the Gibson Lea case produced a different answer, even though some items were affixed by nails and screws. (k) Ease of removability of the object or installation in question is a factor which is a pointer to whether it is to be treated as not forming part of the land. One can have regard however to the purpose which the object or installation is serving, that purpose being determined objectively. The fact that the fixing can not be removed save by destroying or seriously damaging it or the attachment is a pointer to what it is attaching being part of the land. A significant degree of permanence of the object or installation can point to it being considered as part of the land.” (a) "Construction operations" under Section 105(1)(a) to (c) of the HGCRA involve the various types of work set out in those paragraphs (construction, alterations, repair, maintenance, extension, demolition or dismantling or installation in any building or structure of fittings) forming or to form part of the land.
