Review of goals of project, including budget, scope and schedule.

Did the project meet these goals (planned versus actual)?

Budget – The project is over budget by more than normal variance. The original contract amount	was $5,379,385.23. The final contract amount can not be determined at this date.

Schedule – Everyone agreed original schedule was reasonable, currently the project will be substantially complete by December 10, 1999, which is later than the original substantial completion date of October 1, 1999. Two factors for this were utility relocations in the beginning and the sanitary sewer relocation.

Scope – The project has not had a significant scope change.

Discuss various aspects of the project and suggest improvements

A.	Bidding process – Some Lump Sum items should be improved. Traffic Control should be changed from lump sum to itemized per day, due to variations during construction. Lump Sum items like Removal of Structures work best if designer includes a schedule (for information only) for the bid item.

B.	Plan quality – Okay, but think about thinning up some line work to improve readability.

C.	Consultant involvement during construction – Responses were timely and effective.

D.	Construction staking – O’Donnell and City are satisfied with quality of staking. A staking specification in the project manual that includes a detailed scope of work would be helpful. See additional notes below.

E.	Public interaction during construction – Good. Only calls were from Olathe residents concerned about 129th Street access. All felt that pre-construction public meeting was effective.

F.	Temporary easements – O’Donnell had sufficient easements to conduct work.

G.	Quantities and payment – No serious quantity problems. Payment was fine.

H.	Utility relocations – Southwestern Bell relocations delayed initial excavation and wall construction and ultimately resulted in additional project cost for modifying traffic control plans.

I.	Administration – Okay.

J.	Subcontractor performance – Okay.

K.	City staff involvement – Brian performed well.

L.	Construction quality – Good.

5. Open discussion

A.	Surveying and Staking – Use centerline crown instead of back of curb. Also show top of curb elevations and grades at intersections. Put pluses and minuses for curb elevations on typical sections. Put cross slope transitions on profiles. Use 25-foot (10-meter) intervals	on profiles. Plan on furnishing an electronic drawing to the contractor for staking. Put all tie and benchmark descriptions on one sheet (in front of plans). Lay out alignment on a separate sheet and include stations, coordinates and bearings to section corners and PI’s. Include notes and leaders to benchmarks and control points on plan sheets. Include cross slope transition information on intersection details.

B.	Comcast (Jones Intercable) – O’Donnell assisted with relocation design and was very helpful.

C.	Southwestern Bell – Show cross sections at intersections and use match lines if	necessary.

D.	Water District #1 – Label station ranges on lower right corner of plan sheets and cross section sheets.

E.	Utility Meetings – Monthly is better and worth the time and expense for all involved.

F.	Utility Relocations – Specifications need to require clearances between facilities and proposed work. Dan Miller should have information on this. Watch overhead power lines especially in the vicinity of bridge and retaining wall construction and sheet piling.

G.	Irrigation Systems – Systems at 133rd (west side), Ron Bierman’s property, and 127th Street (north side) were not picked up in design and were necessary to reconstruct.

H.	Retaining Wall – The form liner system made it difficult to turn sharp angles. Stepping up and down of liner was not anticipated properly in the design. Also, it was difficult building form liner treatment on both faces of the wall at the same time. The excavation slopes necessary were impractical and made worse by errors on the footing widths. The City and Larkin did not respond appropriately to the contractor about his concerns until he wrote a letter to the City.

I.	Bid Forms – Provide item numbers.

J.	Metric Plans – More difficult to build (same for design).

K.	Traffic Control – Needed to change traffic phasing to allow for traffic prior to substantial completion.

L.	Cross Sections – Take existing out far enough left and right. This would have helped to detect a water trap on the east side of Pflumm.

M.	Quadguard – Installed by Gun-Ko. Looks okay. Larkin checking on nose piece material.

N.	Related Projects – KDOT’s DBE requirements changed. Olathe approved drainable base on the section of Pflumm Road to the north. UD-1 might need to be replaced by something like BD-1 which is cleaner. Profile-O-Graph on these curbed arterials	(KDOT) is a waste of time.

6. Adjourn – 3:30.
