PART A – GENERAL


For Use With HKSMM4

For Building Services Works Only :- A Building Services Works are measured in accordance with Section XVII – Mechanical

Installations, Section XVIII – Electrical Installations and Section XIX – Communications / Security / Control Systems of the Hong Kong Standard Method of Measurement of Building Works, Fourth Editions Revised 2018 (hereinafter referred to as “SMM4”).

B Notwithstanding the Classification shown in APPENDIX “A” to Section II – GENERAL

PRINCIPLES of SMM4, Building Services Works shall be classified into systems or installations and given under headings as stated in Annex “A” of this Preambles as appropriate.

C The quantities contained in the Schedules of Rates for Building Services Works are

measured from the Tender Drawings which indicate the design intent and the design intent routing of the services. The quantities are measured flat on plan from point to point as shown on the Tender Drawings and apart from service risers, the measurement does not take into account any additional service runs or fittings required to route locally around structural members or changes in levels etc., to suit the building structure or architectural details and these are required to be allowed for by the Contractor in his rates and prices.

Furthermore, due to the nature of the Tender Drawings many items of detail are not

shown and are required to be allowed for by the Contractor in his rates and prices. These items are further mentioned in these Preambles for Building Services.

D The Tender Drawings show only the design intent routings and position of Building

Services Works. The precise routing and location of all Building Services Works shall be determined by whichever the Contractor is, in accordance with his contractual obligations, is responsible for overall co-ordination of the Building Services and production of Co-ordination Drawings.

E The co-ordination of the Building Services Works shall take into consideration the

requirements of the individual Building Services Installations, based upon the detailed Building Services Installation Drawings, other contractors and specialists works, the spatial constraints of the various elements of the building structure and architectural details, etc. and is required to be carried out to the satisfaction of the Employer’s Representative, the Architect and M&E Engineer.

F No variation whatsoever will be ordered by the Architect in accordance with the

Conditions of Contract as a result of the Contractor being required to reposition or reroute services runs and components from those routes generally indicated on the Tender Drawings in order to comply with the Co-ordination Drawings and any additional costs arising as a result repositioning or rerouting shall be the sole responsibility of the Contractor and shall be deemed to be included in the Contractor’s rates and prices.

G Where reference is made to the terms “Contract” and “Contractor” in these Preambles

for Building Services Works, such terms shall be constructed as meaning “Subcontract” and “Subcontractor” respectively if and when the context so requires.

For Use With HKSMM4

EXCAVATION

A The term “Excavating with open cutting” shall mean excavation works follow the

design as shown in the drawings for the cutting profile at specified angles and volume of excavation shall follow the profile as shown in the drawings.

B Any Site levels, either spot or contour shown on the Drawings are, unless otherwise

stated, reduced to Principal Datum. If the Contractor is not satisfied with the accuracy of these levels, he must give written notice to the Architect before excavations are commenced, otherwise no claim in respect of the inaccuracy of levels will be entertained.

C All excavation has been and will be finally measured from the existing ground level or

the formation level, whichever is the lower, unless different commencement level is specially stated in the measured Bills. All excavations, backfilling and disposal will be measured on the same basis, i.e. of minimum excavation and filling works. The Contractor is, however, at liberty to carry out the works in any sequence provided that any extra costs arising out of any additional works required by the Contractor to suit his own construction requirements are deemed to have been allowed by him in his rates of the items affected.

D The Contractor will be deemed to have visited the Site and to have inspected any trial

holes that may exist and to have satisfied himself, before tendering, as to the nature of the Site, the ground to be excavated and the work required, and to have included in his tender for all types of excavation likely to be met with, and no claim will be allowed for him not having done so.

E The whole of the site formation works have been measured to finished levels as

shown on the drawings. Any additional earthworks required by the Contractor to suit his own construction requirements or to comply with the Architect’s requirements for phasing of the works, if required, shall be carried out at his own expense.



For Use With HKSMM4

EXCAVATION (Cont’d) A It has been assumed, for measurement purposes only, that all excavated materials are

suitable for filling. The rates for filling are to include for provision of imported earth of approved quality obtained from the Contractor’s own source to substitute for any excavated material that may be found unsuitable for filling and for carting away unsuitable materials from site. No adjustment to the quantities will be made in this respect. The onus is on the tenderer to determine before submission of his tender the nature of the soil to be encountered and its suitability for filling. Imported earth for filling shall be measured only when the measured amount of filling exceeds the measured amount of excavation.

B The quantities of excavation etc. have been measured as accurately as possible from
