3.1.5.1 Casting
Casting shall be accomplished by methods and equipment that are in conformance with generally
acceptable systems for this type of work.
Forms shall conform to the shape, lines, and dimensions of the members as called for on the
plans, and shall be substantial and sufficiently tight to prevent leakage. They shall be properly
braced so as to maintain position and shape.
All precast concrete shall be manufactured by a plant thoroughly experienced in this type of work.
The manufacturer shall meet all production schedules. Surfaces on which units are cast shall be
level and free from any imperfections detrimental to the surface appearance of the finished units.
Parting compound shall be applied evenly as per manufacturer's recommendations.
Concrete shall be so handled as to prevent segregation of materials and shall be continuously
vibrated during casting, either internally or externally, to achieve proper compaction, finish and
distribution of concrete. All precautions must be taken to keep the reinforcing steel in the proper
locations during placing and consolidation of the concrete. Unless shown otherwise, all reinforcing
steel shall have a minimum cover of 1½". Embedded items shall be accurately placed and
maintained in their proper location during the casting operation. Special inserts or other devices for
handling of panels for the convenience of the manufacturer shall not be exposed to view after
members are erected. Embedded anchors, inserts, plates, angles and other cast-in items shall have
sufficient anchorage and embedment for design requirements.
3.1.5.2 Curing
Concrete shall be protected from the weather and maintained at 50oF to 75 oF in a moist condition
for at least the first seven (7) days after placing unless steam curing is employed.
Concrete may be steam cured after an initial set has taken place. The steam temperature shall not
exceed 160 oF, and shall not be raised from the ambient temperature at a rate exceeding 40 oF per
hour. The steam cured unit shall not be removed from the forms until sufficient strength is
obtained for the unit to withstand any structural strain that may be imposed during the form
stripping process. After the stripping of forms, further curing by means of water spraying or a
membrane curing compound may be used. This compound shall conform to ASTM C-309.
3.1.5.3 Dimensional Tolerances
The dimensional tolerances of structural members shall not be greater than 3% of the specified
dimensions. The internal dimensions of the vault shall be held to within 1% of the designed
dimension. When a structure is composed of one or more components, the space in the joint
between elements shall be uniform to a maximum tolerance of 1/16".
3.1.5.4 Inserts
All threaded inserts placed in the concrete for use by the purchaser shall be free of dirt to a depth
of 2-1/2 times the thread diameter, and shall be protected from rust. The manufacturer shall
specify the maximum allowable loads that may be placed on all inserts.
3.1.5.5 Gaskets
Structures composed of one or more elements and provided with gasket seals between the
elements, shall when assembled exert uniform pressure on the gasket through its entire length
sufficient to provide a watertight seal upon test.
3.1.6 GUARANTEE
The contractor shall guarantee the vault and lid for a period of two years after completion against
defective workmanship and materials. The determination of the necessity during such guarantee period
for the contractor to repair said vaults and lids shall rest entirely with the Light and Power Utility, and the
decision upon the matter shall be final and obligatory upon the contractor.

4.2 QUALIFICATION TESTS
4.2.1 Concrete
The manufacturer shall test concrete in accordance with A.C.I. 318 and in addition shall for each vault
make two (2) cylinders which shall be cured under field conditions. All cylinders shall be tested by an
approved independent testing laboratory and a certificate of these tests shall be a part of the
manufacturer's permanent record. In addition, one (1) copy of the certificate shall be provided to the
Utility's representative at the time of delivery.
4.3 FUNCTIONAL TESTS
4.3.1 Dimensions
All dimensions shall conform to the drawings with allowable tolerances as specified in Paragraphs
3.1.5.3 and 3.2.5 of this specification.
4.4 Finish
The finish shall be the result of casting against approved forms using care in the cleaning of forms, design
of concrete mix, placing, and curing.
4.5 Defects
Small surface holes caused by air bubbles, normal form joint marks, and minor chips and spalls will be
tolerated. Honeycomb (due to lack of proper consolidation by vibration) will be cause for rejection. All
cracks which penetrate the thickness of any member shall be deemed evidence of partial failure and shall
be cause for rejection of the member.
4.6 TEST METHODS - QUALIFICATION TESTS
Concrete samples shall be taken in accordance with ASTM C172. Concrete cylinders shall be molded and
laboratory cured in accordance with ASTM C31 and tested in accordance with ASTM C39. Field cured
cylinders shall be in accordance with Section 9(c) of ASTM C31. Other sample monitoring systems may be
used if approved by City of Fort Collins Utilities.
4.7 TEST METHODS - FUNCTIONAL TESTS
4.7.1 Dimensions
All dimensions and location of inserts and openings shall be checked using a standard tape measure.
4.7.2 Finish and Defects
A visual inspection shall be deemed adequate to determine the quality of the finish and the extent of the
defects. Where cracks of questionable nature exist, the manufacturer may be required to load test the
member in accordance with ACI 318. In any event, all members shall be watertight.
5 DELIVERY
Manufacturer is responsible for delivery and final placement of vaults at job site; it is expected that the
manufacturer provide a crane capable of lifting each vault section. Manufacturer is responsible for delivering, with
vault, the appropriate amount of preformed concrete joint sealant (i.e. Ram-nek). Care shall be taken in loading,
transportation, and setting precast vaults. Members shall be handled in such a manner as to prevent excessive
stresses, spalling, or cracking. Edges shall be protected from staining, chipping or spalling. Manufacturer’s
dispatch shall coordinate with Utilities line crew foreman to schedule delivery date and time. Actual delivery of vault
to job site shall not be in excess of 45 minutes past agreed-upon delivery time. The manufacturer shall be
responsible for all incurred costs due to tardy delivery, which includes, but is not limited to extended traffic plans,
charges from the back-fill company and labor charges. These additional costs will be deducted from the original
Purchase Order or back-charged to the manufacturer.
