Crews on Lafayette's BART bike station and pathway project poured concrete for the new curbs this past week, and the contractor is scheduled to pour the concrete base in the roundabout area starting the week of Sept. 21, the city said in its construction notice Friday, Sept. 18.
The city has posted one of these notices every week since mid-May. Read together, they are the clearest public record of how far the work at the Lafayette BART station has come over the summer.
The bike station itself went in first. Rain pushed the pour back a few days in late May, and the foundation and slab were poured on a Monday in the first week of June. The contractor then formed and placed rebar for the concrete curb wall behind the foundation and poured it the following week.
June and early July went underground. Crews excavated a light pole foundation in front of the bike station, placed storm drain pipe and formed its inlets, installed sleeves for irrigation, and graded the walkway and ramp. The trenches were backfilled at the end of June, and a slurry cement base went down for the curb, gutter, walkway and curb ramp, followed by the concrete itself in early July.
By mid-July the work had shifted to the roundabout area: demolishing the existing asphalt concrete, then grading and compacting the subgrade.
August was mostly the two art poles. The contractor drilled the foundations, set reinforcing steel and formwork, ran electrical conduit to them and poured concrete, while demolition of asphalt and old concrete curbs continued alongside.
The first weeks of September have been curbs: formwork, more electrical conduit and irrigation sleeves, slurry cement base, and concrete poured for the curbs.
For the week of Sept. 21, the city said the contractor plans to pour the concrete base in the roundabout area, install formwork for concrete curbs and a curb ramp, pour a slurry cement base, and pour concrete for curb, gutter and ramp.
Work hours are 7:30 a.m. to 4:30 p.m., Monday through Friday, excluding holidays. Emergency vehicles will be given access at all times, according to the notice.
The city has not announced a completion date. Questions about the project go to Engineering Services Manager Matt Luttropp at 925-299-3247.
