Precast Concrete Sample Clauses
The 'Precast Concrete' clause defines the requirements and standards for the use, fabrication, and installation of precast concrete elements in a construction project. It typically outlines the types of precast components permitted, quality control measures, handling and storage procedures, and any necessary testing or certification. For example, it may specify that all precast panels must be manufactured off-site by certified suppliers and delivered according to a set schedule. The core function of this clause is to ensure that precast concrete elements meet structural and aesthetic standards, thereby reducing construction errors and ensuring project quality.

Precast Concrete. (a) The units of measurement shall be:
(i) Beams, slabs, segmental units: number
(ii) Copings, ▇▇▇▇▇ and the like of uniform cross-section: metre
(b) The term "precast concrete" applies to any concrete unit or member cast on site but not in its final position and to concrete units or members manufactured off site.
(c) Item coverage: No separate payment will be made beyond the rates for precast concrete for:
(i) trial mixes;
(ii) reinforcement, cement and processed aggregates;
(iii) formwork, surface finishing, lifting devices and bearing plates;
(iv) forming sockets, holes, grooves, rebates recesses and ducts; and except where otherwise indicated,
(v) handling, laying and fixing the units in position;
(vi) aligning members and units, adjusting levels and soffit profiles, and temporary fixing to prevent displacement;
(vii) cutting and trimming copings, ▇▇▇▇▇ and the like to size.
Precast Concrete. Materials: The preferred exterior materials shall be precast concrete or masonry. Precast concrete systems are acceptable construction materials. Precast systems shall be light in color, and consistent with the intentions of these guidelines. • Precast concrete shall be limited to integrally colored precast, painted or stained precast panels. • No raked concrete panels will be permitted. • Tilt-up concrete panels with accent bands will be permitted. • Tilt-slab concrete buildings shall have no greater than t2” exposed aggregate (which applies to all concrete surfaces), Tilt-slab construction walls may have no more than 300 SF of surface without reveals. Concrete color and aggregate shall be similar to samples as shown by Declarant or accepted in writing by the DRB. Applied stains and paint must be of a consistent architectural finish and maintained as required. Brick, Glazed Brick, Architectural CMU may be used as described below: • Masonry products shall include integrally colored split face units, painted or stained split face units or brick. No standard concrete units shall be permitted. • Glazed brick and glazed tile is for accent and fine details only. • Glass block would not be considered highlight brick and may be used as a masonry product at the owner’s discretion. • Concrete Masonry Units are an acceptable construction material when the masonry units have an architectural finish. Split face block is the suggested finish (fluted block is not an acceptable masonry unit). A smooth finished block is subject to DRB approval or may be used up to 10% of an accent block.
Precast Concrete. 2.17.1 Precast concrete shall comply generally with the requirements given below. All precast units shall be cast on a suitable bed or platform with firm foundation and free from wind, The contractor shall be responsible for the accuracy of the level or shape of the bed or platform, A suitable serial number and the date of casting shall be impressed or painted on each unit. All precast concrete units shall be prepared and fixed as shown in the drawings and as specified in the detailed specification., Concrete mix shall be as specified or as shown in the drawings with machine mixed, machine vibrated and prepared by weigh batching with Contractor's own mix design which shall be approved by Consulting Engineers. IS: 456 Code Practice for Plain and Reinforced Concrete shall be followed as relevant Indian Standard Specification.
Precast Concrete. All precast concrete members to be used in the works, such as covers, lintels, ▇▇▇▇▇, slabs, stairs, etc.., shall be manufactured on site or obtained from approved manufacturer. In either case casting shall be done under the supervision of the Engineer, whose approval of the place and method of casting must be obtained before starting work. If casting is done on the site, the Contractor shall prepare a suitable area near the structure for which the precast parts are intended, and samples of the precast work shall be submitted to the Engineer for approval before proceeding with the manufacture on site. Casting of the precast parts shall be completed in due time so as not to delay the completion of the structures and everything connected therewith. Unless otherwise directed, precast elements shall be of concrete Grade C30P. All precast elements shall be true to dimensions and shapes as shown on the Drawings. Concrete surfaces shall be smooth and all corners square or chamfered, as shown on the Drawings or directed by the Engineer. Lifting lugs and similar metal parts, whether part of the reinforcement steel or not, shall be incorporated in the elements during manufacture. Precast elements shall not be transported or otherwise handled until the end of the curing period, which shall be at least 14 days. Any precast concrete element becoming defective during casting or placing or from any other cause, and rejected by the Engineer, shall be removed from the Site by the Contractor who shall cast new elements to replace the rejected ones, and all expenses in connection therewith shall be borne by the Contractor.
Precast Concrete. A. Precast concrete means precast concrete fabricated as Platform panels or as precast architectural wall base elements at UC, TPSS and Platform utility buildings.
B. Without limiting the requirements set out in Section 5-3.5.1.1.D of this Schedule, architectural precast concrete utilized for Platform panels must also, at a minimum, be fabricated:
1. in accordance with the following standards: a. CSA A23.1
Precast Concrete. All external walls of the building shall have Precast component concrete panels up to the height specified on the drawings.
Precast Concrete. Precast ▇▇▇▇▇, slabs, channel edging and quadrants shall comply with the requirements of BS EN 1339:2003 and with the Drawings. Where the Contractor is permitted to carry out precasting on site, the precast units shall in addition to complying with the relevant BS, be manufactured in steel moulds on a vibrating table or as directed by the Engineer.
