Jamaica Plain, MA VAMC Steam Pipe Replacement Project

US Department of Veterans Affairs

Mabbett was awarded a task order under our VA VISN 1 A/E $10M ID/IQ contract to provide professional engineering services to evaluate options and upgrades associated with replacing the deteriorating steam system at the Jamaica Plain VAMC. System components evaluated included steam convectors, fans, controls, steam stations, valves and insulation. Services were completed to prioritize upgrades based on a $3.2M construction budget.

Mabbett conducted preliminary meetings and site survey investigations to define the necessary elements of the project scope of work. Mabbett determined the severity of deficiencies, if any previous deficiencies have been corrected and identified any conditions which may have previously been unreported. The results of the investigations were presented in preliminary layout plans with proposed alternatives to the User Group. Based on User Group meetings and site surveys, Mabbett prepared a basis of design report pertinent to the project requirements within the constraints of the construction budget and consistent with the VA’s project team goals. Through the course of the design phase, Mabbett interfaced with VAMC staff to confirm the details of the scope through a series of meetings and periodic submissions of documents.

Mabbett prepared the 30% Schematic submittal; 60% Design Development submittal; 90% Construction Documents submittal; and 100% Bid [Final] Documents submittal. Each design submission included architectural, mechanical, and electrical disciplines and each discipline requirements were addressed in the Design Analysis, Specifications, Cost Estimate, and Drawings. All design submission requirements were in accordance with the A/E ID/IQ Contract and conformed to the latest editions of all VA criteria/standards/regulations/design guides, along with Commonwealth of Massachusetts regulations.

Mabbett completed an asbestos and lead based paint survey to determine the presence of these hazardous building materials and prepared a survey report that resulted in the basis of hazardous materials abatement drawings which are included in the Bid Documents submittal. Each design discipline investigated the availability of existing building information, and field verified all essential elements pertinent to their discipline. Site conditions were measured, photographed, and documented for areas identified to be renovated and/or impacted. Provided the necessary investigation and inspection of existing utilities to ensure their adequacy.

Mabbett prepared cost estimates to reflect the cost for the project including lead and asbestos removal, required phasing, special field conditions and/or temporary equipment needed during the construction. The final cost estimate accompanied the final design and was submitted for approval to the VA Project Engineer. The 100% Bid Documents submittal also included necessary engineering calculations, independent fire safety/life safety review and bid schedule.

VA Manhattan Campus Environmental Compliance SME Project

US Department of Veterans Affairs, Manhattan VAMC

Mabbett was awarded a task order under our VA OCFM ID/IQ contract for environmental compliance subject matter expertise (SME) associated with pneumatic tube removal and lead-based paint abatement. This project is part of the VA’s compliance program associated with major renovations due to Hurricane Sandy damage. Mabbett is providing SME on this and other renovation projects at the Manhattan campus to ensure that work is done in compliance with the contractor environmental management plan (CEMP) and facility assessment management plan (FAMP).

Under this contract Mabbett is also rendering advice to the VA on environmental compliance issues as they arise and is working with the VAs construction contractors to ensure compliance to the CEMP and CAMP. Mabbett is also assisting the VA with the management of construction waste, the characterization of regulated building materials for off-site disposal, and management of excavated soils associated with construction of a flood wall.

Under this contract Mabbett is also providing additional SME support that include cost reasonableness and due diligence assessments of contractor change order requests and supporting development of independent government estimate and scopes of work for contractor change order requests associated with unforeseen conditions encountered during construction activities.

Hazardous Materials Building Survey

National Parks Service

Mabbett’s Tri-State Regional office was tasked, as a subcontractor, with completing a hazardous materials building survey at a maintenance building within the National Parks Service (NPS) Sandy Hook Unit Gateway National Recreation Area (NRA), Sandy Hook, New Jersey. The buidling was damaged during Hurricane Sandy.

This effort includes development of project plans, initial site survey to help define the survey and sampling program, implementation of the site survey and sampling program, and preparation of estimated quantities of hazardous building materials that will be subsequently used to develop the abatement scope and cost. As part of this effort Mabbett is also providing air quality modeling services that will be used in the National Environmental Policy Act (NEPA) Environmental Assessment (EA) document for the facility being prepared by others.
