(Rationale: Modified specification to the satisfaction of both construction, and maintenance.)
2/5/03 – EPSC tabled this item to allow the team to incorporate performance-bond specification verbiage into this specification, and to eliminate excess verbiage not required with performance bonds.
3/5/03 – EPSC tabled this item again, as the team’s resubmitted version did not address all issues raised by the EPSC. If we are going to require a warranty/bond, the EPSC questioned why all the method specifications were needed within this section, along with Secs 805 & 808. Request the team readdress this issue.
4/15/03 – EPSC added verbiage regarding the Missouri Seed Law, and approved again as revised.
5/20/03 – Revised Secs 803.3 and 803.6 to match what was actually approved by the EPSC on April 2. Also removed the performance bond requirements for the same reason. Changes were inadvertently missing in the copy previously sent out to the EPC.
6/2/03 – EPC tabled this to find out from the team: 1) How to guarantee the growth 2) How do we address the contractor replacing accepted sod that later dies without retainage? 3) Sec 108.8.1.2(c) needs to be coordinated with this section. Connie and Jim C. will work with Stacy Armstrong on these issues.
SECTION 803
SODDING
803.1 Description. This work shall consist of preparing the specified areas for sodding and placing approved live sod. furnishing and placing sod on areas shown on the plans or as designated by the engineer.The entire area specified for sodding shall be covered with sod.

Sod shall be moist and shall be placed on a moist earth bed. Sod strips shall be laid along contour lines and adjusted as necessary, beginning at the base of the area to be sodded and working upward. The transverse joints of sod strips shall be broken, and the sod shall carefully be laid to produce tight joints. The sod shall be firmed, watered and refirmed immediately after it the sod is placed. The firming shall be accomplished by use of a lawn roller or tamper. Sod shall be pegged secured on 3:1 (1:3) slopes or steeper, and in ditches and on ditch slopes for the full depth of the ditch, to a maximum of 4 vertical feet (1.2 m), with wood pegs approximately 1/2 inch x 12 inches (15 x 300 mm) driven into ground, leaving about 1/2 inch (15 mm) of the peg above the sod, and spaced not more than 2 feet (600 mm) apart.
