“The said petitioners have on several occasions visited your offices on a follow-up on the investigations based on their petition, but no communication over the progress, if any, has been forthcoming from your end,” read the letter. The petition, which was received at the EACC headquarters on March 10 that same year, was drafted by former area MP Moses Muihia, a Mr Moses Njuguna Kabati, Isaac Kamau Karanja and Elijah Karanja Giacharu, on behalf of residents.
#Cdf properties update
Ideal for use in tight or restricted areas where placing soil fill is difficult.The investigators are also demanding to be furnished with signed tender committee award minutes, professional opinion reports, award notification letters to the successful bidders, payment vouchers, invoices and other attachments, certificate of work completions and any other relevant information.Ī group of residents, through lawyer MA Ondieki, wrote to Mr Mbarak on February 5, demanding an update on the progress made on a petition they presented to the commission on March 9, 2017, demanding investigations into the NG-CDF committee. It is used where speed of construction is advantageous and where better performance is required. CDF Properties, LLC was formed on Friday 4th January 2008, so this company age is fourteen years, two months and one day. Can Be color-coded for utility identification CDF Properties, LLC operates as a Limited Liability Company under company SosId number 1020256.Reduced in-place costs- less labor & equipment.
Other Concerns is compaction around pipes for support. Study indicates that 65% of utility cut restorations were unsatisfactory. Improper backfill is the number one complaint of public works directors. Lack of compaction causes most call-backs to repair settlement problems. Therefore, specification offers flexibility of its mix design, minimum mix design testing and little or no field testing required. Therefore, CDF is always bounded between 0 and 1. So, the more the concrete is wetter, the more it is better. As per the definition of CDF, it is a probability function P(X x) and any probability must have a value between 0 and 1. The less water does not equate to faster hardening and too little water will not allow proper settlement. It has low cementitious mix, does not hydrate and it settles and dewaters. It has high lump (nearly 9 inch) but the strength is low, commonly 100 PSI (0.7 Mpa) in 28 days. Main Ingredients of flowable fill concrete are cement, sand, water with fly ash GGBF slag, stable air generators. The materials and mix design for the flowable fill should be designed to produce a comparable compressive strength to the surrounding soil after hardening, making excavation at a later time possible to produce the compressive strength indicated for the placed location, as determined by the Engineer.

Unless otherwise noted, flowable fill installed as a substitution for structural earth fill, shall not be designed to be removed by the use of hand tools. This mixture is capable of filling all voids in irregular excavations and hard to reach places (such as under undercuts of existing slabs), is self-leveling, and hardens in a matter of a few hours without the need for compaction in layers.įlowable fill is sometimes referred to as controlled density fill (CDF), controlled low strength material (CLSM), lean concrete slurry, and unshrinkable fill.įlowable fill materials will be used as only as a structural fill replacement on VA projects. 🕑 Reading time: 1 minuteFlowable fill concrete is a self-compacting cementitious slurry consisting of a mixture of fine aggregate or filler, water, and cementitious material which is used as a fill or backfill in lieu of compacted-soil backfill.
