Additional Factory Facilities Room Used area of 172.5㎡(5m*34.5m), illumination intensity should be not less than 200lx Water chiller/air compressor/vacuum pump/process cooling water, the roof placed cooling towers request bearing 750KG/m2
Concrete Construction. See Table 1705.3 for detailed information regarding inspection. Major areas under steel construction are:
Concrete Construction. At this time, SCG does not know the contractor’s concrete pouring sequence or schedule. However, SCG anticipates approximately eight (8) periodic inspections of the reinforcing bars prior to the pours. SCG anticipates four (4) separate concrete pours for the structural concrete elements (footings and walls). The concrete pours require continuous inspections and concrete quality control testing. In total, another eight (8) is estimated to perform all concrete cylinder breaks and to provide the reports. The contractor shall provide SCG with a convenient and adequate staging and curing area for the concrete test cylinders. Compressive strength testing will be performed on the concrete cylinders. • SCG estimates another five (5) full days to perform the additional continuous inspections for the adhesive anchors, prestressed concrete and grouting as listed on sheet S1.0. • SCG scope and budget shall include attending the pre-construction meetings, periodic and continuous inspections, sampling the concrete, performing the compressive strength tests, and the completion of the compliance reports. • The suggested budget to complete this scope of work is $12,514.
Concrete Construction. Add the following: In some locations the pipeline to be replaced is located under various concrete improvements such as sidewalk, driveway, curb, gutter, etc. Contractor shall sawcut the existing concrete to be removed and replaced. Replacement of existing Portland cement concrete curb, gutter, sidewalk, and driveway shall conform to City Standard Details ST 1 through 7.
