Construction Phase Services

CEC has experienced professionals, technicians, andinspectors, together with the field equipment necessary to provide completeconstruction phase services on a wide variety of projects. These services include:

• As-built drawings
• Certification reports
• Confirmation sampling
• Construction management
• Construction quality assurance/quality control
• Fill placement monitoring
• Health and safety monitoring
• Landfill liner and cap installation monitoring

CEC has provided construction managementservices to our clients beginning with the bidding process through projectcloseout. CEC has developed bid documents,solicited and evaluated bids, and negotiated contracts for site development andenvironmental remediation projects. During construction, CEC can direct contractor activities to meetspecifications and schedule requirements. This effort generally involves the monitoring of project costs andchange orders. Finally, projectclose-out activities, including site restoration, project completion requirements,and final payments can be administered by CEC.

CEC has monitored the construction of a widerange of civil and geotechnical engineering projects. These projects include large earthmovingprojects where CEC was responsible for verifying the acceptability of borrowsources and fill materials, that fill has been placed in accordance withspecifications, and that cuts and fills are properly constructed andstabilized. CEC has monitored the implementation of grouting programs to fillmine voids and stabilize soils and bedrock to reduce the risks of surfacesubsidence. During grouting programs, CEC personnel monitor grout takes andpropose procedural modifications, as necessary, to focus on areas requiringadditional reinforcement.

CEC has also monitored the installation of drainage facilities, such as ponds, ditches, and underdrains, including the construction of landslide correction and earth retaining structures. CEC routinely provides services during the remedial action phase of environmental projects.For UST and waste/ contaminated materialremoval projects, CEC personnel evaluate limits of excavation in the field withmonitoring equipment and obtain confirmation samples for laboratory testing.CEC has also directed and monitored the installation of groundwater extractionand treatment systems and soil venting systems. Our staff includes AHERA-certifiedasbestos inspectors who can monitor removal of asbestos-containing materials. Finally, CEC technicians have performed air monitoring during construction to allow contractors to assess on-site personnel protection requirements.

CEC has also provided CQA servicesduring the construction of waste management facilities.CEC personnel have reviewed material testing reports, monitored placement of earth materials and geosynthetics, and evaluated field test results from geosynthetic installations.This information is compiled by CEC andincluded in the construction certification report prepared for submittal toenvironmental agencies and sealed by a CEC registered professional engineer.

Throughout the construction phase, CEC`s personnel are supported, as necessary, by our staff of technicalspecialists and consultants.As a result, changing field conditions can be quickly addressed to minimize overall project impact.
